We propose a novel neural architecture for representing 3D surfaces, which harnesses two complementary shape representations: (i) an explicit representation via an atlas, i.e., embeddings of 2D domains into 3D; (ii) an implicit-function representation, i.e., a scalar function over the 3D volume, with its levels …

WitrynaAn implicit surface is defined by the equation \(f(\vec p) = iso\) with \(f\) actually defining a volume and is known under many names: scalar / potential / (signed) distance / density field. \(f\) can be defined with mathematical equations (sphere, cylinder, ellipse...) but the same way we have triangle meshes to represent a surface we can ... Witryna26 lis 2024 · Gradient-SDF: A Semi-Implicit Surface Representation for 3D Reconstruction. We present Gradient-SDF, a novel representation for 3D geometry that combines the advantages of implict and explicit representations. By storing at every voxel both the signed distance field as well as its gradient vector field, we enhance the …
Witryna27 kwi 2014 · We present a novel framework to compute geodesics on implicit surfaces and point clouds. Our framework consists of three parts, particle based approximate geodesics on implicit surfaces, Cartesian grid based approximate geodesics on point clouds, and geodesic correction. The first two parts can effectively generate …
