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. HoldingCtrl
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.
