release目录，其下有一可执行文件及其所须的位图及模型文件。-Including drawing a straight line, anti-aliasing straight line, circle, ellipse, rectangle, draw polygon, rectangle fill, polygon fill, 3D transformations, lighting, textures and so on. Because energy is limited, not to make any comments on the original code. Simplify programming for consideration, in many places specified constant, without making common treatment. Extracted to establish gui16 directory under their original code and project files. In gui16 established under the release directory, under which an executable file and the required bitmap and the model file.
