ColorBlindnessPostProcessor

PostProcessors can be used to apply a shader to the entire screen. It is recommended you use the [[ScreenShader]] to build your post processor shader.

The screen texture comes through as this uniform

uniform sampler2D u_image

Post processor shaders get some default uniforms passed to them

uniform float u_time_ms - total playback time in milliseconds uniform float u_elapsed_ms - the elapsed time from the last frame in milliseconds uniform vec2 u_resolution - the resolution of the canvas (in pixels)

Custom uniforms can be updated in the [[PostProcessor.onUpdate]]
