Abstract
Systems and methods for rendering three-dimensional images by instancing scene description data using a hierarchy are provided. A hierarchy is accessed. The hierarchy comprises a first node and an instance node. The first node is a predecessor to a subtree of one or more nodes and the first node is associated with a first scene description data object. The instance node is a leaf of the hierarchy. The instance node has a parent node and the instance node is associated with a second scene description data object. The parent node has successor nodes other than the instance node. An instancing instruction of the instance node is read. The instancing instruction comprises information identifying the first node. An instance of the subtree of one or more nodes is merged at a location in the hierarchy of the instance node. An image is rendered based on the merged instance of the subtree.
