# New/Updated Input and Info Nodes

<!-- * ### Vertex Neighbor Count `Neighbor Count`
* Dropdown select
* Number of Adjacent Points
* Number of Adacent Edges
* Number of Adjacent Faces
-->

## Global Input Nodes

* ### Index: - @HansGoudey
* ***Committed [D13358](https://developer.blender.org/D13358)***
* Add "Domain Size" field output.
* Add "Factor" field output that is between 0 and 1.

* ### Scene Time: - @guitargeek
* ***Comitted [D13455](https://developer.blender.org/D13455)***
* Add "Seconds" field output.
* Add "Frames" field output.

* ### Attribute Domain Size - @guitargeek
* ***Comitted [D13365](https://developer.blender.org/D13365)***
* Outputs a single value, not a field.
* Point, Edge, Face, Face Corner, Spline, Instance
* In attribute category
* Benefits:
* No need to have a separate node for all geometry types
* Teaches about attribute domains
* The name is much less generic than the alternative nodes
* Instead of "Mesh Info", "Curve Info", "Point cloud Info"

* ### Neighbor Count `Mesh Topology?` [D13343 WIP](https://developer.blender.org/D13343)
* Domain Dropdown: `Vertex`, `Edge`, `Face`, `Face Corner?`
* Vertex
* `Adjacent Vertex Count` *This is the same as an edge count, since every edge leads to a vertex*
* `Adjacent Face Count`
* Edge
* `Connected Face Count`
* `Boundary Edges` *Or a separate node? Depends on node name*
* Face
* `Face Vertex Count` *Mpoly.totloop*
* Face Corner
* ?

* ### Edge Length [D13343 WIP](https://developer.blender.org/D13343)
* `Edge Length`

* ### Edge Direction [D13343 WIP](https://developer.blender.org/D13343)
* `Edge Direction` (Two possible directions, choice is made by pointing in the direction of the larger index) -->

<!-- * ### Edge Neighbor Count
* Dropdown select
* Number of Adjacent Edges
* Number of Adjacent Faces -->

<!-- * ### Face Edge Count [D13343 WIP](https://developer.blender.org/D13343) -->

## Curve Input Nodes
* ### Curvature - [D12550](https://developer.blender.org/D12550)
* Angle
* The angle between consecutive control points, in radians (0 for straight)
* Pro: Simple
* Con: Changes when the curve becomes more dense
* Radius
* The radius of an arc described by a control point and its neighbors
* Pro: Does not depend on density of curve
* Con: Depends on the size of the curve
* ==Ready for Review==
* ### Spline Length - @guitargeek
* ***Committed [D13279](https://developer.blender.org/D13279)***
* Spline Point Count

* ### Spline Parameter (Renamed from Curve Parameter) - @guitargeek
* ***Committed [D13275](https://developer.blender.org/D13275)***
* Add Index

<!-- * Segment Length [D13279](https://developer.blender.org/D13279)-->

* ### Segment Length [D13373](https://developer.blender.org/D13373) - @guitargeek
* `Segment Length`
* Refers to the length of the following segment (the segment of the same index as the point)
* On non-cyclic splines, the last point value is zero
