A full detailed description of this will be done later... is several days
of work. Here's a summary:
Render:
- Full cleanup of render code, removing *all* globals and bad level calls
all over blender. Render module is now not called abusive anymore
- API-fied calls to rendering
- Full recode of internal render pipeline. Is now rendering tiles by
default, prepared for much smarter 'bucket' render later.
- Each thread now can render a full part
- Renders were tested with 4 threads, goes fine, apart from some lookup
tables in softshadow and AO still
- Rendering is prepared to do multiple layers and passes
- No single 32 bits trick in render code anymore, all 100% floats now.
Writing images/movies
- moved writing images to blender kernel (bye bye 'schrijfplaatje'!)
- made a new Movie handle system, also in kernel. This will enable much
easier use of movies in Blender
PreviewRender:
- Using new render API, previewrender (in buttons) now uses regular render
code to generate images.
- new datafile 'preview.blend.c' has the preview scenes in it
- previews get rendered in exact displayed size (1 pixel = 1 pixel)
3D Preview render
- new; press Pkey in 3d window, for a panel that continuously renders
(pkey is for games, i know... but we dont do that in orange now!)
- this render works nearly identical to buttons-preview render, so it stops
rendering on any event (mouse, keyboard, etc)
- on moving/scaling the panel, the render code doesn't recreate all geometry
- same for shifting/panning view
- all other operations (now) regenerate the full render database still.
- this is WIP... but big fun, especially for simple scenes!
Compositor
- Using same node system as now in use for shaders, you can composit images
- works pretty straightforward... needs much more options/tools and integration
with rendering still
- is not threaded yet, nor is so smart to only recalculate changes... will be
done soon!
- the "Render Result" node will get all layers/passes as output sockets
- The "Output" node renders to a builtin image, which you can view in the Image
window. (yes, output nodes to render-result, and to files, is on the list!)
The Bad News
- "Unified Render" is removed. It might come back in some stage, but this
system should be built from scratch. I can't really understand this code...
I expect it is not much needed, especially with advanced layer/passes
control
- Panorama render, Field render, Motion blur, is not coded yet... (I had to
recode every single feature in render, so...!)
- Lens Flare is also not back... needs total revision, might become composit
effect though (using zbuffer for visibility)
- Part render is gone! (well, thats obvious, its default now).
- The render window is only restored with limited functionality... I am going
to check first the option to render to a Image window, so Blender can become
a true single-window application. :)
For example, the 'Spare render buffer' (jkey) doesnt work.
- Render with border, now default creates a smaller image
- No zbuffers are written yet... on the todo!
- Scons files and MSVC will need work to get compiling again
OK... thats what I can quickly recall. Now go compiling!
- Moved all 'render pipeline control' options out of the Material panels
into the (now renamed) "Links and Pipeline" Panel. These are the options
that are not per material-node, but global for the entire Material tree.
It includes ZTransp, Zinvert, Strands, Halo, Wire, etc.
- To further make Node editing clear, when you enable Nodes for the first
time, the link button to the first Material node is drawn red, to note
that here needs something linked or added.
- Protected Node editing for Library data
- Fixed header buttons to work OK for Node Window
To enable dynamic tiff support.
I had to fix some of the logic in the fileselect box for icons,
I also expanded the patch to look in various default locations for
a dynamic libtiff.so/libtiff.dll
and look at the env variable BF_TIFF_LIB if it can't find it automatically.
If unable to load the library it prints a message about setting BF_TIFF_LIB
to the console.
I haven't been able to test it on a lot of platforms but hopefully it
will just work ;) I added the files to scons but have not had a chance to
test that as well.

errors, switched MEM_set_error_stream to MEM_set_error_callback
that calls a function to print result instead of just giving
a FILE *
Note: requires intern recompile
had to add a new feature to the 3d window, to collect "after draw" objects,
which get drawn as last, after a clear of the zbuffer.
Same method can be used for nice OpenGL transparent draw, the system is
ready for it, do that later.
