The Lightness Information Calculation Software On Three-Dimensional Object

Three-dimensional visualization technology is at a rapid pace, It is widely used, especially in the direction of the visualization simulation. This paper the first chapter briefly described on the research significance, research content and research methods on the lightness information calculation software on three-dimensional object. According to the software features, Chapter 2 introduced OpenGL development libraries and MFC development library's organizational structure and the methods of use, It also introduced the related background knowledge of light reflection and the illumination studies; Chapter 3 made the overall demand for software features, and made a analysis of that software specific module needs like:the framework of MFC, input/output module, display module, data calculation module; Chapter 4 importantly focused on the whole process of the software design, a specific module design and implementation process in the key technology, citing the main functional modules, such as framework of the display module and the key code, data file format of the data module, three-dimensional object coordinate transformation strategy, as well as the Z-Buffer hidden surface removal algorithm; In the end of the paper, through the software actual operation, Chapter 5 obtained visualizational results and the corresponding numerical information, and made a further request on the software.
