VOXEL-BASED INDOOR RECONSTRUCTION FROM HOLOLENS TRIANGLE MESHES [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 Current mobile augmented reality devices are often equipped with range sensors. The Microsoft HoloLens for instance is equipped with a Time-of-Flight (ToF) range camera providing coarse triangle meshes that can be used in custom applications.

Static 3D triangle mesh compression overview [PDF]
2008 15th IEEE International Conference on Image Processing, 2008 3D triangle meshes are extremely used to model discrete surfaces, and almost always represented with two tables: one for geometry and another for connectivity. While the raw size of a triangle mesh is of around 200 bits per vertex, by coding cleverly (and separately) those two distinct kinds of information it is possible to achieve compression ratios ...

Semantic-guided 3D building reconstruction from triangle meshes
International Journal of Applied Earth Observations and Geoinformation, 2023 Planar primitives tend to be incorrectly detected or incomplete in complex scenes where adhesions exist between different objects, resulting in topology errors in the reconstructed models. We propose a semantic-guided building reconstruction method known

Geometric modeling based on triangle meshes [PDF]
ACM SIGGRAPH 2006 Courses on - SIGGRAPH '06, 2006 In the last years triangle meshes have become increasingly popular and are nowad ays intensively used in many different areas of computer graphics and geometry p rocessing. In classical CAGD irregular triangle meshes developed into a valuable alternative to traditional spline surfaces, since their conceptual simplicity a llows for more flexible and ...
