			RASTER3D V2.1
This note is to announce new distribution addresses (ftp and www)
and a new version (V2.1) for the Raster3D graphics package.

	ftp:	ftp.bmsc.washington.edu
	www:	http://www.bmsc.washington.edu/raster3d/raster3d.html

	V2.1 is not substantially different from the previous version.
	The primary change consists of support for additional surface
	properties during object rendering. This addition should, for
	example, facilitate the extension of existing programs to emit 
	Raster3D input files describing molecular surfaces.

The current README file is appended below.

	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 Per Kraulis' MOLSCRIPT program 
	in glorious 3D with highlights, shadowing, etc. (NB: you will need 
	MOLSCRIPT V1.4 to get the full benefit of this).  Output is to 
	pixel image files with 24 bits of color information per pixel.

	Raster3d is freely available but unsupported.
