Web16 de nov. de 2024 · 1 Imagine I have a cube which consists of six surfaces. My goal I want to reach is to be able to export this cube in STL format. Tessellating a cube is quite easy but this is just an example here. Now I want to use the OpenGL tessellation shader to perform the tessellation and grab the created triangles and use them as STL triangles. Web29 de ago. de 2014 · The tessellation shader is for variable subdivision. An important part is adjacency information so you can do smoothing correctly and not wind up with gaps. You could do some limited subdivision with a geometry shader, but that's not really what its for. Geometry shaders operate per-primitive.
