T-pose


In computer animation, a T-pose, also known as a Bind Pose, is a default pose for a 3D model's skeleton before it is animated.

Usage

The T-pose is primarily used as the default pose in animation software, which is then moved to create animations.
Outside of being default poses in animation software, T-poses are typically used as placeholders for animations not yet completed, particularly in 3D animated video games. In some motion capture software, a T-pose must be assumed by the actor in the motion capture suit before motion capturing can begin.

As an Internet meme

Starting in 2010 and resurfacing in 2017 the T-pose specifically has become a widespread internet meme due to its bizarre and non sequitur appearance as a distorted music plays at the background, especially in video game glitches where there would otherwise be an animation.
In a prerelease video of the game NBA Elite 11, the demo was filled with glitches, notably one unintentionally showing a T-pose in place of the proper animation for the model of player Michael Jordan. Publisher EA eventually cancelled the game due to finding it unsatisfactory. NBA 2K17 later referenced this.
In video games developed with the Source game engine, characters are in the T-pose as long as they are unarmed. It became popular among players in some modified game modes to spawn without a weapon and therefore be in the T-pose.
A fairly well known version of this meme typically involves a large group of people assuming the position, whilst the main theme of the popular video game franchise Halo either plays or is sung by said group of people.
The T-Pose is also an emote in the game Fortnite Battle Royale.
