Picture generator
专利汇可以提供Picture generator专利检索，专利查询，专利分析的服务。并且PURPOSE: To generate a picture with high picture quality by applying a ray tracing algorithm on shape data of three-dimensional shape in which all the boundary surfaces expressed according to a CSG solid model are formed in quadratic curved surfaces.
CONSTITUTION: Targeted three-dimensional shape is expressed as the shape data in all the boundary surfaces consist of the quadratic surfaces as the CSG model in a host computer 8. A quadratic surface separation means 2 inputs the shape data, and re-defines it to a set operation in which the basic shape of the quadratic surface is set as the basic shape. An intersection calculation means 3 finds the crossing area of a line of sight decided by a given visual point and each basic shape of each quadratic surface of each image element on a screen desired to display. A set operating means 4 performs the set operation between the crossing areas at every shape of obtained quadratic surfaces, and finds a visible point that is a point on the boundary surface of three- dimensional shape. A luminance calculation means 5 finds the luminance of an obtained visible point. And the picture is displayed on a graphic display 9 as the one of three-dimensional shape in which all the boundary surfaces are formed in the quadratic surfaces.
