Py5Graphics.normal()

Sets the current normal vector.

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. Py5 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 gl_normal3f() in OpenGL.

This method is the same as normal() but linked to a Py5Graphics object. To see example code for how it can be used, see normal().

Underlying Processing method: PGraphics.normal
