The phrase identifies readily accessible, pre-built digital representations of books that are designed to move or display animation, and are available at no cost. These models are commonly utilized in a variety of digital projects, including video game development, animation, and digital marketing.
The availability of these resources significantly reduces production costs and accelerates project timelines. Designers and developers can leverage these models to create visually engaging content without the need for extensive original modeling work. Historically, acquiring such assets required significant investment, making accessibility limited.
