Corners of Face Node¶

Selects a corner of a face and outputs its index.

This node is a bit special because it operates in two different domains. First, it evaluates a Weight for each corner in the geometry. Then, for each item in the context domain, it will:

Pick a face from the geometry based on the Face Index.
Find the corners of this face.
Sort these corners by their associated weight.
Pick a corner from the above sorted list based on the Sort Index, where 0 means the corner with the lowest weight, 1 means the corner with the second-lowest weight and so on.
Output the geometry-wide index of this corner.

Inputs¶

Face Index

The index of the face for which to find the corners.

Merknad

If this input is not connected, it uses the index of the context item, which means it’s important that the node is evaluated in the Face domain.

Weights

The weights of the corners in the geometry. Unlike the other inputs which follow the context domain, this one is always evaluated in the Face Corner domain.

The corners are sorted by their associated weight in ascending order. Corners with the same weight are sorted by their index.

Sort Index

The 0-based index of the corner to select from the face’s sorted corners. If this value is outside the range of valid indices, it wraps around.

Properties¶

This node has no properties.

Outputs¶

Corner Index: The geometry-wide index of the selected corner. You can pass this to the Evaluate at Index Node or the Sample Index Node (with the domain set to Face Corner) to retrieve details about the corner.
Total: The number of corners in the face, which is also its number of edges.
