Method Detail

updateModelTransform

void updateModelTransform(Transform localTransform,
                          Joint parent)

Update the joint's transform in model space.

Parameters:

localTransform - the joint's local transform (not null, unaffected)

parent - the joint's parent, or null for a root joint

getOffsetTransform

void getOffsetTransform(Matrix4f outTransform,
                        Matrix4f inverseModelBindMatrix)

Determine the joint's skinning transform.

Parameters:

outTransform - storage for the result (modified if not null)

inverseModelBindMatrix - the joint's inverse model bind matrix (not null, unaffected)

applyBindPose

void applyBindPose(Transform localTransform,
                   Matrix4f inverseModelBindMatrix,
                   Joint parent)

Configure joint's local transform for bind pose.

Parameters:

localTransform - the joint's local transform (not null, unaffected)

inverseModelBindMatrix - the joint's inverse model bind matrix (not null, unaffected)

parent - the joint's parent, or null for a root joint

getModelTransform

Transform getModelTransform()

Determine the joint's transform in model space.

Returns:

a new instance or a pre-existing one
