Well...i assume that you are talking about the javax.vecmath Vector3f then? In that case, the actual conversion is sv.x=v3f.x, sv.y=v3f.y and sv.z=v3f.z. However, coordinate systems of the actual vectors may differ (http://www.jpct.net/wiki/index.php/Coordinate_system). The most usual form is that the coordinate system of jPCT is rotated 90° around the x-axis compared to others. If that is the case, just negate y and z to convert between the two. jumong
