::hwat::math::GetVector

Finds the i, j, and k components of a vector given the coordinates of the start and end point.

Syntax

::hwat::math::GetVector {startpnt} {endpnt}

Arguments

startpnt
Tcl list of x, y, and z coordinates of the tail node of the vector.
endpnt
Tcl list of x, y, and z coordinates of the tip node of the vector.

Returns

Success
Tcl list of the i, j and k components of the resultant vector
Failure
{}

Example

::hwat::math::GetVector [list 0.0 0.0 0.0] [list 10.0 8.5 7.0]

Comments

This is an N-dimensional operation. Both lists must be the same length, and the return list will also be the same length.
