This is my first three.js project.

You’re a man of few words, so your project went almost unnoticed, which would have been a shame!
I think it’s a cool idea, and very well presented as such! You even thought of dissolving the effect, although I’m not sure about the “bio” part of the “bio degradabilty” 
One word about your animation loop:
while I understand that the dissolving effect is a very subtle animation, there remains a very high residual GPU load of approx. 80% on my iMac, once the dissolution is complete and no user input has occurred. That part has some potential for improvement.
GrĂĽezi Christoph,
Thank you for your compliments and observations.
Yes, I also noticed that for some reason at the very end the GPU load becomes uncomfortable.
IDK if it’s because I’m increasing size and decreasing opacity in a very subtle step, while still rotating the sprite.
Yeah, the bio part is question of some research and experiment. Thank goodness my wife is a biochemist
Hi Gabor,
thanks for sharing your code which gave me valuable insight into many programming aspects of three.js which I had not come in contact with before.
Being a mechanical engineer and a licensed paraglide pilot, I would also expect the stabilisation and synchronisation of the satellite wing’s flight path with that of the mothership to be a major engineering challenge.
Good luck with your project!
Regards,
Chris
