Graphics Town Gallery Our class made some really cool towns! This shows screenshots from some of them. We gave each of the different projects a label (apologies to the creators). Flame Land A flame moves as it walks randomly, helicopters swoop,… what more could you ask? Check out the shadows and bump maps. Atlantis Atlantis world rises from the sea at startup. Lanterns Land A person with a lantern walks in the night (and day), a particle system water fountain which falls with gravity (and slides on the fountain surface with some friction), lighting shaders on windows.
