◆ pad0

btGeneric6DofSpringConstraint __pad0__

Generic 6 DOF constraint that allows to set spring motors to any translational and rotational DOF.

DOF index used in enableSpring() and setStiffness() means: 0 : translation X 1 : translation Y 2 : translation Z 3 : rotation X (3rd Euler rotational around new position of X axis, range [-PI+epsilon, PI-epsilon] ) 4 : rotation Y (2nd Euler rotational around new position of Y axis, range [-PI/2+epsilon, PI/2-epsilon] ) 5 : rotation Z (1st Euler rotational around Z axis, range [-PI+epsilon, PI-epsilon] )
