P_Matte
Just my take on the always-so-popular matte extraction tools from images containing position data in any given coordinates (P pass, worldP, position, pRef, ... you name your flavour)
This one lets you choose between a sphere or a cube-shaped matte. There's controls for scaling, rotation, skewing and options to tweak the amount and type of falloff.
One of the main focus of P_Matte is to keep it simple and fast, so hopefully it should have a good interactive response while sampling the image.
Hope you like it :)