The huge commit is caused by cleaning up globals from struct Global. Many
variables were unused or just not needed anymore. Did that to move the ugly
G.zbuf to where it belongs, in the View3D space struct. :)
- Made Blender.event var (previously only used by script links) hold ascii value -- where it applies -- of current event during events callback registered with Draw.Register(gui, events, button_events). Useful for gui scripts like Campbell's Python console. No problem using this var to hold the value, since in gui scripts it was not used (always None).
- Updated Window and Window.Theme with new theme vars and the Time space.
- Script links:
-- Added "Render" event for script links (runs twice, second time as "PostEvent", for clean-up actions). Now FrameChanged links don't run when a single pic is rendered.
-- Added "Enable Script Links" button in the script buttons tab. Now this bit gets saved in .blends along with the rest of G.f, so users can define per .blend if they are on or off by default. "blender -y" also disables all slinks as happened before with OnLoad ones only.
-- Other small changes in the script buttons tab:
When a link is added (button "new"), it becomes the active one for the window, no need to press a button to reach it.
Also, a pupmenu showing all available texts is shown when "new" is pressed, so users can choose a text w/o having to type. Cancel the popup to leave the string button empty (link exists, but has no script assigned). A pulldown would be better UI-wise, but it's kinda weird to show both scripts and normal texts (Blender doesn't differentiate them) in a script links pulldown. With a popup we can show only texts ending in ".py" (not done in this commit, need opinions) and if the script has no or another extension, case of many in old and current .blend's, there's still the string box for writing its name.
-- Implemented Ton's space handler script links:
Right now only for the 3d View, but it's trivial to add for others. There are two types: EVENT, to receive 3d View events from a chosen window and DRAW, to draw on the window. Ton's idea was to give scripts a controlled way to integrate better within Blender.
Here's how it works:
- scripts must have a proper header, like:
# SPACEHANDLER.VIEW3D.EVENT
and then they are shown in 3d View's View menu, "Space Handler Scripts" submenu. Check (mark, click on it) a script to make it active.
EVENT handlers should consult the Blender.event var to get the current event, which can be compared with values from the Draw module:
import Blender
from Blender import Draw
evt = Blender.event
if evt == Draw.AKEY:
print "a"
elif evt == Draw.LEFTMOUSE:
print "left mouse button"
else:
return # ignore, pass event back to Blender
Blender.event = None # tell Blender not to process itself the event
DRAW handlers are free to draw to their owner 3D View. OpenGL attributes and modelview and projection matrices are pushed before running the handler and poped when it finishes.
To communicate between EVENT and DRAW handler scripts we have the Blender.Registry module, as always.
Still need to code some nice example, which should also serve to test properly space handlers. Simple tests went fine.
- doc updates about the additions.
=======
Note: the UI part of the space handlers and script links is of course open for changes, I just tried to make it understandable. Probably we won't use the scriptlinks icon for "None Available" (check 3d View -> View -> Space Handler Scripts), though it hints at what space handlers are. The tooltips may not be accepted either, since other menus don't use them. Opinions welcomed.
source/creator/creator.c
changed ifdef's around fpe_handler to match when its actually used.
intern/SoundSystem/intern/SND_AudioDevice.cpp
Changed: SND_SoundObject* oldobject = oldobject = pIdObject->GetSoundObject();
to: SND_SoundObject* oldobject = pIdObject->GetSoundObject();
intern/SoundSystem/openal/SND_OpenALDevice.cpp
removed unused var.
source/blender/blenkernel/intern/mball.c
initalized a couple of vars that might have been used uninitalized.
The rest were changing types to match, most of them were something like
was short * should have been unsigned short *.
Kent
removed leftovers from Freeimage/Imagemagick experiments
and removed stuff from a Quicktime for linux implementation.
Also removed the (win32) Fullscreen button from the UI and
disabled the corresponding commandline option. The code is
still present to reenable the option whenever the ATI issues
get solved.
Render:
- New; support for dual CPU render (SDL thread)
Currently only works with alternating scanlines, but gives excellent
performance. For both normal render as unified implemented.
Note the "mutex" locks on z-transp buffer render and imbuf loads.
- This has been made possible by major cleanups in render code, especially
getting rid of globals (example Tin Tr Tg Tb Ta for textures) or struct
OSA or using Materials or Texture data to write to.
