Due to the wide diffusion of 3D printing technologies, geometric algorithms for Additive
Manufacturing are being invented at an impressive speed. Each single step along the …

Nowadays, digital 3D models are in widespread and ubiquitous use, and each specific
application dealing with 3D geometry has its own quality requirements that restrict the class …

Several RGB-D datasets have been publicized over the past few years for facilitating
research in computer vision and robotics. However, the lack of comprehensive and fine …

We present an Adaptive Octree-based Convolutional Neural Network (Adaptive O-CNN) for
efficient 3D shape encoding and decoding. Different from volumetric-based or octree-based …

Applying CNNs to extrinsic surface representation such as volumetric grids [Qi et al. 2016b]
or depth map projections on extrinsic 2D cameras [Wei et al. 2016] requires working with 3D …

We introduce a novel approach that reconstructs 3D urban scenes in the form of levels of
detail (LODs). Starting from raw data sets such as surface meshes generated by multi-view …

When designing novel algorithms for geometric processing and analysis, researchers often
assume that the input conforms to several requirements. On the other hand, polygon meshes …

Solid shapes in computer graphics are often represented with boundary descriptions, eg
triangle meshes, but animation, physically-based simulation, and geometry processing are …

Geospatial object segmentation, a fundamental Earth vision task, always suffers from scale
variation, the larger intra-class variance of background, and foreground-background …

This paper presents a novel hole-filling algorithm that can fill arbitrary holes in triangular
mesh models. First, the advancing front mesh technique is used to cover the hole with newly …
