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.
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.
