Introduction

We introduce the basic technique for drawing non-photo realistic images of volume models. The turtle graphics approach to imitate painting operations is implemented in 3D space. Objects are defined by sets of scattered range data. Proposed technique demonstrate its applicability to non-photo realistic painting or hatching.

Examples

Meanders :
On the first figure you can see an imitation of meanders painted on a тАЬpureтАЭ sphere, on the second figure you can see a hatching on "head" shape with Gosper curve.

An example of hatching with fractal like objects.

Illustration of "hand drawing" on the 3D "seashell", where we first drew 5,000 fractal-like curves on the seashell at quasi-randomly generated screen positions, and Kanji with meaning of cherry blossoms was drawn by hand.
