Nodo Esquinas de borde

El nodo Esquinas de borde.

Selects a neighboring face corner of an edge 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 an edge from the geometry based on the Edge Index.

  • Find some (not all) face corners connected to this edge – see below.

  • 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.

Advertencia

As illustrated below, the node only looks at one corner per connected face. Even though the edge has four neighboring corners, Corner Index can only return the indexes of two of them, and Total will similarly return 2.

You can use the Nodo Desplazar esquina en cara to retrieve the indexes of the other corners.

A graphic for which corners are returned for a given edge

  • Rojo: borde seleccionado.

  • Blue: the corners whose index can be retrieved using this node.

  • Purple: the corners that can be retrieved by offsetting the blue corner indices using the Nodo Desplazar esquina en cara.

Entradas

Identificador de borde

The index of the edge for which to find connected corners.

Nota

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 Edge domain.

Influencias

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.

Identificador de ordenamiento

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

Propiedades

Este nodo no contiene propiedades.

Salidas

Identificador de esquina

The geometry-wide index of the selected corner. You can pass this to the Nodo Evaluar en identificador or the Nodo Muestrear identificador (with the domain set to Face Corner) to retrieve details about the corner.

If the edge has no connected corners, Corner Index will be zero.

Total

The number of faces (not face corners!) connected to the edge.
