btVector3 myVec(1.0f, 2.0f, 3.0f);
btVector3 vec1(1.0f, 2.0f, 3.0f); btVector3 vec2(4.0f, 5.0f, 6.0f); btVector3 result = vec1 + vec2;
btVector3 vec1(1.0f, 2.0f, 3.0f); btVector3 vec2(4.0f, 5.0f, 6.0f); btVector3 result = vec1.cross(vec2);This computes the cross product of vec1 and vec2 and stores the result in result (resulting in a btVector3 with x=-3.0, y=6.0, and z=-3.0). The btVector3 class is part of the Bullet Physics library, which is an open-source physics engine for simulating rigid body dynamics in games and other interactive applications.
