I’ve used a lot the Jit.charmap to manipulate color (with 4 jit.fill to planes- 256 slides 0. - 1.) How to get it wit a Jit.gl.slab or some other from GL group? I started with a jit.movie , charmap ,slab (to group GL) and videoplane. (yes I know its probably by multiply matrizes, but...? I liked the Jit.traffic too. What about something in GL?). Thanks to help.
