	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:

	Department Of Engineering Computer Resources,

	Parkville, Vic, 3052, Australia.

Enjoy.

======================================================================

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.

============================================================================

Just in case anyone is interested there is more Free stuff available
from the same sites as mentioned above.

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.

This software is public domain and may be used for any purpose commercial or

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.
