building_blocks.edge.direction
Syntax
- v = building_blocks.edge.direction(ep)
Get edge direction. The return value is a 3D vector from start point to the end point of the edge.
Returns: v - direction of the edge (3D vector) Arguments: ep - edge pointer
Component Access
f = building_blocks.edge.direction
(ep)->x
- f = building_blocks.edge.direction.x(ep)
Get the \(x\)-component of edge direction. The return value is a 3D vector from start point to the end point of the edge.
Returns: f - \(x\)-component of the direction of the edge (3D vector) Arguments: ep - 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 (building_blocks.edge.direction(ep,<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.
