Grease pencil: integrating animated freehand drawings into 3D production environments

Freehand drawing is one of the most flexible and efficient ways of expressing creative ideas. However, it can often also be tedious and technically challenging to animate complex dimensional environments or dynamic choreographies. We present a case study of how freehand drawing tools can be integrated into an end-to-end 3D content creation platform to reap the benefits from both worlds. Creative opportunities and challenges in achieving this type of integration are discussed. We also present examples from short films demonstrating the potential of how these techniques can be deployed in production environments.
