bool open3d::visualization::Visualizer::PollEvents | ( | ) |
Function to process the event queue and return if the window is closed.
Use this function if you want to manage the while loop yourself. This function will NOT block the thread. Thus it is suitable for computation heavy task behind the scene.
|

Function to register a callback function for animation.
The callback function returns if UpdateGeometry() needs to be run.
callback_func | The call back function. |
|
virtual |
Function to remove geometry from the scene.
geometry_ptr | The Geometry object. |
|
protectedvirtual |
Function to do the main rendering The function first sets view point, then draw geometry (pointclouds and meshes individually).
void open3d::visualization::Visualizer::ResetViewPoint | ( | bool | reset_bounding_box = false | ) |
Function to reset view point.
void open3d::visualization::Visualizer::Run | ( | ) |
Function to activate the window.
This function will block the current thread until the window is closed.
|
virtual |
Functions to change between fullscreen and windowed modes.
|
virtual |
|
virtual |
Function to update geometry.
This function must be called when geometry has been changed. Otherwise the behavior of Visualizer is undefined. If called without an argument, updates all geometries, otherwise only updates the geometry specified.
Reimplemented in open3d::visualization::VisualizerWithVertexSelection.
|
virtual |
Function to inform render needed to be updated.
|
