id Releases Open Source Wolfenstein 3D for the iPhone

An anonymous reader writes "id Software has released a port of the classic Wolfenstein FPS to the iPhone. Some of the coding was done by John Carmack himself, who also used original code combined with new code from Wolf3D Redux. The original code was open sourced years ago, and enthusiasts have been updating it, which made the port considerably easier for id. It's available in the iTunes App Store, but the source is available for free at id's website." Carmack also posted a detailed writeup about the decision to bring Wolf3D to the iPhone, including design notes and a few snippets of code. At the end, he says, "I'm going back to Rage for a while, but I do expect Classic Doom to come fairly soon for the iPhone." Kotaku got a chance to try the game at GDC: "It's not just a good reproduction of the original, it seems better."

Graphics quality

[Mprx]

The graphics are crisp, intense duplicates of the original.

But from the screenshot we can see that both the sprites and the textures have been filtered. Filtering the textures is no problem, but the sprites are "pixel art" - they are designed around the pixel boundaries to pack more detail into a limited resolution. It's the same principle as manually hinting fonts. The only acceptable scaling method for pixel art is unfiltered "nearest neighbor" scaling, as used in the original game. This new version is not "crisp", it is an ugly blurred mess.

I think the Wolf3D Redux guy made a big mistake...

...by not forwarding his email to his current address.

"I sent an email to the Wolf 3D Redux project maintainer to see if he might be interested in working on an iPhone project with us, but it had been over a year since the last update, and he must have moved on to other things."

He'll probably learn about the missed opportunity by reading slashdot...
