I need some help in the following task:
I used an image sampler to compute a grid of lines, extruded in z axis with a value from 0 to 1, extracted by the brightness filter of the image samper. I multiplied the outcoming values by 5 to see a better result.
Is there a possibility to e.g. cull every line that is smaller than 4.8? I tried around with lists and got a list defining a true and false component for the comparison NUMBER > x, but couldnt really go much further than that.
Thanks for your help!
