When I was young, everyone played a kaleidoscope. The kaleidoscope is a cylindrical toy. The inner wall of the tube is a triangular prism consisting of three glass mirrors. One end of the tube is filled with broken glass or paper scraps of various shapes and colors. When the eye is seen at the other end of the tube, due to the reflection of the multi-faceted mirror, various patterns can be seen, like blooming flowers. With the three-dimensional function of Zhongwang CAD, it is possible to build a model like a kaleidoscope, and perform CAD rendering after giving the material of the object, which can achieve the kaleidoscope viewing effect. The following describes how to use Zhongwang CAD to carry out the actual operation process.
First, starting from the mirror surface of the inner wall of the kaleidoscope, use the command of drawing the cuboid in the Zhongwang CAD to create a 50X10X1 cuboid for later use as a mirror.
Since the three mirrors are required to form a triangular prism, it is necessary to perform some cutting work on the side of the rectangular parallelepiped made above, so that the two sides of the rectangular parallelepiped become a 30 degree oblique angle. Specifically, two stretching entities that need to be cut off can be made. The blue solid part of the following figure uses the difference function of the Boolean operation to cut the blue solid part on the rectangular parallelepiped so that the adjacent two faces become 30 degrees. angle.
Use the Rotate and Copy commands to create three additional mirrors and move them to combine the three mirrors to form a triangular prism.
