Hi, I put latest CVS source here to someone have problem with CVS or compiling the source. The zip includes: + Source from CVS . ODE with stepFast by Dave. . Opcode + VC.NET 2003 workspace + VC6 workspace http://www.coderfarm.com/pubs/Physics/ODE_CVS_Win32.zip Enjoy! Hint: Let's try to spawn about 100s box or ball to see that ODE is really rock now.
