The image of sinusoidal function is an important part of high school mathematics. But for many students, the content of this class is too abstract to be understood. Therefore, the mathematics teacher chooses to use the courseware to demonstr

We can often see some of the waves of ripples in the Internet animation ads, the effect is very lifelike. In fact, this is only a clever use of the animation software in the matte effect produced. In fireworks, you can also make this wave-rippling GIF animation by subtly adjusting the mask effect and the playback time of each frame.
Let's start with a picture that will be used to make this ripple effect into fireworks. Then fireworks automatically gen
The results of the tutorial are divided into two parts. The first is the use of filters to create a pattern of water waves (PS has its own water wave filter), because the filter effect is random, the production of a pattern will have some differences. Then is the overall color palette and local color palette. Tones can be adjusted according to your preferences.
