Abstract

This article analyzed the drawing styles of Japanese animes, and then presented a Shader-based NPR 3D real-time rendering algorithm that implements these styles. The 3D scenes rendered by this method have the following features: outlining the edges with constant thickness lines, shading the objects with sharp colors and anime-style shadows. This algorithm takes advantages of GPU shaders, and is applicable to real-time rendering applications, such as games and demos.
