Real-time shadow rendering in Vega scene simulation
Vega视景仿真中的实时阴影绘制

Real-time shadow rendering seldom appears in most scene simulation systems developed in Vega or other high level APIs.A method integrating shadow generation into Vega scenes was presented.Shadow algorithms in virtual environment and the extended interface provided by Vega were studied first,and then shadow mapping algorithm was chosen to generate shadow in Vega scene.The algorithm was implemented in OpenGL,then shadow rendering was integrated into 3D scenes using Vega's callback mechanism,and it makes the final results more realistic.
