generate_sample_at()

SampleResult MayaFlux::Kinesis::generate_sample_at	(	SpatialDistribution	distribution,
		size_t	index,
		size_t	total,
		const SamplerBounds &	bounds,
		Kinesis::Stochastic::Stochastic &	rng
	)

Generate a single sample at a specific index (for indexed/sequential modes).

Parameters

distribution	Spatial distribution algorithm
index	Sample index within the total sequence
total	Total number of samples in the sequence
bounds	Spatial domain
rng	Stochastic engine

Returns

Single SampleResult

Useful for ParticleNetwork's per-index generation pattern.
