Elasto
elasto.c
A simple physic simulation of a mesh of masses connected by springs. You can drag the masses with the mouse and the four corner masses stay in position.
How to run
elasto nbx nby lx ly k m frot
- nbx and nby: number of masses horizontally and vertically
- lx ly: equilibrium lengths between masses
- k: spring coefficient
- m: mass of each mass
- frot: coefficient of friction
Requirements
SDL. Compile for instance with:
gcc -o elasto elasto.c `sdl-config --cflags --libs` -Wall -ansi -pedantic -O2
GNU GPL v2
Network thingies
TinyChat: a peer to peer chatting toy. Requires SDL, SDL_image, SDL_net. Public domain.
echo: a simple multiuser echo server in Lua. Requires LuaSocket. To test is you can connect to it with telnet. GNU GPL v3
resolve.c: a very basic domain name resolution utility. Requires SDL, SDL_net. Public domain.
sdlharmo
Lets you change in realtime the harmonics of a constant pitch sound, to explore the different timbres that result.
Interesting for the sound generation: includes a basic oscillator for the fundamental, from which are deduced the harmonics, which are finally weighted with the coefficients given by the slides in the window.
Requires SDL. Public domain.
soli
A Lua script that models the card game of solitaire, and also an artificial "intelligence" that plays as I would do.
The script plays many games and counts the ratio of success.
Public domain.
Clifford Attractor
My attempt to reproduce the images found here
Requires Paul Bourke's library for the image output.
Public domain.
Ortho
A 3D "engine" written from scratch, just for the fun of it. It has an orthographic camera, points and lines, a z-buffer, etc.
This demo shows random lines in a box, and you can rotate the view with the mouse or arrow keys.
Download. Requires SDL. GNU GPL v3
360
A sphere map viewer, written from scratch (no 3D engine). Pretty slow too... Use arrow keys to rotate the view.
360.c
Requires SDL, SDL_image. GNU GPL v3
Free trees generator
A script to generate all free trees up to a certain size, and output SVG images of them
See the page A bunch of dots, for souce code, friendly explanation and the images of the 13188 trees up to size 15.
