Normal Selection Node

The Normal Selection node creates a selection of elements whose normals point in a specified direction within a given angular threshold. It is useful for selecting geometry that faces a certain way, such as upward-facing surfaces, walls, or elements oriented toward a light or camera.

Inputs – Уводи

Напрям – Direction

A vector that defines the reference direction to compare against the element normals. The direction should typically be normalized.

Поріг – Threshold

The maximum angular difference between the element normal and the given direction for the element to be included in the selection.

Outputs – Виводи

Виділення

A boolean field indicating which elements have normals pointing within the given angular threshold of the specified direction.
