This node reads Bifrost point clouds and volumes from an OpenVDB file.

Inputs

filename [in]

The file name. Use # to include the input frame number. The number of occurences of # determines the amount of padding. For example, file####.vdb resolves to file0001.vdb, file0002.vdb, and so on.

directory [in]

The directory.

frame [in]

The frame number. You can connect the frame output of a time node to a to_long node, and then connect the result here.

properties [in]

A space-delimited list of properties to read. Use * (asterisk) to specify all properties.

volume_subdivision_structure [in]

The volume subdivision structure of the output Bifrost volume.

adaptivity [in]

When Optimized is selected, will coarsen the read OpenVDB grids to reduce the number of voxels. Note, currently this only does something for level sets. When Off is selected, will read the OpenVDB grids with at least as fine resolution as what is in the file. Currently, VariedFromProperty does the same thing as Off.

rename_properties [in]

Rename properties to conform to Bifrost naming standards. Note, this only applies to non-Bifrost OpenVDB volumes.

Outputs

points [out]

The output Bifrost point clouds.

volumes [out]

The output Bifrost volumes.
