Sorry if you've seen this before but..... Vort 2.0 is now 'officially' available from the following sites: gondwana.ecr.mu.oz.au [128.250.1.63] pub/vort.tar.Z munnari.oz.au [128.250.1.21] pub/graphics/vort.tar.Z uunet.uu.net [192.48.96.2] graphics/vogle/vort.tar.Z (uucp access as well ~ftp/graphics/vogle/vort.tar.Z draci.cs.uow.edu.au [130.130.64.3] netlib/vort/* Australian ACSnet sites may use fetchfile: fetchfile -dgondwana.ecr.mu.oz pub/vort.tar.Z or obtain it from the Australian Netlib at draci.cs.uow.oz Eric H. Echidna. What follows is the README file for Vort. ================================================================ VORT - a very ordinary rendering tool-kit. Version 2.0 VORT is a collection of tools and a library for the generation and manipulation of images. It includes a ray tracer, pixel library, and utilities for doing gamma correction, median cuts, etc... The current distribution is described as follows: art - a ray tracer for doing algebraic surfaces and CSG models. Art supports the following primitives: polygons, offfiles, rings, disks, torii, superquadrics, spheres, ellipsoids, boxes, cones, cylinders, and algebraic surfaces. Tile patterns can be mapped onto all of the above except algebraics, boxes, and offfiles. The following textures are supported, bumpy, wave, marble, wood, ripple, fuzzy, stucco, spotted, granite, and colorblend. The ray tracer uses an acceleration technique based on the spatial kd-tree. tools - some utilities for fiddling around with image files, and converting between various formats. These include tools for converting nff files to art format, and vort files to ppm format (and ppm to vort). docs - various bits of doco on the tools lib - the pixel library files - this has only been developed to the point needed to read and write display files. old - this contains a program for converting image files from 1.0 format to 1.1. sun - a set of display programs for a sun workstation. X11 - a set of display programs for a 256 colour X machine. iris - a display program for an Iris workstation. pc - a set of display programs for a PC with VGA Extended Graphics. movies - some C programs for generating some sample animations. tutes - some C programs for generating some animations that demonstrate the texturing. text3d - some C routines that read in the hershey fonts provided with VOGLE and use them to generate 3d text. Example input files are provided. We would like to thank the following people who helped with this release: Alberto Barsella much bug hunting, ideas, some great scene files, and another pcdisp (showpix) program, plus the colourblend texture. Henry Chatroop for also surviving a VMS port. Joe Lappa for suggestions and bug hunting. Ole Nielsen for vort2sun, bug hunting and ideas. Eric Haines for providing the SPD Databases, which proved invaluable for debugging and testing the kd-tree in art. Mahesh Neelakanta for providing artd, and dart. This software is public domain, and provided without guarantee, although if you send beer (use the snail mail address, it's less messy) we will drink it. Surfaces, material properties, and general chat can be directed to: echidna@munnari.oz.au echidna@ecr.mu.oz.au or by snail mail to: The Software Support Programmer Department Of Engineering Computer Resources, Faculty Of Engineering, University Of Melbourne, Parkville, Vic, 3052, Australia. Enjoy.

Echidna. ====================================================================== VOGLE 1.2 fixes some bugs and includes some speed ups from previous versions of VOGLE. Specifically, all matrix stack manipulations are now 'done in place' to save time. VOGLE stands for "Very Ordinary Graphics Learning Environment". VOGLE is a device portable 3D graphics library that is loosely based on the Silicon Graphics Iris GL. VOGLE also supports 3D software text in the form of Hershey vector fonts. The directories in this distribution contain the source for the VOGLE library. They are as follows: docs contains the documentation such as there is. drivers contains the source to a variety of device drivers, currently restricted to: postcript, sun workstation, apollo workstations, X11 (R2, R3 & R4), tektronix (401x), hpgl, dxy, and the ibm pc cards: hercules mono, cga, ega, vga and sigma. examples contains some C and FORTRAN programs useful both in testing and (hopefully) learning how to use it. hershey contains the source for generating fonts and the hershey data for the occidental and oriental character sets. src contains the source for the C VOGLE interface, and the source for the FORTRAN interfaces where available. This software is public domain and may be used for any purpose commercial or otherwise. It is offered without any guarantee as to its suitability for any purpose or as to the sanity of its writers. We do ask that the source is passed on to anyone that requests a copy. Although VOGLE is public domain we will drink any quantity of Beer you send to us. Regards, Eric H.

README for vopl: ============================================================================ The directories in this distribution contain the source for the VOPL library, and the graph plotting program gpp. They are as follows: docs contains the documentation such as there is. examples some C and FORTRAN example programs. gpp contains the source for the plotting program gpp. src contains the source for the VOPL library and the source for the FORTRAN interfaces. VOPL is a library of routines for doing fits and graph plots written using the VOGLE graphics library. We are still developing VOPL so constructive comments and Beer are always welcome.

We do ask that the source is passed on to anyone that requests a copy. As Godzilla once said, "Gad, what food these mortals are."

Oh, yeah, I forgot... There are several scenes and output images from the raytracer art available on gondwana.ecr.mu.oz.au [128.250.1.63] in the directory pub/images. These images are 8 bit sun rasterfiles and can be converted to other formats using (for example) pbmplus. There are also some simple 36 frame movies in the directories pub/movies/* . These files are in VORT format and can be displayed with the movie programs that come with VORT or can be converted to another format using the vorttoppm program that comes with VORT. Eric.
