WebIt is legal to use values between -1.0 and 1.0 as the color components for the ambient light; only values between 0.0 and 1.0 are legal for light sources. Using negative values for the ambient light serves to darken the overall scene. For additional light sources, enable and configure GL_LIGHT1, GL_LIGHT2, etc. A maximum of 8 lights is permitted. david popovici 400 m roma https://jfmagic.com
