 Unlike *SurfaceTool*, :ref:`ImmediateGeometry<class_ImmediateGeometry>` is an actual node. It's similar in the "OpenGL 1.x" style API,
 but it's actually designed to create content on the fly and modify it every frame efficiently.
 
-Generating complex geometry (several thousand vertices) with this node is inefficient, even if it's done only once. Instead, *ImmediateGeometry* is designed to generate simple geometry every frame.
