It would be nice to use textures. Especially for the skybox and normal mapping.

The raytracer is horribly slow. Maybe implement a KD-tree or octree.

Fresnel adds whiteness around objects (when the angle between ray and normal is very big), creating more realistic effects.

The bounding box is incorrect when the object is rotated.
Also affects the scene bb for obvious reasons.

Wiith appropriate keyboard, draw and render functions.
Contains scene?

For nicer reflection, shading and refraction

Currently, when sending the shadow-ray, the object the ray is shot from is skipped. Otherwise, the ray always touches the self-object, causing a full-object shadow.
A possible fix might be to add 0.01f (or so) of the normal to the hitpoint, and then not skip the object.
