should be no functional changes yet. UV, tangent and intercept are now stored
as attributes, with the intention to add more like multiple uv's, vertex
colors, generated coordinates and motion vectors later.
Things got a bit messy due to having both triangle and curve data in the same
mesh data structure, which also gives us two sets of attributes. This will get
cleaned up when we split the mesh class.
Note: this doesn't work yet for everything with latest stable bullet (2.81), need to look into why and likely apply some patches upstream.
However I managed to link blender by disabling some features, likely it can be made to work without too much trouble.
This commit implements highlight of tiles which are being currently
rendered for both Blender Internal and Cycles (and should be possible
to use it for other external engines as well).
Couple of implementation details:
- Added one extra boolean flag to render engine which should be set
to truth if render engine wants to highlight tiles. If so, property
use_highlight_tiles should be set to True.
- Render Part's ready boolena was changed by status enum, which could
be NONE, IN_PROGRESS and READY. All render part with IN_PROGRESS
status will be highlighted in image editor.
- For external engines render part's status is filling in automatically.
Initially all render parts has got NONE status, then one external
engine acquire render result, corresponding part will change status
to IN_PROGRESS. As soon as render result is finished, corresponding
render part will change status to FINISHED
This should make it easy to highlight tiles for other engines as well.
This assumptions are now made:
- Internally float buffers are always linear alpha-premul colors
- Readers should worry about delivering float buffers with that
assumptions.
- There's an input image setting to say whether it's stored with
straight/premul alpha on the disk.
- Byte buffers are now assumed have straight alpha, readers should
deliver straight alpha.
Some implementation details:
- Removed scene's color unpremultiply setting, which was very
much confusing and was wrong for default settings.
Now all renderers assumes to deliver premultiplied alpha.
- IMB_buffer_byte_from_float will now linearize alpha when
converting from buffer.
- Sequencer's effects were changed to assume bytes have got
straight alpha. Most of effects will work with bytes still,
however for glow it was more tricky to avoid data loss, so
there's a commented out glow implementation which converts
byte buffer to floats first, operates on floats and returns
bytes back. It's slower and not sure if it should actually
be used -- who're using glow on alpha anyway?
- Sequencer modifiers should also be working nice with straight
bytes now.
- GLSL preview will predivide float textures to make nice shading,
shading with byte textures worked nice (GLSL was assuming straight
alpha).
- Blender Internal will set alpha=1 to the whole sky. The same
happens in Cycles and there's no way to avoid this -- sky is
neither straight nor premul and doesn't fit color pipeline well.
- Straight alpha mode for render result was also eliminated.
- Conversion to correct alpha need to be done before linearizing
float buffer.
- TIFF will now load and save files with proper alpha mode setting
in file meta data header.
- Remove Use Alpha from texture mapping and replaced with image
datablock setting.
Behaves much more predictable and clear from code point of view
and solves possible regressions when non-premultiplied images were
used as textures with ignoring alpha channel.
for not finding it in review.
Also removed the hard limits on motion blur shutter time, soft limits are still
the same but it can be useful to set things lower/higher in some cases.
That change made all scrollwheel events be handled as if it was a swipe gesture.
Old style mouse wheel didn't work anymore.
This version should work for everyone, but we need more mac testers :)
scrolling and inertia.
Now Blender uses this - if you have 10.7. Otherwise it just falls back on the
old code.
Try it, makes a huge difference :)
Next todo: how to configure this well, so you can have trackpad (or mighty mouse)
zoom as default in 3d views.
Now:
- code is wrapped for OS X releases (10.6 and 10.7)
- It now detects scrollwheel (old mouse) and gesture strokes (mighty mouse or trackpad).
If you have 10.6, things will work as for release.
Next todo for tomorrow: make trackpad work actually smooth and not with steps.
Will also try to figure out the device type, to handle mighty mouse differently.
Patch [#33445] - Experimental Cycles Hair Rendering (CPU only)
This patch allows hair data to be exported to cycles and introduces a new line segment primitive to render with.
The UI appears under the particle tab and there is a new hair info node available.
It is only available under the experimental feature set and for cpu rendering.
Blender didn't detect properly whether event came from a mouse-wheel or
from a trackpad in OS X.
Now you can both, and both are handled independently.
Removed back hack from 2 years ago - which disabled mouse wheel for laptops.
remove it, but still stick around listed in the Window menu.
Fixed by removing the setReleasedWhenClosed:NO hack and using the proper cocoa
window delegate mechanism.
Mac OS X trackpad and 'mighty mouse' fix.
