hm_getlinetangentatcoordinate
Returns the closest point, the components of the tangent vector and the angle between the tangent vector and the z-axis at the point on the line closest to the input coordinates.
Syntax
hm_getlinetangentatcoordinate line_id x y z
Type
HyperMesh Tcl Query Command
Description
Returns the closest point, components of the tangent vector and the angle between the tangent vector and the z-axis at the point on the line closest to the input coordinates.. The first 3 return values are the closest point coordinates, the next 3 are the tangent vector components, and the last return value is the angle.
Inputs
- line_id
- The ID of the line.
- x, y, z
- The (x,y,z) coordinates of the point.
Example
To get the components of the tangent vector and the angle between the tangent vector and the z-axis nearest the coordinates (100,50,25) for the line with ID 341:
foreach {x y z tg_x tg_y tg_z ang}[hm_getlinetangentatcoordinate 341 100 50 25{}
Errors
if { [ catch {command_name...} ] } {
# Handle error
}
