Realization

A standard technique around photo-realistic pictures to compute, is the so-called Ray Tracing : To each point of the film surface we look for the origin of a ray of light hitting there. In addition each ray of light is backwards pursued from the camera, until it meets an object which can be explained.

The usually used Ray Tracing procedure be based on a straight-line infinitely fast light propagation in a three-dimensional Euclidean area.

These bases are no longer durable in the proximity of compact cosmic objects. In this work the Ray Tracing procedure in two important points is therefore extended:

• Transition from the three-dimensional area to four-dimensional space-time: Thus relative to moved objects with consideration of light running times, aberration, Lorentzkontraktion, Doppler effect can u.s.w the camera. physically correctly and mathematically simply to be represented.
• Transition from a flat to space-time any curved: Thereby effects are seized which result from gravitative light diverson or from the unusual causal structure in the proximity of a black hole.

With these verallgemeinerungen will it possible to come into however environments everyday inconceivable on earth in the universe to physically correct pictures.
