well, I have no experience about how to develop 3d games but I want learn and create one. Also i did not know that there is many ways to create one. Thanks for the tip with creating simple 3d programs. I will sure try this to get more experience about developing such games.
But say, if i want to make nice 3D game, and I want to use Java as programing language, what programs do I need to manage developing the game? they should be all for free, since my finance is limited to buy any software.
