Detailed Description

PhySlider class.

Definition at line 37 of file physlider.h.

Constructor & Destructor Documentation

PhySlider	(	const wVector &	axis,
		PhyObject *	parent,
		PhyObject *	child,
		bool	cp = `true`
	)

Constructor.

Parameters

axis	is the axis on which objects slide (respect to parent object frame)
parent	is the parent object.
child	is the child object
cp	is internal; ignore it The local frame is translated toward centre and the Z axis is aligned with axis in order to create the complete local coordinate frame of this joint

Member Data Documentation

wVector forceOnJoint

protected

The force applied to this joint.

Definition at line 91 of file physlider.h.

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

wMatrix globalMatrixChild

protected

Global Matrix respect to Child.

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

Definition at line 87 of file physlider.h.

Referenced by PhySlider::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. Note: This is mutable because it can be changed in the centre() const function

Definition at line 81 of file physlider.h.

Referenced by PhySlider::centre(), PhySlider::PhySlider(), and PhySlider::updateJointInfo().

wMatrix localMatrixChild

protected

Local frame of the joint respect to the child matrix.

Definition at line 69 of file physlider.h.

Referenced by PhySlider::PhySlider(), and PhySlider::updateJointInfo().

wMatrix localMatrixParent

protected

Local frame of the joint respect to the parent matrix.

This matrix is calculated from Axis and Centre passed to constructor Axis will became the Z-axis of local frame (axis of rotation), and the two others axes are calculated in order to get a local frame Centre is copied as it is into w_pos of localMatrixParent
