da806b354d - cleanup of the revised y-clamping feature. 
This integrates better with the existing features.

918e9e9b0d - fixed texture clamping for elements that are partially behind a slope. 
This is mainly mid textures on linedefs and decals.

c7db3875e1 - fixed: colors from brightmaps and glowmaps need to be desaturated. 2021-09-14 19:49:41 +02:00

e1a5f61f8c - fixed: shaders with NO_LAYERS defined may not apply brightmap and glowmap. 
These are undefined for such fragments.

39513cf7ae Revert "- eliminate an unexpected slow path in the fragment shader." 
This reverts commit cd5aa65fda.

This does not work as expected, needs more investigation.

cd5aa65fda - eliminate an unexpected slow path in the fragment shader. 
Apparently with checking uLightLevel the shader cannot discard the slow software lighting path entirely adding a significant amount of processing time.
Changed to check the actual lightmode value, which re-enables the fast path again.

b20de184a0 - made the new Build light mode operational 2020-06-11 08:48:33 +02:00
Christoph Oelckers
5896f24eba - added a new light mode that emulates Build's depth fading. 
Not active yet, this needs some testing and finetuning.

9e51a2f63c - added Build's NPOT emulation to the backend. 
For GZDoom this is completely disabled, of course, because the Doom engine does not need it, but in order to have the same backend code in both engines it needs to be present.

7c46dace03 - this still doesn't work on Vulkan. :( 2020-04-19 10:57:44 +02:00

8381092cce - major shader rework 
* handle brightmaps in the main shader instead of keeping separate instances around.
* added detail and glow layers from Raze.
* fixed material setup which could not guarantee that everything was initialized correctly.
* for warped textures, warp all layers. With this brightmaps finally work on warped textures.

Note: Vulkan reports a "device lost" error with this which still needs to be investigated.

738b9ceb08 - fixed incompletely changed shader. 
It was still using a variable from the first revision that no longer exists.

bb8db9422f - scaled down the texture colorization feature for easier usability. 
It makes little sense exposing every minute detail of this through UDMF.
Setting it up that way is far too complicated. Using virtual textures that map to a real texture plus a colorization record should be far easier to use by mappers.
This also doesn't piggyback on the Doom64 color feature anymore and is completely separate, despite some redundancies.
This is still missing the texture definition part, though.

3209d4ed23 - added a few more texture coloring options to the shader. 
Aside from adding an additive component it can now also do:

- desaturation (not limited to the range of 0..1 so it can also be used for oversaturation by applying a negative number or negative saturation by going above 1.0.
- invert the texture
- apply a blend, including 3 special mode taken from EDuke32.

Currently only the implementation is done, it is not exposed to UDMF yet.

da2d0e47e6 - removed array length() function from shadowmap shader 
Array's length() function is not yet supported by SPIRV-cross and MoltenVK
Its usage was replaced by explicit nodes count value passed as uniform

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.

additive colors are applied before the object colors
