open3d.visualization.O3DVisualizer#

class open3d.visualization.O3DVisualizer#

Visualization object used by draw()

class DrawObject#

Information about an object that is drawn. Do not modify this, it can lead to unexpected results.

__init__(*args, **kwargs)#

property geometry#: The geometry. Modifying this will not result in any visible change. Use remove_geometry() and then add_geometry()to change the geometry

property group#: The group that the object belongs to

property is_visible#: True if the object is checked in the list. If the object’s group is unchecked or an animation is playing, the object’s visibility may not correspond with this value

property name#: The name of the object

property time#: The object’s timestamp

class Shader#

The callback will be called as callback(o3dvis, time_since_last_tick, total_elapsed_since_animation_started). Note that this is a low-level callback.

set_on_close(self: open3d.cpu.pybind.visualization.O3DVisualizer, callback: Callable[[], bool]) → None#: Sets a callback that will be called when the window is closed. The callback is given no arguments and should return True to continue closing the window or False to cancel the close
