Hi community!
We all know this example of wireframe: three.js examples
It uses a custom attribute center, that contains repetitive data for vertices of each face, like this:
...
1, 0, 0,
0, 1, 0,
0, 0, 1,
...
My thought was: to have precomputed values is good, but can we make the same thing in vertex shader?
I tried this:
vCenter = vec3(0);
vCenter[int(mod(float(gl_VertexID), 3.))] = 1.;
And it worked.
The result of experiment is here:
