I present you a new moving particle generator, one of those simple tools that can help you at any given moment to animate a festive or children's image with great success. It is simply called ParticleDevelop and its creators, the Japanese ICS define it as a HTML vector design tool, in English since it is only presented in this language and in Japanese, but don't let that pull you back because despite the language it is very simple to use and quite effective.
The first thing that surprises is that no download required as it can be edited online, and later download in an SGV file, or also in a png, jpeg or WebP image (only in Chrome), to take it later to the Illustrator or Photoshop, since it allows transparency embedding.
It comes with a viewer that shows the animated particles with a small square in the center, which is the point of origin where the particles are born. This box can be moved with the pointer to place said origin in the part of the viewer that we want. On this viewer we can work by making variations and seeing the results that they are displayed in real time.
In the right column It presents some 12 examples or templates that are later editable in different variables or settings. Entering the settings menu at the top, we have seen that it is possible to vary the shapes of the particles in some ways (there is not much to choose from: hearts, stars, ...), it is also possible to choose the colors, the force of gravity to make them fall or flow with less weight, the orientation of the flow direction of the particles by changing the angle. On the other hand, the source of particles can change in intensity, quantity, frequency, speed ...
The particle size is also editable, in origin and in end, achieving different effects of distancing the particles, or mass, causing them to dissolve as they evolve.
And two characteristics that I think are the best, one of them is that the alpha can be varied in the chrominance section, in saturation and in luminosity, so it is a matter of testing to achieve a good embedding. These settings can be saved by generating the html code and, as I said before, they can also be exported to a file.
The other virtue of this invention is that box width and height can be set to have an image window of the size that interests us.
The first utility that I see for this particle generator is to accompany images with backgrounds of dark and not very intense colors, since the particles themselves will animate a lot and give a lot of life. In fact, the creators place it on a black background as if they were fireworks (which are not seen during the day), so support them on darkened backgrounds. And above all never place them on letters or details that will be "eclipsed". A tip, do not abuse, the good is if brief ...
