tfg.geometry.representation.triangle.normal

Computes face normals (triangles).

tfg.geometry.representation.triangle.normal(
    v0,
    v1,
    v2,
    clockwise=False,
    normalize=True,
    name=None
)

Defined in geometry/representation/triangle.py.

Note:

In the following, A1 to An are optional batch dimensions, which must be broadcast compatible.

Args:

  • v0: A tensor of shape [A1, ..., An, 3], where the last dimension represents the first vertex of a triangle.
  • v1: A tensor of shape [A1, ..., An, 3], where the last dimension represents the second vertex of a triangle.
  • v2: A tensor of shape [A1, ..., An, 3], where the last dimension represents the third vertex of a triangle.
  • clockwise: Winding order to determine front-facing triangles.
  • normalize: A bool indicating whether output normals should be normalized by the function.
  • name: A name for this op. Defaults to "triangle_normal".

Returns:

A tensor of shape [A1, ..., An, 3], where the last dimension represents a normalized vector.

Raises:

  • ValueError: If the shape of v0, v1, or v2 is not supported.
