Computes face normals for meshes.
tfg.geometry.representation.mesh.normals.face_normals( faces, clockwise=True, normalize=True, name=None )
This function supports planar convex polygon faces. Note that for non-triangular faces, this function uses the first 3 vertices of each face to calculate the face normal.
In the following, A1 to An are optional batch dimensions.
faces: A tensor of shape
[A1, ..., An, M, 3], which stores vertices positions of each face, where M is the number of vertices of each face. The rank of this tensor should be at least 2.
clockwise: Winding order to determine front-facing faces. The order of vertices should be either clockwise or counterclockwise.
booldefining whether output normals are normalized.
name: A name for this op. Defaults to "normals_face_normals".
A tensor of shape
[A1, ..., An, 3] containing the face normals.
ValueError: If the shape of
facesis not supported.
