Soft Edge / Edge Blending
May 13th, 2009, 10:26am  
hello there!

i want to make a projection with 2 beamers, where the both screens are soft edged, meaning both screens fade out at one side and overlap when projected.

i have my content now in an offscreen buffer (GLGraphicsOffScreen from codeanticode), but i have some troubles getting correct alpha masking (yes, i know about the thread "PGraphicsOffscreenGL + Alpha-Mask?"). but either my texture is completely masked, or completely unmasked.

could someone provide me some sample code?

and: is there a way to do all the processing (i mean of the edge blending) solely in a shader?

thanks in advance,

micha
