Function sobol_burley::sample_4d [−][src]
pub fn sample_4d(sample_index: u32, dimension_set: u32, seed: u32) -> [f32; 4]
Expand description
Compute four dimensions of a single sample in the Sobol sequence.
This is identical to sample(), but computes four dimensions at once.
On x86-64 architectures it utilizes SIMD for a roughly 4x speed-up.
On other architectures it still computes correct results, but doesn’t
utilize SIMD.
dimension_set specifies which four dimensions to compute. 0 yields the
first four dimensions, 1 the second four dimensions, and so on.
Panics
- Panics if
dimension_setis greater than or equal toNUM_DIMENSION_SETS_4D. - In debug, panics if
sample_indexis greater than or equal to 2^16. In release, returns unspecified floats in the interval [0, 1).
