nsfera

nsfera is a theoretical concept and software framework for representing and processing n-dimensional spheres, generalizing classical sphere geometry to higher dimensions and enabling practical computations in computer graphics, geometry processing, and data visualization.

The name combines the letter n, indicating dimensionality, with sfera, derived from sphere in romance languages. In mathematics, the related idea is the n-sphere, but nsfera emphasizes an integrated approach to data structures, algorithms, and practical implementations.

Mathematically, an nsfera can be viewed as a manifold equipped with a metric induced by an embedding in ambient Euclidean space. It supports parameterizations such as generalized spherical coordinates, and is designed to support tessellation and discretization for numerical computation.

Representations include parametric, implicit, and mesh-based forms. Core operations encompass geodesic computation, projection between representations, sampling and refinement, curvature estimation, and distance and intersection queries. The framework emphasizes stability under perturbation and efficient memory usage for large-scale applications.

Applications span computer graphics, scientific visualization, virtual reality, and high-dimensional data analysis where spherical topology informs the geometry. Various experimental libraries and research prototypes implement nsfera constructs, often for integration with established geometry kernels and rendering pipelines.
