    • Constructor Detail

      • Disk

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

    • Method Detail

      • 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​(java.nio.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
