本文旨在讨论计算中的某些数学问题，计算机艺术与通常艺术作品不同之点在于它特有的数学结构，因而数学模型与方法在理论与实践都起着重要作用，本文对诸如几何模型，数学变换，迭代算法，动画等某些实用技巧作为概述，还介绍了关于审美准则的数学描述。

This paper focuses on some mathematical problems in computer art. Computer art is different from general art works, for its digital structure so mathematical models and methods play important roles in both theoretical and practical research. This paper provides a general description of some practical techniques,such as geometric modeling, mathematical transformation,iterative scheme, animation and so on. Finally, the mathematical description about aesthetic criterion is also introduced.
