<![CDATA[Moving meshes in Qt 3D]]>Hi, I have a 3d scene that has different objects . This objects are qml items that I have created with Mesh from .obj files. One of these objects is a mouth. I want to be able to move just the corner of the lips, not all the mouth. I don't know if there is an easy way to do be able to that. Any idea?

But Qt3D Extras includes a couple of Geometries and their corresponding Geomertry Renderers. The source code can be found here: http://code.qt.io/cgit/qt/qt3d.git/tree/src/extras/geometries. I'd suggest to study...

  • qplanegeometry.cpp
  • qplanegeometry.h
  • qplanegeometry_p.h

to understand how to implement a Geometry, and ...

  • qplanemesh.cpp
  • qplanemesh.h

for the Geometry Renderer.

Please note that throughout all the sources, classes that implement a Geometry Renderer use the word "mesh" in the class name.

Do you have any guide or example of Geometry Renderer. I'm new to Qt and I am finding difficult to program in both C++ and QML
