[vtkusers] Graphing points

[Bill Lorensen]

Barney,

Your experience with VTK will be much more pleasant if you use cmake.

Without cmake, you can use VTK, but, unless you are an expert with Visual
Studio, you will become frustrated and delay your VTK experience.

Please try cmake and ask questions to get started if necessary.

1) Create a directory for your source code, e.g. call it MyVTK. Add your
first example here, perhaps the one I suggested. Also, place the suggested
example source code here. Call it ReadTextFile.cxx.
2) Create a directory for your binaries, e.g. call it MyVTK-build
3) Run cmake (probably the cmake gui). Tell it which generator you want (the
same when you built vtk). Click configure (or something similar). It might
ask you where your vtk binary directory is. Select that. Configure and then
Generate.
4) Go to the MyVTK-build directory and start VS with the solution file.
5) Build all and you should be all set

Bill
