Computing Anisotropic Lighting • Compute and propagate the normal, light vectors for both lights and the view vector (vertex shader) • In the pixel shader, compute contribution of each light <strong>using</strong> the light vector and direction of anisotropy • Adjust for self shadowing Light 1: Light 2: + = Game Developer Conference, San Jose, CA, March 7 th 2003
Computing Anisotropic Lighting: Vertex Shader Compute In the vertex shader, propagate the normal vector Compute light direction camera vectors position for and both the contributing view vector lights to pixel shader … // Output the normal vector ( w component contains ambient factor) o.Normal = float4( inNormal * .5 + (float3).5, fAmbient ); // Compute camera position: float4 vCameraPosition = mul( inv_view_matrix, float4(0,0,0,1) ); // Calculate view vector: o.View = normalize( vCameraPosition - mul( mWorld, inPos ) ); // Compute light direction vectors: light1Position = mul( inv_view_matrix, light1Position ); light2Position = mul( inv_view_matrix, light2Position ); o.Light1 = normalize (light1Position - inPos ); o.Light2 = normalize (light2Position - inPos ); Game Developer Conference, San Jose, CA, March 7 th 2003
