Christoph Oelckers	ae1e090716	- all non-shader related GL calls are gone from the main code base.	2019-10-04 21:13:04 +02:00
Christoph Oelckers	f992aebf33	- two more	2019-10-04 19:17:55 +02:00
Christoph Oelckers	cb80e877ff	- refactored fog and depth func setting into GLInterface.	2019-10-04 18:44:16 +02:00
Christoph Oelckers	204abab724	glColor calls refactored.	2019-10-04 18:25:18 +02:00
Christoph Oelckers	96c0c3197c	- abstracted away more OpenGL calls, in particular all matrix access.	2019-10-04 18:12:03 +02:00
Christoph Oelckers	ad4527c8be	- initialize the GL backend in the proper place. ... As long as there are still video mode switches this needs to be in the video mode switching function.	2019-09-23 23:33:59 +02:00
Christoph Oelckers	e0f823a492	- refactored texture setup to use an intermediate layer.	2019-09-18 22:16:15 +02:00
Christoph Oelckers	d63cf04e06	- removed the compressed texture cache. ... This is a pointless relic from the past and makes zero sense with modern graphics hardware.	2019-09-17 20:18:18 +02:00
Christoph Oelckers	b1763a8f4a	- hooked up the texture management. ... Not in active use yet!	2019-09-17 19:03:42 +02:00
Christoph Oelckers	2b439ae181	- work on backend	2019-09-16 23:28:26 +02:00
Christoph Oelckers	9edf6be10d	- texture sampler class added, not used yet.	2019-09-16 22:56:48 +02:00
Christoph Oelckers	6536d910b3	- all drawing is being routed through the interface layer, all vertex buffers are gone. ... No big loss here, none of them made much sense performance wise.	2019-09-16 21:08:42 +02:00
Christoph Oelckers	318009fd69	- added a centralized drawer and converted the main geometry drawer to use it.	2019-09-16 19:35:04 +02:00
