Semi-automatic Shadow Volume Extrusion (2)
{"Image DocumentName": "Semi-automatic Shadow Volume Extrusion (2)", "Image ImageDescription": "Make two copies of every vertex, each with 4 components (x,y,z,w) v = (x,y,z,1) v\u2019 = (x,y,z,0) For a possible silhouette edge with vertices p & q. Assume light position L. Render a quad using vertices p, q, p\u2019, q\u2019 Vertex program computes pos = pos\uf0b4pos.w + (pos\uf0b4L.w - L\uf0b4pos.w)\uf0b4(1-pos.w) Straightforward to handle caps too.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
