We'll explore the role of physical spaces and objects in metaverse creation. Using 3D scanning technologies, one can easily create an editable digital twin of any space, person, or object. With NVIDIAās Omniverse tools, especially Audio2Face, itās possible to animate custom avatars with their own voices and intelligence. We'll share the technical and creative process developed for the speculative sci-fi world we call Little Martians, which combines language models, text-to-speech, 3D scanning, 3D animation, and custom AI image generation.
