It would be amazing if ‘Stable Diffusion’ AI image generation was used to make Virtua Fighter’s kakukaku high quality polygons into a modern real 3DCG – GIGAZINE



Stable propagation image generation AI is a kind of model called “latent propagation model”, which not only generates images according to the specified instructions, but also converts low-resolution images to high resolution and improves image quality. Compress images while preserving them.

Virtua Fighter is a 3D fighting game developed by Sega that debuted as an arcade game in 1993.GraphicribbedIt is the first combat game to use graphic and express characters and stages in 3DCG models. However, in 1993, in order to animate a 3DCG character in real time, the number of character polygons must be small, so the appearance is quite wavy, based on Virtua Fighter nearly 30 years ago. It was a huge advantage of the game. You can see what Virtua Fighter actually looks like by watching the following movie.

Announced by CG artist Colin Williamson, the image of Sarah, who appears in Virtua Fighter, has been rewritten into a modern, realistic 3DCG with Stable Diffusion.

Kage (Kagemaru), who uses ninjutsu in the style of Hagakure, could not grasp a metal bowl and a chain wrapped around the forehead of Stable Diffusion, so in the modified version he looks like a masked fighter and not a ninja.

Lao Cheng is a Chinese Kimbo user. Virtua Fighter’s Lau looks rough and sloppy, but for some reason Lau’s modified face has been lowered for Stable Diffusion, giving the impression of an insanely good Chinese restaurateur. The clothes are also very beautiful, and the size does not match, which gives a somewhat cosplay-like atmosphere.


Jeffrey and Pie also look very realistic. Jeffrey is on the top left and he has a slightly strange body orientation, but his face is very realistic. Instead of a martial artist, Bai has the impression that he is ‘someone who takes just like this’.

Of course, Stable Diffusion is not an algorithm that can be corrected as desired in a single shot, so it was necessary to repeat trial and error while making fine adjustments. Apparently the most difficult thing was to reproduce clothes.

Williamson told Ars Technica, an IT news site, “If you find a good mentor, run about 50 patches and choose the most interesting one. We also give orders to artificial intelligence. “

Mr. Williamson also said that the shooter game launched in 1995 “Virtua CupCharacters are also modified using Stable Diffusion.
