So I spent all of today making this patch to detect when a point is inside a specific shape in a 2D plane. This is useful for any type of 2D interaction that needs to have objects respond to the location of a finger, mouse, pen, light, etc… You can create multiple shapes that are individually triggered when touched. I do this by polling the color of the x,y point on the LCD object and assigning RGB values to indexes.
Right now I’m using it to create a virtual drum kit to be played with kinect.
Would love to do this in 3D but my skills with jitter are limited!
