Examples of VertexBuffer

com.jme3.scene.VertexBuffer
A VertexBuffer contains a particular type of geometry data used by {@link Mesh}es. Every VertexBuffer set on a Mesh is sent as an attribute to the vertex shader to be processed.
Several terms are used throughout the javadoc for this class, explanation:
- Element - A single element is the largest individual object inside a VertexBuffer. E.g. if the VertexBuffer is used to store 3D position data, then an element will be a single 3D vector.
- Component - A component represents the parts inside an element. For a 3D vector, a single component is one of the dimensions, X, Y or Z.

    private void renderMeshDefault(Mesh mesh, int lod, int count) {
        VertexBuffer indices;


        VertexBuffer interleavedData = mesh.getBuffer(Type.InterleavedData);
        if (interleavedData != null && interleavedData.isUpdateNeeded()) {
            updateBufferData(interleavedData);
        }


//        IntMap<VertexBuffer> buffers = mesh.getBuffers();
//        SafeArrayList<VertexBuffer> buffersList = mesh.getBufferList();
