Class Summary
class RiSamplingStrategy
{
}; // RiSamplingStrategy
DESCRIPTION
Used to fill the data of an RiSamplePattern based on some sampling strategy
such as uniform or jittered. This class should be able to handle any number
of requested samples. This may mean that the sample pattern isn't perfect, for
example if the strategy is jittered 2D and the caller asks for 10 samples, the first
9 might be jittered on a 3x3 grid and the last sample chosen uniformly.
IMPLEMENTATION DETAIL
This class must be stateless to the extent that it can be shared among multiple
users with different sample pattern size needs.
PATTERN
Strategy
int CreateSamples(RiReal *samples, int numSamples, int numDimensions, RiRandom &gen) const;
- in numSamples
- Number of samples desired
- in numDimensions
- The dimension of the sample spaces
- in gen
- The random number generator to be used
- out realNum
- Number actually created (<= numSamples)
virtual int CreateSamples(RiReal *samples, int numSamples, int numDimensions, RiRandom &gen) const;
