[vtkusers] Contents of vtk-developers Digest, Vol 146, Issue 17 - RE: [vtk-developers] vtkAxesActor within VTK 7.0 and QVTKWidget

[Luis Vieira]

Hello Sankhesh,

 

That’s the point was working within the old backend. Unfortunately, I CMake  doesn’t build  automatic TDX(3D Mouse device I have) with OpenGL2  within VTK7.0 and VTK6.1 does. So I had to change to Rendering Backend OpenGL instead of OpenGl2. But is still not justifying why run out of QVTKWidget control. So, once I had built with OpenGL I will try just change the slot VTK_RENDERING_BACKEND to OpenGL2 to compile to found out and let you know.

 

Thank you.

Hi Luis,

 

I don't see anything obvious but I noticed that you are initializing vtkRenderingOpenGL i.e. using the OpenGL backend. Mind trying the OpenGL2 backend to find out whether the issue is specific to the old backend.

Hello everyone,

 

I had migrated my VTK platform from 6.1 to 7.0. I had noticed some changes, and one of those is giving me a hard work to do that is to render  vtkSmartPointer<vtkAxesActor>::New() within QVTWidget. Previously, was easily,  with VTK 6.1. Now, I am trying that and I got the Cone working/rendering well and its interactions. However, I haven't gotten absolutely nothing on my viewport from my vtkAxesActor even been shown . Following my code (C++), regarding that this works outside QVTWidget viewport.

 

I appreciate any ideas and help.
