Draw canvas from model



  • Hi, I got model with about 15000 objects, right now I tried to draw it with rectangles but my performance is terrible. I thought there might be chance to draw them using canvas and therefore gain some performance from not calculating every width of rectange etc.
    Is this good way to handle this type of data? I want give it a try and I'm looking for some guide how to delegate as canvas and draw every rectangle inside canvas
