   Programmatically generate arena
  Hello,I need to write a function that creates a model of a tiled up circular arena. This arena will be tiled up much like a square grid, in that one texture will be used for every tile. I can't take advantage of texture repetition along u and v because I want to have control over the width/height definition of the tiles. Also, my little game doesn't use shaders and is written in OpenGL.Can someone give me some hints on how to go about doing this? A link to a tutorial/site would be very welcome!   
  If your tiles are on a 2D plane you can can use Bresenham's circle algorithm to find the edge of the arena, and then do a flood fill to place the inside tiles. Substitute tile for pixel when reading the descriptions for the algorithms.
