Hello,  
I’m a student trying to get in touch with shaders applied to vtk actors. Since kitware is cryptic about the topic I’m trying to get the same results as the following tutorial with vtk 8.2.0 and C++ : [http://noeskasmit.com/shaders-vtk-cel-shaded-skull-example-100-lines-python-code/](http://noeskasmit.com/shaders-vtk-cel-shaded-skull-example-100-lines-python-code/). I’m having a lot of troubles due to the differences in classes names and their functions as well as the different openGL backend.

Thanks in advance for the help 🙂

Hello,  
Thank you for your reply. Unfortunately, I’m missing some Win32 .dll in order to build those examples. Since you mentioned them, I will dig into them a bit deeper and try to understand the code in order to adapt it to the example in link I mentioned in my previous message.

Thanks 🙂
