Detection of closed Gas Regions for LBM Free Surface Simulations
Supervision:
Background:
The simulation of fluids with free surfaces is important for a variety of
technical applications like foaming or casting processes, and moreover, the correct
animation of fluids is still a challenge in the field of computer
graphics. While previous projects were able to simulate the
free surface motion with bubbles and their coalescence, it
was not possible to detect the formation
of new bubbles due to changing regions enclosed in fluid.
The goal of this thesis is the implementation of an efficient and
sufficiently accurate segmentation algorithm
to detect closed regions in the gas phase of a three-dimensional LBM simulation with
free surfaces. This is interesting for both technical as well as
graphical applications.
Task:
-
Implementation of an accurate detection reference algorithm, based
on a given free surface LBM implementation
-
Optimization and accuracy comparison of modified versions
-
Experiments of improvements in visual quality and appearance,
comparing simulation with and without bubble detection
Recommended knowledge:
-
C/C++ programming
-
Fluid mechanics, Lattice-Boltzmann methods (e.g. from the NuSiF course)
-
Visualization (raytracing, OpenGL)
-
Segmentation algorithms
