WebTessellation shader: implement the level of detail directly in a shader Volumetric light: post-processing volumetric light using ray casting as in the GPU Gems 3 book How to build All of these examples have been tested on the following hardware: Intel HD graphics 620 Nvidia GeForce 940MX WebThis sample demonstrates how to render a procedural terrain using OpenGL tessellation shaders, including automatic level of detail and culling. It is not intended to show the optimal way of rendering terrain, but more to serve as a testbed for experimenting with tessellation shaders and different terrain heightfield functions.

WebQuad tessellation is similar to trianlges. The difference is that instead of barycentric coordinates gl_TessCoord.xyz which define point on a triangle (tcPosition) you have 2-component coordinate gl_TessCoord.xy (they also span in [0-1] range).. Hull shader (or Tessellation Control Shader in OpenGL terminology) looks pretty straightforward: WebFor triangles, each of the first three "outer" gl_TessLevelOuter [] tessellation values control the subdivision of one of the three sides of the triangle, and the fourth value is unused. …
