用Mathematica画出一个椅子的模型

以下是使用Mathematica绘制椅子模型的代码：

chair = Graphics3D[
  {
   (* 座位部分 *)
   Cuboid[{0, 0, 0}, {1.5, 0.25, 1}],
   Cuboid[{0.25, 0.25, 0.25}, {1.25, 0.5, 0.75}],
   Cuboid[{0.5, 0.5, 0.5}, {1, 0.75, 0.9}],
   Cuboid[{0.5, 0.5, 0.1}, {1, 0.75, 0.25}],
   Cuboid[{0.5, 0.5, 0.1}, {1, 0.6, 0.15}],
   Cuboid[{0.5, 0.5, 0.4}, {1, 0.6, 0.35}],
   Cuboid[{0.5, 0.5, 0.6}, {1, 0.6, 0.75}],
   Cuboid[{0.5, 0.5, 0.6}, {0.7, 0.25, 0.75}],
   Cuboid[{0.5, 0.25, 0.5}, {0.7, 0.4, 0.75}],

   (* 背部支架 *)
   Cylinder[{{1.25, 0.6, 0.75}, {1.25, 1.8, 0.75}}, 0.15],
   Cylinder[{{1.25, 1.8, 0.75}, {0.8, 2.2, 0.75}}, 0.15],
   Cylinder[{{1.25, 1.8, 0.75}, {1.5, 1.8, 1.2}}, 0.15],

   (* 背部部分 *)
   Cuboid[{0.8, 2.2, 0.6}, {1.5, 2.4, 1.2}],
   Cuboid[{0.8, 2.2, 0.75}, {1.5, 2.4, 0.9}],
   Cuboid[{0.8, 2.4, 0.6}, {1.5, 2.5, 1.2}],
   Cuboid[{0.8, 2.4, 0.6}, {1.5, 2.7, 0.75}],

   (* 扶手部分 *)
   Cuboid[{0, 0.25, 0}, {0.25, 2.2, 1}],
   Cuboid[{0.25, 0.25, 0.2}, {0.5, 1, 0.8}],
   Cuboid[{0.25, 0.25, 0.2}, {0.5, 0.75, 0.6}],
   Cuboid[{0.25, 0.75, 0.3}, {0.5, 1, 0.5}],
   Cuboid[{0.25, 1.2, 0.65}, {0.5, 1.6, 0.75}],
   Cuboid[{0.25, 1.6, 0.5}, {0.5, 2, 0.75}],
   Cuboid[{0.25, 2, 0.25}, {0.5, 2.2, 0.5}]
   }
  ]
  
Show[chair, ViewPoint -> {1.3, -2.4, 2}]

运行代码后，将会绘制出一个3D模型的椅子。
