[Ves] Rotating 3D Model On a Single Axis Alone

[shamsudheen]

Thanks again for your quick and effective reply.

Importing #include <vtkTransform.h> in my VES project giving an error as vtkCommonTransformsModule.h not found in vtkTransform.h.

There is no VES classes returning vtkTransform pointer to me.

Could you please explain little-bit.


Note:

Actually I have done the single access rotation in X axis without effecting/reseting the Y-Axis.

I have just modified the currentTranslation.x, currentTranslation.y with my own logic in the below method/guesture and it worked fine

 handleSingleTouchPanGesture  self->renderer.app->handleSingleTouchPanGesture(currentTranslation.x, currentTranslation.y);

However Im looking for the Communication with VES and VTK (iOS and Windows).

My plan is to rotate a 3D model in widows pc while iOS app rotate the same 3D model in iPad.

So Im unable to use currentTranslation.x, currentTranslation.y in VTK (windows)

The only way to get the rotation angle.

So I have looked for another method vesActor->setRotation(vector);. However it resetting my Y axis previous rotation state while rotating X-axis.


Note: have just used   bool loadDataset(const std::string& filename); method to load my 3D file.this is a vesKiwiViewerApp.h class method.

 
Thanks.
