Graphics at Holmes3D.net
This site contains articles and software that I,
Ryan Holmes,
have written. These are quite old now, and kept merely for historic purposes.
Topical Articles
This collection began as resource pages for the Introduction to Computer Graphics
class at
Arizona State University, which I co-taught during the 2003-2004 academic year.
Each page describes or introduces a topic in computer graphics.

The Utah Teapot is a frequently
used dataset in rendering. This page briefly describes the teapot's history and makes
the dataset available for download.

A Quick Introduction to Subdivision Surfaces
briefly discusses several subdivision surface schemes, shows examples, and links to
other webpages with more information.

An OpenGL Skeleton
contains a Visual C++ 6.0 MFC project with a basic OpenGL window. This skeleton code
may be useful if you are interested in experimenting with OpenGL in a VC++/MFC environment.
A step-by-step walkthrough with commentary on the creation process is also included.

OFF Files
describes the OFF file format many of my programs use, provides old sample code
for loading and saving a basic OFF file, and includes links to other programs that
use OFF files. If your program uses an OFF file and you'd like it to be mentioned
here, contact me.

The DCEL Data Structure for 3D Graphics
describes the doubly-connected edge list data structure with emphasis on its use for
computer graphics. I include a small OpenGL program for visualizing a DCEL and example code
for the basic structure.

Software
These are homepages for the various applications I have written for modeling
and rendering 3D objects.
|
RoffView was my first
3D application. I expanded and rewrote it over the years, but my more recent applications
have largely subsumed its functionality.
|
|
MeshMan is a direct descendent
of RoffView, incorporating code from a number of my class projects over the course
of my Master's program.
|
|
Vorpal is a volumetric modeling
tool, suitable for creating STL files for rapid-prototyping.
|
|
Yar is Yet Another Raytracer,
implementing distributed raytracing and photon mapping for OFF files.
|
|
Tricelpa is a particle engine
for experimenting with particle effects. It has a companion program, TricelpaSaver, that
allows those particle effects to be used as a Windows screensaver.
