				RASTER3D

PROGRAM:
	Raster3D is a set of tools for generating high quality raster 
	images of proteins or other molecules. The core program renders 
	spheres, triangles, and cylinders with specular highlighting,
	Phong shading, and shadowing using an efficient Z-buffer algorithm. 
	Ancillary programs process atomic coordinates from Brookhaven PDB 
	files into rendering descriptions for pictures composed of ribbons, 
	space-filling atoms, bonds, ball+stick, etc.  Raster3D can also be 
	used to render pictures composed in other widely used programs,
	including Molscript, VMD, XtalView.  Output is to pixel image files
	with 24 bits of color information per pixel plus an optional alpha
	blend channel.

AVAILABILITY:
	Raster3d is freely available but unsupported.
