Magnus Norddahl	bab5862383	- fix some vulkan warnings	2019-05-13 21:15:10 +02:00
Magnus Norddahl	d4118a755c	- load all the shaders and use the right one for each renderpass	2019-03-01 02:40:02 +01:00
Christoph Oelckers	bc1e659c7b	Revert "- reworked fog uniforms to move the global fog mode setting to the viewpoint buffer." ... This reverts commit 8b26b6dd1e. This was causing problems with light mode 2 because some edge cases were no longer handled properly.	2018-09-16 22:38:20 +02:00
Christoph Oelckers	8b26b6dd1e	- reworked fog uniforms to move the global fog mode setting to the viewpoint buffer.	2018-09-06 19:14:30 +02:00
Christoph Oelckers	ad7aaa8f2a	- specify fragment output locations in the shader source. ... OpenGL has been supporting this since version 3.3 and Vulkan requires it so it's the way to go.	2018-06-12 23:52:33 +02:00
alexey.lysiuk	1fd37ff2ff	Removed unused input from fog boundary fragment program ... This should fix https://mantis.zdoom.org/view.php?id=151	2017-02-01 10:05:38 +02:00
Christoph Oelckers	eb9d2d9917	- reactivate compatibility profile so that immediate mode drawing can be used on older hardware not supporting persistently mapped buffers. ... - reactivate alpha testing per fixed function pipeline - use the 'modern' way to define clip planes (GL_CLIP_DISTANCE). This is far more portable than the old glClipPlane method and a lot more robust than checking this in the fragment shader.	2014-07-17 02:37:18 +02:00
Christoph Oelckers	6046b11b4f	- all shaders now compile in core profile.	2014-07-15 01:05:53 +02:00
Christoph Oelckers	00fcf4bc06	- for some reason using world coordinates for clipping in the shader is somewhat imprecise so the clip plane heights have to be adjusted a bit for it.	2014-07-13 13:25:42 +02:00
Christoph Oelckers	d868f60f6c	- since the clip planes for plane mirrors did not work anymore I reimplemented them using shader based logic. It still needs to be seen if this affects performance on older hardware.	2014-07-13 12:14:12 +02:00
Christoph Oelckers	4d005bdfa0	shader rework ... All those special shaders have been merged together. Mostly working but the non-shader lighting seems a bit broken.	2014-05-12 14:45:41 +02:00
Christoph Oelckers	09f4071436	Ok, it had to be done: Removed shader support for pre GLSL 1.3/GL 3.0 hardware. The compromises needed to accomodate these are just too bad and would block any attempt at streamlining the code.	2014-05-11 13:27:51 +02:00
Christoph Oelckers	e00847f64b	- GZDoom solution file ... - missing GL resources for gzdoom.pk3.	2013-06-23 11:13:01 +02:00
