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.

- 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 lights 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 Cycles Only
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.
- Random per Island Cycles Only
A random value for each connected component (island) of the mesh. It is useful to add variations to meshes composed of separated units like tree leaves, wood planks, or curves of multiple splines.
Get a random value for each instance of the mesh when using an Array modifier.
