I have been through a lot of struggle and I found myself nowhere near the end. I want to make performance wise trail effect for multiple (about 10-30) objects, without discontinuous appearance, especially with thin lines. And with slow fading.
Something like http://hakim.se/experiments/html5/trail/03/.
I tried lot of approaches, and the most simmilar effect can be created with help of canvas plugin through draw line (which is awesome btw). Unfortunately canvas plugin is little performance intensive and when I tried to make lot of trails, I didnt get it quite right and performance impact on my 4-quad machine was unpleasantly high.
Recreating sprite over and over again with fading isnt good idea either, if the object moves too quickly trail will appear dotted or with unwanted spaces between sprites.
I hope someone of you guys can help me, thx in advance for responses.
Here is what I was able to do (yeah it isnt much) :
