Finally got my actual OpenGL ES VBO based grid renderer up n running last night. Next job is to write my 'GlyphBlt' routine before I start coding actual 'demo routines' - The fun part!
Learned a whole lot all ready, but at least now i'm in more comfortable territory of 'just' setting a pixel at a certain place to a certain colour.
I've realised with a 'fine' resolution parent grid for the glyphs the method i'm using isn't massively efficient when updating a lot of data (my test code has been doing 50%). I know a way around that - but I can improve that later if its really an issue which I don't think it will be for this demo.
This cold weather should help move things along! Don't think I'll get any days off work down here in Somerset though
