Abstract
According to embodiments of the invention, a data structure may be created which may be used by both a ray tracing unit and by a rendering engine. The data structure may have an initial or upper portion representing bounding volumes which partition a three-dimensional scene and a second or lower portion representing objects within the three-dimensional scene. The integrated acceleration data structure may be used by a rendering engine to render a two-dimensional image from a three-dimensional scene, and by a ray tracing unit to perform intersection tests.
