[Insight-users] TriangleMeshToSimplexMeshFilter high memory usage

[Niccolo' Camarlinghi]

Dear all,

I'm trying to extract a surface of a sphere of radius 250 px in an image
of 515*512*512 px and calculate volume and area of this object(this kind
of problem should reproduce the computational cost of working with the
pleura surface extracted from a lung CT ).

My procedure is divided in 4 steps



0) Creating  the sphere
1) I extract the surface using BinaryMask3DMeshSource 
2) I convert the triangular mesh obtained from the previous step to a
Simplex mesh using TriangleMeshToSimplexMesh 
3) I evaluate the volume and the area of this simplex mesh using 


My problem in the second step the memory consumption is very high (the
process uses swap on a 64 bit machine with 4 gb of ram ).
My question is: Is there any way to reduce the memory impact of the
TriangleMeshToSimplexMesh filter ?



i allegated the code i'm using 




Best Regards

Niccolo' Camarlinghi
