Lineborn

Description

Lineborn gives birth to worlds from lines. Draw on a canvas at real-world scale inside a 3D world, and a few lines can become an object, a life-size character, a place, or the beginning of an entirely new world.

Draw a character and bring it to life. Tripo P1 transforms the sketch into 3D; Lineborn checks the model for rigging, auto-rigs compatible bipeds and animates them with the author's Mixamo-compatible animation library. The result doesn't appear in an asset viewer: your character walks out of the page, at the scale you drew it. With the OpenAI Realtime API, you can immediately talk to your new 3D friend.

Draw a place and the transformation goes the other way: the lines become an image, the image develops depth, and the canvas becomes an opening into an explorable world. What began as a drawing becomes somewhere you can enter.

Lineborn is a gift for anyone whose imagination exceeds the world they were given. The author wanted drawing to be more than a way of representing an imagined thing, with the line itself as the beginning of a reality. The individual technologies behind these transformations already exist; Lineborn changes their relationship. The drawing is spatially authoritative: its composition and physical scale carry forward as imagination crosses from 2D into 3D. A line becomes a body. A line becomes a place. A drawing becomes a door.

Lineborn also uses Jupiter's 3D display to bring Tripo-generated characters out of the flat screen, and MediaPipe hand tracking lets you reach toward them and interact in space. It brings together and extends several of the author's earlier projects, including AI3D Canvas, AI3D Desktop, Napkinmatic 3D and Wanderlust "Walk into Paintings".

How Tripo was used

Tripo is Lineborn's bridge from imagination into interactive 3D.

• Sketch to 3D: Tripo P1 turns a drawn character into a 3D model, and sketches and generated images flow through Tripo image-to-3D to become reusable objects and characters.
• Bringing characters to life: characters then pass through Check-Rig, AutoRig-Biped and a Mixamo-compatible animation library.
• Live nodes: rather than ending as exported assets, Tripo outputs become live nodes in the author's Aperture creation graph, ready to inhabit World Labs worlds, become AI friends or appear in movies.
