Construction and Realistic Rendering of Scenes with Highly Complex Plants

Realistic rendering of complex natural scenes is a challenging research topic in computer graphics. Plant objects such as trees and grasses play an important role in the construction of virtual scenes. Plant objects are diversified to few classic types with variable complex structures and geometric shapes. Due to the complexity of types, realistic modeling and rendering of such a natural scene are usually costly and time consuming. To tackle the problem, polygons, texels, and volumetric texture are employed as effective tools to construct and render the classic types of plant objects based on type features. The method proposed in the paper simplifies the complexity and eliminates the aliasing of visual effects. The experiments show the feasibility of generating realistic images of natural plant scenes using hybrid modeling and rendering techniques employed in this paper.
