FLASH中三维几何图形的处理

The Treatment of 3D Geometrical Image in FLASH

在中学数学教学中,让学生理解和掌握三维几何的结构是相当重要的。用FLASH动态地表示3D图形,能使学生更加直观了解和掌握几体结构。该文通过从数学角度出发,讨论了FLASH生成三维图形的原理,并完成立方体、八面体和球体的形成和动态变换。

It is important understanding various geometrical structures for students in middle school. Using FLASH technology, the 3D geometrical structures can be expressed dynamically, which enables students to understand the features of geometrical structures intuitively. In this paper, from the mathematical point of view, we have discussed the forming principle of 3D geometrical Image, completed the forming of cube, octahedral, and sphere image and achieved dynamical transform of 3D geometry.
