Summary0014820: Misleading documentation in vtkCamera::GetFrustumPlanes
Descriptionhttp://www.vtk.org/doc/nightly/html/classvtkCamera.html#a63ac225662fc7b81628366a7b3b7096c [^]

Hello, I found that the documentation is misleading, because it tells that the order of the planes is:
left,right,bottom,top,far,near

Debugging VTK revealed that the actual order is
left,right,bottom,top,near,far

This is how I verified that it is wrong: I created 10 equidistant points from the camera position (outside the frustum) to the focal point (inside the frustum) and I checked the signed distances of the last and the second last planes.

The second last remained positive (far plane, oriented inward) while the last went from negative to positive. That is the behavior of the near plane! the first point is the camera, which is outside of the viewing frustum, therefore it has negative sign, the last is the focal point for which the signed distance was positive.

Please fix+comment :)

The software behaves against what is specified -> incorrect functionality
