Collision detection should be enabled with two modes: "hit-and-stop" and "hit-to-push": [Sketch](http://sketch.paperjs.org/#V/0.11.8/S/nVdNb+M2EP0rAx/WEiLTjje5yPUW6KK3pl1sFughCgJaGlvayKRAUnGCbP77Dqlv2…

最近在看box2d的源码，看得好累。发现box2d的碰撞检测不止用到了SAT（分离轴）算法，还有**GJK算法**和V-clip算法（连google都找不到的冷门算法，不知道具体原理）。box2d貌似把3种算法糅合起来了，根本看不懂。
不过看到GJK时，我上网了解了一下，感觉眼前一亮，因为看到一种跟分离轴思路完全不同的碰撞检测算法还是很开心的。和SAT一样，GJK算法也只对凸多边形有…

# modules needed:
## renderer
- 2d/3d
- rendering to show it to the auditory
- and to have visual "tests"; with 3d it'll be a powerful visual testing tool

Hi,
This is a question rather than an issue.
I am trying to improve the performance of libccd support functions in ODE a bit by removing the unneeded transformations between world space and local sp…

Looking at "TKraftShapeType" i am missing Cone and Cylinder.
Are you looking forward to implement these two ?
If not i can / will try to implement them in the way you did TKraftShapeBox using a …

The current collision detection system uses a simple distance-based approach. We should implement a more sophisticated algorithm to improve accuracy and performance for complex scenarios.
Proposed …
