A regular tetrahedron.
PlatonicTetrahedron(L)
Parameters:
As for any other Form factor.
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:
Scattering by uncorrelated, oriented tetrahedra for horizontal incidence:

Introduced in BornAgain 1.20.
Name chosen to disambiguate from “Tetrahedron”, which up to BornAgain 1.19 stood for a trigonal pyramid (Pyramid3).
