int numVertices = getNumVertices();
if (numVertices == 0) gdx_log_error("gdx","No vertices defined");
float_buffer verts = vertices->getBuffer();
bbox.inf();
VertexAttribute& posAttrib = *getVertexAttribute(VertexAttributes::Usage::Position);
int offset = posAttrib.offset / 4;
int vertexSize = vertices->getAttributes().vertexSize / 4;
int idx = offset;
