抄録(英) This paper describes a rendering method that simultaneously renders both volumetric and polygonal objects, making it possible to render volumetric objects intersected by polygonal or volumetric objects in the same scheme. In the proposed method, a scene with volumes and polygons overlapping each other is rendered using a ray-volume buffer that stores the colors and transmittance of rays at each voxel. Polygons inserted in a volume are rendered by map- ping the ray-volume data as a 3D texture. The ray-volume buffer method treats volumetric objects as polygons with textures. Therefore, the method can be utilized using conventional graphics pipeline techniques. Another feature of the proposed method is that ray-volumes can be generated without considering the intersection of polygons or volumes. The method is expanded for perspective projection from the method of parallel projection proposed in the 2001 IEICE Society Conference. For the eye point to be able to enter a volume, an octahedral wave front is used instead of a plane wave front to generate a ray volume.
