Forward rendering is the 'classic' approach to the rendering pipeline. Nowadays it is mostly replaced by a more flexible, deferred rendering approach.
I did some research and had trouble finding something specific about the history of Forward Rendering. It is my understanding, that Forward Shading evolved alongside the rendering pipeline. The pipeline provided the features for forward rendering and Forward Rendering incorporated the features of the pipeline.
I was wondering: When did a name for the classical shading approach come up and why was this specific name chosen?
