irtk.transform.lookat

irtk.transform.lookat(origin: List[float] | torch.Tensor, target: List[float] | torch.Tensor, up: List[float] | torch.Tensor) → torch.Tensor

Compute a ‘look-at’ transformation matrix.

Parameters:

  • origin (Union[List[float], torch.Tensor]) – The position of the camera.

  • target (Union[List[float], torch.Tensor]) – The point the camera is looking at.

  • up (Union[List[float], torch.Tensor]) – The up vector of the camera.

Returns:

A 4x4 transformation matrix.

Return type:

torch.Tensor
