Python ShapeAnalysis_Surface.ValueOfUV Examples

Example #1

 def point_to_parameter(self, pt):
     '''
     returns the uv value of a point on a surface
     @param pt:
     '''
     sas = ShapeAnalysis_Surface(self.surface_handle)
     uv = sas.ValueOfUV(pt, self.tolerance)
     return uv.Coord()

Example #2

File: core_geometry_geomplate.py Project: tnakaicode/pythonocct-demos

def uv_from_projected_point_on_face(face, pt):
    '''
    returns the uv coordinate from a projected point on a face
    '''
    srf = BRep_Tool().Surface(face)
    sas = ShapeAnalysis_Surface(srf)
    uv = sas.ValueOfUV(pt, 1e-2)
    print('distance ', sas.Value(uv).Distance(pt))
    return uv.Coord()
