<div dir="ltr">Dear all,<div><br></div><div>I need to throw a couple of questions about spatial objects:</div><div><br></div><div>1. Is it possible to find the *relative complement* of one spatial object in another (<a href="http://en.wikipedia.org/wiki/File:Venn0100.svg">http://en.wikipedia.org/wiki/File:Venn0100.svg</a>).</div>
<div><br></div><div>2. If so, would the method IsInside() correctly work even if the result is not connected or is not convex?</div><div><br></div><div>My problem is as follows: I read a freesurfer's mesh of the white matter, and I want to remove the CSF part. For this, I would compute the relative complement of the CSF in the WM. Afterwards, I would need to check if certain points are inside the mesh.</div>
<div><br></div><div style>Of course, I could use the binary mask from freesurfer, but that would add an extra input to my application, that I'd like to avoid when possible.</div><div style><br></div><div style>Thank you so much in advance.</div>
