+#X text 283 34 This shader pipeline performs tessellation on a triangle primitive. Here's how it works: \; \; - The vertex shader (09.tessellation.vert) passes the original triangle vertices without modification. \; - The tessellation control shader (09.tessellation.tesc) sets up tessellation levels (5.0 for inner and outer edges) and passes vertex data to the tessellation evaluation shader. \; - The tessellation evaluation shader (09.tessellation.tese) subdivides the triangle into smaller triangles based on the tessellation levels and interpolates positions and normals for each new vertex. It also calculates pseudo random colors for each new vertex using cosine functions based on position. \; - Finally \, the fragment shader (09.tessellation.frag) renders each fragment with the color computed during tessellation. \; \; The result is a single triangle subdivided into many smaller triangles with a procedural color pattern that creates a visual effect with color variations based on position., f 94;
