摘要
在计算机图形学中,渲染一直是核心方向,对于真实感渲染,其最终目标就是正确地计算场景中的全局光照.针对渲染对象的不同,所采取的渲染方法也有所不同,大体上可以分为表面渲染和体渲染.通过对物理的蒙特卡罗体渲染方法的整理,描述了在经典参与介质中如何采用蒙特卡罗方法进行渲染,介绍了近年来兴起的针对非经典参与介质的研究,对近年来渲染的高级方法做了总结,阐述了目前渲染方法所存在的问题以及未来可能的研究方向.
Abstract
In computer graphics,rendering has always been a core direction.For realistic rendering,the ultimate goal is to correctly calculate the global illumination in the scene.Different rendering methods are adopted depending on the objects be-ing rendered,but they can generally be divided into surface rendering and volume rendering.This paper provides an overview of physically-based Monte Carlo volume rendering methods.First,it describes how Monte Carlo methods are used to render classical participating media,and then introduces research on non-classical participating media that has emerged in recent years.It also summarizes advanced rendering methods in recent years,and finally discusses the current issues in rendering methods and potential future research directions.
