Member Function Documentation

◆ AddGeometry()

bool open3d::visualization::Visualizer::AddGeometry ( std::shared_ptr< const geometry::Geometry > geometry_ptr )

virtual

Function to add geometry to the scene and create corresponding shaders

After calling this function, the Visualizer owns the geometry object.
This function MUST be called after CreateVisualizerWindow().
This function returns FALSE when the geometry is of an unsupported type.
If an added geometry is changed, the behavior of Visualizer is undefined. Programmers are responsible for calling UpdateGeometry() to notify the Visualizer that the geometry has been changed and the Visualizer should be updated accordingly.

Reimplemented in open3d::visualization::VisualizerWithEditing.
