Text output in VTK (2D and 3D)

*Purpose: VTK supports both 2D and 3D text rendering. For 2D, it usually uses vtkTextActor. We can control its font, shadow and display position (in 2D screen coordinates). For 3D, many possible options can be used. One favorable option is to use vtkVectorText with vtkLinearExtrusionFilter. It gives high-quality 3D text rendering.

(Please first follow the VTK installation guide to build VTK from source)

There major VTK classes are used in this demo: vtkTextActor, vtkVectorText, vtkLinearExtrusionFilter.

Can you help me create a CMake config file for this simple project? I'm just barely getting started with VTK, and I'd like to try out your text example on OS/X, without access to Visual Studio.

Thanks for your help,

Nevermind, I ended up getting it to work with this in my CMakeLists.txt file:

cmake_minimum_required(VERSION 2.6)


INCLUDE (${CMAKE_ROOT}/Modules/FindVTK.cmake)
LINK_LIBRARIES(vtkRendering vtkGraphics vtkImaging vtkIO vtkFiltering vtkCommon )
LINK_LIBRARIES( vtkWidgets )

ADD_EXECUTABLE(VTK3DText demo_vtk_text_output.cpp)
TARGET_LINK_LIBRARIES(VTK3DText vtkIO vtkFiltering vtkCommon vtkRendering)

I may be including some stuff that isn't necessary in there, but it works, so I'm happy. I realize this post is pretty old now, but it came up first on google for "vtk 3d text".

A refractometer can pinpoint the percentage of sugar in other confections as well, including
jams, jells, candy, ice cream and gelees. well, I hear they are doing great things with prosthetics these days.
I do think a sheep's milk cheese is preferable, however, due to its relatively strong flavor and compatibility with

Disaster comes often because the people and societies

to blame, how about video games.

I'm impressed, I have to admit. Seldom do I come across a blog that's both equally educative and amusing,
and let me tell you, you've hit the nail on the head.
The problem is an issue that too few people are speaking intelligently about.
Now i'm very happy that I came across this in my hunt for something concerning this.
