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 k

Adaptive approximation of signed distance fields through piecewise continuous interpolation

Autor: Pujol Puig, Eduard, Chica Calaf, Antonio

In this paper, we present an adaptive structure to represent a signed distance field through trilinear or tricubic interpolation of values, and derivatives, that allows for fast querying of the field. We also provide a method to decide when to subdiv

Efficient discretization of signed distance fields

Autor: Pujol Puig, Eduard

A Signed distance field (SDF) is an implicit function that returns the distance to the surface of a volume given a point in the space. The sign of the field indicates if the point is inside or outside the volume. These fields are usually used to acce

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. We sugg
