3D Animation. Future City Traffic v0.2. Demo.
In this version I took a number of low poly people, added a variety of walk loops (which walk at different speeds), and replicated them at no additional memory cost.
The results are spectacular! Mass walking scenes. Now there is no collision detection, so probably if you look closely some "people" are walking through others, but the general effect holds - load of people walk to walk alongside a futuristic looking pair of traffic streams.
Success!
