所属专题 Calculus Concepts
本范例演示通过截面从笛卡尔平面生成的立体图形。核心数学概念包括积分、体积计算和几何形状的构造。构造要点使用了GeoGebra命令如If、Midpoint、Polygon、CircumcircleArc、Segment、ImplicitCurve、Integral等，通过滑块和输入框可以调整截面形状（如正方形、等边三角形、半圆等）并观察其生成的立体图形。适合高中及以上学生用于理解立体几何和微积分中的体积积分概念。

AI 绘图提示语参考

绘制一个由不同截面形状从笛卡尔平面延伸生成的立体图形。截面形状包括正三角形、正方形、半圆、矩形和等腰三角形，通过输入框调整截面位置和高度。截面两端点由直线定义，中点用于确定截面中心。截面面积根据形状计算，体积通过积分求得。图形包含隐式曲线定义的x坐标范围，以及输入框用于设置截面参数。
