Definition |
An instance of this DRM class specifies the radius and orientation of the major and minor axes that specify an elliptical cylindrical volume. The volume centre is specified by the aggregate of the <DRM Cylindrical Volume Extent> instance and is at the mid point of all three axes. The radii are specified relative to the volume centre. The <DRM Reference Vector> components specify the elliptic cross section axes. The first <DRM Reference Vector> component specifies the major axis direction with vector_type = MAJOR_AXIS. The second <DRM Reference Vector> component specifies the minor axis direction with vector_type = MINOR_AXIS. The cross product of the major axis with the minor axis defines a plane that orients the cylinder. Half the length of the cylinder extends perpendicular to one side of this plane, half on the other side. The major_axis_radius field is specified in metres. The minor_axis_radius field is specified in metres. The cylinder_length field is specified in metres. |
