In the latest version of VM_pRAY (VM_pRAYjul90.tar), the image format may be either ppm or mtv. ppm (portable pixmap file format) Copyright (C) 1989 by Jef Poskanzer. utilities to convert ppm file (24bit) to either sunraster, GIF, ... are available from ftp.ee.lbl.gov [128.3.254.68]: *pbmplus.tar.Z*. , via anonymous ftp mtv (output from Mark VanDeWettering's ray tracer) you can: 1) If you get the ppm package, a use of the ppm utilities may be ppmquant 256 < image.ppm | ppmtogif > image.gif xloadimage image.gif 2) If you don't want to install the ppm package, you can use utilities from our site irisa.fr [131.254.2.3]: */iPSC2/VM_pRAY/color This directory contains programs to display an image 24 bits on 8 bits screen running under X window system: The routines generated accept the image format procuced by VM_pRAY (either mtv or ppm): Xnb: display the image with grey level. use: Xnb < image.mtv or image.ppm Xrvb: a simple program to display an image color. (not very pretty but fast). use: Xrvb < image.ppm or image.ppm comp24to8: generate a 8 bits image color with a good colormap compression. The 8 bits image is stored as a sun rasterfile file. use: comp24to8 < image.rvb > image.ras or image.ppm display: xloadimage image.ras -Hope this help, -didier badouel.
