geom.edge.dir

Syntax

v := geom.edge.dir(e)

Get the edge direction. The edge direction is defined the vector from node 1 to node 2. Its magnitude is the length from node 1 to node 2.

Returns:

v - direction vector

Arguments:

e - edge pointer

Component Access

f := geom.edge.dir (e)->x

f := geom.edge.dir.x(e)

Get the \(x\)-component of the edge direction. The edge direction is defined from node 1 to node 2.

Returns:

f - \(x\)-component of the direction vector

Arguments:

e - edge pointer

Access other vector components (\(y\), \(z\)) 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 (geom.edge.dir(e,<int>)) 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.

This is hidden. Added to include remaining vector component access functions for inline help.

f := geom.edge.dir.y(e)

f := geom.edge.dir.z(e)
