Houdini 21.0 Nodes Geometry nodes

ML Volume Tile Component geometry node

Crops volumes so they can be used with other ML SOPs as training examples

On this page
Since 21.0

Overview

Volume Tile Component allows you to crop tiles from a given volume at one or multiple provided point positions. Those tiles are output as packed primitives. The outputs tie in with the example based ML SOPs workflow and can be input directly into the ML Example SOP. Make sure to enable “Use Packed Input/Target component”.

The node takes two inputs – the first is the VDB or native Houdini volume to crop tiles from, and the second takes the points where the tiles should be cropped at. If no points are provided it will crop a single tile from the center of the input volume.

Parameters

Volume

The volume primitives to crop tiles from.

Tile Settings

Tile Size

The size of the tile the node will crop at each point position.

Padding

The amount of voxel padding to be added on each side of the tile.

Safety Padding

The amount of safety padding to be added on each side of the tile internally. This allows for custom processing in the dive target that requires more information outside the tile borders to not cause any seams.

Hide Examples

Hides the volume primitive tiles to limit VRAM usage.

Inputs

Input Volume

A volume from which tiles should be cropped from.

Tile Points

One or more points, which mark the location of the tiles.

Outputs

Output Components

One or more packed primitives (components) that hold one tile, consisting of one or multiple fields, each.
