VORT - a very ordinary rendering tool-kit. Version 2.3.1
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.
Brief outline of the features of art:
primitives (blobby, box, cone, cylinder, height field, bicubic
patch, polygon, sphere, superquadric, torus, algebraic surfaces,
triangular strips and OFF files. Polygons can be flat and
phong-shaded, colour interpolation can also be done.)
Composite objects.
Constructive solid geometry.
Directional, point, and area sources.
3D procedural texturing, bump mapping, and 2D image mapping.
Adaptive antialiasing through variable-rate "jittered" sampling.
Arbitrary (within reason!) transformations on objects and
textures.
Kd trees, uniform grids and one or two other methods to
speed up rendering. Extra grids/kd-trees can be specfied by
the user.
Basic animation support, via variables, and include options.
tools - some utilities for fiddling around with image files.
docs - various bits of doco on the tools
lib - a 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.
text3d - a simple program for making 3d text by converting Hershey vector
fonts into art composites.
tutes - some C programs for generating some animations that demonstrate
the texturing.
We would like to thank the following people who helped with this release:
Alberto Barsella much bug hunting, ideas, some great scene files,
another pcdisp program, and some mods to super.c.
Henry Chatroop for also surviving a VMS port.
Brad Fowlow for doing the Mac port.
Ole Nielsen, Joe Lappa, and Joel Welling for suggestions
and helping isolate the resulting bugs that we introduced.
Pavel Rozalski for the SGI movie programs and the changes to
make the VORT library read compressed files.
Eric Haines for providing the SPD Databases, which proved
invaluable for debugging and testing the kd-tree in art.
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.
