the transformation matrix for the node and its hierarchy
the child nodes of the current node
a sphere that bounds the current surface and its entire hierarchy; if no bound is given, the naive bound will be calculated by combining the bounding spheres of the current surface and its hierarchy
Transforms the current node, left-multiplying its transformation matrix by another matrix.
Transforms the current node, left-multiplying its transformation matrix by another matrix.
the new transform to add (by left-multiplication)
the transformed node
The node's child nodes, transformed using the current transformation matrix.
The node's child nodes, transformed using the current transformation matrix. Each new matrix is the child node's transformation matrix left-multiplied by the current (parent) matrix.
the transformed child nodes
The node's surface, transformed using the current transformation matrix.
The node's surface, transformed using the current transformation matrix.
the transformed surface
Represents a node with no surface, along with any potential child nodes in its hierarchy.
