GPU-accelerated multi-valued solid voxelization by slice functions in real time

Abstract

This paper presents a GPU-accelerated slice-independent solid voxelization approach that utilizes a dynamic slice function mechanism and masking techniques to significantly improve solid voxelization speed in real time as well as create various multi-valued solid volumetric models with different slice functions. In particular, by dynamically applying different slice functions, any surface-closed geometric model can be voxelized into a solid volumetric representation with any kind of interior materials, such as rainbow, marble, wood, translucent jade, etc. In this paper, the design of the dynamic slice function, the principle and algorithm of solid slice creation, the algorithm of real-time solid voxelization, and GPU-based acceleration techniques will be discussed in detail. The algorithms introduced in this paper are easy to implement and convenient to integrate into many applications, such as volume modeling, collision detection, medical simulation, volume animation, and computer art. The experimental results and data analysis for the complex objects demonstrate the effectiveness, flexibility, and diversity of this approach.
