For a diagram-like rendering in Open3d, I would like to use color per triangle. draw_geometries() is a useful function to get a quick overview of static geometries. If you are using Python you can either use LD_PRELOAD or in Python you can load the CPU libGL. read_triangle_mesh(filename, enable_post_processing=False, print_progress=False) #. depth_image = render. For customizing the rendering options, you will have to move to using Visualizer class directly which allows finer control on rendering and view control options. You need to either use LD_PRELOAD to make sure your CPU libGL. create_window() vis. vertex_colors ). Visualizer class methods. 0 to 1. Loads the indirect light. Open3D uses FLANN to build KDTrees for fast retrieval of nearest neighbors. This class allows to send data to an external Visualizer.
