Map Point Cloud to Regular Grid

Group (Subgroup)

Sampling (Mapping)

Description

This Filter determines, for a user-defined grid, in which voxel each point in a Vertex Geometry lies. The user can either construct a sampling grid by specifying the dimensions, or select a pre-existing Image Geometry to use as the sampling grid. The voxel indices that each point lies in are stored on the vertices.

Additionally, the user may opt to use a mask; points for which the mask are false are ignored when computing voxel indices (instead, they are initialized to voxel 0).

Parameters

Name Type Description
Sampling Grid Type Enumeration The method used to create the sampling grid, either Manual or Use Existing Image Geometry
Grid Dimensions int 3x Dimensions of the sampling grid, if Manual is selected
Use Mask bool Whether to use a mask for the input Vertex Geometry

Required Geometry

Vertex

Required Objects

Kind Default Name Type Component Dimensions Description
Data Container None N/A N/A Data Container holding the input Vertex Geometry
Data Container None N/A N/A Data Container holding the sampling Image Geometry, if Use Existing Image Geometry is selected
Vertex Attribute Array None bool (1) Vertex mask, if Use Mask is selected

Created Objects

Kind Default Name Type Component Dimensions Description
Vertex Attribute Array VoxelIndices size_t (1) Indices of the voxels in which each point lies
