open3d.t.io.read_point_cloud#

open3d.t.io.read_point_cloud(filename: os.PathLike, format: str = 'auto', remove_nan_points: bool = False, remove_infinite_points: bool = False, print_progress: bool = False) → open3d.t.geometry.PointCloud#

Read a tensor open3d.t.geometry.PointCloud from file.

For 3D Gaussian splat data (.ply / .splat with the usual attributes):

  • In-memory ``scale`` on the returned point cloud is always linear (axis lengths), which matches the Filament / rendering path.

  • PLY files follow the common convention of storing log-scale per axis; the reader applies exp so the tensor attribute scale is linear.

  • SPLAT files store linear scales already; no conversion is applied.

When writing PLY from a Gaussian splat cloud, write_point_cloud converts scale back to log-space for the same file convention.

Parameters:

  • filename (os.PathLike) – Path to file.

  • format (str, optional, default='auto') – The format of the input file. When not specified or set as auto, the format is inferred from file extension name.

  • remove_nan_points (bool, optional, default=False) – If true, all points that include a NaN are removed from the PointCloud.

  • remove_infinite_points (bool, optional, default=False) – If true, all points that include an infinite value are removed from the PointCloud.

  • print_progress (bool, optional, default=False) – If set to true a progress bar is visualized in the console.

Returns:

open3d.t.geometry.PointCloud
