mudlord 915132eb93 Added 2 more example raymarch shaders. 2016-07-29 16:10:55 +10:00
mudlord 72aee76479 Ported a tunnel shader that describes how to render a tunnel procedurally. 2016-07-29 15:04:42 +10:00
mudlord 9a81f4db05 Heh. 2016-07-29 13:26:31 +10:00
mudlord 35227f6dff Added some proof of concept procedural graphics shaders. 
These do not postprocess per se, but render entirely new graphics.
This is purely an abuse of the postprocess system. Would be ideal
with async compute, but what the hell :D

Arzed Five 7ee14b1c5a Create/change preset files in 'crt' and move the respective 
shader files to 'crt/shaders'
 2016-07-25 18:39:04 +01:00
Arzed Five 0593d28e8b (crt-easymode) The chromatic aberration bug should be gone now. There 
might still be lingering bugs due to filter_lanczos() addressing
elements of a matrix which hasn't been transposed.

Arzed Five 70d30ead4b A couple of MAD optimizations, some formatting and ensure the shader 
works a little bit better.
If the blending_mode macro on gb-pass1 is set to 0, we'll get only the
green background color.

Optimize a bit more. There is still some chromatic aberration going on: R, G and B are slightly offset from each other horizontally on my screen.

Final image doesn't seem to be quite right - horizontal lines are bumpy.
 2016-07-19 18:04:16 +01:00
rz5 a0608ed481 Update aann.slang 
Notable changes:
* As per https://www.opengl.org/wiki/GLSL_Optimizations, I tried replacing divisions with multiplications.
* All the color space conversion functions accept (and work on) vectors instead of single.

This part is subjective, but I formatted the code all around based on my idea of what looks most legible  .

@wareya, @Monroe88: Hi, could you both take a quick glance at my multiply-add optimizations? The wiki says it would make it faster, dunno by how much but it was easy to change and it didn't hinder legibility too much.

Update crt-geom.slang
 2016-07-18 13:18:57 -05:00
rz5 b4a3d72ca5 Update crt-geom.slang 
CURVATURE is now working. The problem was due to the replacement of ´´´IN.video_size / IN.texture_size´´´ (a small number representing the scale between the two sizes) with ´´´global.SourceSize.xy ´´´ (much bigger than the previous number).

SHARPER was made to work too.

@hizzlekizzle: I deleted your vec2 angle variable, which was hardcoded to (0, 0) while I was trying to fix the curvature stuff. Feel free to revert that.
