hm_projectpointtosegmentwithangle

Finds the projection point to a specific point on a segment along a specific direction.

Syntax

hm_projectpointtosegmentwithangle px py pz sx sy sz ex ey ez angle unused1 unused2

Type

HyperMesh Tcl Query Command

Description

Finds the projection point to a specific point on a segment along a specific direction. The result is returned as the point on the straight line that runs from point (px, py, pz) in the calculated direction, and is the point closest to the straight line that runs through points (sx, sy, sz) and (ex, ey, ez).

Inputs

px, py, pz
The point.
sx, sy, sz
Beginning of the segment.
ex, ey, ez
End of the segment.
angle
The angle, in degrees, that defines the direction vector in the x-y plane. 0 corresponds to the x-direction and 90 corresponds to the y-direction.
unused1
Unused, but must be specified.
unused2
Unused, but must be specified.

Example

Find the projection of (0.0, 0.0, 0.0) to the segment defined by points (1.0, -1.0, 0.0) and (1.0, 1.0, 0.0) using an angle of 0 (x-direction):

hm_projectpointtosegmentwithangle 0.0 0.0 0.0 1.0 -1.0 0.0 1.0 1.0 0.0 0.0 0.0 0.0
  1.0 0.0 0.0

Errors

None.
