Rendering System for Large-Scale Grass

Grass is one of the nature elements that is difficult to render in real-time due to its geometric complexity and the large coverage area. Realistic simulation of grass is one of the challenging topics in computer graphics. In this paper, a rendering system for large-scale grass is presented and implemented. Not only does this system provide high efficient scene rendering method for grass, but also it supports extendable architecture. We discussed the general architecture of this system and the key techniques for modeling and rendering of large-scale grass. Experimental results show that this system can produce realistic grass and has interactive frame rate.
