Remove the homogeneous bottom row from [..., 4, 4] pose matrices.

Construct lookat view matrix.

log to the requested format outputs :param args: the arguments to log

New pose using average position, z-axis, and up vector of input poses.

Creates videos out of the images saved to disk.

view: view camera depth: depthmap

Estimate the bounding sphere given camera pose

Perform TSDF fusion given a fixed depth range, used in the paper. voxel_size: the voxel size of the volume sdf_trunc

Experimental features, extracting meshes from unbounded scenes, not fully test across datasets. return o3d.mesh

Generate an elliptical render path based on the given poses.