- Made normal render fully 4x32 floats too, and removed all old optimizes
with chars or shorts.
- Made normal render and unified render use same code for sky and halo
render, giving equal (and better) results for halo render. Old render
now also uses PostProcess options (brightness, mul, gamma)
- Added option ("FBuf") in F10 Output Panel, this keeps a 4x32 bits buffer
after render. Using PostProcess menu you will note an immediate re-
display of image too (32 bits RGBA)
- Added "Hue" and "Saturation" sliders to PostProcess options
- Render module is still not having a "nice" API, but amount of dependencies
went down a lot. Next todo: remove abusive "previewrender" code.
The last main global in Render (struct Render) now can be re-used for fully
controlling a render, to allow multiple "instances" of render to open.
- Renderwindow now displays a smal bar on top with the stats, and keeps the
stats after render too. Including "spare" page support.
Not only easier visible that way, but also to remove the awkward code that
was drawing stats in the Info header (extreme slow on some ATIs too)
- Cleaned up blendef.h and BKE_utildefines.h, these two had overlapping
defines.
- I might have forgotten stuff... and will write a nice doc on the architecture!
patching versions for UI settings.
Currently four different levels of routines for .blend file reading exist;
/* interface level */
1) BIF_init() -> calls 3
2) BIF_read_file() -> calls 11, optional 4
3) BIF_read_homefile() -> calls 11 or 12, and then 4
4) init_userdef_file()
/* kernel level */
11) BKE_read_file() -> calls 21, and then 14
12) BKE_read_file_from_memory() -> calls 22, and then 14
13) BKE_read_file_from_memfile() -> calls 23, and then 14
14) setup_app_data()
/* loader module level */
21) BLO_read_from_file() -> calls 24
22) BLO_read_from_memory() -> calls 24
23) BLO_read_from_memfile() -> calls 24
/* loader module, internal */
24) blo_read_file_internal()
Note:
- BIF_read_homefile() has additional UI initialize calls, like windows fullscreen and executing commandline options
- Reading from memory (12) only happens for the compiled-in .B.blend
- The "memfile" here is a name I gave to the undo "file" structure. Which is constructed out of memory chunks with basic compression features.
- the kernel function setup_app_data() sets globals like "current screen" and "current scene".
So far, so good. The levels as mentioned here clearly distinguish UI from kernel, and should enable for example game loading (runtime) or background (no UI) loading. In the past years however, 'bad level' dependencies were added, and especially the patches for 'file versions' were added in too many places. The latter is evidently a result of the problem that the "UserDef" struct cannot be initialized/patched if there's not a need for a UI.
Here's how the flow goes in four different cases:
----- Starting up Blender, in foreground with UI --------------------
- creator/creator.c, main() -> calls 1
- If the commandline contains a filename, it calls 11
----- Starting up Blender, in background without UI --------------------
- creator/creator.c, main() -> calls 11 if the commandline has a filename
Note: no Userdef is read, nor initialized. Please note that this was already an existing problem for using Yafray, not setting proper file paths in background mode. The Yafray paths don't belong in the User menu.
----- Starting up Blender as a runtime executable --------------------
This only has calls to 22
----- Loading a file from within the UI (with F1, CTRL+O, using pulldowns) -----
Only calls allowed to 2. It detects if a UserDef has been read too, and in that case the init_userdef_file() will be executed.
Hope this is understandable :)
-Ton-
- Blender.Window: added function GetPerspMatrix() (Tom Musgrave's patch, thanks);
- added Chris Want's patch to tell argc, argv to the Python interpreter (thanks, Hos);
- Blender.Image: added image.glFree() to free textures bound by the recently added
image.glLoad() (both suggested by Campbell Barton -- thanks, with these Blender can
be used to load textures for scripts);
- Blender.Sound: removed for now at least a few get/set methods of vars that can't be
accessed via interface;
- renamed Get/makeActive to Get/setCurrent in Blender.World (actually added alias for
now), same in Blender.Sound: renamed makeActive to setCurrent. Stephen Swaney
pointed this some weeks ago, we should stick to one naming convention.
