Some resources can't be shared across different rendering contexts while
others can. Additionally, the standard GLEW library does not support
multiple rendering contexts (that's what GLEX MX is for), even though it
might work on some (or even most) cards. WGL supports reuse of a
rendering context across multiple windows as long as the pixel formats
are the same.
The problem was caused by every window using an own OpenGL context and certain objects not being shared between those.
The best solution would still be to make all windows use ONE OpenGL context. But this would probably need a more or less large rewrite?
This solution has to be considered a workaround with basically no negative side-effects, as the loss of speed is most likely irrelevant in editor mode.
4x3 matrices use the same number of uniform components as 4x4 ones.
If we're short on uniform components, don't transpose the transformation
matrix before sending it to the shader, and transpose it in the shader
itself instead, saving 4 components per bone.
The last row of the bone transformation matrix always is 0,0,0,1 so
there's no point in uploading it. Also reducing the max bone count to 80
which means the uniform array will fit into the available space on 6000
and 7000 series Geforce GPUs.
Most of the permissive free software licenses look similar enough that
pointing out which one it is may be useful for people giving the file a
quick glance.
Adds text to local TODO.txt file. Useful for taking notes quickly e.g. when testing new scenarios in a network game.
TODO filenames are configurable. Default file is TODO.txt in the scenario file (if it's unpacked) and TODO.txt on the current path if access to the first location failed.
As long as we're not actually using a different shader for meshes
without bones, we need to upload an identity matrix so there's defined
data in the bone slot.
Doing skinning on the GPU shows a noticeable performance improvement in
pretty much any situation, but especially so in scenes with lots of
animated objects with high polygon counts.
Calling CStdGL::CheckGLError calls glGetError, which is really, really
slow because it has to flush the pipeline to check whether there's an
error or not. Plus it's not like we can do anything about it anyway. If
you want to be notified when an error happens, pass --debug-opengl to
the executable.
