Crate subsphere

subsphere

Sphere tessellation toolkit

This crate provides a general, easy-to-use API for working with tessellated spheres, i.e. spheres whose surface is partitioned into polygonal cells. It includes implementations for a variety of such tessellations.

Features

• Implicit Representation: Instead of storing geometry data directly, the tessellations, and the elements within them, are represented implicitly. They are compact zero-allocation Copy types that can be used to generate geometry on the fly. This lets you work with massive tessellations using very little memory.

• Versatility: This crate allows you to explore a huge variety of tessellations, all sharing a common API. There’s a bunch of adjustable parameters and you’re free to mix-and-match topologies and projections to tune the tessellation to your needs.

• Spherical Geometry: In the world of subsphere, there is only one geometric space: the sphere. All objects follow the contours of the sphere, and all calculations correctly account for this.
