User Manual 3.4.1 Plates
Definition
The plates are rectangles defined in a 3D space by their centre and a local orthogonal frame (U, V, W).
The normalized U vector defines the "length" direction, the normalized V vector defines the "width" direction.
The four corners are named C1, C2, C3 and C4 in the following order :
Implementation
The Plate object implements the SolidShape interface. Please refer to the Plate javadoc for a complete list of public methods.
Instantiation
The plate object is built from a centre (Vector3D), two vectors (Vector3D) to describe its orientation, and two dimensions :
Vector3D center = new Vector3D(1.0, 1.0, 1.0); Vector3D uVector = new Vector3D(1.0, 1.0, 0.0); Vector3D inputvVector = new Vector3D(-5.0, 1.0, 0.0); Plate plate = new Plate(center, uVector, inputvVector, 4.0, 2.0);
The local frame of the plate is built from the two orientation vector :
- U is the first once normalized (uVector)
- V is the vector normal to U in plane define by the two given vectors, in the direction of the second one (positive dot product with "input vVector")
Usage
Please refer to the [MAT_GEO_Home#HInteractions Interactions with other geometrical objects section] for methods inherited from the Shape interface.