- added documentation for Sound and Window.Theme modules and the other added
functions, made other small updates.
- Blender.Object: made 'worldspace' become the default output of .getMatrix and .mat/.matrix:
after reading a discussion on blender.org's Python forum where eeshlo mentioned the
pre 2.34 default was worldspace, I took a better look at Blender's relevant code,
confirmed, talked to Theeth about this and as he suggested am changing the default
back to 'worldspace'.
those who work with visible dock where experimenting slowdown of UI when
blender window was overlapping dock.
now :
- check available space excluding dock
- create window with a 10 pixels border
- maximised mode is only 1 click away
This code is fixing only. Will review that when consensus will be found
about how we should create the window.
if video card is open GL accelerated and has 16 Mo or more
start window in maximized mode wich is a full screen mode
but keeping access to other windows and sytem menu items
older comps start as usual
- BPython: finishing object and nmesh .setMaterials commit, fixing two bugs. Also fixed a crash with object.track (pointer wasn't checked for validity). All based on reports and patch by Yann Vernier, thanks again.
- small additions and fixes to enable the demo mode;
- Added sleep() to Blender.sys and 17 new functions to Blender.Window module:
things to help demo script writing and as a bonus read / write access to Blender's input event queue;
- updates in docs, those interested please check Window.py in python/api2_2x/doc/ to read about the new Blender.Window functions.
----
Demo mode should be working well now for (I) playing rt animation -- aka ALT+A -- and (II) rendering pics and anims and playing anims. I'll still add access to radiosity data and functions.
PS: Joseph Gilbert made (II) possible with the Scene.Render module he added for 2.32. He's been coding great things for bpython, so I'd like to take the chance to point that and thank him here.
- hotkeys, obdatacopier and renameobjectbyblock, all from Jean-Michel Soler (jms);
- bevel_center by Loic Berthe, suggested for inclusion by jms;
- doc_browser, by Daniel Dunbar (Zr)
Thanks to them for the new contributions!
(I included doc_browser at 'Misc' because only users interested in script writing would actually use it, but it could also be under 'Help'. Opinions?)
BPython related:
- Added scriptlink methods to object, lamp, camera and world.
- Object: added object.makeTrack and object.clearTrack (old track method).
- sys: made sys.exists(path) return 0 for not found; 1 for file, 2 for dir and -1 for neither.
- doc updates and fixes.
- made ONLOAD event work. G.f's SCENESCRIPT bit was being zeroed in set_app_data.
- Blender: updated functions Load and Save to support the builtin importers and exporters besides .blend (dxf, videoscape, vrml 1.0, stl, ...)
- Draw: added mouse wheel events.
- Scene: added scene.play to play back animations (like ALT+A and SHIFT+ALT+A). Makes a good counter, too, when the 'win' attribute is set to a space that doesn't "animate".
The scene.play() addition and the fix to ONLOAD scriptlinks is part of the work for a Blender demo mode. It already works, but I'll still add support for Radiosity calculations and fix a thing in main(): it executes onload scripts too early (BIF_Init), giving funny results in alt+a animations and renderings when firing up Blender. Loading after the program is up has no such problems. When I finish I'll post examples of demo mode scripts.
This was caused by calling sound_init_audio() at startup. In situations
where Blender was first started, or when other applications used memory,
this could take 5-15 seconds.
I have moved the init call to 'start ketsji', and made sure any call
to an audio play routine will invoke an init as well.
Tested with engine and loading/play sound in F10 menu. I don't know how
the BlenderPlayer handles it... should be investigated.
Result: At OSX Blender starts in a second again! :)
- tentative fix for scripts with CR/LF endings and split lines:
in 2.32, the ac3d and vrml2 exporters, for example, had lines
split with '\\\\' and so gave syntax errors when executed on Win
platforms, because the scripts bundled with Win binaries had dos
line endings.
- Chris Keith has written code to execute Python scripts from the
command-line, with '-P ' switch: "blender -P filename":
a Blender.Quit function was also added, so Blender can quit after
running the script (end the script with Blender.Quit()), but there's
still work to be done in this part, including adding more functions,
to load / save .blend files and to run scripts. More testing and
discussions are necessary.
