Get Normal in Geometry
Overview
Provides the "Normal in Geometry" of the current Render State. The Render State is affected by any shaders which were called before this function is called, among other things.
The input connection is not used by this node (consistent with all Get nodes).
Normal in Geometry is the surface normal, in world space, of the original undisplaced point on the surface being rendered. When sampling an atmosphere shader, Normal in Geometry is usually set to the local "Up" vector with respect to the planet to which the atmosphere shader is attached.
Settings:
- Name: This setting allows you to apply a descriptive name to the node, which can be helpful when using multiple Get Normal in Geometry nodes in a project.
- Enable: When checked, the node is active, and when unchecked the node is ignored.
