Rendering forest scenes in real-time based on pen-and-ink style
森林场景的钢笔风格化实时绘制技术*

In the project that studies the big and complex environments render technique, this paper combined the complex scenes rendering and scheduling technique to non-photo-realistic rendering, ie.And merged the multi-layered drawing into which the Slicing, MMI(multi-mesh imposter), hierarchical image caching and billboard technique. In this way, got the real-time rendering capability of system enhancement. Studied the automatic generation of pen-and-ink drawing systematically in NPR using strokes with different size and shape, with the method of image-based generation. And proposed the multi-layered vegetation rendering with the pen-and-ink style for accelerated drawing of complex environments, ie. forest scene.
