In order to classify unknown 3d objects into a set of pre-determined object classes, the paper proposes a 3d object classification approach based on improved interpretation tree.

为了实现对未知三维物体的分类，提出了一种基于改进解释树的三维物体分类方法，将未知物体分到一组预先定义的物体类中。

SquirrelFish differs from the previous implementation of the interpreter in that it uses a bytecode based strategy rather than syntax tree-walking interpretation.

与之前的解释器使用遍历语法树的实现方式不同的是，SquirrelFish的实现采用字节码。
