ABSTRACT
MatCap is an expressive approach to shade 3D models and is promising for the production of typical Japanese-style cel-shaded animations. However, we experienced an asset management problem in our previous short film production; we needed to manually create many MatCap assets to achieve variations shot by shot or even frame by frame. In this work, we identify requirements for shading systems in Japanese animation production and describe our procedural MatCap system, which satisfies the requirements. Procedural MatCap generates customizable MatCap assets fully procedurally in run time, which drastically improves the asset manageability.

Shadows for cel animation
SIGGRAPH '00: Proceedings of the 27th annual conference on Computer graphics and interactive techniquesWe present a semi-automatic method for creating shadow mattes in cel animation. In conventional cel animation, shadows are drawn by hand, in order to provide visual cues about the spatial relationships and forms of characters in the scene. Our system ...
2D shading for cel animation
Expressive '18: Proceedings of the Joint Symposium on Computational Aesthetics and Sketch-Based Interfaces and Modeling and Non-Photorealistic Animation and RenderingWe present a semi-automatic method for creating shades and self-shadows in cel animation. Besides producing attractive images, shades and shadows provide important visual cues about depth, shapes, movement and lighting of the scene. In conventional cel ...
3D Character Model Creation from Cel Animation
CW '04: Proceedings of the 2004 International Conference on CyberworldsWhen creating a cel animation, the animators often use 3D character models to add some effects on the character or to generate intermediate images between the key frames. However, it is a troublesome and time-consuming task to create a 3D model. In this ...
