Hello there... I just grabbed a copy of 'prt' off of a.s earlier this morning, and got it running with no problems at all. My only problem is what to do with the 1.68MB output file I got. What package[s]/monitors etc. do I need to view them? Feel free to mail if you prefer. If others need the information, I'll gladly post a summary. It worked great, by the way. We had a couple of sun 4/65s that weren't doing much, so... ;-) Thanks, Tony Foiani -- Tony Foiani a.k.a.

If others need >>the information, I'll gladly post a summary. The output appears to be in "mtv" format. To convert the format to something viewable, grab a copy of "PBMPLUS" or the "fbm" utilities. Those packages can convert the mtv format to something usable, such as Amiga IFF, SunRaster, etc. -- dean@coplex.UUCP Dean A. Brooks Copper Electronics, Inc. Louisville, Ky UUCP: !uunet!coplex!dean

If others need >>the information, I'll gladly post a summary. Well I downloaded the raytracer as well. The format of the file is fairly straightforward so I wrote a quick c program to get it into a form I could use. The file contains a newline termintated string containing the X and Y dimensions, followed by X * Y * 3 bytes. ( I guessed at the order (RGB)) I then took the three files generated and loaded them into PICLAB a DOS based program, in raw mode. I was then able to convert it to GIF format. Here is the program I wrote: BEGIN------------------8<---------------cut here----------8<---------------- #include <stdio.h> main(argc, argv) int argc; char **argv; { char *pixbuf, *r_name, *g_name, *b_name; FILE *infile, *rfile, *gfile, *bfile; int x, y, row, col; if ( argc != 2 ) printf( "Usage: rgbsplit filename" ); if ( (infile = fopen( argv[1], "r" )) == 0 ) { perror( "rgbsplit" ); exit(1); } r_name = (char *) malloc( strlen( argv[1] )+4 ); g_name = (char *) malloc( strlen( argv[1] )+4 ); b_name = (char *) malloc( strlen( argv[1] )+4 ); strcpy( r_name, argv[1] ); strcpy( g_name, argv[1] ); strcpy( b_name, argv[1] ); strcat( r_name, ".r8" ); strcat( g_name, ".g8" ); strcat( b_name, ".b8" ); rfile = fopen( r_name, "w" ); gfile = fopen( g_name, "w" ); bfile = fopen( b_name, "w" ); if ( !( rfile&&gfile&&bfile ) ) { perror( "rgbfile" ); exit(1); } fscanf( infile, "%d %d\n", &x, &y ); if( x <= 0 || x > 2000 ) { printf("rgbsplit: Error in format\n" ); exit( x ); } pixbuf = (char *) malloc( x* 3) ; for ( row = 0 ; row < y ; row++ ) { fread( pixbuf, 1, 3*x, infile ); for( col = 0 ; col < 3*x ; ) { fwrite( &pixbuf[col++], 1, 1, rfile ); fwrite( &pixbuf[col++], 1, 1, gfile ); fwrite( &pixbuf[col++], 1, 1, bfile ); } } } END-----------8<----------cut here----------------------8<---------------- -- ________________________ / __ \ | Michael J.
