-------------------------- is a small Ray-Tracer for the KDE project. It creates pictures of a simple scene containing a sky, a ground, the hell, and one sphere which is centered in the picture. For each object, a number of surfaces can be chosen from the startup dialog.

Installation

Installation of KRay has not been implemented yet. Once I've created the autoconf stuff, it will be very easy. Just do

and everything will work fine. Nevertheless the following is needed:

Using KRay

After starting KRay it will show the Main Dialog. Here you can chose the size of the picture you want to create as well as the surfaces for the different objects in the scene. Once you've done that, you can press the "Generate" Button or chose "Generate Picture" from the File-Menu and a new picture will be created.

The menubar

The contents of the menubar are rather self explanatory, because it contains only a minimum set of options. Further options will be added in future versions.

Chosing the picture size

For chosing the size of the picture I recomment retaining the 4:3 ratio, since it gives the best effects. You are however welcome to experiment ;-). Note that generating a bigger picture will take more time (you didn't expect that, did you ?) Generating a 400 by 300 pixel picture takes about 90 seconds on my Pentium 133 running Linux.

Chosing surfaces

The program offers different surfaces for the objects, which differ in color, reflection, and transition. Since the sky and the hell cannot be reflecting or tranient, the selection of surfaces for these objects is more limited than for the other objects. Note that the surface of the "Hell" can only be seen, when a transient surface (i.e. water or glass) is chosen for the ground.

Bugs

No Bugs known, but I haven't been testing too much ;-)
