森林场景的钢笔风格化实时绘制技术*

在大型复杂场景绘制关键技术研究项目中，通过把复杂场景绘制与调度技术，如Slicing、MMI、层次图像缓存和基本布告板等大场景实时加速绘制技术的多层次绘制方法，融合到非真实感绘制技术中，以提高系统面对复杂场景的实时绘制能力。最后实现了对森林等大型场景的钢笔画绘制，借助非真实感绘制技术中基于图像空间的生成方法，利用各种不同大小及形状的笔画实现了艺术化森林场景实时交互绘制。提出了植物多层次钢笔风格化渲染算法。

Rendering forest scenes in real-time based on pen-and-ink style

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.
