This note is to announce the release of Version 2.3 of the Raster3D 
molecular graphics package. This is a beta release, but the full 
version will not differ substantially from the one now available.

New features in Version 2.3 include
   - internal light sources ("glow" lights)
   - alpha blend channel in output image
   - automatic generation of stereo pairs
   - new patch for Molscript V1.4 to fix some long-standing bugs
     in the Raster3D output mode
   - file indirection in input files
   - various new anti-aliasing options, rendering options, and
     more flexibility in the "rods" utility

The README file for the current version 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. 
	The current version is 3.2b (20 April 1997)
