Abstract: A method for modeling geometry of apple fruit is proposed . It uses Bézier curves to fit the fruit outline, and control prism of the fruit surface by introducing a noise function which conforms to the variety characteristic. The model uses a few of parameters with significant biology meaning and is easy to integrate with agricultural knowledge. It proposes face color random filling method based color table to solve the characteristic of numerous types of apple fruit and rich colors of apple face except uses texture mapping to render apple face. The results show this method can simulate various types of apple fruit and has better realistic effect.
