Deferred Attribute

Interpolation Shading

Christoph Schied and Carsten Dachsbacher

3.1 Introduction

Deferred shading is a popular technique in real-time rendering. In contrast to

a traditional rendering pipeline, deferred shading is split into two phases. First,

the geometry is sampled and stored in the geometry buffer, which serves as input

for the second phase where the shading is computed. Thereby, the complexity for

shading is decoupled from the geometric complexity, and furthermore advanced

geometry-aware screen-space techniques may be employed. However, deferred

shading does not play well with multi-sample antialiasing. Multi-sample antialias- ...
