Opengl draw mesh
WebOur project is an attempt in the implementation of the first phase of Hugues Hoppe’s PhD thesis. The publication lays out a generalized approach to the generation of a piecewise linear surface, consisting of triangular faces pasted together along their edges, from a set of unstructured points that are assumed to lie on or near an unknown surface.

And this is how you do that in OpenGL: In the vertex shader, you supply vertex position and normal as you usually do, but now you also have a vertex attribute for the transformation like this: in mediump vec4 position; in mediump vec4 surfacenormal; in mediump mat4 trf;
Web3 de mai. de 2024 · To get good performance, groups of voxels are assembled together into a single mesh, called a "Chunk". A chunk is typically something like 16x16x16 voxels, but might be larger or smaller as you need. It contains only the visible faces of voxels in that chunk, stitched together into a single mesh that can be drawn with a single draw call.
