Tiled Forward Shading
Markus Billeter, Ola Olsson, and Ulf Assarsson
4.1 Introduction
We will explore the tiled forward shading algorithm in this chapter. Tiled forward
shading is an extension or modification of tiled deferred shading [Balestra and
Engstad 08, Swoboda 09, Andersson 09,Lauritzen 10, Olsson and Assarsson 11],
which itself improves upon traditional deferred shading methods [Hargreaves and
Harris 04,Engel 09].
Deferred shading has two main features: decoupling of lighting and shading
from geometry management and minimization of the number of lighting computa-
tions performed [Hargreaves and Harris 04]. The former allows for more efficien ...
