Kevin Caccamo 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

Christoph Oelckers 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.

Christoph Oelckers 1768508c80 - first adjustments to decal code. 
- moved texture mode constants to a global header and consolidated with the variants of the 2D drawer.

Christoph Oelckers 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.

Magnus Norddahl 3b8b312fae - clamp the software light to never get brighter than the initial light level 2018-09-23 17:58:17 +02:00
Christoph Oelckers 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.

Christoph Oelckers 1967165633 - move view and projection matrices to DrawInfo. 2018-06-21 21:02:14 +02:00
Christoph Oelckers 4937848123 - refactoring of fixed colormap stuff to have it better organized and to reduce the number of uniforms in the main shader. 
This removes 3 uniforms, consisting of 9 floats. Those were merged into other values that never get used at the same time.
It also moves the costly setup of the fixed colormap out of the render state into the 2D processing code.
Since 3D forces use of render buffers now, it is no longer necessary to draw the entire scene with the colormap active, meaning it can be handled more efficiently.
 2018-06-16 22:40:44 +02:00
Christoph Oelckers 612fb40f3a - don't use uniforms related to fixed colormaps for other things. 
The fixed colormap is a per-scene global setting that normally does not need to change ever during rendering of a scene so it's easily shoved aside into a static uniform buffer.
Having to change this buffer for inconsequential stuff should be avoided, especially when there's other uniforms that are just as good to hold these values.

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

Christoph Oelckers d2dea17e81 - specify vertex attributes in the shader source for Vulkan compatibility. 2018-06-13 08:40:04 +02:00
Christoph Oelckers 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.
