摘要
Abstract
In the volume rendering process in which the equal step sampling is used when the display is not ideal, a large number of samples will increase when a sample step is reduced. It increases the data calculation in the volume rendering process greatly. For this problem, this paper proposes a method based on Monte-Carlo integration to achieve real time ray casting volume rendering. The paper uses the Monte-Carlo integration method to solve the integral equation in the light propagation. The experimental results show that when the premise of visual effect is almost the same, the method used in this paper would improve the efficiency in drawing more than ten frames.关键词
