Normal Node#

Normal Node.

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

Inputs#

Normal

Normal vector input.

특성#

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.
