# ::hwat::math::PointOnVector

Finds a point on a vector at a given distance from the tail (starting point) of the vector. If the distance is given in percentage, it finds a point at percentage of the total vector length.

## Syntax

::hwat::math::PointOnVector {startpnt} {endpnt} distance

## 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.
distance
Distance to find the point at.
Default = 50%.

## Returns

Success
Tcl list of the x, y and z coordinates of the point on the vector.
Failure
{}

## Example

set newLoc [PointOnVector [list 0.0 0.0 0.0] [list 10.0 8.5 7.0] 20 ]
