Embodiment Construction

[0057] Now, the present invention will be described with reference to preferred embodiments. This is not intended to limit the scope of the invention, but to illustrate the invention.

[0058] At the beginning of describing the embodiment of the present invention, its basic concept will be described. Draw 3D objects using 3D world coordinates. In order to represent such an object on the screen, it is necessary to specify a view volume (view volume) in the world coordinate system, and perform clipping of the object to be projected on the display screen according to this view volume. As one of projection directions for displaying 3D objects on a two-dimensional display, there is a perspective projection method. For perspective projection methods, the vertex of the view volume is usually the view point, and the view volume is a semi-infinite pyramid defined by directions and angles from the view point. In the present invention, the object space is partitioned into subspaces us...

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.

Description

technical field [0001] The present invention relates to an image processing technology, in particular to an image processing method and device for rendering a three-dimensional object to be displayed on a two-dimensional screen. Background technique [0002] In applications such as computer games and simulations that use many 3D graphics, high-speed computer graphics (CG) processing is required due to movement of a user's point of view viewing a 3D object and the user's movement of the 3D object. Specifically, high-speed rendering processing is necessary every time an object or viewpoint moves. In this processing, the world coordinates of the object are transformed into two-dimensional coordinates by perspective transformation. Based on this position information and the texture characteristics of the object's surface, such as color and pattern, color information is determined pixel by pixel through representation processing, which is then written into frame buffer memory fo...
