Christoph Oelckers	7d3beb665b	- rewrote vertex buffer code to require GL_ARB_BUFFER_STORAGE extension. ... This means it won't work anymore on anything that doesn't support OpenGL 4.0, but I don't think this is a problem. On older NVidia cards performance gains could not be seen and on older AMDs using the vertex buffer was even worse as long as it got mixed with immediate mode rendering.	2014-05-10 21:47:07 +02:00
Christoph Oelckers	69af73d9b9	- alternative configuration using GLEW to get extension functions. This requires GL 2.0, though so it won't be promoted to the mainline for the time being. ... - removed all pre GL 2.0 support.	2014-04-06 14:35:44 +02:00
Christoph Oelckers	5f08111a34	- fixed: The GL voxel palette loader needs to handle the case when the voxel has no own palette and used the game's base palette instead. Also added an implementation for GetPixels because this is used when a voxel needs a translated palette.	2013-09-28 23:33:55 +02:00
Christoph Oelckers	2885056f46	- moved GLEXT API out of RenderContext struct.	2013-09-03 18:29:39 +02:00
Christoph Oelckers	26943fe3fd	- removed gl interface function pointers for all OpenGL32.dll entry points.	2013-09-03 14:05:41 +02:00
Christoph Oelckers	399d0974ab	- added GL render as of SVN revision 1600.	2013-06-23 09:49:34 +02:00
