VoxelizedSourcePDFSampler

This is an alternative to GateSPSVoxelsPosDistribution (c++)

class opengate.source.VoxelizedSourcePDFSampler.VoxelizedSourcePDFSampler(itk_image, version=1)

This is an alternative to GateSPSVoxelsPosDistribution (c++) It is needed because the cond voxel source is used on python side.

There are two versions, version 2 is much slower (do not use)

init_cdf()

searchsorted2d(a, b)

sample_indices_slower(n, rs=np.random)

This version seems slower than the other version with np random choice

samples_g4(n)

sample_indices(n, rs=np.random)

sample_indices_phys(n, rs=np.random)