Thanks Chris, for both your contributions and your patience, since I
wasn't available to check / commit this for a while.
* Blender static now links. By default this option is disabled on all
platforms. Simply set the option in config.opts to 'true'.
* Added the following flags to config.opts:
- HOST_CC. This is the C compiler for the host platform. This value is the
same as TARGET_CC when not cross compiling.
- HOST_CXX. This is the C++ compiler for the host platform. This value is
the same as TARGET_CXX when not cross compiling.
- TARGET_CC. This is the C compiler for the target platform.
- TARGET_CXX. This is the C++ compiler for the target platform.
- TARGET_AR. This is the linker command for linking libraries.
- PATH This is the standard search path
All SConscript files have been updated to reflect these changes. Now it's
possible to change only the root SConstruct file, and all compiler specific
variables are passed automatically to all SConscript files. Of course, this
does not apply to makesdna because there the host and target platform is
different from all other libraries.
To pass a variable that applies to all platforms, all we now have to do is
set the correct value in library_env
Note: as usual, to get the latest options in the config.opts file, first
remove your version.
* Added the options to build (configurable via config.opts):
- blender dynamic (default enabled),
- blender static (default disabled). Not working because of a linking order
problem. The /usr/lib/libGL.a and /usr/lib/libGLU.a flags need to be
appended at the end of the link command, not directly after the linker.
Mailed the SCons mail list for a possible solution.
- blender player (default disabled). Not implemented yet anyway.
- blender plugin (default disabled). Not implemented yet anyway.
* Added the following variables to the config.opts:
- OPENGL_STATIC. This flag is only needed when building blender static.
- USE_BUILDINFO (true/false). Display build information in the splash
screen. When enabled, it will always rebuild source/creator/buildinfo.c,
so for compilation speed reasons, it is not adviced to enable this all the
time.
I had to make some adjustments specifically for the windows build
(winblender.res) file. This file is only compiled when building the dynamic
blender. I hope this is correct.
-- this finishes the heavier part (not counting tweaks and possible bugs) of
letting scripts be accessed from Blender menus. Will explain more in emails
to bf and bpython lists, but just check
source/blender/python/BPY_menus.[hc] and
source/blender/src/header_info.c and header_script.c for details.
Scripts need a small update (registering info, basically a header) to be used.
Scripts dir (user pref file paths: Python) must be set.
Materials are exported the best we can do by now. It will look almost as in
blender except for the missing procedural textures and some minor issues.
You have to tweak normal modulation amount to get the desired result cause
is not the same in yafray.
We added a panel in render space to adjust some yafray settings (GI and so)
Also we export transparency and reflection using new raytracing settings,
but that will be changed and improved soon.
Remember that you have to set YFexport path in user defaults and yafray must
be on path (version 0.0.6)
We added the "yafray" button to activate all this stuff in the render window.
Panel and settings are only shown when checked.
So now when activated the code calls yafray export instead of the internal
renderer and finally the resulting image is loaded back into render window's
buffer. So animation is also possible and results can be saved using blender
usual scheme.
Updated the Make environment to point to the correct location. The include
paths were still pointing to source/blender/bpython/include while it should be
source/blender/python.
I did not encounter the build problems because I'm always working with the
autoconf build environment.
layout. Old size was 800x600, just not too nice
New size is 900x768. this default small size is for older macs that
dont allow full size 32 bits opengl windows... silly er! :)
again. You'll have to do it twice... first CTRL+C will send an internal
break (exit render loops)
- I prefer this in foreground mode too, but Python uses it as well, to
escape from loops. We have to fix this once.
Removes ssl from blender.
makes the following directorys not needed anymore:
blender/intern/keymaker
blender/source/blender/src/pub
blender/source/blender/encrypt
blender/source/blender/decrypt
blender/source/blender/sign
blender/source/blender/verify
It works with The Nan Makefiles and autoconf, could whoever is working
on the other build systems update them so we can nuke those directorys?
They won't do anything but I figured I'd leave them in for a week or so
to make things easyer on people.
