How to use Grid Dilate & Erode node in Oraphim

Type ID: geometry.grid_dilate_erode
Category: Transform

What this node does

Processes grid, volume, or SDF data with the Grid Dilate & Erode operation.

The current Oraphim runtime registers 5 sockets and 4 properties for this node. Its main registered inputs are Grid, Connectivity, Tiles; its main outputs are Grid. The tables below are generated from the runtime registry rather than a handwritten approximation.

Inputs

Socket	Key	Type
Grid	grid	Geometry3D
Connectivity	connectivity	String
Tiles	tiles	String
Steps	steps	Int

Outputs

Socket	Key	Type
Grid	out_geometry	Geometry3D

Controls

Control	Key	Type	Group	Registry default
Data Type	dataType	String	Node	0.0
Connectivity	connectivity	String	Inputs	0.0
Tiles	tiles	String	Inputs	0.0
Steps	steps	Int	Inputs	1.0

How to use it

1. Add Grid Dilate & Erode from node search. Use geometry.grid_dilate_erode when you need the exact registry entry.
2. Connect a compatible Geometry3D source to Grid. Add the other inputs only when the operation needs them.
3. Start with the registry defaults and adjust Data Type, Connectivity, Tiles first so you can see the node's effect in isolation.
4. Route Grid (Geometry3D) into a compatible downstream node, viewer, or output path.
5. Preview a representative frame, change one input/control at a time, and save/reopen reusable graphs to verify persistence.

Practical example

Create a small test graph with Grid Dilate & Erode. Feed a compatible source into Grid. Change Data Type away from its registry default and compare the result. Connect Grid to a compatible downstream stage so the result is visible. Keeping this test graph small makes socket-type, context, and parameter mistakes easier to diagnose before the node is used in a production graph.

Troubleshooting

• If a connection is rejected, compare the exact socket data types in the tables above; Oraphim graph connections are typed.
• If the result looks unchanged, confirm this node is on the active path to the viewer/output and that the expected graph/resource is selected.
• If a control is unavailable, check required inputs and whether the property belongs to an internal or mode-dependent group.
• If a saved graph behaves differently later, reopen it and verify node identity, connections, and edited property values before rendering.
