hexasphere
Library for subdividing shapes, such as an icosahedron. This provides abstractions for almost anything to be possible, however there are many predetermined shapes.
In the case of the icosphere:
Geometry:
This starts off with an icoashedron, and then proceeds to subdivide it. The subdivided points form the dual to a goldberg polyhedron. In essence, each point on this sphere is either a hexagon or a pentagon.
Interpolation:
Points are interpolated using the geometric slerp
function to preserve their accuracy.
Features
- Base shapes
- Icosahedron
- Tetrahedron
- Triangle
- Square
- Cube
- Interpolation functions
- Spherical interpolation
- Linear interpolation
- Normalized linear interpolation
- Basic optimizations for
p == 0.5
in interpolation. - An adjacency (neighbour) map which can be generated from the indices that this library creates.
A few more optimizations are coming, along with more options for generation:
- Remove nested triangle layers by placing them into their own
Vec
. - Allow interpolation functions to have access to state. (This would permit certain things such as sampling noise as part of the generation).
