Masking shapes
Dec 6th, 2007, 3:14pm  
Is there a good way to mask drawn shapes? I know there is mask functionality in PImage, but I need something that will mask out certain parts of a given shape. What I'm specifically working on is a vertex mesh that I'm using to simulate water. At the current time though its constrained as a rectangle, and I would like to make water like edges to it.

Any ideas on how to do this would be great,

Thanx

Hi, do you want do more than what you can do with the texture() functions ? This allow you to put a texture to a shape defined by vertex.

Thanks for the suggestion, but textures wont work since the vertex shapes is constantly changing in a wave pattern (a sine curve). I need something that could set up a perimeter, which would render any shapes crossing it invisible somehow.

Anyone have other ideas?

hi. so, why would vertexes not work? also mask() could do what you want. but it's quite slow when used every frame. I guess I just don't really understand what you're asking Wink
