Abstract:The Simulation drilling system provides a good service for the enterprises and the emergency departments at present. However, it still has quite a few drawbacks. Such as the lack of modern graphic pipeline support, the excessive computation of scene rendering on the condition of multiple lights, the poor rendering effects caused by that it cannot make full use of hardware etc. In order to solve those problems, this paper is designed and implemented with a deferred shading pipeline for simulation drilling system. This pipeline is based on the Blinn-Phong lighting model, which builds a compressed G-buffer layout and uses Light volume to model the light source. The final experiment indicates that under the multiple lights circumstances, the deferred shading expressed in this paper will be more efficient than the conventional forward shading.
