how to use it in realtime scenario not offline?

[lucasjinreal]

Hi, how to use it visualize human mesh regressed from SMPL realtime? Something just like opencv imshow in waitKey(0). It just show frame by frame with fastest render speed.

Does this lib can support this?

Currently this is meant to playback a sequence of already exiting meshes, not like imshow by opencv. But it would be possible I guess, here an example which displays a torus or box (alternating):

import time
import open3d as o3d

from mesh_sequence_player.MeshSequencePlayer import MeshSequencePlayer


def mesh_show(player: MeshSequencePlayer, geometry: o3d.geometry.Geometry3D, wait_time: float = 0.0):
    player.vis.clear_geometries()
    player.vis.add_geometry(geometry, reset_bounding_box=True)

    t = time.time()
    while time.time() - t < wait_time:
        player.vis.poll_events()
        time.sleep(0.01)


def main():
    player = MeshSequencePlayer()
    player.open()

    torus = o3d.geometry.TriangleMesh.create_torus()
    box = o3d.geometry.TriangleMesh.create_box()

    for i in range(20):
        geometry = torus if i % 2 == 0 else box
        mesh_show(player, geometry, 0.2)

    player.close()


if __name__ == "__main__":
    main()
