<br>
I'm looking for a way of interoperability between CUDA and VTK. More<br>
exactly, what I need to do is display in VTK an image I compute with CUDA.<br>
To do so, I thought about using the CUDA/OpenGL interoperability. However, I<br>
have not found a way to modify a VTK texture outside VTK. I read the<br>
documentation about the vtkOpenGLTexture class but did not understand how<br>
that could help me.<br>
Any idea?<br>
<br>
Thanks,<br>
