irtk.transform.perspective

irtk.transform.perspective(fov: float, aspect_ratio: float, near: float = 1e-06, far: float = 10000000.0) → torch.Tensor

Compute a perspective projection matrix.

Parameters:

  • fov (float) – The field of view in degrees.

  • aspect_ratio (float) – The aspect ratio of the viewport.

  • near (float, optional) – The distance to the near clipping plane. Defaults to 1e-6.

  • far (float, optional) – The distance to the far clipping plane. Defaults to 1e7.

Returns:

A 4x4 perspective projection matrix.

Return type:

torch.Tensor
