SplineEditor

# WORK IN PROGRESS Do not count on this as part of your workflow yet, probably contains lots of bugs and stability is not guaranteed!! ## Graphical editor to create values for various ## schedules and/or mask batches. **Shift + click** to add control point at end. **Ctrl + click** to add control point (subdivide) between two points. **Right click on a point** to delete it. Note that you can't delete from start/end. Right click on canvas for context menu: NEW!: - Add new spline - Creates a new spline on same canvas, currently these paths are only outputed as coordinates. - Add single point - Creates a single point that only returns it's current position coords - Delete spline - Deletes the currently selected spline, you can select a spline by clicking on it's path, or cycle through them with the 'Next spline' -option. These are purely visual options, doesn't affect the output: - Toggle handles visibility - Display sample points: display the points to be returned. **points_to_sample** value sets the number of samples returned from the **drawn spline itself**, this is independent from the actual control points, so the interpolation type matters. sampling_method: - time: samples along the time axis, used for schedules - path: samples along the path itself, useful for coordinates - controlpoints: samples only the control points themselves output types: - mask batch example compatible nodes: anything that takes masks - list of floats example compatible nodes: IPAdapter weights - pandas series example compatible nodes: anything that takes Fizz' nodes Batch Value Schedule - torch tensor example compatible nodes: unknown

Outputs

Index	Name	Type	Is List	Connection Reference
0	mask	MASK	No	["{node_id}", 0]
1	coord_str	STRING	No	["{node_id}", 1]
2	float	FLOAT	No	["{node_id}", 2]
3	count	INT	No	["{node_id}", 3]
4	normalized_str	STRING	No	["{node_id}", 4]

How to connect to these outputs

To connect another node's input to an output from this node, use the connection reference format:

["node_id", output_index]

Where node_id is the ID of this SplineEditor node in your workflow, and output_index is the index from the table above.

Example

If this node has ID "5" in your workflow:

• mask (MASK): ["5", 0]
• coord_str (STRING): ["5", 1]
• float (FLOAT): ["5", 2]
