Magnus Norddahl	216191c86d	- interpolate the normal for models	2018-11-20 13:41:27 +01:00
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.	2018-11-11 16:04:36 +01:00
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.	2018-10-21 08:14:48 +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.	2018-09-29 13:23:40 +02:00

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.	2018-06-14 21:28:03 +02:00
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.	2018-06-13 17:44:49 +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.	2018-06-12 23:52:33 +02:00

Christoph Oelckers	3dc6ddbcc3	- check light direction in the shader. ... There are situations where lights on the wrong side of a linedef may be passed and those need to be skipped in the shader code.	2018-05-19 19:20:45 +02:00
