The Faces Rendering option allows you to display just one, or both, sides of a material surface.
You can switch between rendering both sides of a material surface or just the front face.
Single-sided rendering (back-face culling) is often a good choice for 3D scans. Other applications include Cel Shading and Cartoon Outlines.
Back-Face Culling
A rendering process that hides or ignores the back polygons of a 3D object—the sides facing away from the camera—to optimize performance and render speed.
Cel Shading
A non-photorealistic rendering technique that uses flat colors and hard shadow steps instead of smooth gradients, giving 3D models a hand-drawn or comic book appearance.
Cartoon Outlines
An artistic rendering effect that draws prominent black or colored borders around the silhouette and outer edges of a 3D mesh to create a stylized, illustrated look
