Filling a rectangular matrix area


    Apr 11 2006 | 1:21 pm
    Hello, I am generating 2 random coordinates (a,b) in a 20 x 15 matrix, and trying to fill with a random grey color the portion of the matrix whose coordinates are x > a and y < b I don't know why when i do the comparison I always get a stripe of the random color in the first column of the matrix. Can you suggest how to solve this? I think using uzi to fill a list to be crunched by jit.fill is not a great solution, so if you understand what I am trying to do, that is really simple, and have a better solution please give me an advice. Thanks a lot, Ale

      For this sort of task, I recommend using the jit.expr object or the exprfill message to jit.matrix. See the jit.expr help file and examples for more info.

      Hi, If you're trying to fill a rectangular area of a matrix, you can use jit.lcd to do it. If you're just wanting to do it on the final output, you can use opengl drawing commands to do it.
      best, wes

      thanks guys, I was stuck on that doing complicated stuff I knew there would have been an easier way for such a simple task. ale
