Claim 12:
13. A non-transitory computer-readable storage medium having stored thereon computer readable instructions which, when executed by a processor, cause the processor to perform a method of rendering an image of a 3-D scene using ray tracing, the method comprising:
identifying an intersection between a ray and implicitly-defined geometry located in a 3-D scene, a location of the intersection expressed in a reference coordinate system for a bounding element that encloses the implicitly-defined geometry;
identifying an intersection of the ray with explicitly-defined geometry, a location of the intersection with explicitly-defined geometry being expressed in a global coordinate system; and
transforming either the location of the intersection with implicitly-defined geometry into the global coordinate system or the location of the intersection with explicitly-defined geometry into the referenced coordinate system, and comparing which of the intersections is closer to an origin of the ray;
wherein a result of said comparing which of the intersections is closer to an origin of the ray is used for rendering an image of the scene.
