[vtkusers] Comput the area contained by a contour (VTK C++)

[Belaroussi, Boubakeur]

Hi Rodrigo,

For 2D contours, you can use the following pipeline:

1. Transform your contour points into triangles, using vtkTriangleFilter, which creates triangle polygons from input polygons and triangle strips
2. Then, to get the area of your contour, among other features, you can use the vtkMassProperties filter, which estimates volume, area, shape index of triangle mesh.

Hope it helps
Regards,
Bouba

Subject: [vtkusers] Comput the area contained by a contour (VTK C++)

Hello everyone,

I was wondering if any of you know a method to compute the area cointained by a figure or maybe something like the contourwidget which shape can be changed at will.

What I need -d be some kind of implementation or code or guide on how to perform that math operation, similar to the distance widget but what I need to compute now is area.

Id really appreciate any kind of help
