| The aim of the thesis is to develop and implement a novel method for interactive physically-based rendering of clouds (and other gaseous phenomena, like smoke, dust etc.).
The developed method should have the following properties: - it should be physically-based, that is, although the simulation model can be biased, it mustn’t be purely empirical; the suggested basis for the method is volumetric photon mapping - in the same time, the method has to be significantly faster than the existing methods for offline cloud rendering, to compensate for the compromises in the (un)biasedness; this should be achieved by utilizing GPU for majority of the computations - the method should be able to run on any sensible volumetric cloud/smoke data (that is, it shouldn’t be limited to f.i. cumulus clouds), and should allow these data to change in time to allow medium movement/animation - finally, the method must handle typical properties of cloud media: high particles albedo, scattering anisotropy (arbitrary phase functions), medium inhomogeneities The method shall be implemented in an interactive application that will allow its user to load, browse and navigate around at least a single cloud in its natural environment, the sky. It should also allow the user to dynamically change both technical and physical parameters of the simulation, and relevant scene settings. The elaboration will consist of four phases: 1) the student shall familiarize themselves with the available literature and existing methods that concern with the visual simulation of clouds and related media 2) based on this knowledge, they should propose a new method that fulfills the description above, and attempts to remedy some of the disadvantages or limitations of the existing algorithms 3) then, the application as described above will be created, along with a brief documentation 4) finally, points 1)—3) will be described in the thesis text |
