Detail enhanced versatile optical model for hybrid rendering of volume data
摘要
Abstract
Versatile optical model can be seen as an extension to the traditional model, which can characterize both the behavior of individual particles and the collective effect of particles in homogeneous regions.But, this hybrid model will not only be able to reduce the illumination effect, but also need to adjust a number of parameters, and it is necessary to manually adjust the number of parameters for light enhancement.In order to solve the problem of weak light and adjustment parameter, we propose a detail enhanced versatile optical model for hybrid rendering of volume data and introduce the concept of curvature in hybrid model to enhance the render result according to the corresponding relationship between the curvature and intensity of illumination and improved Phong model.Finally, the experimental results of several groups of data show that the method can not only improve the detail expression of versatile optical model and better identify the shape of the object, but also reduce the manual operation of adjusting the parameters.关键词
