title: Find vertices in equilateral triangle mesh originating from a center vertex
body: <p>I'd like to ask whether there is code out there or if you can give me some help in writing some (C#, but I guess the maths is the same everywhere).</p>
  
  <p>I'd like to specify a center point from which an equilateral triangle mesh is created and get the vertex points of these triangles. The center point should not be a face center, but a vertex itself.
  A further input would be the size of the triangles (i.e side length) and a radius to which triangle vertices are generated.</p>
  
  <p>The reason behind it is that I want to create a mesh which is centered nicely on the screen/window center with as little code as possible. I just find mesh generation code, but not a "radial outward propagation" example.</p>
  
  <p>In the end, I'd like to have the subsequently farther away vertices being displaced in a logarithmic fashion, but I guess that's just an easy addition once the mesh code is there.</p>
  
  <p>Can anybody help me with that? Thanks!</p>
