The phrase refers to digital, three-dimensional representations of dragons designed with movable joints or sections. These models are structured to allow for posing and animation within computer graphics software. Furthermore, the accessibility of these models is often facilitated through cost-free acquisition, making them appealing to a wide range of users.
The availability of such resources is beneficial for hobbyists, students, and professionals involved in animation, game development, and 3D printing. It lowers the barrier to entry for projects requiring complex character models. Historically, creating articulated 3D models required significant expertise and resources; the presence of freely available options democratizes this aspect of digital content creation.
