Interactive shape modeling using a skeleton-mesh co-representation
ACM Transactions on Graphics (TOG), Volume 33, Issue 4Article No.: 132, Pages 1–10https://doi.org/10.1145/2601097.2601226We introduce the Polar-Annular Mesh representation (PAM). A PAM is a mesh-skeleton co-representation designed for the modeling of 3D organic, articulated shapes. A PAM represents a manifold mesh as a partition of polar (triangle fans) and annular (rings ...

Facetons: face primitives with adaptive bounds for building 3D architectural models in virtual environment
VRST '13: Proceedings of the 19th ACM Symposium on Virtual Reality Software and TechnologyPages 77–82https://doi.org/10.1145/2503713.2503718We present faceton, a geometric modeling primitive designed for building architectural models, using a six degrees of freedom (DoF) input device in a virtual environment (VE). A faceton is given as an oriented point floating in the air and defines a ...

Efficient evaluation of continuous signed distance to a polygonal mesh
SCCG '12: Proceedings of the 28th Spring Conference on Computer GraphicsPages 101–108https://doi.org/10.1145/2448531.2448544An efficient representation of a polygonal mesh by a signed continuous distance field is the main focus of this work. We compare different approaches to implementing such a representation and choose the most efficient one. Several optimizations to the ...

Data hiding on 3D polygonal meshes
MM&Sec '04: Proceedings of the 2004 workshop on Multimedia and securityPages 68–74https://doi.org/10.1145/1022431.1022445This paper presents a high-capacity method to embed information into the geometry of a 3D polygonal mesh. The method extends a previously reported work, to which several improvements have been brought. By construction, the new embedding algorithm is ...

Retrieving 3D shapes based on their appearance
MIR '03: Proceedings of the 5th ACM SIGMM international workshop on Multimedia information retrievalPages 39–45https://doi.org/10.1145/973264.973272In this paper, we propose an algorithm for shape-similarity comparison and retrieval of 3D shapes defined as polygon soup. One of the issues in comparing 3D shapes is the diversity of shape representations used to represent these "3D" shapes. While a ...

Efficient compression of non-manifold polygonal meshes
We present a method for compressing non-manifold polygonal meshes, i.e. polygonal meshes with singularities, which occur very frequently in the real-world. Most efficient polygonal compression methods currently available are restricted to a manifold ...
