    Abstract: PURPOSE: A method for extracting a cross test area in ray tracing and a rendering device thereof are provided to increase the operation speed of ray tracing by removing a unnecessary cross test area for secondary ray generated from light reflected from an object according to a form of the object. CONSTITUTION: All object data inputted from ray tracing are transmitted to a geometry engine unit(20) in which a plurality of geometry engine are connected in parallel from a head processor(10). Each geometry engine performs box bounding and projection of objects inputted. The geometry engines provide information determined by features of the objects including bounding box coordinates to a ROI(Ray Object Intersect) information generator(40). A raster engine(30) refers area information of a bounding box reflected to an image screen and performs shading processing of the object data. In addition, the raster engine(30) generates videos rendered. The ROI information generator(40) receives object information to be rendered. In addition, the ROI information generator(40) selects an object and stores an identification number of the object in a ROI buffer(50).

    Abstract: PURPOSE: A volume rendering apparatus and a method for the same are provided to reduce a bottle neck effect of a calculating process and memory access by using parallel processing method and a pile-line method. CONSTITUTION: The device comprise eight sub-volume processing portions(100-800) and a combination portion(900). Each sub-volume processing portion comprises a sub-volume memory(20), a ray plane processor(30), a ray plane memory(40), a ray segment generator(50), a FIFO(60), a ray segment compositor(70), a ray compositor(80), and a look-up table(90). The apparatus processes volume data to an X-axis, a Y-axis, and a Z-axis by using the eight sub-volume processing portions(100-800).
