Inputs:

• sizeI - [required] Size of volume from which points are to be sampled
• spacing - [required] Minimum sepration distance between points
• nPts - [Default is 0] if nPts = 0 For poisson disc sampling. nPts = k to sample k-pts from N-dimensional space with minimum separation distance
• showIter - [Default is 0] If showIter == 1, this option can be used to see how points are generated through each iteration. It can be useful when code is taking a long time to generate points.

Output:

• pts - All eligible points

Example:

• Poisson disc sampling in 2D space.

sizeI = [512,512];  
spacing = 30;  
pts = poissonDisc(sizeI,spacing);  

• Sample k-pts in 3D space.

sizeI = [512,512,192];  
spacing = 6;  
nPts = 10000;  
pts = poissonDisc(sizeI,spacing,nPts);  

• Show iteration progress from poisson disc sampling in 2D

sizeI = [512,512];  
spacing = 6;  
nPts = 0;  
showIter = 1;  
pts = poissonDisc(sizeI,spacing,nPts,showIter);  

poisson-disc-sampling's Issues

3D Error

Hello, I tried using your code in Matlab for 3D sampling but the error shown below was given.

Index in position 2 exceeds array bounds.

Error in poissonDisc (line 106)
D = D(:,2);

Please help

ask for some help

hello~
i'm a beginner about image processing. recent study the poisson sampling. i test your excellent code.
but i have a question about the input. if i have some 3d data, i want to use the code to sample the data.
how can i achieve the goal?

look forward to your reply~ thank you~
