PlanarSurface.normal_at
- PlanarSurface.normal_at(u=None, v=None, world=True)[source]
Construct the normal at a point on the planar surface.
- Parameters:
- ufloat, optional
The first parameter. The parameter is optional, because the normal is the same everywhere.
- vfloat, optional
The second parameter. The parameter is optional, because the normal is the same everywhere.
- Returns:
compas.geometry.VectorThe normal vector.
