Christoph Oelckers	8b6e09ca09	- changed the license of the OpenGL renderer to LGPL v3. ... This was done to clean up the license and to ensure that any commercial fork of the engine has to obey the far stricter requirements concerning source distribution. The old license was compatible with GPLv2 whereas combining GPLv2 and LGPLv3 force a license upgrade to GPLv3. The license of code that originates from ZDoomGL has not been changed.	2016-09-14 20:01:13 +02:00
Christoph Oelckers	2b92048a5b	- renamed the texture coord variables in GLWall. ... It makes no sense having them organized differently in this struct than what the rendering code needs. This saves one redundant copy operation and a function-local static variable.	2016-05-05 11:48:39 +02:00
Christoph Oelckers	5a2eac8f15	- floatified vertices and removed the now redundant fx and fy members. This needs an added check for polyobject origins, though, so that such subsectors don't get rendered.	2016-04-03 11:40:14 +02:00
Christoph Oelckers	3644073bbd	- use a software buffer for immediate mode rendering. This allows using the regular buffer code to collect data for both render modes and allows removal of a lot of duplicated code.	2014-06-15 01:14:41 +02:00
Christoph Oelckers	c39318f406	- use vertex buffer and reuse of data for stencil drawing. A stencil needs to be drawn multiple times with the same polygons so this is a good place to optimize.	2014-05-31 09:32:17 +02:00
Christoph Oelckers	f7404d20fb	- add vertex buffer based drawing for all walls and flats.	2014-05-11 01:23:27 +02:00
Christoph Oelckers	b09405a8bd	- changed rendering of glowing walls so that it doesn't require an additional vertex attribute, just pass the floor and ceiling planes as uniforms.	2014-05-10 17:09:43 +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
