==== Definition ====

The right circular cones are defined in a 3D space by their origin, their axis, height and the half angle :

[[File:coneFinite.PNG|center]]

==== Implementation ====

The RightCircularCone object in the SIRIUS library implements the [MAT_GEO_ConeInterface Cone Interface]. Please refer to the [{{JavaDoc3.4.1}}/org/apache/commons/math3/geometry/euclidean/threed/RightCircularCone.html Javadoc] for a complete list of public methods.

==== Instantiation====

The object is built from two vectors (Vector3D) and two doubles :

<syntaxhighlight lang="java">
Vector3D originCone = new Vector3D(1.0, 1.0, 1.0);
Vector3D direction = new Vector3D(2.0, 0.0, 0.0);
double angle = FastMath.PI / 4.0;
double height = 5.0;
RightCircularCone cone = new RightCircularCone(originCone, axis, angle, height);
</syntaxhighlight>

The local frame is built such as :

* The axis is the W vector
* U and V are two orthogonal and normalised vectors to complete the frame

==== Usage ====

Please refer to the [MAT_GEO_Home#HInteractions Interactions with other geometrical objects section] for methods inherited from the Shape interface.
