float	Light_w Light position w component.
float	color [4] Light color

ZVec e0

Paper coordinate system basis vectors and origin in object coordinates. Paper coordinates x, y, (and z) are mapped to object position (orig + x e0 + y e1 + z e2). For the eye-linear TexGens, the basis and origin vectors are transformed to eye coordinates using the modelview matrix in effect at the time the TexGen::setUp method is called. Thus, after setup, the user can switch to a different coordinate system for drawing the paper vertices. e0, e1, and e2 should be orthogonal and the same length.

ZVec Light

Light position in object coordinates. Light position should be given in the same coordinate system as the basis vectors above.

float Light_w

Light position w component. Basically, Light_w should be 1.0 for finite light and 0.0 for infinite light

float color[4]

Light color
