Anisotropic Metal Shader • Simulates properties of anisotropic surfaces – Brushed metal surfaces (brass, silver, etc.) – CDs (iridescence component would be added) • Models light scattering due to elongated features of brushed metal surfaces – Based on Heidrich / Seidel approach for computing anisotropic lighting • Underlying material is modeled as a solid volume of metallic rings – Similar to modeling procedural wood Game Developer Conference, San Jose, CA, March 7 th 2003
RenderMonkey Anisotropic Metal Example • Parameters allow tweaking the look of brushed metal for the effect – Ring volume center, direction and scale • Control the direction and placement of ring “trunk” volume and size of the rings – 2 lights: positions and color • For anisotropic lighting computation – Ambient lighting color and contribution coefficient – Ring color – Material ambient color • Workspace: – HLSL_Anisotropic.xml Game Developer Conference, San Jose, CA, March 7 th 2003
