User Manual 3.3 Plates : Différence entre versions

Version actuelle en date du 4 avril 2018 à 13:34

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.
