The Science of Video Game Boobs Jiggle Physics

Imagine how much easier high school physics would have been if your teacher had used the example of a giant pair of breasts swinging back and forth to explain Newton’s first law of inertia. Well here at Booby Pillow we feel like it’s our duty not only to entertain you with bountiful boobies but also to educate you. So let's have a serious discussion about the science behind ‘jiggle physics’.  

Jiggle physics (English)

Noun

jiggle physics (uncountable)

1. (video games) The art of portraying the bouncing or swaying of breasts on a 3D model.

You may remember Mai Shiranui, who came in at number two on our list of the Ten Sexiest Video Game Vixens, as being the very first female character to feature bouncing boobies. Back in 1992 when video games were still 2D, the developers  of King of Fighters were the first to realize they could devote extra memory to Mai’s mesmerizing mammary glands because there were less characters on the screen at one time. As technology and games progressed into 3D the science of jiggle physics was born. 

How They Get Those Boobies Wobbling 

During the development stages of a video game each character is built from a model. The model is made up of a skeleton of ‘bones’ that exist underneath the skin and clothing. Each bone is connected with a joint that gives it its range of motion. Even clothing and hair are rigged with the same spring loaded joints. Games with fewer characters or larger graphic engines can afford to devote more memory to their female character’s undulating lady bits. 

Some games may only have enough space for one joint to be programmed into the chest area. Resulting in two breasts that move in a uniform manner. But in games that have fewer characters or better engines the bosoms can have up to four joints in them allowing for individual movement and a far greater range of motion.

Multiple joints doesn’t necessarily  equal more realistic movements as many animators still struggle to depict the natural wobble and shake of a woman’s breast. But really jiggle physics is more about fueling the fantasy than being natural.  What’s reality got to do with a video game that features a character who battles demons from hell wearing nothing but a strapless bra?

When an animator is working on the motion of a character’s breasts they have to consider:

• Jiggle range- the maximum range of motion the joint is allowed to pivot

• Duration of the Jiggle- the time is takes for the movement to be absorbed after the initial motion

• Speed of the Jiggle- how fast and frequently each wave of force travels through each ta ta

The video game series Dead or Alive was the first to really capitalize on its bouncing beauties. Back in 2004 the game’s creator Tomonobu Itagaki caught a lot of slack for the amount of jiggle his female fighters had but he was unashamed of the fact. 

“I wanted to do something that would attract people’s attention as I worked on the DOA game. Of course, DOA is known for its bouncing breasts…when I applied Breast Physics to a 3D game, it was almost too much for people.”

— Tomonobu Itagaki

The DOA developers also coined the expression ‘Breast Physics’ and were the first to give players the ability to customize the amount of jiggle their characters had which was a huge selling point for the series. They eventually went on to release a game that is now infamous for having the most blatant use of jiggle physics ever made, Dead or Alive Xtreme Beach Volleyball. Which features only female characters on a tropical Island playing beach volleyball and wearing tiny bikinis that often experience wardrobe malfunctions. It was never released in the US but there are plenty of hilarious clips of it on YouTube.

• Sure the game features gratuitous use of jiggle physics as the girls jump up and down in their barely there bikinis but is that really any worse than the amount of gratuitous violence most video games have? 

After DOA popularized the ‘breast slider’ many games started allowing their players to choose the size and amount of bounce for their female characters. Even games that choose to tone down their jiggle physics often have mods that the players can add to alter the wobble themselves. A lot of people complain that the constant bouncing distracts from playing the game. To which we say, if you can’t focus on the ax wielding murderer in front of you because her gargantuan boobs are bursting out of her armoured corset, then that’s survival of the fittest. A true warrior uses every weapon they have to defeat their opponent,  including their fun bags.  

Some developers are even turning their attention towards male jiggle physics or shall we say ‘dangle’ physics. Conan Exiles is a step towards equality in that yes you can manipulate the size of your female character’s breast but you can also endow your male character with a dong the size of an elephant trunk. Then marvel as he runs around the desert naked squatting and jumping with a perfect range of dangle motion. Makes one wonder how many gym locker rooms the animators had to frequent to get that tea bag effect just right?

As booby aficionados we appreciate any science that brings us more tantalizing bounces and titillating wobbles. If you feel like you need to do some more research on this fascinating subject, here's a video of Xtreme Beach Volleyball’s wardrobe malfunctions. Happy bouncing!

The Sexiest Video Game Vixens battle It Out

We’ll never get tired of discussing the amazing assets of actresses and supermodels. But this wouldn’t be a boob blog if we didn’t mention the fact that there’s a whole other universe out there filled with beautiful women running around in bikinis firing rocket launchers. We’re talking about the gaming universe and it’s time to celebrate all that we love about our favorite female video game bombshells. From sexy demons to lady ninjas let’s dive face first into the gravity defying bosoms of these lethal vixens. 

