How do I get the Mesh from a 3D model?

Question

Im working with the jMonkeySDK on a 3D java game at the moment. I really need to know how I can get the mesh from my spatial (3D model). Does anyone have experience with this engine and knows how I can have access to the mesh?

I searched in the documentation and read a lot of tutorials. But I dont find a way. Hope someone can help me

Models inside jME3 are stored as Spatials , with Spatials mostly being either a Node or a Geometry .

Nodes just contain other Spatials (but can transform their position, rotation, etc) while Geometries just contain Mesh es and the Material s and other information associated with the Mesh .

The easiest way to do this is to open the model in the SDK and use the Scene Explorer window to view the layout of Nodes and Meshes . You can then determine what you need to do, as often you need to drill down through a few Nodes , find the Geometry you are interested in, and then get the Mesh from that Geometry .

Alternatively programmatically you can just recurse down through the Node structure, iterating over each child. If the child is a Node then scan that too, if it is a Geometry then get the Mesh .
