Light Base on OpenGL
This is a new attempt as the lighting part of the rendering system in my engine program. I have built several common lights in the rendering system. Because it is implemented with OpenGL3.0 and is based on a rasterized rendering pipeline. Therefore, there are still some defects in global lighting.

3D model retrieval based on hand drawn sketch
With the rapid development of CPU and GPU, 3D models are not only becoming more and more complex and rich in details, but also widely used in animation, machinery, medical and other fields. The number of 3D models is also increasing. The classification and retrieval of 3D models has become an important research direction. Although many scholars have done different researches on 3D model retrieval technology and proposed many different model retrieval algorithms, there are still many problems to be solved.
