Indeed, it is possible to convert radial lines into parallel lines into one another. The original longitudinal parallel lines~ changed from plane to polar coordinates, and became the radiation lines we need. And both pictures b and c can be transformed back to the original picture a through back calculation.
Find specific methods:
It is known that b can be changed back to picture a through [polar coordinates to plane coordinates]; then we treat the picture x that needs to be processed as b; similarly to changing b back to a, change x into x1; and then add some vertical lines. Then use [plane coordinates to polar coordinates] to change this x1 back to x2 (similar to a to b). It can be seen that x2 is the effect of adding rays to x.
Here, for the shape on x, we used a dynamic brush (set size jitter, spread, spacing, etc.) to draw a ring of random points. In the third picture, we used the [Filter-Stylize-Wind] filter to simulate the trailing effect of the flames (why did we have a black background and a white picture in the first place? Because [wind] blows bright colors).
Some friends may be wondering how the vertical [wind] blows. Of course, first rotate the canvas 90 degrees ~ and then rotate it back after blowing. (It’s best to test the difference between blowing to the left and right.):
In addition, the [wind] effect will definitely not be good once, and the "tail" is not long enough. So we usually blow 3 or 4 times.
And we found that if we add a vertical line above the white line of x1, it will appear in the circle of x2 (the fireworks trail we want). If we add a vertical line below the white line of ) OK, let’s do a practical test:

Next we continue
The trail blown by the wind does not have the feeling of tiny sparks, but the feeling of light (continuous)~~ What should I do? We use the [Add Noise] filter to solve it. (You can master the degree yourself)
The basic methods have been explained. Please experience the specific steps yourself. :D If you can't do it, take a closer look, think more, and try it out! ! !
I don't want to teach you how to do a specific picture, but I want to explain a method. (If you don’t understand basic things, please search and refer to relevant information)
A few more mentions:
If you want to make text fireworks, you can type first, then [Convert text to path], and then use the set brush to [Stroke path]. The subsequent process is the same.
A completed firework was merged onto a black background layer. Then copy this layer to the image you need. Set the blending mode of this layer to [Screen] and that's it. This allows multiple fireworks to be superimposed.
After the fireworks are finished, you can use tools such as [Free Transform] to process them into different shapes. In addition, the polar coordinates can also be used in reverse, which can produce a parabolic tail.
Fireworks coloring: The lower layer (trailing layer) can be colored with Ctrl+U, or gradient mapping; the upper layer (light point layer) can be colored with layer style or Ctrl+U.
