Johnson's algorithm computes the barycentric coordinates of the point closest to the origin of a simplex. Ericsson's suggested alternative to Johnson does not compute the barycentric coordinates IIRC. and The paper makes no mention of barycentric coordinates. What Ericson suggests, is to use vorono...

Hi, It all depends, what you are looking for, but I would recommend to try to hook-up the Bullet collision detection to ODE. Perhaps look at the module overview, or doxygen: DOXYGEN: http://www.continuousphysics.com/Bullet/BulletFull/html/annotated.html MODULE OVERVIEW: http://www.continuousphysics....

This one comes with visual studio 6,7 and 8 project files, as well as the demos. Should compile out of the box. If not, please let me know.

>You dispach the contacts in the collision library - that means you apply the impulses directly there. The separation is there: There is no rigidbody class in the collision detection, so no impulses can be applied there. Can you verify this ? The Bullet folder contains only collision detection, Bull...

This version uses the Bullet's own penalty method solver, and its GJK convex collision detection: It has the option to show the lifetime of contactpoints, and to toggle deactivation (c and d keys) http://207.234.235.180/ftp/pub/test/BulletGjkPhysicsDemo.zip This one uses the gameblender renderer: ht...

It is on 'dynamic geometric deformation as result of collisions', an implementation of which was done using Ogre3D as the display engine. http://www.ogre3d.org/phpBB2/viewtopic.php?t=11962&postdays=0&postorder=asc&start=0 Here is a preprint of the paper http://pwp.netcabo.pt/0175938601/o...

Chris Hecker had a GDC lecture about this, with some good references. Also he is happy to share his lemke code if you mail him. Objective Caml code. Chris mailed me and hinted that he is going to update his website 'soon'. From his gdc lecture: OMatrix, free trial contains lemke http://www.omatrix.c...

Next version 1.4 will probably contain physics export!

There are a lot of ways to break a rigidbody dynamics system, and Bullet is no exception. It will require a lot of tweaking to get things right, both for the dynamics system writer and for the user. Unfortunately small object sizes, lack of friction and damping, too much collision detail, large mass...

Most modern physics middleware are adding the option for continuous collision detection. CCD can help to avoid missing collision detection. It can be enabled either for all objects, or just for objects that are critical for the gameplay (player, player car, hand grenades). Perhaps in your engine the...

I replied earlier, but changed my mind, deleted it and decided to reformulate it. Hi, this is my first post. So let me introduce myself. I'm John McCutchan, I go to McMaster University in Hamilton, Ontario. I have been interested in 3D Physics engines for about a year now. Last year I wrote a rigid ...
