hey knale, in reply to what you asked in my journal. The 1024 texture you're referring to is whats known as a 'heightmap.' You know when you're playing WoW or BF2 or games similar to that, and you're traversing through a world where the terrain around you looks really good? Yep, thats what mine is, although it is quite small.. And elaborating on what a frustum is: "In 3D computer graphics, the viewing frustum or view frustum is the region of space in the modeled world that may appear on the screen; it is the field of view of the notional camera. The exact shape of this region varies depending on what kind of camera lens is being simulated, but typically it is a frustum of a rectangular pyramid. The planes that cut the frustum perpendicular to the viewing direction are called the near plane and the far plane. Objects closer to the camera than the near plane or beyond the far plane are not drawn. Often, the far plane is placed infinitely far away from the camera so all objects within the frustum are drawn regardless of their distance from the camera." - (Wikipedia, 2007)
My game engine is going to be something like the "Torque" game engine. Google it if you want more info. But its mainly going to be related to 3d graphics for now, the rest will come later.
Hope that helps, the games industry is really competitive, when or if you get in Uni (or perhaps you already have) look for Uni's which support games or media development specific for the games industry. If they have it where I'm at in the world, I'm sure they'll have it where you are =] Good luck and keep improving!
