### GL (Options)

The options that begin with the "GL_" prefix allow you to specify certain lighting parameters that affect what your model looks like in the Graphics Display window:

GL_AMBIENT, GL_AMBIENT_AND_DIFFUSE, GL_DIFFUSE, and GL_SPECULAR represent the ambient intensity, diffuse intensity and specular intensity of the light source respectively.

Entry Type: Character String number or an integer of 1 or -1. For example .2 specifies 20% of the positive range, .8 specifies 80% and 1.0 specifies 100% (or most positive representable integer value, while –1.0 specifies the most negative representable integer value). If a number exceeds the range of –1 to 1, the corresponding integer return value is undefined. The default value for these entries is zero.

GL_SHININESS represents the specular exponent of the material.

Entry Type: Character String number or an integer. Generally an integer value of 0 to 10 is a sufficient range. The default value is 10.
