This can be used for loading .ppm files or just data straight from the drive. the idea is that you turn on textures like states. Once a texture is loaded you can turn it on to affect anything that gets drawn. Most systems have 4-8 texture slots that can be activated and used as input for your shaders.
Textures can have data inputted into them from either a file, CPU memory, stripped off of the screen or written by a render/frame buffer.

| TextureType | tt | |||
| ) |
Setup the texture to behave as a dynamic texture. This is to be used when you write to it using the screen or a render/frame buffer.

Load the image from the drive in the format of a .ppm file.

| void Texture::ChangeFilter | ( | bool | bNearest | ) |
Switch between glNearest (1) or glNicest (0). You want to use Nearest for any data processing, and Nicest for anything that will be presented.