#10 Isabela- Dragon Age II

Coming in at number ten on our list is sexy Isabela, the pirate queen from Dragon Age II. Who doesn’t love a busty pirate wench in thigh high cavalier boots? Isabela’s character is sassy, debaucherous and fun. Not only is she a roaring good time but also a kick ass dueler who can be a love interest for both the male and female protagonist. Say what? A beautiful rogue who goes both ways definitely deserves a spot on this list. 

#9 Kaine- NieR

With her insane fighting skills and unique backstory, this hot tempered intersex half-human half shade captures our hearts. She swears like a sailor while running around destroying her enemies in skimpy lingerie and black kitten heels. Kaine makes mummy bandages look hot and cracks us up everytime she starts running her trucker mouth.

#8 Camilla- Fire Emblem Series

Two words: Armored Corset! Camilla is famous for being one of the bustiest characters in the gaming universe. This elegant and sultry babe is also a ruthless and bloodthirsty warrior who likes to store important items in her massive cleavage. We love making her pull things out of her storage chest. Where’s that darn map? We also enjoy it when the player runs into and bounces off her bountiful boobs.

#7 Rayne- Bloodrayne

This alluring red headed dhampir (half vampire half human) is the main protagonist of the Bloodrayne series. She is sadistically seductive in her black and red leather dominatrix outfit. We love her bold snarky attitude and fondness for profanity. Not to mention her terrifyingly lethal tendencies. This one likes to play with her victims first, and derives pleasure from seeing their fear and pain. She makes our blood run hot and cold at the same time. 

#6 Morrigan Aensland- Darkstalkers

Everyone’s favorite succubus. We’re not the only ones bewitched by this sultry seductress, Morrigan has millions of fans worldwide. With her beauty, confidence and sexy playful nature, she’s become Darkstalkers most famous character. Morrigan has surpassed her video game origins and is now one of Japan’s most recognizable characters. Spawning a whole host of succubi media, manga, pornographic films and animated series. Her signature green hair, ample bosom and purple tights can be seen all over the cosplay world and we like it. 

#5 Chun Li- Streetfighter

No list would be complete without paying respects to the very first female character in a fighting video game. Chun Li has been using those sexy thighs to kick butt since 1991. Countless boys have gone to bed staring at posters of Chun Li on their walls in her cute little qipao dress and matching buns. This courageous Interpol officer will always be our first video game crush. 

#4 Ivy Valentine- Soul Calibur

Ivy Valentine’s breasts are so big they’ve become infamous. Many critics claim that video games have gone too far, and the breast sizes are getting indecent. Namco’s response?  Make em bigger and run an ad campaign featuring nothing but an image of her glorious cleavage and the words “Go big, or go home!” written in Japanese across her chest. This busty combatant takes some serious skill to play though and is more than just her skimpy bondage gear and voluminous breasts. Ivy’s a fierce fighter with Machiavellian tendencies. 

# 3 Quiet- Metal Gear Solid: The Phantom Pain

This elite assassin doesn’t need words to enthrall us. Sure there are bigger racks out there but Quiet’s ability to murder while dressed only in combat boots and a black bikini have earned her a top spot on this list. Just watch her playfully rolling around in the rain or taking a shower  and you’ll be just as obsessed as we are. Quiet may be silent, but she sure is deadly. 

#2 Mai Shiranui- The King of Fighters

The ‘Knockout’ Ninja has been hypnotizing us with her signature ‘kunoichi’ or bouncing fighting style since 1992. Mai has become one of the absolute most popular female characters in the fighting game genre worldwide. This cheerful yet temperamental ninja was the first to feature floating boobs. Something that has been highly criticized over the years. Not by us, or any of her legions of loyal fans who threatened to boycott King of Fighters when they thought to release a version of the game without her. Thousands responded by chanting “No Mai No Buy!” and we agree. 

#1 Lara Croft- Tomb Raider

By today’s standards Lara Croft may not seem that well endowed but back in 1996 when Tomb Raider first came into our lives, she was the epitome of female sexuality. Proving that a tight tank top and pair of short shorts can be just as titulating as bondage gear. There’s no denying her spot at number one. Lara Croft has graced the cover of more magazines than any supermodel or actress and is by far the most successful selling female video game heroine of all time. This adventuring archeologist has raided our dreams and stolen our hearts!

We spent many difficult hours playing with these women trying to decide who should be on the list. Who’s your favorite?
