This page holds links to programs I code. Mainly Computer graphics related and exercises
I do for different courses in university. I'm not going to put every little code here, nor
"experiments". This page is for finished, serious code. Well. Mostly. :)

I'll put some more stuff here later.
OBJ Reader
Parsing 3d objects files (alias|wavefront old format). MSVC++.
Basic GLUT program
Basics of GLUT demostrated. drawing a triangle on screen, changing it's
colors randomly, background colors change (pastel shades), use of mouse to move it, scale it or
leave a trail. C++ source and executable. Basically for linux, can recompiled on windows.
 | 3D Perspective camera
Basically a solution for this exercise. Reads a file describing a perspective projection camera parameters, As well as a list of objects (meshes - bundles of polygons forming together a geometrical shape). Each object comes with three transformations: Translation, Rotation, Scaling. Each mesh will be drawn on the window as if it was seen through the given camera + it had gone through its transformation. Uses depth testing in order to deal with occlusions. C++ course code and executable, basically for linux, can recompile on windows.

 | Dump TGA v1.0
I had an openGL program I wanted to make an avi of, so I wrote this code. This little code will allow you to dump a frame from the screen into a targe image file (lossless). If you'll dump each frame you'll have a sequence of images you can turn to avi using Emil Mikulic's tga2avi (local mirror). C++ source code and executable, linux / windows. A readme.txt inside will explain everything.
Language: C / C++ (OpenGL)

if you do not have PowerPoint Installed you can download a Free PowerPoint Viewer from Microsoft.
Presentations of academic papers I've done for seminars. I do not offer those for download here, since I want to know who gets them and for what, but you can email me and are most likely get it attached with the replay (my presentations are around 2 MB usually). However, my presentations includes movies that I cannot share for copyright issues.
 | Large Steps in Cloth Simulation
My first ever seminar presentation. I did a little lab project on Cloth simulation (with my intention to code a cloth library for games) and chose to present this paper. The algorithem showed in the paper was used for the movie Stuart Little and by David Baraff's advice I've taken ome shots off the movie to demonstrate the outcome. I presented it at 2001 in the Geometric Modeling and Computer Graphics seminar. It shows the basic of making of cloth very good, but the later slides are less good.
Presenting the paper: Large Steps in Cloth Simulation
by: David Baraff and Andrew Witkin, CMU (now both at pixar)
Paper published at: Siggraph 1998 conference
Keywords: cloth,simulation, constraints, implicit integration, Physically-based modeling

For the 3 years CFXweb exists I have written a very big
number of scripts, mainly in Perl and PHP. I can't (and won't) list them all here. I'll only
present here scripts that are ready for release, properly commented, and of some use to people.
 | NewsGrabber 0.6 "Greenfield"
This is a module for any CMS (such as phpnuke) that knows how to
scan a web page of any site, grab the news from it and add them toy your site. The module is
able to process any site which he got a profile of. Profiles are very easy to write yourself
and some working ones - as well as an example profile - are provided in the package.
It's fast, It's free and it's modular. It will also soon support PostNuke and maybe some other
CMSs. Also, it's very easy to change it to fit ANY system - even something you wrote yourself.
This script was tested and ran successfully as an admin module on phpnuke 6.5 - 6.9.
Make sure to read the readme.txt carefully. I take no responsibility for any actions done with this script.
Changes from version 0.5
Major change - Script can now scan MULTIPLE sites in a queue.
Script can now plug into different CMSs, not only php-Nuke.
Look and feel improvments.
Comments? Questions? Need Help? Download Profiles? Over Here.
Language: PHP (no additional SQL tables)
size: 29 Kb
Keywords: news, parser, export, import, news exchange, cms, rss
|
| phpNuke 6.5 Download Module Modification
Modified version of the downloads module of phpnuke 6.5. You can now set the look of each file entry using an external HTML template,
add images to your files etc. Does not require any sql changes. Just replace your files with these ones. Read the README.TXT !!
Language: PHP
size: 24 Kb
Keywords: downloads, phpnuke, modification, image, templates
|
| NuCalendar 0.61 Extended
Extending the phpNuke NuCalendar 0.61 Module. Addes results, sponsors, Logo/Image, Country, Event Website and Event Price
fileds to each event. Still - all these are optional and can be turned on and off from the config file added. Hopefully all these changes will be added
to the official released of NuCalendar 0.62.
Language: PHP (SQL changes included)
size: 6 Kb
Keywords: phpnuke, nucalendar, events, extended

These are here for, well, the use of someone... ;)
Ex2 - Formal Description
Contains: Simple Sort, Quadratic eq. solver.
Ex3 - Formal Description
Contains: Summing a mathematical progression, Printing Divisors,
Printing a multiplication table,
Printing a triangle of characters,
Printing an empty square of characters.
Ex4 - Formal Description
Contains: A Soldier class, a Dice class with a Probablity
calculation for resutls,
a Fraction class with a PI Approximation example.
Ex5 - Formal Description
Contains: Interface versus implementation - The IPoint and ITrapezoid classes
Implementing an algebric vector - class AlgebraicVector, and testing it.
Ex6 - Formal Description
Contains: Implementation of a Matrix class, using the AlgebraicVector implemented in ex5
and Testing it, EquationSolver - Solving a set of linear equations using Gauss Elimination
Other Java Stuff
- Triangles - (Output Image)
This program finds the type of triangle according to user input. The user enter the length of each edge and the computer will tell what a triangle it is.
Types handled: equilateral triangle (All edges same size), isosceles triangle (2 of the edges are same size) and sceles triange (Each edge a different size).
-- Uses javax.swing.JOptionPane
- Matrix Array - (Output Image)
Creates a double array of 5x5 (matrix), Fills it with random numbers, finds the largest number in each row, calculates diagonal sum.
-- Uses javax.swing.JOptionPane

Other code I made for different uses and I thing you can find usefull.
ReExec
Ever wanted to execute a command or a program every several
minutes or seconds? This is a tiny java source code class that will do exactly that.
I coded it to run a program that uploads/downloads a certain file to/from
cfxweb.

Code I want to examine for later use.
Webcam Source -
Visual C++ Full source For webcam handling.
freeVCR -
Visual C++ Full source For webcam & video handling.
cURL -
Executable and full C/C++ source code. This excellent util allows you to transfer files
with URL syntax, supporting FTP, FTPS, HTTP, HTTPS, GOPHER, TELNET, DICT, FILE and LDAP.
Curl supports HTTPS certificates, HTTP POST, HTTP PUT, FTP uploading, kerberos, HTTP
form based upload, proxies, cookies, user+password authentication, file transfer resume,
http proxy tunneling and a busload of other useful tricks. Both sources and executable are
very handy.
