====Definition====
Disks are used for the [[MAT_GEO_RectangleCone|finite rectangle cones]].

[[File:disk.PNG|center]]

====Implementation====
The Disk object implements the [{{JavaDoc4.0}}/fr/cnes/sirius/patrius/math/geometry/euclidean/threed/SolidShape.html SolidShape interface] and extends the
[{{JavaDoc4.0}}/fr/cnes/sirius/patrius/math/geometry/euclidean/threed/AbstractEllipse.html Disk and abstract ellipse] class. Please refer to the [{{JavaDoc4.0}}/fr/cnes/sirius/patrius/math/geometry/euclidean/threed/package-summary.html Disk and AbstractEllipse javadoc] for a complete list of public methods.

====Instantiation====
The disk object is built from a centre (Vector3D), one vector representing the normal to the disk surface (Vector3D) and one radius :

<syntaxhighlight lang="java">
Vector3D center = new Vector3D(1.0, 1.0, 1.0);
Vector3D normal = new Vector3D(1.0, 1.0, 0.0);
double radius = 1;
Disk disk = new Disk(center, normal, radius);
</syntaxhighlight>

The local frame of the disk is built from the normal vector.

====Usage====
See [{{JavaDoc4.0}}/fr/cnes/sirius/patrius/math/geometry/euclidean/threed/AbstractEllipse.html abstract ellipse] and [[MAT_GEO_Home#HInteractions|interactions with geometrical objects]].
