How to draw a three-dimensional coordinate system using geometric sketchpad

Add custom tools. With the efforts of the majority of users, many basic graphics tools have been developed that can be used directly without drawing in the sketchpad. These tools can be loaded under the geometric sketchpad custom tool and can be called when making courseware.

Hold down the [Custom Tools] button in the left toolbox, and select [3D Basic Tools] in the pop-up shortcut menu. In the next menu, there is [Establish a three-dimensional coordinate system]. Select this menu here. as the picture shows.

After selecting the tool, click on the blank area of ​​the drawing board to draw a three-dimensional coordinate system. The three-dimensional coordinate system tool also includes [Three Views], [Horizontal and Vertical] Operation buttons such as Rotate] and [Hide Coordinate System and Grid] can demonstrate the three views of the coordinate system, and rotate the coordinate system to facilitate viewing of three-dimensional graphics drawn in this coordinate system.

If you want to do other things, such as drawing points, you can use [Orthogonal View Fixed Point] in [3D Basic Tools], which includes the three-dimensional coordinate system. Basic drawing, you can try it slowly by yourself.

The above is the detailed content of How to draw a three-dimensional coordinate system using geometric sketchpad. For more information, please follow other related articles on the PHP Chinese website!
