Hi,
I'm trying to make a wipe transition using some 'bubles' (particle system) as an alpha mask for an image to show the underlying image.
This has to run in 1360x768 and I'm really having problems with my framerate.
I've tried writing to both a P2D and a JAVA2D off-screen buffer which is ok, but when I add some other graphics everything slows down dramaticaly.
So what I'm trying now is to use OpenGL to do the heavy work, but I can't get an alpha mask to work. That is I can get a JAVA2D buffer to mask using OpenGL but the framerate is redicolous.
I've started to have a look at the codeanticode libraries, but which has helped on the framerate using off-screen buffer in OpenGL, but I can't get the alpha to work. I've tried with the buffer.background(0,0) on the GLGraphicsOffScreen object, but it just shows up as black.
I appologize for my rambling, but I'm getting close to desperation here.
