A Survey of Volumetric Illumination Techniques

for Interactive Volume Rendering

体可视化中的光照计算技术-Interactive volume rendering in its standard formulation has become an increasingly important tool in many

application domains. In recent years several advanced volumetric illumination techniques to be used in interactive

scenarios have been proposed. These techniques claim to have perceptual benefits as well as being capable of

producing more realistic volume rendered images. Naturally, they cover a wide spectrum of illumination effects,

including varying shading and scattering effects. In this survey, we review and classify the existing techniques for

advanced volumetric illumination. The classification will be conducted based on their technical realization, their

performance behavior as well as their perceptual capabilities. Based on the limitations revealed in this review, we

will define future challenges in the area of interactive advanced volumetric illumination.
