The demo below came from a technical challenge I set myself a few weekends ago. I often like to set myself small challenges like this… I guess it’s kind of like doing a cross word puzzle.
The challenge this week was to accurately simulate the movements of a car in 2D. Most people don’t realize this, but when a car turns it is rotating about a point outside itself, and that point is perpendicular to the wheels. It’s a little hard to explain, but if you check out the demo below then it all should become clear.
