Panda was adding a column with weights (0, 0, 0, 0), but these weights don't add up to 1 so no useful identity matrix can be produced. Instead it's better to fall back to the OpenGL default, (0, 0, 0, 1).
I'm also defaulting the transform_index values to (0, 1, 2, 3) to support non-indexed skinning (although that's pretty esoteric, given that that only supports 4 transforms...)
These parameters are already taken care of by set_state_and_transform().
Also comment out a few lines of code that would prevent the latter from being called for transform changes, but which never triggered anyway.
This is particularly the case when requesting a core-only profile (gl-version 3 2) where luminance textures are deprecated.
There is apparently no way to emulate them with swizzles (as we do with luminance textures), so we'll have to duplicate the channels out.
Fixes#693
These should be protected by an is_debug() check so that they can be optimized out properly in a release build. Setting check-debug-notify-protect in Config.prc can be used to track down cases of missed checks.
Officially, in core profile OpenGL 3.2+, calling it with a value higher than 1.0 is an error, but many vendors seem to let us. Apple's implementation does not. It appears that checking the maximum line width is a way to deal with this.
Fixes#466
Even a brief error message in the assertion is infinitely more useful to a user who is not at home in the source code, especially for assertions that may reasonably be triggered by honest user mistakes.
This is necessary for GLSL 1.30 which deprecates gl_FragData but does not yet support layout(location=) specifiers
Also fix some function pointer checks for pre-GL 3.0
Fixes#455
Previously, all draw calls would be grouped under "Primitive Setup", rather than under the appropriate bin collector. This commit fixes that and adds a few other useful collectors as well.
This changes includes so that local includes are consistently
#include "localFile.h"
while system and third-party includes are consistently
#include <systemFile.h>
This commit mostly converts the former to the latter; the two
exceptions are in android_main.cxx and fmodAudioSound.h, where
the reverse was necessary.
