3D Engine Design

Welcome to the 3D Engine Design section of this edition of GPU Pro. The

chapters you will find here cover various aspects of engine design, such as quality

and optimization, in addition to high-level architecture.

First, Pascal Gautron, Jean-Eudes Marvie, and Ga¨el Sourimant present us

with the article, “Z

Culling,” in which the authors suggest a novel method to

optimize depth testing over the Z-buffer algorithm. The new technique adds two

“depth buffers” to keep the early-Z culling optimization even on objects drawn

with states that prevent early-Z culling (such as alpha testing).

Next, Dzmitry Malyshau brings his experience of designing ...
