I was looking through the shader files of the Dolphin Wii emulator, and came across these two shaders:
// Omega's 3D Stereoscopic filtering (Amber/Blue)
// TODO: Need depth info!
uniform samplerRECT samp0 : register(s0);
void main(out float4 ocol0 : COLOR0, in float2 uv0 : TEXCOORD0)
{
float4 c0 = texRECT(samp0, uv0).rgba; // Source Color
float sep = 5;
float red = c0.r;
float green = c0.g;
float blue = c0.b;
// Left Eye (Amber)
float4 c2 = texRECT(samp0, uv0 + float2(sep,0)).rgba;
float amber = (c2.r + c2.g) / 2;
red = max(c0.r, amber);
green = max(c0.g, amber);
// Right Eye (Blue)
float4 c1 = texRECT(samp0, uv0 + float2(-sep,0)).rgba;
blue = max(c0.b, c1.b);
ocol0 = float4(red, green, blue, c0.a);
}
And this one:
uniform samplerRECT samp0 : register(s0);
void main(out float4 ocol0 : COLOR0, in float2 uv0 : TEXCOORD0)
{
float4 c0 = texRECT(samp0, uv0).rgba;
float red = 0.0;
float blue = 0.0;
if (c0.r < 0.35 || c0.b > 0.5)
{
red = c0.g + c0.b;
}
else
{
red = c0.g + c0.b;
blue = c0.r + c0.b;
}
ocol0 = float4(red, 0.0, blue, 1.0);
}
Are these Open Shading Language? If yes, how can I use them in Blender? If not, how can they be translated?
