How is "Trails" implemented

Post by sefreso »

Hello,

I would like to port Resolume's "Trails" video effect into a GLSL plugin.

I have been looking online for tutorials but can't find the right search keywords.

I don't really know where to start.

Would anyone outline the main steps in producing the Trails video effect?

Thanks!

You need to retain a copy of the last rendered frame.
So keep a copy and perform a blend with the new Frame.
