ladybug_display.geometry3d.cylinder module

A cylinder that can be displayed in 3D space.

class ladybug_display.geometry3d.cylinder.DisplayCylinder(geometry, color=None, display_mode='Surface')[source]

Bases: _SingleColorModeBase3D

ToString()
duplicate()

Get a copy of this object.

classmethod from_dict(data)[source]

Initialize a DisplayCylinder from a dictionary.

Parameters

data – A dictionary representation of an DisplayCylinder 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 DisplayCylinder as a dictionary.

property area

Get the surface area of the cylinder.

property axis

Get a Vector3D for the axis of the cylinder.

property center

Get a Point3D for the center of the bottom of the cylinder.

property color

Get or set a color for this object.

property display_mode

Get or set text to indicate the display mode.

property geometry

Get a ladybug_geometry object.

property height

Get a number for the height of the cylinder.

property radius

Get the radius of the cylinder.

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 volume

Get the volume of the cylinder.
