Silhouettes and Creases

The lines we detect and draw consist of two parts, silhouette and crease lines. The silhouette lines mainly captures the boundary pixels of objects, while crease lines captures interior lines of objects. We combine those two lines to generate final line drawing.

The line width, color, and detection threshold of each line can be controlled in the material instance of PP_CharCelShading_silhouette_and_crease material (Figure 2). If you don’t want to draw crease, you can input 0 in the crease line width.
