Implement instancing for repeated models #10

Closed jajkor closed 1 month ago

jajkor commented 1 month ago

OpenGL ES 3.0 added support for instanced rendering where many models of equal mesh data are drawn in a single draw call. Could be used for the campus map outline or the navigation path if we use a line of cubes.

Instancing was scrapped in favor of using geometry shaders to produce a continuous line for navigation. Will have to switch from OpenGL ES 3.0 to 3.2 as that version of the specification was the first to include them.
