User Manual 3.3 Infinite rectangle cone
De Wiki
Definition
The infinite rectangle cones (infinite pyramids) are defined in a 3D space by their origin, their axis, a local frame (giving the orientation of the rectangle) and the two half angles :
Implementation
The InfiniteRectangleCylinder object in the SIRIUS library implements the InfiniteCone Interface. Please refer to the Javadoc for a complete list of public methods.
Instantiation
The object is built from three vectors (Vector3D) and two doubles :
Vector3D originCone = new Vector3D(1.0, 1.0, 1.0); Vector3D axis = new Vector3D(2.0, 0.0, 0.0); Vector3D inputVectorU = new Vector3D(0.0, 1.0, 0.0); double angleU = FastMath.PI / 4.0; double angleV = FastMath.PI / 4.0; InfiniteRectangleCone cone = new InfiniteRectangleCone(originCone, axis, inputVectorU, angleU, angleV);
The local frame is built such as :
- The axis is the W vector
- U is orthogonal to W and its direction is defined by the 'input U vector"
- V completes the frame
Usage
Please refer to the [MAT_GEO_Home#HInteractions Interactions with other geometrical objects section] for methods inherited from the Shape interface.
