- g_sourceTexture

texture(platform-specific)Description
The texture to sample. - g_sampler
-
g_samplerType
sampler(platform-specific, does not exist on some platforms)Description
The sampler to use to sample g_sourceTexture.
Uniform Buffer Values
- g_blurStrength
-
float g_blurStrengthType
floatDescription
This is the strength of the blur - 0.0will leave the output texture unchanged from the input,1.0will do a full 3-texel average, and-1will do a full sharpen. - g_stepSize
-
float g_stepSizeType
floatDescription
The step between each sample, in texels. Usually scaled to be relative to the original input, which may have had a different resolution than our input texture due to the NTSC generation/decode process (if there's no original input, i.e. we're not using the NTSC signal generator and have gotten a signal straight from a real NTSC signal, then you'd just want to pick some nice-on-average value instead, possibly the width of the colorburst).
