Ha-dou-ken pointed out a tech-heavy promotional-based piece, talking about what the
Dimps' development team went through while creating the character models for Street Fighter 4.
Buried in the story is this quote, " [...] the team members were able to model characters in an intuitive way that was reminiscent of shaping clay,
creating modeling data for over 25 characters, each with two sets of clothes."
It's interesting to see here that there were over 25 character models built, with the two sets of clothes alluding to the fighters' alternative costumes. It'd be nice to get the actual number of models built, but it could just be they're talking about Dee Jay and T. Hawk, which we know
from earlier remarks had already undergone the 2D to 3D conversion for the game.
Anyway, while this article may go over the head of anyone not versed in graphic technology, it's a solid read if you want to know about some of the behind the scenes work that happened while creating the title, sans the promotional aspect. Here's a clip.
The project began when designers at Dimps’ development workshop were handed a series of scanned sketches and drawings from Capcom’s Art Director, Daigo Ikeno. Their mission was to take the scans and create “the best quality images that can move in 3D”.
More specifically, they needed to reproduce the nostalgic movements and atmosphere of the 2D animation era while at the same time create next-generation graphics that had never been seen before. In the end, they managed to create graphics that went beyond the expectations of even the most devoted Street Fighter fan.
