- lsdo_genie.utils.normal_approx.midpoint_normal_approx(vertices: numpy.ndarray)
Approximate an arbitrary closed polygon by using the midpoints of the edges formed by an input set of vertices Normal direction is determined by the direction of the points given in the input: Clockwise : normals point outwards Counter-Clockwise : normals point inwards
- Parameters:
- verticesnp.ndarray(num_pts,2)
The input points
- Returns:
- midpoints: np.ndarray(num_pts,2)
Midpoints between input points
- normalsnp.ndarray(num_pts,2)
Normal vectors at the midpoints
- lsdo_genie.utils.normal_approx.vertex_normal_approx(vertices: numpy.ndarray)
A quick way to approximate the normal vectors from an arbitrary closed polygon. Normals are an average between the 2 edge normals adjacent to a point and follow a covention: Clockwise : normals point outwards Counter-Clockwise : normals point inwards
- Parameters:
- verticesnp.ndarray(num_pts,2)
The input points
- Returns:
- normalsnp.ndarray(num_pts,2)
Approximate normal vectors at the input points
