Adding Textures

To add textures, use the hierarchical nature of the file format and add an optional TextureFilename data object to the Material data objects. The Material objects now read as follows:

Material RedMaterial {
1.000000;0.000000;0.000000;1.000000;;    // R = 1.0, G = 0.0, B = 0.0
0.000000;
0.000000;0.000000;0.000000;;
0.000000;0.000000;0.000000;;
TextureFilename { "tex1.ppm"; }
}

Material GreenMaterial {
0.000000;1.000000;0.000000;1.000000;;     // R = 0.0, G = 1.0, B = 0.0
0.000000;
0.000000;0.000000;0.000000;;
0.000000;0.000000;0.000000;;
TextureFilename { "win95.ppm"; }
}
