Detailed list of contributions
''Note: QZDoom additions not listed, as not everything ended up in GZDoom. What did end up follows below.''

GZDoom

 * The postprocessing framework for GZDoom (SSAO, bloom, blur, custom post process shaders, etc.)

 * High resolution correct version of the software fuzz, for both software and hardware renderers
 * Improved dynamic light math, shadowmaps and spotlights
 * Materials (Classic, normal and specular maps and PBR textures), but not environment maps

ZDoom

 * True color support for the software renderer
 * 3D model support in the software renderer
 * Dynamic lights in the software renderer

Other contributions
Aside working on the ZDoom codebases, Norddahl's other contributions include a of the Doom Builder 2 level editor called GZDoomBuilderGL and an experimental light baking utility called ZDRay, using lightmapper code from the Strife: Veteran Edition codebase, along with porting the Ultimate Doom Builder fork of the Doom Builder 2 level editor from Direct3D9 to OpenGL, maintaining a seperate port of the game Descent called QZDescent and contributing to the EDGE source port.
