In this case, we need to create a dummy interface. How do I generate a partial view of a mesh as a point cloud in Python? Not the answer you're looking for? # Color Map Optimization for 3D Reconstruction with Consumer Depth Cameras, o3d.visualization.draw_geometries([mesh]), intel-isl / Open3D / examples / Python / Basic / mesh_properties.py, AoLyu / 3D-Object-Reconstruction-with-RealSense-D435 / Realtime_registrition_of_two_cam / Realtime.py, intel-isl / Open3D / examples / Python / Basic / mesh_sampling.py, 'Uniform sampling can yield clusters of points on the surface', 'Poisson disk sampling can evenly distributes the points on the surface. When the computer has no active network interfaces (e.g. Currently I am using Python, part of my code is as follows: When I use draw_geometries or draw_geometries_with_animation_callback, it seems they could not display a list of point clouds: TypeError: draw_geometries(): incompatible function arguments. This owns the menubar, windows, and event loop. draw_geometries visualizes the point cloud. origin point set at (-2, -2, -2). For instance, the - key reduces the size of the points (surfels). To programmatically destroy the window do window.close().Usage: create_window(title, width, height, x, y, flags). This function produces exactly the same functionality of the convenient function draw_geometries. This function simply reads a point cloud and calls draw_geometries_with_editing. Ensure -DBUILD_GUI=ON and -DBUILD_WEBRTC=ON are set in the CMake config See Customized platforms: Standalone/Jupyter mode client (web browser). To draw lines, it is necessary to define a LineSet with a set of points and a set of edges (pairs of point indices). Calling the following code. Therefore we would like to use a GUI Framework like PYQT and integrate the Open3D vizualizer window, so that both are wrapped in a single application.
