Well a pretty advanced demo if you are just getting started with animation and GSAP but for good reasons. The demo you posted uses HTML elements to create those stars and without any other content or animation it is struggling to run at 30FPS, now imagine using other animations on top of it and freezing your user's browsers. So it makes a lot of sense to use Canvas for it.

 

I have left a lot of comments explaining almost every bit of the code that will explain all the math and tricks behind animation. You can reference docs for anything that you don't understand related to GSAP or google stuff related Canvas. But feel free to ask any questions.

 

See the Pen NyVrjY?editors=0010 by Sahil89 (@Sahil89) on CodePen

 

If you have done any canvas related animation there are many things worth noting in terms of performance. Like all paths are being drawn at once before they are painted on the canvas. It helps because all particles are of same color. If they were of different colors then it will take a lot more processing but I believe it will still easily animate 500 particles of different colors.

 

For better performance, use a plain div tag with background image or gradient instead of trying to paint it on canvas.

 

I know it is advanced demo and may not be what you expected though still give it a try and try to go through the code it. If you feel like you won't able to understand it, I have planned post a video tutorial in couple of days.

Hi Sahil,

Thank you for the insight relation between of canvas and GSAP.

As I said earlier I'm a beginner and have been trying on the features and putting them into practice.

However I'm still having problem to  understand all of it .

You have mentioned that you could explain it in a video which I think would be really helpful 

Thank you again for your effort :)
