I have been concentrating on the car physics side..
That and collision detection..
Did a hell of a lot of reading on 3d coding on wikipedia, but I think I understand the basics for a 3d engine now.
Also I think I could pass an A level physics exam as well..
I have messed about with opengl...
I was thinking of starting on a hard drivin clone some time next month..
I haven't tried any console dev'ing before, but I am going to need some help with car models and track obects.
All flat shaded, no texture sort of affair.
It is a long way off , but just wondering if you would like to...
