::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.
::hwat::math::PointOnVector {startpnt} {endpnt} distance
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 a Tcl list of the x, y and z coordinates of the point on the vector if successful, "{}" otherwise.
set newLoc [PointOnVector [list 0.0 0.0 0.0] [list 10.0 8.5 7.0] 20 ]
This is an N-dimensional operation. Both lists must be the same length and the return list will also be the same length as the input lists.
