Hi NGD 1.5 has just been released. New features: - New collision callback capabilities - Inertia and volume calculation - Point-Convex Hull and Hull-Hull distance calculation(very useful for AI) - Center-of-mass offset on the fly - Collision primitives transformations on the fly - Much more stable and powerful Custom Joint - allows arbitrary user-passed constrains and direct passing Jacobian rows(also spring-damper DOFs) - Revamped vehicle container - stable at 60fps, supersampled, no more jiterring problems. - Improved collision detection speed, up to several times in some cases(with dense tri meshes and complex hulls) - Platform architecture control - Many redy to use custom joints - Win32, MacOS and Linux(in several days) support

Moving to "Your Announcements," consistent with gamedev forum policy.
