# Normal Node¶

Normal Node.

The Normal node generates a normal vector and a dot product.

## Inputs¶

Normal
Normal vector input.

## Properties¶

Normal Direction
To manually set a fixed normal direction vector. LMB click and drag on the sphere to set the direction of the normal. Holding Ctrl while dragging snaps to 45 degree rotation increments.

## Outputs¶

Normal
Normal vector output.
Dot

Dot product output. The dot product is a scalar value.

• If two normals are pointing in the same direction the dot product is 1.
• If they are perpendicular the dot product is zero (0).
• If they are antiparallel (facing directly away from each other) the dot product is -1.
