hi, If anyone could give me a hand with any of these questions I'd be most greatful... 1. Lighting. I'm writing an isometric tile based game using D3D-IM; using TL vertices. Therefore I need to specify a colour for each vertex. I can write a reasonable lighting engine that'd colour a vertex based on it's distance from a [point] light source. What I want to implement is normal-based shading... Say I have a 3D point for a light, it's colour, range, attenuation etc. And I have a tile with 4 points defined in 3D space, How do I work out whether it is facing the light/not facing it and work out how much the lighting needs to be modified in order to be shaded correctly. Basically I'm trying to emulate the D3D lighting engine in a simple way 2. Binary file access; I've looked through the help file and gotten quite confused. Say I have this datatype Type TileData X as integer Y as integer Texture as string LightColour(3) as long End Type How could I use Binary access to read and write this 40,000 times (a 199x199 array)? -Done- Many thanks in advance; Jack,
