Contour Rendering

Approach 1: Mesh Displacement and Culling

Description

This is a mesh-based technique to rendering contours, where meshes are duplicated, flipped, and then displaced outside.

• Pros
  • Thickness can be controlled using textures.
  • Contours can be displaced in the viewport.
  • The same effect can be easily reproduced in other real-time rendering environment such as Unity.
  • ...
• Cons
  • Ridges, valleys, and suggestive contours are not supported.
  • ...

Usage

• Select target objects
• 3D Viewport > Object > BToon Utilities > Set Contours

Implementation

• It applies Solidify and Displace modifiers to the selected objects.
• An emission-based material with backface culling enabled is created and set to contours.

Future Work

• Utilities for composition-based contour rendering
• Utilities for FreeStyle-based contour rendering
