Title:
METHOD AND APPARATUS FOR RENDERING THREE-DIMENSIONAL OBJETS
Document Type and Number:
WIPO Patent Application WO2004023399
Kind Code:
A3
Abstract:
An image processing apparatus (120) for performing rendering processing of three-dimensional objects is provided. An object storage unit (52) stores the three-dimensional data of the object and the array data of B-box which encloses the spatial region which the object occupies. A grouping unit (44) reads in the B-box array from the object storage unit (52), does grouping of multiple B-boxes into groups based on the object characteristics and level of detail information. A rendering processing unit (46) derives a brick in which there are B-boxes belonging to the same group and generates image data by doing rendering processing independently by brick to be stored in an image storage unit (54). A consolidation unit (48) consolidates the image data per brick stored in the image storage unit (54) and generates the final output image data to be displayed.
