The kind of bagel that ruins lesser bagels for you.
Summary
This technical article by Sean Barrett, the primary author of the core rendering technology for Thief: The Dark Project, provides an in-depth analysis of the 3D software rendering technology used in the 1998 stealth game. The article explains how the game was developed during a transitional period when 3D hardware acceleration was emerging, but due to development cycles, Thief remained a purely software-rendered game. Barrett details the technical challenges, rendering techniques, and architectural decisions behind the engine, which was later modified by others to use 3D hardware acceleration for System Shock 2 and Thief 2. The content focuses on the technical implementation, performance considerations, and historical context of late-1990s game development technology.
Key quotes
· 3 pulledThis was just as 3D hardware acceleration was taking off, so due to the development cycle it didn't use hardware acceleration; it was a purely software-rendered game.
I was the primary author of the core rendering technology in Thief (although I didn't write the object or character renderers), as well as some related bits and pieces.
The same rendering engine, modified by others to use 3D hardware acceleration, also did the rendering for System Shock 2 and Thief 2.
