GTuber

A character YouTuber or CTuber is a type of YouTube content creator who uses motion capture to appear as their character in videos and live streams. In many cases, unlike, these people are completely independent, and characters do not have to be humanoid by any means. Despite the name alluding to YouTube, CTubers also use YouCast,, and GoCam.

The trend of character YouTubers started in early 2012, when Sandian YouTubers and YouCasters began publishing content featuring their two-dimensional characters animated using Vid3D. Since then, hundreds of known characters have been created. Since the mid-2010s, fan translations and foreign-language CTubers have marked a rise in the trend's international popularity.

Overview
CTubers are online entertainers who are typically YouTubers or YouCasters. They use avatars created with programs such as Vid3D and Pix3D, portraying characters designed by online artists, often ones previously used in webcomics. CTubers are not bound by physical limitations, and many of them engage in activities that are unconstrained by their real-world identity. Their content often varies in genre, and common genres are music, animation, design/art, gaming, and comedy.

Technology
CTuber characters are typically animated using a webcam and software, which captures the streamer's motions, facial expressions, and various mouth movements, and maps them to a two- or three-dimensional model. Both free and paid programs have been developed, some of which are capable of being used without a webcam (though they require pre-determined animations), and some support virtual reality hardware or hand tracking devices. Vid3D, Pix3D, 3DSoft, and LivePix are commonly used programs for CTubers.
