Detailed method of controlling parameter changes through animation buttons in Geometric Sketchpad

php editor Youzi will introduce to you today a variety of parameter control techniques - the geometric sketchpad controls parameter changes through animation buttons, allowing the sketchpad to create richer effects and dynamics. The geometric sketchpad is a very interesting and creative painting tool that can produce various effects by using geometric shapes and parameters such as color and width. This technique allows users to control parameter changes more conveniently, making sketchboard creation more flexible. Change. This article will introduce in detail the implementation method of controlling parameter changes through animation buttons in Geometric Sketchpad.

1. Create parameters

Click the [Data] menu and select the [New Parameter (W)] command. The dialog box as shown below will appear. The parameters have no unit by default. After clicking OK, the parameters appear in the drawing area. (You can also create new parameters through [Calculate], [New Function] or right-click the drawing area).

2. Set parameter animation

Select the parameter (frame selection or click on the background of the parameter), select [Edit]-[Operation Button]-[Animation 】, open the animation properties dialog box of the parameter, and make relevant settings as needed. The [Direction] controls whether the parameter becomes larger or smaller. The unit change per second is the rate of parameter change. The range of change controls the extreme value of the parameter. After clicking [OK], an [Animation Parameters] button will appear in the workspace. Click this button and the parameters will change according to the settings. The parameter transformation range has exceeded the 4320 upper limit of version 5.0, and the specific upper limit has not been measured. The set [Range] is only the range of the parameter [Animation]. If you change the size of the parameter manually, it will not be limited by this range.

The above is the detailed content of Detailed method of controlling parameter changes through animation buttons in Geometric Sketchpad. For more information, please follow other related articles on the PHP Chinese website!
