irtk.sampling.sample_hemisphere

irtk.sampling.sample_hemisphere(batch: int, radius: float, method: Literal['uniform', 'fibonacci'] = 'uniform', axis: int = 1) → torch.Tensor

Sample points on a hemisphere.

Parameters:

• batch – Number of points to sample.

• radius – Radius of the hemisphere.

• method – Sampling method, either ‘uniform’ or ‘fibonacci’.

• axis – Axis to use as up direction (0 for x, 1 for y, 2 for z).

Returns:

Sampled points on the hemisphere with shape (batch, 3).

Return type:

torch.Tensor