An old commit from Damien in 2010 tried to make mighty mouse touches work as if
this is a scrollwheel. The error in that code was that the "kinetic scrolling"
feature failed. When releasing your fingers, the events passed on to Blender
then switched from "trackpad pan" to "mousewheel zoom".
This commit makes trackpads and mighty mouse behave identical. Only difference
is that trackpad panning needs 2 fingers, mighty mouse only one.
Note that trackpad and mighty mouse 3d zoom works with holding ctrl!
All works nice with this kinetic feature now. Fun :)
a size parameter between 0.0 and 1.0 that gives a angle of reflection between
0° and 90°, and a smooth parameter that gives and angle over which a smooth
transition from full to no reflection happens.
These work with global illumination and do importance sampling of the area within
the angle. Note that unlike most other BSDF's these are not energy conserving in
general, in particular if their weight is 1.0 and size > 2/3 (or 60°) they will
add more energy in each bounce.

This implements AO baking directly from multi-resolution mesh with much
less memory overhead than regular baker.
Uses rays distribution implementation from Morten Mikkelsen, raycast
is based on RayObject also used by Blender Internal.
Works in single-thread yet, multi-threading would be implemented later.
not properly optimized out in some cases.
For reference, setting this will give detailed information about OSL shaders:
export OSL_OPTIONS="statistics:level=1,debug=1,llvm_debug=1"
(Error in 2.65 release too)
Mac OS X: on closing Blender, it 'flashed', which appeared to be a white window opening
and closing quickly. Caused by code trying to send focus to another opened window, and
accidentally focusing the closed one - causing it to reopen.
Nice formatted version (pictures soon):

Short list of main changes:
- Transparent region option (over main region), added code to blend in/out such panels.
- Min size window now 640 x 480
- Fixed DPI for ui - lots of cleanup and changes everywhere. Icon image need correct size still, layer-in-use icon needs remake.
- Macbook retina support, use command line --no-native-pixels to disable it
- Timeline Marker label was drawing wrong
- Trackpad and magic mouse: supports zoom (hold ctrl)
- Fix for splash position: removed ghost function and made window size update after creation immediate
- Fast undo buffer save now adds UI as well. Could be checked for regular file save even...
Quit.blend and temp file saving use this now.
- Dixed filename in window on reading quit.blend or temp saves, and they now add a warning in window title: "(Recovered)"
- New Userpref option "Keep Session" - this always saves quit.blend, and loads on start.
This allows keeping UI and data without actual saves, until you actually save.
When you load startup.blend and quit, it recognises the quit.blend as a startup (no file name in header)
- Added 3D view copy/paste buffers (selected objects). Shortcuts ctrl-c, ctrl-v (OSX, cmd-c, cmd-v).
Coded partial file saving for it. Could be used for other purposes. Todo: use OS clipboards.
- User preferences (themes, keymaps, user settings) now can be saved as a separate file.
Old option is called "Save Startup File" the new one "Save User Settings".
To visualise this difference, the 'save startup file' button has been removed from user preferences window. That option is available as CTRL+U and in File menu still.
- OSX: fixed bug that stopped giving mouse events outside window.
This also fixes "Continuous Grab" for OSX. (error since 2009)
* Simplify default color values, where each component was the same.
* Initialize closures as Null Closure, rather than assigning an existing closure, gets overwritten anyways.
This doesn't work nice currently and there's no simple workaround for this,
it'll require lots of statistics about cards and some further investigation
on supported combination of draw methods and multisamples supports.
For the release better be more stable and do not deliver dangerous option.
CMake had FFTW disabled by default, and when FFTW was not enabled it lead to
uninitialized memory usage. Now it falls back to wavelet if there is no FFTW,
and I've enabled it by default in CMake. If it's not found on Linux it will get
disabled automatically.
drop onto the application.
It seems something changed in the operating which makes our method of releasing
windows crash. Previously we called [m_window release], but on 10.8 this does
not remove the window from [NSApp orderedWindows] and perhaps other places,
leading to crashes. So instead we set setReleasedWhenClosed back to YES right
before closing, which will then do the cleanup for us.
Previously the OSL Mix shader node was clamping the 2nd color component (green) to the 3rd color component (blue). Now every component is clamped on its own.
operator< had wrong brackets, changed it now to be more clear.
Fix#33404: crash GPU rendering with OSL option still enabled. There was a check
to disable OSL in this case, but it shouldn't have modified scene->params because
this is used for comparison in scene->modified().
OSL noise() function is generating NaN's in certain cases, fix for that goes to our
OSL branch.
Also add missing minimum weight and max closure checks to OSL, forgot to add these
when fixing another bug.
Also some simple OSL optimization, passing thread data pointer directly instead
of via thread local storage, and creating ustrings for attribute lookup.
