When porting your IRIS GL code, set this alpha component to 1.0, indicating 100 percent opaque. The alpha values are then determined by the alpha component of your materials only, so the objects in your scene will look the same as they did in IRIS GL.

Web22 de set. de 2004 · A different way to do this is to do the “full brightness” calculations and darken it by modulation with the “lightmap” like this: gl_FragColor = texture2D (Street,gl_TexCoord [0].st) * texture2D (LightMap,projPos.st); For multiple textures you need to combine the textures and modulate the result. Hmm, if you want that multiple lights ... Web11 de fev. de 2009 · There is a problem here, you are suming twice the ambient and specular contributions thus you get an overbright result.
