  1. hi Daid, Recently, i research the Cura engine, which is a great work. And i have one question. When merge the redundant point, you use the ' int hash = ((p.x + MELD_DIST/2) / MELD_DIST) ^ (((p.y + MELD_DIST/2) / MELD_DIST) << 10) ^ (((p.z + MELD_DIST/2) / MELD_DIST) << 20);'. Could you tell me the logic of this? Thanks for all your hard work. Cheers, neo
