How to use Hidden Line Rendering to create an image that looks like a line drawing.

Hidden line rendering produces outline renderings of objects that are filled with flat, unshaded color. Silhouettes of surfaces include the effect of any bump or displacement maps.

Set the appearance of objects in the Hidden Line Rendering Parameters in the Render > Globals window and in each shader’s Control Window. If Hidden Line Parms in the Render Globals window is PER OBJECT, then the hidden line renderer uses the Hidden Line Rendering Parameters in each object’s shader (see Hidden Line Rendering Parameters in Render > Multi-lister). If Hidden Line Parms is GLOBAL, then the hidden line renderer uses the Hidden Line Rendering Parameters in the Render Globals window for all surfaces.

Hidden line rendering does not represent colors, textures, transparency, reflections, or shadows. The exact Anti-aliasing Levels Minimum and Maximum values (in the Render > Globals window) are not relevant during hidden line rendering. Any value above 0 turns on hidden line anti-aliasing. You should set the Post Filter parameter ON (in the Blur section of the Render > Globals window) when using hidden line rendering (see “Post Filter” in Blur Effects in Render > Globals).
