A Ray-Tracer prototype:

There are 2 techniques to render 3d objects to the screen:

1. raytracing
2. rasterization

Here, I apply the basics of the implementation of the raytracer technique.

This is a mid resolution Picture of a Sphere and a light reflection.

This is a low resolution "M" Letter printed on screen with spheres.

Notes:

1. No Bias is added to the doubles, thus leads to some incorrect calculations when the objects become a bit further in the scene from the camera.
2. Aliasing is not added which makes the objects edges looks rigid (as if you are using win32 GDI rendering ;).

Further-Dev-Notes:

1. Adding refractions.
2. Adding textures and world view.
3. Adding Triangles.
4. Pollishing and reduce the Delta Error (Errors from heavy double calculations).
