3Subject: [ODE] dRay class
4Date: Thu, 25 Jul 2002 13:05:28 +0200
5
6Yesterday and today i've written a dRay class. It interacts with dPlane,
7dSphere, dBox and dCCylinder. It does not generate full contact information.
8It only generates the pos member. I dont think its useful to anyone to go
9through hoops and find a reasonable normal and penetration depth, as i dont
10think anyone will want to use it for dynamics. Just for CD.
11
12It should compile in single and double precision mode, and should be
13platform independant. I hope.
14
15The next Tri-Collider release using Opcode 1.1 will also implement a ray
16collision function along with some other not too interesting improvements.
