Manipulating vertex data?

Is it possible to directly manipulate vertex data from python-ogre? I'm working with trying to convert the "getMeshInformation" example from c++, and I've gotten stuck on the part where (if I understand this right) you get the actual data from the buffer.

In the C++ snippet, it does this:


posElem->baseVertexPointerToElement(vertex, &pReal);


but there is no baseVertexPointerToElement function in the python binding to VertexElement that I can see. Is there another way to get at, and change, the vertex data?

thanks,

Take a look at how I retrieve the vertex data in my project. Its a slightly modified version from the PO Ode demo. Search for a method named getMeshInformation. Actually I should have creditet Andy for his code in there, sorry I will add a comment on the next commit

thanks! works great. did have to change one thing:


worldTransformMatrix = ogre.Matrix4()
entity.getParentNode().getWorldTransforms (worldTransformMatrix)


instead of using the functions to get position, orientation and scale independently; maybe those are deprecated in Ogre now?

off to spend the evening deforming meshes like crazy ...

The Grass and Bezier demos also do some creative Vertex management and there are a few helper functions that can be used..

Look at the createGrassMesh function in Demo_grass.py
