Graphics3D
 Usage
• Graphics3D[primitives, options]表示一个三维图形.
Notes
• Graphics3D使用Show显示. • 可以使用下列图形指令:

• 可以给出图形指令的嵌套列表. 诸如GrayLevel的指定实际上只保持到直至包含它们的列表末尾. • Graphics[ ... ]的标准输入形式是-Graphics-.InputForm输出指令的显式列表. • 被使用的缺省光源是    1,0,1 , RGBColor[1,0,0] ,   1,1,1 , RGBColor[0,1,0] ,   0,1,1 , RGBColor[0,0,1]  . • Graphics3D[SurfaceGraphics[ ... ]] 可以被用来把一个 SurfaceGraphics 对象转化为 Graphics3D 表示. • Graphics[SurfaceGraphics[ ... ]]根据普通2D图形指令产生一个表示.
 Further Examples
Beside using functions like Plot3D, you create three-dimensional graphics with graphics primitives. The command draws a random quadrilateral. Evaluate the cell to see the graphic.
