Simulation of orographic clouds


Martin Čáp Supervisor: Jaroslav Sloup Master thesis 2019
Realistic cloud simulation is a hot topic in computer graphics research. In this thesis we present a possible approach of modeling orographic clouds using SkewT/LogP diagrams as proposed by Rui Pedro Duarte. We extend this simulation with well-known Lattice Boltzmann method to simulate wind and its effects on clouds in mountainous environments. We parallelize both methods on the GPU using CUDA technology by NVIDIA. Lastly, we propose a simple extension of volumetric rendering method by Simon Green that uses phase functions to enhance graphical fidelity of our cloud images. We present this simulator in a simple to use application that gives its users a wide variety of tools to create desired results.
