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 |
