Real-time Rendering of Forests Using Light Field Rendering and Lighting Algorithm

Abstract:

Real-time rendering and lighting of forests is a difficult problem in visual system. Due to uncorrelated of scene complexity, the Image-based rendering techniques have been widely used for the scene reconstruction. An iterative-casting algorithm based on Light Field Rendering (IBR) is put forward to solve the reconstruction pro- blem, and then realizes a real-time forests rendering with lighting effects. The experimental results show that this algorithm has combined the advantages of iterative and casting algorithms, gets a balance between efficiency and quality.
