 Renderer3D.create (ForwardPipeline()) view

To plug a different shading strategy (toon, cel, custom), build an object expression over ForwardPipeline() and override Shade — the scene gather, shadow pass, and forward-pass dispatch are inherited:

 let toon =
   { new ForwardPipeline() with
       override _.Shade(gd, state, frame, activeEffect, draw) = ... }
