Hello, I do not understand the order of operations of a SAP. This is how I understand it: 1.) Add an object(s) to the SAP. This computes the AABB of the rigidbody, add the min and max endpoints to each dynamic array (one for each axis), and adds the box/AABB to the array of boxes. This step does no ...

After reading the SAP document, I've got a rather trivial question. Would storing the AABB boxes in a STL vector be appropriate? Is there any pitfalls I should look out for if I were to use a STL vector?

Edit - Nevermind

Thank, this helps very much! I will give this a read. I've done a little more research, and I've found a paper on the method I-Collide uses, a paper on SWIFT's method, Erleben's paper on BVH "An Introduction to Approximatting heterogeneous Bounding Volume Hierarchies", and the papers of St...

Hello, I'm considering different methods for doing broad phase collision detection. At the moment, the approach proposed in "Optimized Spatial Hashing for Collision Detection of Deformable Objects" seems to be the most appealing. This is what's used in the Chipmunk engine. Other possibilit...

Hi,

as I side note your server is really slow. I can't download the paper.

How do the methods of Jan Bender compare to Erin Catto's SI method? Are there any obvious advantages or disadvantages between the two?

Hi, after much work the first version of my impulse-based dynamic simulation library called IBDS is online: http://www.impulse-based.de The impulse-based dynamic simulation is a new method for the simulation of articulated rigid body systems that I have developed during my PhD. It can handle all ki...

Thanks for the input, it's really appreciated! So, Impulse based dynamics it is. Besides Erin Catto's slides (which I can't view properly because I'm on a Mac, and NeoOffice doesn't display the power point slides correctly) are there any papers on SI? If not, I guess I'll just follow Iterative Dynam...

Thanks! So I guess the paper to read is the one Erin Catto wrote in 2005: Iterative Dynamics with Temporal Coherence.

Just out of curiosity, what's wrong with the Verlet technique presented by Rick Baltman and Ron Radeztsky Jr.?

Hi, I'm looking to implement my first rigid body engine, and I'm undecided which technique to use. The one's I'm considering are the approaches presented in: Advance Character Physics, by Thomas Jakobsen Verlet Integration and Constraints in a Six Degree of Freedom Rigid Body Physics Simulation, by ...
