Illumination environment simulation system and method thereof

Abstract

The invention provides an illumination environment simulation system used for an electronic device, wherein the system comprises a triangular grid module, an illumination environment configuration module, a calculating module and a display module. The triangular grid module is used for reading three dimensional objects from a storage device connected with the electronic device and performing triangular grid processing on the three dimensional objects. The illumination environment configuration module is used for configuring an illumination environment for the three dimensional objects subsequent to the triangular grid processing, and the configuration comprises the steps of determining an illumination scope, a light source position, an illumination direction and a light source intensity parameter. The calculating module is used for determining the real display color of each triangle in dependence on the initial colors of the three dimensional objects, the included angles between light rays along the illumination direction and the normal vector of each triangle surface, and the distances between each triangle and the light source position. The display module is used for projecting the three dimensional objects to a display device connected with the electronic device for output in dependence on the coordinate and the real display color of each triangle on the three dimensional objects.

Description

technical field [0001] The invention relates to a computer aided design system and method, in particular to a lighting environment simulation system and method applied in the field of three-dimensional measurement. Background technique [0002] In a three-dimensional measurement system, if the object to be measured is not subjected to light treatment, the object to be measured cannot display a three-dimensional effect, but can only display a flat effect (such as Figure 11 shown), resulting in the inability to recognize the detailed features of the object. However, the existing auxiliary lighting system cannot reflect the characteristics of light source attenuation with distance, which leads to the unrealistic three-dimensional effect displayed by the object to be tested. Contents of the invention [0003] In view of the above, it is necessary to provide a lighting environment simulation system that can simulate the lighting effect of the object to be tested and render the...
