- use the exact sRGB->linear transfer function in HDR mode as the 2.2 gamma approximation is visibly inaccurate in this case

- prevent excessively bright pixels as this is actually visible on a HDR monitor

- 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

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

- 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.

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

- 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

- 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

- added a vid_saturation control - works in postprocessing, only.

Quick fix: prevents negative values being passed to pow.

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.

Make sure we never pass a negative value to pow, and optimize gamma uniform

Added patch shader support to FShaderProgram
Added OpenGL 2 fallback support to render buffers
