Voir la source de User Manual 3.4.1 Infinite right circular cone

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

[[File:cone.PNG|center]]

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

====Instantiation====
The object is built from two vectors (Vector3D) and a double : 

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