Member Data Documentation

wVector forceOnJoint

protected

The force applied to this joint.

Definition at line 82 of file phyfixed.h.

Referenced by PhyFixed::getForceOnJoint(), and PhyFixed::PhyFixed().

wMatrix globalMatrixChild

protected

Global Matrix respect to Child.

This represent the local frame of joint in global coordinate starting from localMatrixParent representation.

Referenced by PhyFixed::updateJointInfo().

wMatrix globalMatrixParent

mutableprotected

Global Matrix respect to Parent.

This represent the local frame of joint in global coordinate starting from localMatrixParent representation.

Note: The differences between globalMatrixParent and globalMatrixChild are due to numerical error on joint solver of physic engine used.
