| Description | Sets the current normal vector. Used for drawing three dimensional shapes and surfaces, normal() specifies a vector perpendicular to a shape's surface which, in turn, determines how lighting affects it. Processing attempts to automatically assign normals to shapes, but since that's imperfect, this is a better option when you want more control. This function is identical to glNormal3f() in OpenGL. | ||||||
