Bas-relief generation from point clouds based on normal space compression with real-time adjustment on CPU

This paper presents a bas-relief generation algorithm from scattered point cloud directly. Compared with the popular gradient domain methods for mesh surface, this takes normal vectors as operation object, making it independent of topology connection, thus more suitable clouds and easier to implement. By constructing linear equations height using solution strategy subspace, can adjustment effect in real-time relying on computing power consumer CPU only. In addition, we also propose an iterative generate model specified height. The experimental results indicate that our provides unified generating different types good saturation rich details.
