Open PhD positions at RWTH Aachen
Currently, we have open PhD positions (full position, E13) in the Computer Animation Group ( https://animation.rwth-aachen.de ) at RWTH Aachen University. The research of the Computer Animation Group focuses on the physically-based simulation of rigid bodies, deformable solids and fluids in interact...

New open-source fluid dynamics library
Hi, a few weeks ago we published our fluid dynamics code as open-source library: https://github.com/InteractiveComputerGraphics/SPlisHSPlasH Current features: - SPlisHSPlasH implements current state-of-the-art pressure solvers (WCSPH, PCISPH, PBF, IISPH, DFSPH) to simulate incompressibility - the li...

Re: New physics library - PositionBasedDynamics
I don't think that position-based dynamics is appropriate for engineering analysis. In PBD the material behavior depends on the number of iterations, the discretization and the time step size. Hence, you won't be able to get accurate results for a specific material. PBD was developed for computer ga...

Re: New physics library - PositionBasedDynamics
Hi, the next features of the PBD library will be: - Generic constraints (which are great to test some new constraint functions, you just have to implement the constraint as callback function) - an OpenMP parallelization of the demos - demos for collision handling - a unified solver for rigid bodies,...

Re: Bender's error correction
Hi, I don't know what you mean with "the position correction considering the stability". Maybe the following paper can help you: http://i31www.ira.uka.de/~jbender/Papers/STAR.pdf For computing the impulses p you must solve the following linear system: J M^-1 J^T p = dv where J is the Jacob...

Re: Bender's error correction
Can you specify your problem with the method?Hi, I am new here. I am trying to understand the bender's error correction in a bilateral constraints problem. Can anybody give me any help on that? Thanks!

Collision detection for cloth
Hi,
for my physics library I need a collision detection for a deformable triangle mesh (=> cloth).
Which collision shape is recommended for this?
Does Bullet detect self-collisions?
Cheers,
Jan

Re: OpenCL vs. CUDA
The main issue is that OpenCL is an open Khronos standard supported by multiple vendors, including ATI, Intel and NVidia. CUDA is proprietary to NVidia only, so if NVidia is your main sponsor you might want to choose CUDA :) That's research. It must only run fast on my machine :wink: But maybe I wi...

Re: OpenCL vs. CUDA
Hi, Also, OpenCL is supported in more hardware platforms, either GPU-based or not, taking advantage of the available processing power in the machine. ATI cards (since 5xxx series) offers OpenCL support too. I think the support of different platform types is only interesting in theory. If a program i...

OpenCL vs. CUDA
Hi,
I want to parallelize my simulation method for the GPU. Now I wonder, if it is better to start with CUDA or if I use OpenCL.
Can anybody tell me where are the advantages of CUDA and OpenCL?
Cheers,
Jan

Re: about Jan Bender's one-shot contact clipping algorithm
Hi, the algorithm is very simple. It works for convex polyhedrons. Usually the collision detection delivers one pair of contact points and a contact normal. The algorithm searches for further contact points in the neighbourhood to detect face-face, edge-edge and edge-face contacts. First of all you ...
