    • calculateTransforms

      public void calculateTransforms()

      Calculates the local and world transform of all IntNode instances in this model, recursively.

Then each IntNode.calculateWorldTransform() is calculated, based on the parent's world transform and the local transform of each IntNode. Finally, the animation bone matrices are updated accordingly.

      This method can be used to recalculate all transforms if any of the IntNode's local properties (translation, rotation, scale) was modified.
