Model.hm_gettgofpointsonline

Model.hm_gettgofpointsonline(line_entity, u_parameter_list)

Returns the line coordinates and tangents at each of the given line u parameters.

Parameters:

• line_entity (Entity) – The object describing the line entity to query.

• u_parameter_list (hwString) – The list of u parameter values to query.

Returns:

• hwReturnStatus - Status object

• HmQueryResultList - Result list object containing HmQueryResult objects with the following output data:

  • tangentVectorComponents (numpy.ndarray) - Tangent vector components for each parameter u

  • pointCoordinates (numpy.ndarray) - Point coordinates for each parameter u

Example

Get the tangent value to line with ID 2619 at parameters 0 , 0.3 , 0.6 and 1

import hm
import hm.entities as ent

model = hm.Model()

ulist = "0 0.3 0.6 1"

_, resultlist = model.hm_gettgofpointsonline(
    line_entity=ent.Line(model, 2619), u_parameter_list=ulist
)

for u, result in zip(ulist.split(" "), resultlist):
    print(
        f"For u={u} the tangent vector components are:", result.tangentVectorComponents
    )
    print(f"For u={u} the point coordinates are:", result.pointCoordinates)
