787638ff5f - 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

58b7967eea - 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.
(refactored patch by Graf)

1b7312c0d0 Revert "- check light direction in the shader." 
This reverts commit e9f7383279.

It was not needed in the old version.

b3da533033 - fixed precision issue with dot product. 
Apparently the shader math is not precise enough to ensure that two supposedly orthogonal vectors are truly orthogonal, resulting in a non-zero dot product

(cherry picked from commit cce6c9a085)

e9f7383279 - 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.

d586d774cf - adjusted GL renderer to the new rules for alpha textures. This means that the translation fallback is only needed for the legacy renderer now. Modern GL can use the regular texture and will apply a grayscale mapping instead of merely using the red channel. 2018-03-22 20:42:17 +01:00

769867475c - Replaced max(dot(a,b), 0.0) with clamp as some rounding errors caused pow to receive negative values when then value was subtracted from 1.0 (undefined glsl behavior) 
- Fixed that surface angle attenuation was getting applied twice

b4915d624d - 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
