Translucent Iridescent Shader Algorithm: Basic Steps 1. Compute light, view and halfway vectors in tangent space 2. Load base texture map, gloss map, opacity map and normal map 3. Compute diffusely reflected light 4. Compute scattered illumination contribution 5. Adjust for transparency of wings 6. Compute iridescence contribution 7. Add gloss highlights 8. Assemble final color Game Developer Conference, San Jose, CA, March 7 th 2003
Translucent Iridescent Shader: Vertex Shader .. // Propagate input texture coordinates: Out.Tex = Tex; // Define tangent space matrix: float3x3 mTangentSpace; mTangentSpace[0] = Tangent; mTangentSpace[1] = Binormal; mTangentSpace[2] = Normal; // Compute the light vector (object space): float3 vLight = normalize( mul( inv_view_matrix, lightPos ) - Pos ); // Output light vector in tangent space: Out.Light = mul( mTangentSpace, vLight ); // Compute the view vector (object space): float3 vView = normalize( mul( inv_view_matrix, float4(0,0,0,1)) - Pos ); // Output view vector in tangent space: Out.View = mul( mTangentSpace, vView ); // Compute the half angle vector (in tangent space): Out.Half = mul( mTangentSpace, normalize( vView + vLight ) ); return Out; Compute Halfway vector Compute Define H tangent light = V vector + L space in matrix Compute tangent view space vector in tangent space in tangent space Game Developer Conference, San Jose, CA, March 7 th 2003
