CUDA-based Particle Tracing in Time-variant Tetrahedral Grids
The tracing of massless particles through the unsteady flow field of a time-variant domain is a convenient way to visualize the flow data resulting from computational fluid dynamics. This Video presents an approach for the particle tracing in time-variant domains resulting from real-world simulations, whereas the movement of the particles is calculated entirely on the GPU using the CUDA framework. The simulation data is given by several temporal states of the time-variant domain which are represented each by a tetrahedral grid with embedded flow field velocities. Inside an immersive Virtual Reality environment, the time-variant flow can be interactively explored while an intuitive user interface is provided at the same time for the creation of particles within domain under investigation.
