walberla::geometry::Ellipsoid Class Reference

Detailed Description

Class representing an Ellipsoid in 3D.

Implements body concept, i.e. a fastOverlapCheck and a contains() function, which can be used to initialize fields. For details about the body concept see BodyOverlapFunctions.h

#include <Ellipsoid.h>

Constructor & Destructor Documentation

Ellipsoid()

walberla::geometry::Ellipsoid::Ellipsoid ( const Vector3< real_t > & midpoint, Vector3< real_t > axis1, Vector3< real_t > axis2, const Vector3< real_t > & radii )

explicit

Ellipsoid constructor.

Parameters

midpoint	midpoint of the ellipsoid
axis1	the first semi-axis of the ellipsoid ( associated with radius1 ) not required to be normalized, is normalized internally
axis2	second semi-axis (must not be parallel to axis1 ) should ideally be perpendicular to axis1 if not perpendicular, axis2 is made perpendicular to axis1 using one Gram-Schmitt step. The third semi-axis is computed as cross-product of axis1 and axis2
radii	the length of the semi axes
