The Volume Rasterize Lattice operation takes lattice points and fills a volume
with data from the lattice geometry. Lattice points are a set of points with
several attributes defined. The
iz integer point attributes
identify the coordinates of each point in the lattice. The
attribute identifies each lattice point’s undeformed position.
The lattice points should be generated with Lattice from Volume.
The resulting volumes will be VDBs.
Which volumes are going to be modified by the lattice.
Deactivates values in the target volume prior to filling the volume with data from the lattice geometry.
Deactivates all values in the volume.
Deactivates values in the volume covered by the lattice in its rest position.
Specified what values should be written into the destination voxels covered by lattice voxel.
Set destination voxels to the point attribute interpolated from the lattice geometry. If multiple attributes are matched by the pattern, the destination volume’s name is used to select the attribute to interpolate.
Set destination voxels to the value sampled from the Source Volume geometry. If multiple volumes are matched by the pattern, the destination volume’s name is used to select the volume to sample.
Specifies the name of attribute on the lattice geometry to rasterize into the destination volume.
Enables smooth deformation.
Specifies the volumes from the third input to sample when writing values to the destination volume.
See specifying volumes.
Scale Density where Compressed
If a fog volume is modified, change its density based on expansion or compression of the corresponding lattice voxel.
Enable Max Density Scale
Detect and clamp the density change due to compression of the corresponding lattice voxel.
Max Density Scale
Specifies the maximum amount the density will be scaled due to compression of the corresponding lattice voxel.
Detect and collapse constant regions.
After building the VDB grid there may be undetected constant tiles. This tolerance is used to detect constant regions and collapse them. Such areas that are within the background value will also be marked inactive.
