Geometry Node.

The Geometry node gives geometric information about the current shading point. All vector coordinates are in World Space. For volume shaders, only the position and incoming vector are available.

Inputs

This node has no inputs.

Properties

This node has no properties.

Outputs

Position
Position of the shading point.
Normal
Shading normal at the surface (includes smooth normals and bump mapping).
Tangent
Tangent at the surface.
True Normal
Geometry or flat normal of the surface.
Incoming
Vector pointing towards the point the shading point is being viewed from.
Parametric
Parametric coordinates of the shading point on the surface. To area lamps it outputs its UV coordinates in planar mapping and in spherical coordinates to point lights.
Backfacing
1.0 if the face is being viewed from the back side, 0.0 for the front side.
Pointiness
An approximation of the curvature of the mesh per-vertex. Lighter values indicate convex angles, darker values indicate concave angles. It allows you to do effects like dirt maps and wear-off effects.
