I'm wondering why the large area in the middle of the right wheel is also edited. Hope you can give some advice.

1. In the first example, I guess certain stroke pixels go beyond the boundary of the wheel (though not distinguishable by human) and are mapped to the surface of the yellow blocks, which leads to the color leakage to the background.

2. In our implementation, all points in one brush stroke are recognized and unified to a cube with rotation and translation. A circle stroke should be decomposed into several smaller line strokes theoretically, but technically we didn't implement that for the GUI.

So that's why you see the red leaks to the horizontal bar of the right wheel in second example.

I am sorry but we didn't (and never tried to) make the GUI perfect or reach product-level. Note that the GUI is just to show the possibility and ability of our pipeline proposed in the paper. As long as there's nothing too wrong, I think it's OK.
