PlatonicTetrahedron

A regular tetrahedron.

Constructor

PlatonicTetrahedron(L)

Parameters:

  • L, length of the edge

Usage

As for any other Form factor.

Implementation

Class PlatonicTetrahedron inherits from the interface class IFormFactor .

Form factor computation is based on the generic form factor of a polyhedron provided by libformfactor .

Volume has been validated against $$ V= \dfrac{\sqrt{2}}{12}L^3. $$

More general:

  • Pyramid3, if not regular and/or truncated.

Example

Scattering by uncorrelated, oriented tetrahedra for horizontal incidence:

History

Introduced in BornAgain 1.20.

Name chosen to disambiguate from “Tetrahedron”, which up to BornAgain 1.19 stood for a trigonal pyramid (Pyramid3).
