- spelling - turns out we had tessellation spelt wrong all over.
- use \directive for doxy (not @directive)
- remove BLI_sparsemap.h - was from bmesh merge IIRC but entire file commented and not used.
Disabled double-side lighting by default and changed areas which are using
double sided lighting to switch it off just after doing stuff which requires
double side.
This makes code a bit more simple to follow (no all that disabling double side
lighting all over the code and so).
This change also fixes crash of blender caused by intel gme965 driver which
leads to stack corruption in some place when double side lighting isn't
disabled (probably driver still kind of using double side in some areas or so).
Hopefully it'll also fix#30293: Converting Text to Mesh
Thanks to Campbell to assist writing this patch!
support in some older cards, now it does a more precise check for problematic
cards so that it can be enabled on new cards that do support it properly.
- use more logical names for strings, noticed too many strings called `str` when reviewing name patch.
- pass __func__ macro to uiBeginBlock(), quite a few names were wrong (copy/paste error).
"The Blender Foundation also sells licenses for use in proprietary software under the Blender Licens"
also remove NaN references from files that have been added since blender went opensource.
shader = gpu.export_shader(scene,material)
Returns the GLSL shader that blender generates to produce the visual effect
of material in scene for the purpose of reusing the shader in an external engine.
This function is meant to be used in a material exporter so that the GLSL
shader can be exported entirely. The return value is a dictionary containing the
shader source code and all associated data.
The full documentation is under sphinx.
Warning: there has been an API between the patch and this commit:
uniform['lamp'] and uniform['image'] now return python reference to
ID block instead of ID name as before. The X3D exporter that uses this
function must be adapted.
we cant ensure that a requested buffer can be allocated so report opengl errors when failing to allocate the buffer (rather then printing to console).
this is common enough and generic error isn't too helpful to users.
- fix mistake with grease pencil UI (&& was intended but & used).
- use (void) rather then () across _all_ blenders code.
- a few minor edits, don't shadow stack variables in roll calculation & avoid running memset() for VBO vertex map.
OpenGL viewport render gave squeezed results in cases.
Reason: some graphics cards only give offscreen buffers in multiples
of 256 or 512 (my case).
Current fix uses the actual size returned by graphics card, which
is also safe for too large renders.
More elaborate cropping or matching is for another time.
(Added printf for feedback on this, might disappear)
Here is a image of it in action:

What it monitors:
* VRAM used by textures created via bf_gpu and BL_Textures
What it does not monitor:
* VRAM used by the Blender ui
* VRAM used by 2d filters
* VRAM allocated by the user via KX_Scene.pre_draw and KX_Scene.pre_draw
reported on launchpad.
calling glClear(GL_COLOR_BUFFER_BIT); was crashing blender,
since this is only used to blank the window before its drawn, disable for opensource ATI drivers.
Note, this is not like GE ffmpg, but Blender Image Texture
display for GLSL materials. Speed can be disappointing,
use smaller images for realtime edits.
set the draw method to triple buffer or overlap depending on the
configuration. Ideally I could get all cases working well with triple
buffer but it's hard in practice. At the moment there are two cases
that use overlap instead:
* opensource ATI drives on linux
* windows software renderer
Also added a utility function to check GPU device/os/driver.
