Witrynametric surfaces and implicit surfaces. A parametric surface [1, 2] is usually given by a function f (s, t) that maps some 2-dimensional (maybe non-planar) parameter domain Ω into 3-space while an implicit surface typically comes as the zero-level isosurface of a 3-dimensional scalar field f (x, y, z). Implicit surface models are popular since Witryna27 mar 2024 · 3 code implementations in PyTorch. Implicit representations of 3D objects have recently achieved impressive results on learning-based 3D reconstruction tasks.
