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)¶: Initialize self. See help(type(self)) for accurate signature.

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 visiblity may not correspond with this value

property name¶: The name of the object

property time¶: The object’s timestamp

class Shader¶

Scene-level rendering options

Members:

STANDARD : Pixel colors from standard lighting model

UNLIT : Normals will be ignored (useful for point clouds)

NORMALS : Pixel colors correspond to surface normal

DEPTH : Pixel colors correspond to depth buffer value

DEPTH = Shader.DEPTH¶

STANDARD = Shader.STANDARD¶

UNLIT = Shader.UNLIT¶
