YIXI / 一息 — Interactive companion demo

Current default companions: original image references converted to detailed textured 3D models using Tripo3D overseas API via the official Tripo CLI. Editable Tripo outputs, task records, Blender sources and pose/deformation reviews are retained in art-source/ and animation-study/.
Male detailed image-to-3D task: 17bfef05-6e0e-4533-9109-038cab300dad (70 credits).
The detailed male surface was fitted to the earlier 41-bone Tripo biped skeleton in Blender, with normalized four-influence skin weights. Female source/provenance is retained alongside its production files.
Default animations: idle, hello, hello_seated, sit_down, meditate. These are reviewed, baked Blender clips. Product runtime only schedules and blends fixed clips; it does not rotate limbs or invent a sit pose.
Sitting uses a human motion reference and fitted hand/thigh, foot/floor and seat contact. Quiet seated responses retain hand support. Exact support seats are included in the exported characters; the previous scene's generic stone seat is hidden.
New photo/reference customization: an explicit user click submits the image to a local backend, which calls the authorized Tripo image-to-3D API and returns a real GLB plus task provenance. No API key is included in browser code. Generated custom models are static until separately rigged, adapted and animation-reviewed; runtime does not claim arbitrary generated models already support default animation clips.
No face morph targets, lip sync or automatic universal animation compatibility is included.
