Rachael Alexanderson	b4915d624d	- removed 'cooling' component of the shader since it technically wasn't really functional (guess we have to use a separate shader to do that) ... - changed the math to use the 'mix' formula	2017-07-02 16:59:15 -04:00
Rachael Alexanderson	0d8b7c55ef	- added a grayscale formula selector	2017-07-02 16:45:06 -04:00
Rachael Alexanderson	bd02893ce7	- expanded hard limits for saturation to -15.0/15.0 ... - added menu option for saturation - tried to get the new saturation shader to consume less GPU power by turning it off when it is 1.0	2017-07-02 16:45:06 -04:00
Rachael Alexanderson	63da6e70c0	- added a vid_saturation control - works in postprocessing, only.	2017-07-02 16:45:06 -04:00
raa-eruanna	2339b18b01	Quick fix: prevents negative values being passed to pow.	2016-09-22 09:23:26 +02:00
raa-eruanna	72491049e0	Changes to the contrast/brightness/gamma formula for both hardware and shader gamma correction. Mainly makes a correction with the shader version where contrast/brightness being negative values would clip them inappropriately.	2016-09-22 09:23:25 +02:00
Magnus Norddahl	a8d1197ea7	Make sure we never pass a negative value to pow, and optimize gamma uniform	2016-08-16 00:01:18 +02:00
Magnus Norddahl	5849c83028	Added bloom and tonemap to menus ... Added gl_renderbuffers CVAR that disables render buffers Added patch shader support to FShaderProgram Added OpenGL 2 fallback support to render buffers	2016-07-29 21:31:20 +02:00
Magnus Norddahl	aeb7df09de	Added hardware gamma option and improved window handling on Windows	2016-07-27 11:15:19 +02:00
