Disclosed is an object defined in a three-dimensional virtual space makes it possible to perform the intersection test ellipsoid and view frustum body in culling be ellipsoidal.
A is a cross-determining technique in which each viewing cone it is determined whether intersects the object arranged in the three-dimensional virtual space in a tile-based culling, when the shape of the object is ellipsoidal for the entire space with the origin of the viewpoint ellipsoid performs expansion processing for expanding and contracting a space view frustum body and ellipsoid are arranged so as to be spherical, coordinate information of the spheres after stretch-processing and post-stretch treatment and to perform intersection determination of a sphere and view frustum body by using the coordinate information of Mikiritai.
