Action type identifier.
OptionalminMinimum Gaussian contribution at a cluster voxel center to be kept. Default: 0.1
OptionalopacityOpacity threshold for solid voxels. Default: 0.999
OptionalseedSeed position for finding the connected component. Default: Vec3(0,0,0)
OptionalvoxelVoxel size in world units for coarse voxelization. Default: 1.0
Filter Gaussians to keep only those in the connected cluster at a seed position.
GPU-voxelizes the scene at a coarse resolution, finds the connected component of occupied blocks containing the seed, and keeps only Gaussians whose AABB overlaps that cluster.
