This class adds a pivot node that can serve as a pivot point for its children and allows for easy control over their transformation. It has two matrices: one sets the basis of rotation (the pivot point transformation matrix), and another one describes local transformation for children nodes relative to the pivot point.

NodePivot ClassThis class inherits from Node
NodePivot ()Create a pivot node (with the pivot and local transformation matrices equal to mat4_identity).
mat4 getLocalTransform ()Returns the current matrix used to control local transformations of the child nodes.
Return valueLocal transformation matrix.
mat4 getPivotTransform ()Returns the current transformation matrix used to control the basis of rotation of the child nodes (the pivot point transformation matrix).
Return valuePivot point matrix.
void setLocalTransform (mat4 transform)Sets a matrix that controls local transformations of the child nodes.
- mat4 transform - Local transformation matrix.
void setPivotTransform (mat4 transform)Sets a matrix that controls the basis of rotation of the child nodes (the pivot point transformation matrix).
- mat4 transform - Pivot point matrix.
