Each view contributes different shape evidence
The front and back views help describe width and outline across the body. The two side views add depth and profile that cannot be recovered reliably from the front alone.
Using all four views does not remove uncertainty, but it gives a broader outside record than a single photograph.
How Pip Body Scan builds the 3D body
Nothing is sent until you tap "Agree & start scan". Then the four photos go through Pip's server to Meshy, which makes the textured 3D body. Copies with the head masked, plus your height, weight, age range and sex, go to OpenAI for the estimates.
Meshy's copy is deleted once the body is saved on your iPhone. Separately, the phone fits its own body model for the measurements and outlines. It usually takes 2 to 4 minutes, and you can leave the app while it works. Pip uses the normal camera, not LiDAR or depth.
Know what can affect the result
Loose clothing, a changed pose, hair covering the outline, camera distortion and inconsistent framing can all affect a photo-based estimate.
Use it for personal progress comparison, not as a substitute for a clinical scan, tape measurement, diagnosis or treatment decision.
Keep this check-in repeatable.
- Use all four views
- Keep the full body visible
- Match clothing and pose
- Read the consent screen
- Treat the model as an estimate
