Texturing Video in dynamically made PShape

ArunatpalC

I have been trying to identify libraries,using which you can map into irregular objects in processing.(Any leads ?)

Unable to find one, I went ahead to make a small version for my project. Right now I control the (u,v) coordinates to make an Illusion of water level moving up and down. It works fine, but I want the help of the community so that one can texture videos and also maybe dynamically control the points after being mapped.

/*Instructions: 

1.MAKE A SHAPE WITH THE POINTS
2.PRESS 'E' TO TERMINATE AND MAKE THE NEXT SHAPE
3.ONCE DONE WITH ALL SHAPE PRESS 'E' AGAIN
4.PRESS 'Z' TO LOAD THE TEXTURE AND PLAY WITH THE MOUSE VALUE
