Reflecting surface design system, reflecting surface design method, recording medium, and computer program

摘要

A reflecting surface design system (50) has (1) first rendering means (54) for displaying a free-form surface (20) on which a plurality of segments (24), each of which is defined by a plurality of vertices (25₁ to 25₄), are formed, (2) reflection information specifying means (56) for specifying the vertex position and light reflecting direction for each of the plurality of vertices (25₁ to 25₄) that define one of the plurality of segments (24), and (3) surface calculation means (58) for calculating a surface (S) to be assigned to the one segment (24) on the basis of the vertex positions and light reflecting directions specified for the plurality of vertices (25₁ to 25₄) that define one segment (24), and the light source position, which is specified in advance.
