How to use Mesh to SDF Grid node in Oraphim

Type ID: geometry.mesh_to_sdf_grid
Category: Transform

What this node does

Converts incoming data with the Mesh to SDF Grid operation for use later in the graph.

The current Oraphim runtime registers 4 sockets and 2 properties for this node. Its main registered inputs are Mesh, Voxel Size, Band Width; its main outputs are SDF Grid. The tables below are generated from the runtime registry rather than a handwritten approximation.

Inputs

Socket	Key	Type
Mesh	mesh	Geometry3D
Voxel Size	voxelSize	Float
Band Width	bandWidth	Int

Outputs

Socket	Key	Type
SDF Grid	out_geometry	Geometry3D

Controls

Control	Key	Type	Group	Registry default
Voxel Size	voxelSize	Float	Inputs	0.30000001192092896
Band Width	bandWidth	Int	Inputs	3.0

How to use it

1. Add Mesh to SDF Grid from node search. Use geometry.mesh_to_sdf_grid when you need the exact registry entry.
2. Connect a compatible Geometry3D source to Mesh. Add the other inputs only when the operation needs them.
3. Start with the registry defaults and adjust Voxel Size, Band Width first so you can see the node's effect in isolation.
4. Route SDF 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 Mesh to SDF Grid. Feed a compatible source into Mesh. Change Voxel Size away from its registry default and compare the result. Connect SDF 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.
