The keeper's note
Speeds up global illumination rendering by discriminating which virtual objects need a full versus primitive render pass.
Abstract
There is provided a system including a hardware processor, a memory, and an illumination rendering unit including a virtual object discrimination module stored in the memory. The hardware processor is configured to execute the illumination rendering unit to perform a first, primitive render ofan illumination of a scene including multiple virtual objects, and to determine a score for each of the virtual objects corresponding to its respective contribution to the illumination of the scene. The hardware processor is also configured to execute the illumination rendering unit to identify one or more of the virtual objects as disregardable based on their respective scores, and to perform a second render of the illumination of the scene while disregarding presence of the identified one or more virtual objects as disregardable inthe scene.
Background
BRIEFDESCRIPTION OF THE DRAWINGS(1) FIG. 1 shows a diagram of one exemplary implementation of a global illumination system configured to perform virtual object discrimination for fast global illumination rendering;(2) FIG. 2 shows a diagram of a virtual environment depicting interactions of rays utilized in a global illumination process with virtual objects within the virtual environment, according to one implementation;(3) FIG. 3 is a flowchart presenting an exemplary method for performing virtual object discrimination for fast global illumination rendering;(4) FIG. 4 is a diagram depicting virtual object discrimination for fast global illumination rendering using discrimination criteria set by a user of a global illumination system, according to one implementation; and(5) FIG. 5 is a diagram depictingvirtual object discrimination for fast global illumination rendering using discriminationcriteria set automatically by a global illumination system, according to one implementation.DETAILED DESCRIPTION(6) The following description contains specific information pertaining to implementations in the present disclosure. One skilled in the art will recognize that the present disclosure may be implemented in a manner different from that specifically discussed herein. The drawings in the present application and their accompanying detailed description are directed to merely exemplary implementations. Unless noted otherwise, likeor corresponding elements among the figures may be ind
Claims
