An HSM(Hierarchy Structure Memory)(106) stores space subdivision and bounding volume hierarchy structure information and bounding hierarchy structure information. A VP(Virtual Pager)(110) receives the geometry triangle data, the space subdivision and bounding volume hierarchy structure information, and the bounding hierarchy structure information from the HSM and the GDM, rearranges geometry triangle data according to the last termination node, and generates triangle data. A VPM(Virtual Paged Memory)(112) receives the data rearranged according to triangles, forms paged memories corresponding to the respective triangles according to a paged memory type, and stores the triangle data of the VP according to pages. A VPC(Virtual Paged Cache)(114) performs a pipe line process of page data, and previously stores a paged memory for checking a collision among paged memories of the VPM. An RTCDP(Ray Triangle Collision Detection Pipe)(116) receives the paged memory stored in the VPC and the ray bundle of the RBM, and checks a collision of the ray and the triangle. An output memory(118) stores an output for a triangle in which the collision occurs with the respective rays processed in the RTCDP.
