Breast physics

[3] On occasion, this aspect of fighting games has caused particular attention, such as when the 2016 game Street Fighter V had the fighter Chun-Li's breasts move like large water balloons when she was chosen as the second player's character in the selection screen.

[6] The purpose of the initiative was to create games that deal "with an aspect of female breasts other than the fact that they're sexy and fun to look at".

In a game with 3D graphics, character models are composed of a skeleton of "bones" connected with joints and covered by a "skin" of textured polygons.

Alternatively, the motion of the breasts may be governed by custom-written software, but this is more time-consuming and therefore rarer than using springs, which are a built-in feature in many game engines.

[2] This may result from limitations of the "springs" system, which is better suited to animating rigid bodies rather than soft objects like breasts.

Mai Shiranui is a popular fighting game character who is a notable early demonstration of breast physics technology. An example of Mai's famous breast-bounce effect as seen in 2010's The King of Fighters XIII , in which her design and stance are based on her first appearance in the Fatal Fury series. [ 1 ]
