Hi.

I've got a nice little program that displays .x files in fullscreen mode, with pretty lights and things. The idea is that I make a landscape in a 3D program, export to 3ds and then convert to .x. Then I want to be able to move around it freely.

Problem 1: I want to use a Quake style control, like with the mouse looking around. How do I set the viewport to be looking in a certain direction according to the mouse? Keyboard control (fwd, back, strafe) should just be movin viewport pos left and right, yeah?

Problem 2: How do you texture the 3d objects so the textures are in the right place?

Problem 3: I need a waterfall on the side of a hill (like a spring - very pretty huh?). How do I put the particle system in a certain place and scale it depending on how far away I am from it? Use x, y, z values in the class?

Please help!
