骨骼立方体——菱形十二面体折纸动画
几何画板及绘图内容加载中,请稍等……
① 该范例演示了一个由纸张折叠而成的“骨骼立方体”模型,其展开形态为菱形十二面体,并通过动画展示其折叠与展开的动态过程。② 核心数学概念涉及立体几何中的多面体(菱形十二面体)、空间变换(旋转与平移)以及参数化动画控制,同时隐含了对称性与拓扑结构。③ 作图要点:从构造摘要可见,使用了Point、Line、PolyLine、Segment、OrthogonalLine、Intersect、If、Plane、Polygon、Rotate、IntersectPath、RoofPoly2等GeoGebra命令,并创建了shift、K_1、T、S、m、g_1、D_2、h_1、Z_1、D_4、E_2、B_2、C_2、A_2、t、clock、rot1s、D、C、cc、A、C_1、B_1、A_1、Z、W、V、p、constClock、U、n、A1、rot1a、constSingle、rot0、bControl、rot1、J_1、I_1、G_1等对象,通过滑块(如rot1、rot0)和时钟(clock)控制旋转动画。④ 适合中学高年级至大学低年级的立体几何教学,也可用于折纸数学或动态几何演示,帮助学生直观理解多面体的空间结构与变换。
