Category: Generator
What this node does
The Curve Primitive node is registered in Oraphim's Generator category and performs the graph operation represented by its sockets and controls below.
The current Oraphim runtime registers 3 sockets and 16 properties for this node. Its main registered inputs are no fixed inputs; its main outputs are Curve, Curve, Curve Type. The tables below are generated from the runtime registry rather than a handwritten approximation.

How to use it
- Add Curve Primitive from node search. Use
motion.geometry.curve_primitivewhen you need the exact registry entry. - Place the node as a source/context operation; it has no fixed input socket in the current registry.
- Start with the registry defaults and adjust Curve Type, Start X, Start Y first so you can see the node's effect in isolation.
- Route Curve (
Geometry3D) into a compatible downstream node, viewer, or output path. - 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 Curve Primitive. Change Curve Type away from its registry default and compare the result. Connect Curve 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.
