1 Basic Ideas

In this job, we need to implement a crane Simulation Software Based on OpenGL. Through analysis, we need to divide a large task into a small part. Therefore, the crane should be divided into several modules, and finally these modules can be assembled together. It can be divided into three parts: Head, body, and arms)

1.1 Front

The front can be divided into six sides: front and back, left and right, and top and bottom.

You can use a rectangle to draw the image above and below.

Draw the glass, lamp, and other parts. The glass is implemented using the bezr surface, and the lamp can be implemented using a disc.

The left and right sides can be drawn using multiple rectangles. (Glass needs to be drawn)

1.2 Body

The body consists of a site, 2 axles, and 4 wheels.

The website is drawn with a cube.

Two axles are implemented using two cylinders.

Four wheels can be achieved by adding a ring and a disc. To achieve this, you only need to implement one, and others can be achieved by rotating and translating.

1.3 Boom

The lifting arm includes two brackets, a long arm, and a rope on the long arm. There is a hook on the rope and an object on the hook.

Two brackets can be achieved through two cubes.

You can also use one cube to implement a long arm. But pay attention to the rotation, increase and decrease issues.

The rope, Hook, and object can be implemented as a whole, and finally translated to the end of the long arm.

A rope can be used as a very fine cylindrical string. The increase or decrease of the rope can be achieved by zooming the cylinder.

3 Operation

• X: rotate around the X axis; X: reverse rotate around the X axis

• Y: rotate around the X axis; Y: reverse rotate around the X axis

• Z: rotate around the X axis; Z: reverse rotate around the X axis

• S: Overall amplification; s: overall reduction

• Lifting key: Lifting Arm rising

• Down key: Boom descent

• 1: Rope rising

• 2: dropped rope

• 3: Lifting Arm Rotation

• 4: Reverse Rotation of the boom

• Left button: Move the car forward

• Right-click: The car returns

• F: Enter full screen

• F: exit full screen

• ESC key: exit the program

4 Running Environment
