Isotopic implicit surface meshing [PDF]
Proceedings of the thirty-sixth annual ACM symposium on Theory of computing, 2004 This paper algorithmically solves the problem of finding an approximating isotopic simplicial surface for a compact regular level set \([f=0]\) of a \(C^2\) function \(f\) defined in space. This topic is highly relevant for computing and visualization, unfortunately the authors mention that they have not yet implemented their algorithm.

The implicit equation of a canal surface [PDF]
Journal of Symbolic Computation, 2009 A canal surface is an envelope of a one parameter family of spheres. In this paper we present an efficient algorithm for computing the implicit equation of a canal surface generated by a rational family of spheres. By using Laguerre and Lie geometries, we relate the equation of the canal surface to the equation of a dual variety of a certain curve in 5-

Implicit meshes for surface reconstruction [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2006 Deformable 3D models can be represented either as traditional explicit surfaces, such as triangulated meshes, or as implicit surfaces. Explicit surfaces are widely accepted because they are simple to deform and render, but fitting them involves minimizing a nondifferentiable distance function.

Res-NeuS: Deep Residuals and Neural Implicit Surface Learning for Multi-View Reconstruction [PDF]
SensorsSurface reconstruction using neural networks has proven effective in reconstructing dense 3D surfaces through image-based neural rendering. Nevertheless, current methods are challenging when dealing with the intricate details of large-scale scenes.

Variational implicit surface meshing [PDF]
Computers & Graphics, 2009 In this paper, we propose a new algorithm to mesh implicit surfaces which produces meshes both with a good triangle aspect ratio as well as a good approximation quality. The number of vertices of the output mesh is defined by the end-user. For this goal, we perform a two-stage processing : an initialization step followed by an iterative optimization ...

Implicit-implicit and parametric-implicit surface intersections in Euclidean n-space
Acta et Commentationes Universitatis Tartuensis de Mathematica, 2023 In this paper, we study the intersection problem of two surfaces in which at least one surface is given by its implicit equation in Euclidean n-space. We first obtain the curvatures of the transversal intersection curve of two implicit surfaces. Later, the intersection problem is studied for a parametric surface and an implicit surface in n-dimensional

Neural Implicit Surface Evolution
2023 IEEE/CVF International Conference on Computer Vision (ICCV), 2023 This work investigates the use of smooth neural networks for modeling dynamic variations of implicit surfaces under the level set equation (LSE). For this, it extends the representation of neural implicit surfaces to the space-time $\mathbb{R}^3\times \mathbb{R}$, which opens up mechanisms for continuous geometric transformations.
