A Novel Method for Virtual Environment Generation Based on Non-photorealistic Rendering
一种基于NPR的虚拟环境生成方法

Aesthetic virtual environment cannot be satisfied if using traditional image based rendering. By introducing non-photorealistic rendering into the Virtual Reality, this paper presents a novel method for aesthetic virtual environment generation. First, structure tensor is calculated to characterize local structure of image.Then, total variation partial difference equation is imposed for smoothing vector field. Based on this we use line integral convolution for guiding the stroke to generate image with fluctuant sense. Last, merging with 3D scene, roam-able aesthetic virtual environment can be generated. Experiment Results show that we can simulate fluctuant sense image, and thus special style of aesthetic virtual environment can be satisfied using our algorithm.
