Without using a pre-built physics engine, how can I implement 3-D collision detection from scratch?
- by Andy Harglesis
I want to tackle some basic 3-D collision detection and was wondering how engines handle this and give you a pretty interface and make it so easy ... I want to do it all myself, however.
2-D collision detection is extremely simple and can be done multiple ways that even beginner programmers could think up:
1.When the pixels touch;
