Evaluates the Legendre polynomial of degree l and order m at x.
tfg.math.spherical_harmonics.evaluate_legendre_polynomial(
degree_l: TensorLike, order_m: TensorLike, x: TensorLike
) -> TensorLike
Note |
This function is implementing the algorithm described in p. 10 of Spherical
Harmonic Lighting: The Gritty Details .
|
Note |
In the following, A1 to An are optional batch dimensions.
|
Args |
degree_l
|
An integer tensor of shape [A1, ..., An] corresponding to the
degree of the associated Legendre polynomial. Note that degree_l must be
non-negative.
|
order_m
|
An integer tensor of shape [A1, ..., An] corresponding to the
order of the associated Legendre polynomial. Note that order_m must
satisfy 0 <= order_m <= l .
|
x
|
A tensor of shape [A1, ..., An] with values in [-1,1].
|
Returns |
A tensor of shape [A1, ..., An] containing the evaluation of the legendre
polynomial.
