dca0b75038 - change the images to be upside down until presentation to increase compatibility with shaders designed for OpenGL
- clamp scissors fully to avoid NVidia's awful drivers locking up the entire system if they end up out of bounds
- perform buffer clears as part of the render pass. this puts some restrictions on how FRenderState.Clear can be used
- add an offset uniform to the present shaders so the vulkan target can flip the image during presentation

7362070504 - add dithering to present shader 2018-08-07 03:03:40 +02:00

ce50b0e46b - read sampler bindings from the shader instead of tagging along a large amount of support data.
Works for most shaders, except SSAO.

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.

48f753061a - uniform buffers for the present and shadowmap shaders 2018-06-11 21:42:09 +02:00

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

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

63da6e70c0 - added a vid_saturation control - works in postprocessing, only. 2017-07-02 16:45:06 -04:00

2339b18b01 Quick fix: prevents negative values being passed to pow. 2016-09-22 09:23:26 +02:00

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

a8d1197ea7 Make sure we never pass a negative value to pow, and optimize gamma uniform 2016-08-16 00:01:18 +02:00
