	"index", "index into the active color map"
	

Notes
=====

This is the color which will apply to geometry in the currently opened segment/geometry. Since the index can be a floating point value you can apply fractionalcolor interpolation to a surface to get the visual effects often required for Finite Element Analysis and Computational Fluid Dynamics models. For detailed information on what this means in the HOOPS/3dGS refer to the ``Set_Color_By_FIndex`` specification in the 3dGS Reference Manual.
