  • Constructor Details

    • Disk

      public Disk()
      Create a new instance of BestCandidateSampling.Disk to configure and generate 'best candidate' sample positions on the unit disk.

  • Method Details

    • seed

      public BestCandidateSampling.Disk seed(long seed)
      Set the seed to initialize the pseudo-random number generator with.
      Parameters:
      seed - the seed value
      Returns:
      this

    • numSamples

      public BestCandidateSampling.Disk numSamples(int numSamples)
      Set the number of samples to generate.
      Parameters:
      numSamples - the number of samples
      Returns:
      this

    • numCandidates

      public BestCandidateSampling.Disk numCandidates(int numCandidates)
      Set the number of candidates to try for each generated sample.
      Parameters:
      numCandidates - the number of candidates to try
      Returns:
      this

    • generate

      public BestCandidateSampling.Disk generate(float[] xys)
      Generate 'best candidate' sample positions and store the coordinates of all generated samples into the given xys float array.

      This method performs heap allocations, so should be used sparingly.

      Parameters:
      xys - will hold the x and y coordinates of all samples in the order XYXYXY.... This array must have a length of at least numSamples
      Returns:
      this

    • generate

      public BestCandidateSampling.Disk generate(FloatBuffer xys)
      Generate 'best candidate' sample positions and store the coordinates of all generated samples into the given xys FloatBuffer.

      The samples will be written starting at the current position of the FloatBuffer. The position of the FloatBuffer will not be modified.

      This method performs heap allocations, so should be used sparingly.

      Parameters:
      xys - will hold the x and y coordinates of all samples in the order XYXYXY.... This FloatBuffer must have at least numSamples remaining elements. The position of the buffer will not be modified by this method
      Returns:
      this

    • generate

      public BestCandidateSampling.Disk generate(Callback2d callback)
      Generate 'best candidate' sample positions and call the given callback for each generated sample.

      This method performs heap allocations, so should be used sparingly.

      Parameters:
      callback - will be called with the coordinates of each generated sample position
      Returns:
      this
