Hello All, i am new to the jitter world and i stuck on this problem:

i want to draw an plane via jit.lcd and want to use this shape as mask for an scrolling jit.gl.text2d object. The text should be only visible inside the area covered by the plane.

i pasted what i have so far, but now all methods i tried failed (yes i am an beginner ;)

any help appreciated... Joa
