This means you can select the entire mesh and convert triangles that already form. This tool can be applied on a selection of multiple triangles. This tool converts the selected triangles into quads by taking adjacent triangles and removing the shared edge to create a quad, based on a threshold.

Dakolic (grape) August 19, 2020, 8:25pm 8.Meshes with an emphasis on watertight meshes. But that might work for low poly- or for reducing a couple thousand triangles, not 290K. Those loops will be removed from the mesh, causing distortions in the mesh. His mesh has 300k triangles, which means that Blender must delete atleast 290k triangles from somewhere, its not magic.

ReturnsInt export ( file_obj = None, file_type = None, ** kwargs ) Export the current pointcloud to a file object.If file_obj is a filename, file will be written there.:param file_obj: str, file name where to save the pointcloudNone, if you would like this function to return the export blob ParametersFile_type ( str) – Which file type to export as.If file name is passed this is not required property extents The size of the axis aligned bounds ReturnsExtents – Edge length of axis aligned bounding box Return typeAre there any vertices defined or not. ReturnsCopied – Copy of current point cloud Return typeGet a CRC hash of the current vertices.

PointCloud ( vertices, colors = None, metadata = None, ** kwargs ) Hold 3D points in an object which can be visualizedIn a scene. Meshes need vertex positions and triangles, usually UV coordinates.Provide a fully featured Trimesh object which allows for easy manipulationAnd analysis, in the style of the Polygon object in the Shapely library.

ReturnsCamera_transform – Camera transform in the base frame Return typeReturn the center of the bounding box for the scene.
