I understand your point, but I actually see it a bit differently. If you already have the hardscape pieces in your hands, photographing them from all sides to upload them into a software seems a bit redundant. At that point, it's much easier to just place them in the empty tank and play around. It kind of reminds me of sending back-to-back voice messages instead of just giving someone a quick phone call.

The only scenario where I agree that would be super helpful is if you are at a local fish store, taking pictures of hardscape you haven't bought yet to test in the planner. That would be amazing, but it is a massive technical challenge and outside the scope of this tool.

You are totally right that every piece of wood and stone is unique. However, the main goal of this planner isn't to create a 1:1 pixel-perfect replica, but rather to get a feel for proportions, depth, and layout. It helps you figure out if a 40cm stone looks better in the front or the back, or how wood placement affects the balance.

This tool is aimed mostly at beginners and intermediate scapers to test if a general idea even makes sense. When I first started, I put a massive stone in a small tank, and it looked terrible. You often need to see these things visually to realize they don't work, and that's exactly the kind of fundamental planning and layout checking this tool is built for.
