摘要
The present invention discloses a view volume culling method using the least deviation spatial dichotomy. The method of the present invention comprises the steps of: determining the number of cells and dividing the world's XYZ axes by the minimum deviation spatial dichotomy; A second step of obtaining a repair vector for each plane constituting the reference visual space, obtaining a new repair vector by applying a viewpoint transformation to each repair vector, and then obtaining each plane equation of the new visible space; A third step of examining whether the cluster is contained in the visible space by applying 8 points of the minimum boundary value MBB to each plane equation of the visible space obtained in the second step; According to the result of applying the 8 points of the minimum boundary value (MBB) in the third step, if the cluster is nested in the visible space, the cluster is included in the display list. A fourth step of investigating and putting on the display list; And a fifth step of rendering all polygons in the display list of the fourth step.;Accordingly, the present invention reduces the memory usage and improves the rendering speed by performing 3D dynamic view volume culling after dividing the visible space using the minimum deviation spatial dichotomy.
