I only have some game experience but it’s common to need to perform some sort of viewport culling/sorting before you can send the data to OpenGL. As you may know you need to format the vertex, texture and color data into an array and generating that array can require signification calculations. In my isometric engine the sorting process got terribly complicated and CPU intensive, so much so in fact it won’t be able to run on mobile like I planned.
