![header830](https://forum-defold.b-cdn.net/uploads/default/original/3X/c/d/cd56eb3867cc2859c573cef6374b70d235eab46a.png) I’ve been testing this for a long time, and it should be quite stable. However, due to a major refactoring, it is best to consider this a Beta version. DAABBCC 3D v1.0 is based on [DAABBCC 2D version v3.0.1](https://github.com/selimanac/defold-daabbcc/discussions/13), so it includes all the same functionalities. Manifold generation and raycasting have been completely rewritten. They are a bit more expensive than the 2D version. **Note:** Unfortunately, there is no built-in way to get the size of a model using Defold. You might need to use external 3D tools or use a dummy 3D object to estimate the size. But luckily, there is a [PR waiting](https://github.com/defold/defold/pull/9946). I hope that soon we won’t even need to get/set the size manually. I’m still preparing examples, but it is quite straightforward. ## Source [https://github.com/selimanac/defold-daabbcc3d](https://github.com/selimanac/defold-daabbcc3d) ## Discussions & Release Notes > **[selimanac defold-daabbcc3d · Discussions](https://github.com/selimanac/defold-daabbcc3d/discussions)** > > Explore the GitHub Discussions forum for selimanac defold-daabbcc3d.

Yet another example project for daabbcc3D. This one is almost complete as it is; I don’t want to go too deep into it (I’m a hard core gamer, look what I’m doing!!! 😱 ).

I love it! Please release it so others can play around with it! Are you open to do more things like this if you get some funding? ---

It is not perfect, not even close, but I will share it in a couple of days(I guess), as always on GitHub with the source. > [@britzl](#): > > Are you open to do more things like this if you get some funding? Why not! But I’m already doing it without funding 🙂 ---

It contains many issues, but those issues are not related to this library. A few notes: - Samples are set to 2, which means anti-aliasing is enabled and set to 2. If you experience any performance issues, don’t forget to turn it off from game.project file. - No touch support, and the GUI is not compatible with mobile. Basically, there is no mobile support. - You can place anything anywhere. You can even do something like this: 🤣 ![Screenshot 2025-02-16 at 19.59.24](https://forum-defold.b-cdn.net/uploads/default/original/3X/b/a/ba6d84a121180ffe89885c463c281118ce40a94a.jpeg) ---
