Application

Flame screensaver
I found this great IFS application, Flame from Scott Draves. It can be found here. This program was created by trying to find out how his program works. The screensave churns out 'flames' in the quiet hours of your PC and saves them to disk.
Updated 20-02-2002
- Fixed decimal seperator bug.
- View other images while rendering.
- Test for black and dark images.
- More user settings

This application calulates the noise of traffic using the simple dutch calculation method (srm1). Dutch only.

My first javascript
I've started playing around with javascript and build this simple clock script.

Nagalm
The only uses of javascript I've seen on the web is form validation and special effects. Wondering if javascript can be used to create complexer programs, I've tried to rebuild my first real Delphi program. The script works nicely in IE, but Netscape's support of DHTML is inadequate.
(Sorry, the page is only available in dutch.)

Clientside sortable table
Make tabular data sortable without regenation of the pages at the server. Simply put all the data in a two-dimensional grid and say witch columns should be sortable and visible, which column contains a link and which columns should be made as links.

TinyPTC for Delphi

TinyPTC is a lightweight graphics library I found on www.gaffer.org. The library was exaxtly what I needed for some of these freubles. The only drawback was the orginal code was in C. This Delphi version is an almost direct port of the C-windows version 0.8. The library does not use the visual part of the VCL, making it possible to create application smaller than 40K.

Julia animation 6
I found a great article on a different way of showing a mandelbrot, showing it with 'rings'. After cutting a few corners for speed the algorithm was still fast enough for a realtime julia animation.

On www.gaffer.org I also found the following program.
This progam was the basis for the swirly programs below.

Smoke
On the The good-looking textured light-sourced bouncy fun
smart and stretchy page I found a simple application which shows a very realistic smoke effect. It's an easy effect to create using a noise function.

Voronoi
Voronoi diagrams are a collection of polygons created from a collection of points where het area of a polygon then point in the polygon the closest point is. Combing voronoi diagrams with a noisemaps can give a nice marble patern without the usual long bands.

Zoom
One of the most basic effects, simply added to make this collection compleet.

Lights
On cfxweb there is a java contest for lightning effects. I have been playing around with the effects and found a couple of way to do this.
The first method walk from a 'lightsource' to the edge in grid like patern and adds a light value depending on aprevious handled point.
The second method cast lines from the lightsource to the edge. Light value is added depenant on the passed pixels. This method gives the impression of light rays. Also the values can be changed per ray.
The third method is a small adaption on thesecond method that only the fist couple of pixels are used to determin the light value and the ray is pasted on top of the original image. Another example using curved lines.
A fractal as image is not the best way to show these effects, but it was something easy I had laying around.

Lens2
I saw this lens effect on Jan Horn's site. He was using a texture map in OpenGL. The effect is also fast enough to do on a per pixel basis.

TinyGL

TinyGl is an framework to create small simple opengl applications containing only one screen. The code is based on TinyPTC bypassing the dependance on the visual parts of the VCL. Using this framework can keep your delphi applications under 40K.
