Re: Co-ops or contractors for 3D physics simulation at AMD

To be clear, fluid and rigidbody simulation positions are separate. So you don't need to meet the requirement for both.

And I encourage Ph.D students to apply for co-ops. This work may require some type of research.

Finally, I will be more flexible with location.

Co-ops or contractors for 3D physics simulation at AMD

I am looking for co-ops or contractors for 3D physics simulation engineering at AMD. Fluid simulation 1. Must have a solid background on Eulerian and Lagrangian approaches 2. Good understanding on two way interaction between fluid and rigid bodies 3. Surface reconstruction from particles such as ani...

Re: Beginner question: hair simulation

Hi Alessandro, I just came across your post. It is more than year old and you may have already found something but I just reply to your post in case anyone is interested. I worked on hair simulation for TressFX and the source code is released in the AMD web site as linked below. http://developer.amd...

Re: Cloth simulation

Since my previous posting, I've been developing my own simultaneous proximity and continuous collision handling method for cloth simulation. I tried a couple of approaches like ones linked above and was not satisfied much. Below is a link to my current approach in youtube. http://youtu.be/6yKrcV16k6...

Re: btSoftBody SetWindVelocity issues

Hello THEKING, Can tell me which Bullet version you are using? The latest one (2.79) has a patch for wind effect and the implementation is different from the previous version. Also if you can provide me code, I will be happy to try it. Just one thing is that I will only be able to use my computer af...

Re: Building and running OpenCL demo in Nvidia platform

Hi, After some modifications, I was able to run Bullet OpenCL demos in NVidia environment. Below is a list of modifications. 1. Since ATI Stream SDK is not installed in my machine, I converted "$(ATISTREAMSDKROOT)lib\x86\OpenCL.lib" to OpenCL.lib in Additional Dependencies property for three OpenCL ...

Re: My explicit euler cloth code

Just my 2 cents about Explicit method.. 1. The force between two points are not constant even during the discrete time step. We already know that the force is changing as a result of moving points. The good thing is that we can compute how much the force will change during the time step. Unfortunate...

Re: OpenCloth: A new opensource project for cloth simulation

I briefly took a look at the source code and believe your code provides great value to many people out there. I am personally interested in cloth simulation and have been working on it for a while. I believe there are not many 'clean' code which implements implicit integration. Especially Baraff & W...

Re: Simulation/viewer movie files

If you don't need a nicely rendered animation movie, then what about capturing screen with Windows Movie Maker? I am not sure it is the right name though. It is a part of windows OS.

Re: Simulation/viewer movie files

I am sure there will be many different approaches. What I usually do is that I save the each frame (object) as obj file format and load the sequence of obj files into Maya using the plugin below. http://code.google.com/p/animobj/ I actually made the plugin for that purpose. If you have multiple obje...

Building and running OpenCL demo in Nvidia platform

Hi, I am probably jumping the gun without searching the previous posts thoroughly. I was trying to run OpenCL cloth demo in Nvidia platform. It was successful to build with Nvidia GPU Computing SDK 4.0 but I ran into several errors when I ran the demo. I am trying to fix them based on OpenCL SDK sam...

Cloth simulation

I made a cloth simulation using c++. It uses implicit backward euler integration and continuous collision detection for cloth-object and cloth self-collision. Strain limiting was used to simulate inextensible cloth. BVH/AABB was implemented to avoid n^2 collision checking. Rendering was done in Maya...
