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

99c8ba1288 - use uAddColor instead of uObjectColor2 for the ending color of a special colormap range. 
Unlike uObjectColor2, this is more global state. uObjectColor2 is part of gradient calculation which may later be offloaded to a secondary buffer which already resulted in only conditionally setting it, resulting in broken special colormap application for the software renderer.

f10ded756e - split shadowmap AABB tree into two parts. one for static and one for dynamic 
- upload only the dynamic AABB subtree using glBufferSubData
- change internal raytracing stack limit from 16 to 32
- update shadowmap AABB tree after R_SetupFrame for proper frame interpolation

9622ca7517 Add additive color before applying object colors 
Based on what I saw in this video (https://youtu.be/Yx1tflavea8), the 
additive colors are applied before the object colors

f2dcff4386 - more options for Doom 64 style gradients on walls: 
* Colors can npw be defined per sidedef, not only per sector.
* Gradients can be selectively disabled or vertically flipped per wall tier.
* Gradients can be clamped to their respective tier, i.e top and bottom of the tier, not the front sector defines where it starts.

The per-wall colors are implemented for hardware and softpoly renderer only, but not for the classic software renderer, because its code is far too scattered to do this efficiently.

3d81be1517 - always enforce a minimum distance for fog when fogmode is set to standard. without this, it was possible for the GPU to error out and stop rendering pixels for certain screen blocks 2018-10-09 04:45:23 -04:00

797f88a6c8 - some tweaking of shadowmap filter setting to allow changing the PCF filter's number of samplings. 2018-10-03 13:45:54 +02:00
Christoph Oelckers
c8852b8fea - enabled the linear shadowmap filter. 
Although this doesn't look as good as the PCF version it is a lot less calculation intensive and therefore more suitable for weaker hardware.
It also tends to bleed through walls a lot less.

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.
