method and apparatus for optimizing hardware graphics acceleration board operation for real time rendering

摘要

The present invention relates to a system and method for operation optimization in a hardware graphics accelerator for real-time rendering, which optimizes operation number or sequence in the hardware graphics accelerator so as to improve the display speed of three-dimensional objects on a computer screen when the three-dimensional objects are displayed with the hardware graphics accelerator. The invention enables a high screen display speed by analyzing material properties of the 3-D objects prior to screen display and grouping triangles composing the 3-D objects according to the same material property to produce triangle groups as many as the material properties; sorting and managing the triangles in each of the groups according to the distance from a camera; and extracting one triangle most distanced from the camera from the each of the groups at the point of screen display and finally selecting one triangle most distanced from the extracted triangles and outputting the same, in which the triangles are so controlled that another triangle extracted from the same group as the selected triangle is continuously outputted unless the another triangle does not overlap with the triangle extracted from other group even after the selected triangle is displayed. Effective display state is maintained due to distance control from the camera and the state variation is minimized so that a high-speed display is enabled using the hardware graphics accelerator.
