Combined with the radiosity intensity of diffusely reflecting surfaces, the improved ray tracing method is reversely employed to analyze the apparent spectral emissivity of a body of semi transparent medium having some diffuse surfaces.

Based on the reflective and refractive phenomena of translucent objects, this paper proposes an algorithm to recover the material properties of the objects under complex environment illumination, where refractive index and the BRTDF model both are considered in the rendering process.

This paper presents a new fast algorithm,based on pre-computed light transport,for rendering translucent objects under all-frequency and complex illumination represented as a high-resolution environment map.

A ray split-off and tracing approach is presented to analyze the apparent spectral reflecting performance of a semitransparent fluid layer with undulant surface.

The effect of particle scattering on the absorptive characteristics of a semitransparent fluid layer is investigated by the Monte Carlo method.

In order to efficiently reconstruct 3D medical image and clearly display the detailed information of inner structures and the inner hidden interfaces between different mediums,an improved volume rendering optical model(IVROM) for translucent volume rendering is proposed,which can be easily realized on a general PC.
