rblock.prin.axis.angle
Syntax
- v = rblock.prin.axis.angle(p) (3D ONLY)
Get the orientation of the principal axis. This is given in the axis-angle representation. This orientation cannot be reset.
Returns: v - rigid block orientation vector Arguments: p - rigid block pointer
Component Access
f = rblock.prin.axis.angle
(p)->x
- f = rblock.prin.axis.angle.x(p) (3D ONLY)
Get the \(x\)-component of the axis-angle orientation of the principal axis.
Returns: f - \(x\)-component of the rigid block orientation vector Arguments: p - rigid block pointer
Access other vector components (\(y\), \(z\) (3D ONLY)) by substituting the component name where \(x\) appears above. See Member Access Operator for information about accessing members from data types using ->
.
Deprecated Component Access
Component access by adding an optional integer in the function arguments (e.g., f = rblock.prin.axis.angle(p, 3)
) is deprecated. It remains available but will not be supported in future versions. See Component Access with Integers in FISH on the Deprecated Commands and FISH page for details.
