不规则形体是指其外形的凹凸变化没法用数学公式描述的形体，由于没有适当的数学模型，大多数编程语言和三维图形软件都没有提供不规则形体的直接生成功能。
Irregular Solid is the solid which form ' concavity and protruding change can 't be described by math formula , For lacking property maths model to the Irregular solid , majority programme and 3-D graphics software don 't offer the function of Irregular Solid directly generating .
