ToString()
duplicate()

Get a copy of this object.

classmethod from_dict(data)[source]

Initialize a DisplayMesh3D from a dictionary.

Parameters

data – A dictionary representation of an DisplayMesh3D object.

move(moving_vec)

Move this geometry along a vector.

Parameters

moving_vec – A ladybug_geometry Vector with the direction and distance to move the geometry.

reflect(plane)

Reflect this geometry across a plane.

Parameters

plane – A ladybug_geometry Plane across which the object will be reflected.

rotate(axis, angle, origin)

Rotate this geometry by a certain angle around an axis and origin.

Parameters
  • axis – A ladybug_geometry Vector3D axis representing the axis of rotation.

  • angle – An angle for rotation in degrees.

  • origin – A ladybug_geometry Point3D for the origin around which the object will be rotated.

rotate_xy(angle, origin)

Rotate this geometry counterclockwise in the world XY plane by an angle.

Parameters
  • angle – An angle in degrees.

  • origin – A ladybug_geometry Point3D for the origin around which the object will be rotated.

scale(factor, origin=None)

Scale this geometry by a factor from an origin point.

Parameters
  • factor – A number representing how much the object should be scaled.

  • origin – A ladybug_geometry Point representing the origin from which to scale. If None, it will be scaled from the World origin.

to_dict()[source]

Return DisplayMesh3D as a dictionary.

property area

Get the area of the mesh.

property center

Get a Point3D for the center of the bounding box around the object.

property color

Get or set a color for this object.

property display_mode

Get or set text to indicate the display mode.

property face_areas

Get a tuple with the area of each face in the mesh.

property face_centroids

Get a tuple with the centroid of each face in the mesh.

property face_normals

Get a tuple of Vector3D objects for all face normals.

property faces

Get a tuple of all faces in the mesh.

property geometry

Get a ladybug_geometry object.

property max

Get a Point3D for the maximum of the bounding box around the object.

property min

Get a Point3D for the minimum of the bounding box around the object.

property user_data

Get or set an optional dictionary for additional meta data for this object.

This will be None until it has been set. All keys and values of this dictionary should be of a standard Python type to ensure correct serialization of the object to/from JSON (eg. str, float, int, list, dict)

property vertex_normals

Get a tuple of Vector3D objects for all vertex normals.

property vertices

Get a tuple of vertices in the mesh.
