Method Details

getBody1

Body getBody1()

Access the first body in the constraint. The constraint is unaffected.

Returns:

a new JVM object with the pre-existing native object assigned

getBody1PivotLocation

void getBody1PivotLocation(DoubleBuffer storeResult)

Copy the first body's pivot location. The constraint is unaffected.

Parameters:

storeResult - storage for the location in system coordinates (not null, modified)

getBody2

Body getBody2()

Access the 2nd body in the constraint. The constraint is unaffected.

Returns:

a new JVM object with the pre-existing native object assigned

getBody2PivotLocation

void getBody2PivotLocation(DoubleBuffer storeResult)

Copy the 2nd body's pivot location. The constraint is unaffected.

Parameters:

storeResult - storage for the location in system coordinates (not null, modified)

getConstraintToBody1Matrix

Mat44 getConstraintToBody1Matrix()

Calculate the coordinate transform from constraint space to body 1. The constraint is unaffected.

Returns:

a new transform matrix

getConstraintToBody2Matrix

Mat44 getConstraintToBody2Matrix()

Calculate the coordinate transform from constraint space to body 2. The constraint is unaffected.

Returns:

a new transform matrix
