In applications such as computational swept volume light painting, real-time contour rendering is essential to ensure shape fidelity. However, there is, at yet, no real-time and scalable solution for slicing a model in arbitrary direction. We propose a new slicing method by organizing the triangular mesh into Octree data structure. The approach can significantly reduce the computational time and improve the performance of real-time rendering. The data structure is invariant to the slicing direction, thus constructing the Octree is a one-time, offline pre-process.
