Bullet Creator creates bullets. The kind of bullets we are talking about here are the graphic things used to indicate separate items in an unordered list. In HTML you can use the <UL> tag to get an unordered list with the items indicated by browser specific bullets. Another way is to be a bit creative and use just the <BR> tag and include your own bullet images with <IMG> tags at the beginning of every list-item. Bullet Creator produces one popular kind of those graphic bullet images: virtually correct images of spheres with an optional shadow cast on the background.
The program reads it's input from an ascii textfile and writes the image specified in that file in 24-bit color depth to disk. In the input file you can specify the color and direction of the lighting and material caracteristics for the bullet and it's background. The place of the shadow can be manipulated by choosing different light directions and elevations of the sphere above the background. The whole rendering is done using Phong's illumination model with ambient, diffuse and specular terms in a simple ray-tracing algorithm.
Besides using just plain colored spheres for bullets in unordered list you can also use a 24-bit .tga image to map onto the sphere to use the image as a clickable image, client side image map or just a graphic in your web-page.
