User Manual 3.3 Right circular cone
De Wiki
Definition
The right circular cones are defined in a 3D space by their origin, their axis, height and the half angle :
Implementation
The RightCircularCone object in the SIRIUS library implements the Cone Interface. Please refer to the Javadoc for a complete list of public methods.
Instantiation
The object is built from two vectors (Vector3D) and two doubles :
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);
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.
