They both operate on a new type of primitive: GL_PATCHES. A patch is just a list of vertices which preserves their order of specification. They will give errors if patches are not passed to them. 8.1.1. Tessellation Control Shader ¶ They do the following:

Will not run outside of OS X without … The main task of the control shader, as stated above, is to determine how much tessellation to do. How that is done specifically is a multistep process. The three steps are the following: 1. Specify the number of vertices per patch 2. Perform any transformations to each vertex of the patch 3. Specify the … Ver mais The Geometry Shader sits after the Vertex Shader and before the clipping & culling stage of the pipeline. However, between the Vertex and … Ver mais The Tessellation Primitive Generator is responsible for doing the actual tessellation of the patch and generating each intermediate point. There is no specific shader code … Ver mais The Tessellation Evaluation Shader has a relatively simple job after the above steps have been completed - to specify the (x, y, z)location of the generated intermediate point.
