walltime (time.time()) seconds after epoch of event
  Shape:
     vertices: (B, N, 3). (batch, number_of_vertices, channels)

     colors: (B, N, 3). The values should lie in [0, 255] for type
     *uint8* or [0, 1] for type *float*.

     faces: (B, N, 3). The values should lie in [0,
     number_of_vertices] for type *uint8*.

  Examples:

     from torch.utils.tensorboard import SummaryWriter
     vertices_tensor = torch.as_tensor([
         [1, 1, 1],
         [-1, -1, 1],
         [1, -1, -1],
         [-1, 1, -1],
     ], dtype=torch.float).unsqueeze(0)
     colors_tensor = torch.as_tensor([
         [255, 0, 0],
         [0, 255, 0],
         [0, 0, 255],
         [255, 0, 255],
     ], dtype=torch.int).unsqueeze(0)
     faces_tensor = torch.as_tensor([
         [0, 2, 3],
         [0, 3, 1],
         [0, 1, 2],
         [1, 3, 2],
     ], dtype=torch.int).unsqueeze(0)
