Uses GLSL for drawing image in Image Editor space.
This requires change in image_buffer_rect_update, so
original float buffer is being updated as well. This
is unlikely be something bad, but will keep an eye
on this change.
Also no byte buffer allocation happens there, this
is so because byte buffer used for display only
and in case of GLSL display such allocation and
partial update is just waste of time.
Also switched OpenGL render from using CPU color
space linearization to GLSL color space transform.
Makes OpenGL rendering pretty much faster (but
still slower than in 2.60).
internal changes:
- Added functions to setup GLSL shader for color
space conversion in colormanagement.c. Currently
conversion form a colorspace defined by a role to
linear space is implemented. Easy to extend to
other cases.
- Added helper functions to glutil.c which does
smarter image buffer draw (calling all needed OCIO
stuff, editors now could draw image buffer with a
single function call -- all the checks are done in
glutil.c).
- Also added helper function for buffer linearization
from a given role to glutil.c. Everyone now able to
linearize buffer with a single call.
This function will do nothing is GLSL routines fails
or not supported.
And one last this: this function uses offscreen
drawing, could potentially give issues on some
cards, also will keep an eye on this.
The Scopes and Histogram (Image editor, Sequencer) were not updating on
changes in color or display settings.
- Missing notifiers for refreshing
- Missing code to draw correct for managed byte buffers.
Historically, F shortcut was for 'add edge/face' in Blender.
In Node editor, F makes a noodle, ctrl+f made a noodle replace too.
To keep ALT+F work for "Unattach from frame", the solution I now propose
is to make CTRL+F for finding nodes, and SHIFT+F for 'add noodle with replace'.
Added a sanity check to the ED_node_link_insert function to ensure it exits gracefully if no suitable sockets can be found. This was the problem with custom pynodes, which don't define the 'type' DNA of old sockets. The operator will have to be generalized for future nodes, but for now just not crashing seems good enough.
Script node crashes in #34810 were caused by uninitialized 'type' integer as well. This is now done in the set_typeinfo function for sockets (like for trees and nodes too), to avoid any potential remaining issues of this kind. Note that new files need to be loaded and saved again once to be forward compatible again.
well as I would like, but it works, just add a subsurface scattering node and
you can use it like any other BSDF.
It is using fully raytraced sampling compatible with progressive rendering
and other more advanced rendering algorithms we might used in the future, and
it uses no extra memory so it's suitable for complex scenes.
Disadvantage is that it can be quite noisy and slow. Two limitations that will
be solved are that it does not work with bump mapping yet, and that the falloff
function used is a simple cubic function, it's not using the real BSSRDF
falloff function yet.
The node has a color input, along with a scattering radius for each RGB color
channel along with an overall scale factor for the radii.
There is also no GPU support yet, will test if I can get that working later.

New operator "Find Node".
Opens search menu, and allows to find a node based on name or label.
On selecting name, menu selects/activates the node and moves the view to it.
Shortcut: ALT+F
Menu: Node editor, "Select"
Apparently C== allowed to have implementations of
OCIOImpl::setupGLSLDraw, OCIOImpl::finishGLSLDraw and
OCIOImpl::freeGLState in two different files.
STUPID!
This reverts rev55642 and fixes issue in a different way.
The thing here is: isolated vertices are for sure not in BVH
and updating keyblock could not only rely on idea that all
vertices are in BVH (no idea why it was noticed just now).
Solved in a way, that uses old keyblock coordinates as new
keyblock, and then refines it using coordinates from BVH.
Hopefully it'll cover all cases now :)
* Add a poll function that only activates the operator when a stencil
brush is active
* Change shortcuts to RMouse - translate, Shift - RMouse Scale, Ctrl -
RMouse, rotate. MUCH faster and simpler workflow.
* Change shortcut of colour sampling to S. Sampling is important but not
as important as warranting the Right Mouse button.
* Add a notifier so that toolbar gets updated texture rotation when
rotating the stencil
Also,
* Slight rearrangement of options so that jittering is more accessible
(easily more often used than smooth stroke)
* Using masking is determined only by the presence of the texture,
remove extraneous DNA flag (might cause issues later but in practice
brush options are not harmful)
* Overlay and angle sliders are active during stencil mapped brushes
* Only draw the overlay if there's a texture.
* Unnecessary shader inputs inside the Mix Shader are now ignored, in case the factor is 0.0 / 1.0 and not connected.
This way we save some render time for complex node graphs.
Example: http://www.pasteall.org/pic/show.php?id=48226
Check the Mix Shader at the end: In this case, Cycles will now avoid the complete huge shader tree, and only calculate the Diffuse Shader.
Rendertime decreased from 1:50 min to 1:20 min on CPU. GPU rendering benefits as well from this.
This only affects SVM, OSL was already doing these optimizations.
Stencil style texture mapping. Ready for field testing and user feedback.
This commit adds stencil like brushes, like those that existed on old ptex branch.
(with the exception of clip colour)
To control the position of the stencil, you use
Q: translation
Shift - Q: scaling
Ctrl - Q: rotation
There's extra work that has been done to make this work:
* Support for coloured overlay in vertex/texture painting
* Also made A button do stroke mode selection like in sculpt mode,
when mask painting is inactive.
There are some TODOs to work on during bcon3:
* Support tiled and stencil mode in 2D painting. Support alpha textures also.
* Tidy up overlay code. There's some confusion there due
to the way we use the primary brush texture sometimes for alpha, other times
for colour control.
WIP design docs will be in
http://wiki.blender.org/index.php/User:Psy-Fi/New_Brush_Tool_Design
sculptification commit. We have a drop menu to select the stroke mode
now. Jitter controls appear under stroke panel under all modes (As they
should! They stroke control options). Also enable jittering for all
modes. I really fail to see why not.
