* \brief Generate a point set with blue noise properties
|
|
*
|
|
* Based on the paper "Parallel Poisson Disk Sampling with
|
|
* Spectrum Analysis on Surfaces" by John Bowers, Rui Wang,
|
|
* Li-Yi Wei and David Maletz.
|
|
*
|
|
* \param scene
|
|
* A pointer to the underlying scene
|
|
* \param shapes
|
|
* A list of input shapes on which samples should be placed
|
|
* \param radius
|
|
* The Poisson radius of the point set to be generated
|
|
* \param target
|
|
* A position sample vector (which will be populated with the result)
|
|
* \param sa
|
|
* Will be used to return the combined surface area of the shapes
|
|
* \param aabb
|
|
* Will be used to store an an axis-aligned box containing all samples
|
|
* \param data
|
|
* Custom pointer that will be sent along with progress messages
|
|
* (usually contains a pointer to the \ref RenderJob instance)
