Abstract

Abstract

In order to obtain arbitrary planes of industrial CT volume data, a new fast section display algorithm based on 3D texture mapping was proposed. Firstly, industrial CT serial images were loaded in sequence and stored as volume data. Secondly, these data were defined as 3D texture after transforming by the transfer function. Then according to the plane parameters given by the user, the cutting polygon on the section plane was calculated, which made a preparation for the calculation of corresponding 3D texture coordinates. Finally, a section plane was obtained by mapping conducted. The main feature of this method is that it completes sampling and interpolation with texture mapping supported by the graphics processor. The experimental results show the presented algorithm could capture the slice data in arbitrary direction，and also satisfy the speed requirements of the Human-Computer Interaction.
