Digital holography, Hologram generation
A hologram provides a view on a scene similarly to the real world and it can be
used to display a virtual scene because it can be simulated numerically. However,
the simulation is a computationally extensive task. Therefore, we accelerate it
through enhancing the Detail Driven Method. The design of the original method
allows us to reduce the number of samples and to limit variability of the
elements without restricting the scene contents. No modification limits
diffusiveness of a surface and no modification requires a minimum distance
between the scene and the hologram. As a consequence, the computation time is
reduced approximately 5x in a case of a common scene. Hence, the method is able
to calculate a hologram of 4096x4096 samples from a scene of 800 triangles in
about 3.1 hours on a regular 2.4 GHz CPU without any special hardware. This shows
flexibility of the method and it indicates that the method is acceptable for
practical use.
