Bachelor Thesis

This page is about my bachelor thesis which a finished in 23.1.2017. It also was featured at the CAA Workshop 2017 (German).

Title: Rendering and lightmodels of caves


The analysis and simulation of light distribution with the computer allow a discussion about
human light perception at different points in the room and gives information about positions
with good lightning conditions for new lights or shows potential places of lamps from the past.
The techniques described in this thesis and the raytracer PearRay, together with the new
developed add-on for the open source modeling software Blender, provide a solid foundation for
the investigation of light transport simulations, with the use of radio- and photometric units.
Using the example of the Ardales cave, which is placed in southern Spain and is well known for
its cave paintings (HZP + 16), six computer simulations, based on the work of Dirk Hoffmeister
(Hof16), were performed at three different spots of the 3D-model of the cave. The results
demonstrate that a better and precise analysis can be done by splitting the level of human
perception into the three levels photopic, mesopic and scotopic and segmenting the simulated
luminance into the above-mentioned categories, than by merely viewing color images. The
obtained information confirms the precision of the method and the assumption, that more than
the originally known light sources are necessary to illuminate the cave. The use of PearRay
allows the analysis of all kinds of models and gives plenty room for improvement due to his use
of an open source license.


Unfortunately the thesis is only in German available. If there is interest in reading it please contact me. There is no publicly available version online at this moment.


The scripts which I used in the bachelor thesis, together with the software PearRay, will be soon online.
