SunSky |
This is a wrapper around Utah's sun/sky model code. The original paper,
"A Practical Analytic Model for Daylight", is available ,
and the authors kindly released the core source code
for the method.
What I've done is add a wrapper that uses the Utah code
to draw plots of the entire sky or a specific window of the sky. As a bonus,
it draws the CIE diagram, and various spectra, including blackbody and the
CIE basis functions.
To build the sunsky program you'll need VL, the vector
library below.

VL Vector Library |
| VL provides 2-, 3- and 4-vector and matrix types, arbitrarily-sized
vector and matrix types, sparse and sub-region types, and lots of useful
functions and arithmetic operators defined on those types. It includes a debugging
version of the library, with range-checking of all indices. It comes with
a number of numerical routines such as Gauss-Seidel, conjugate-gradient, QR
and SVD factorization. |

ChangeLog
(Note: if the rpm breaks under your particular distribution, you can rebuild
it by downloading the tar file and running "rpm -tb vl-1.3.2.tar.gz".)

SVL Vector Library |
| This is a simpler, cut-down version of VL; probably a better
starting point for small projects. It contains just the small-size and generic
vector and matrix types. |

MacFork |
| A unix utility for extracting resources from a macintosh resource
fork. Currently macfork only directly supports icon families, pict files,
and palettes, but any resource data can be extracted to a file. |

This stuff is really very dated. I leave it up here mostly for nostalgia
purposes.
BibFrame for FrameMaker 5.5
There is a nice little system for using BibTex references under FrameMaker
called "bibframe". The latest version, 0.8.1, is supposed to work with frame
5.0, but has a couple of problems, and the macros break under the most recent
version of frame, 5.5. I have updated this with macros that work under framemaker
5.5 (and hopefully are backwards compatible with 5.x), and a bug-fix to
bibframe that solves a problem with specifying reference directories. Download
bibframe-0.8.1-fm55.tar.gz

GLXForms
For those people being forced to swap from old GL to OpenGL, or graphics
hackers wanting to use the xforms library, this contains a simple demo of
how to use the xforms library with OpenGL. Download glxforms.tar.gz
.
Simple Client/Server
I find this useful for quick network hacks. Contains a simple client and
server which together allow you to pipe the input and output of unix commands
over the net. I also have some code lying around to let you script telnet
sessions, which I'll put here when I can find it. Download clientserv.tar.gz
.
Client-sensing httpd
httpd-agent-patch.Z
contains patches for NCSA's httpd which will allow it to serve different
versions of a page depending on which client is accessing it. For instance,
you can arrange it so that if netscape accesses a particular page, it gets
a version with lots of whizzy extensions only it can handle, whereas if Lynx
is used to access the same page, it gets a vanilla version with no inline
GIFs or other fancy extras.
Snap
snap.tar.gz
contains all the scripts I use to run GooberCAM
. [Sadly goober died shortly before I left CMU.]
ErrorNames Extension
An extension for the Mac that provides proper error names and descriptions,
rather than the usual uninformative error numbers. Currently a development
release. Download it from here . |
