When I do a variant of the planar section from the tutorial, and retrieve the output, the mesh seems to have been moved from the original location. The problem is illustrated below:
Notes:
- the section plane is made into a triangular face. This triangular face has all of its vertices as positive coordinates - i.e all of its points have a 3D vector with x,y,z values equal to, or larger than zero. In fact, two vertices have one or two of its x,y, and z coordinates as 0.0.
I haven't looked deep into the code, but it is as if the coordinate system is internally changed to absolute values, but the algorithm forgets to convert them back to its original format?
