• Chinpokomon Rotation matrix: absolute rotation instead of relative?

  Hi, When multiplying rotation matrices for rotating around x, y and z-axes R = Rx * Ry * Rz ( http://en.wikipedia.org/wiki/Rotation_matrix ), I get a relative rotation matrix, meaning that rotation around Y is not the original Y-axis, but the new axis that has "occured" after rotating around X. What I want to do, is to have absolute rotation, so that the Y-rotation is performed around the original Y-axis, and not the new one (abs ...Show All

• Shon basic rendering problem with scene mesh

  Hi, I am rendering my scene mesh finally thanks to two very helpful replies from this forum! :] Everything renders basically ok, but where the walls of my scene mesh's "buildings" meet the "ground", there are these waving rows of little triangles that don't render on the bottom edges of the walls. If I move the camera, these triangles move with it, and sometimes something renders through a wall really briefly."Park be ...Show All

• EricZhong Game Engine - GUNS - adding particles

  Hello guys, I'm facing a problem in developing my GameEngine(in DirectX 9) for 3d space shooting game. Atm, I can fire with one type of gun - particle gun that spread one particle at a time.

  Hi every one. Does anyone know how to create an 8 bit raw file from a bitmap The idea is to generate landscapes from those raw files and also to automatically generate the raw and then create the terrain. Thanks in advance. Cubaconn Instead of completely RAW format, I'd advise using the PGM format (or PPM if you need RGB rather than just an 8 bit value). You can find details of the PGM format at: http://w ...Show All
