Good luck.
But I want to add. I personally would like a double option for 3d. All 3d Plugins so far have been canvas renders based. In which the plugin is built to render worlds. I would really like to see Render To Texture and use the Texture/Image. That way I have more options. So i'm not looking so much as a world renderer, but more of an object renderer.
I had this in mind. I started out with it actually. I will most likely include it too. But the performance hit is quite massive because I have to draw the 3D onto a 2Dcanvas and then create the texture for the "sprite" and apply it. And that 60 times per second. I did a lot of testing and it gives very big performance hits. However I will still include it once I am done
Here is an example of how it has to work.

You can see how much resources the 2D texture function uses. And this is not even applying it to a Sprite!
