Learning Compute Shaders : Painting with Compute Shader
Got it to paint at mouse position! Tested some effects like simple blur (take neighbor cell colors), fade (multiply by 0.9f), scroll down (take y-1 position)

00:00 setup project and scene
04:56 create script to execute compute shader and blit results on screen
12:35 move script into Camera, otherwise OnRenderImage wont get called
13:40 first results, from default compute shader
13:55 start playing with compute shader code
26:18 test setting pixels to random colors
33:40 test sending mouse position to compute shader
40:19 check what coordinates compute shader id.xy has
41:27 got mouse position working
49:20 add drawing color support
1:01:07 add scrolling texture
1:02:30 add fading out
1:04:31 add expanding
1:09:32 add blurring
1:11:11 test random stuff at the end
