Flat renders don't sit true on a curved wall. These two instruments work out the geometry and the alignment before a single pixel is fitted.
Set panel count, radius and wall height. Read the render arc, aspect ratio and edge stretch live. Walk inside to check the curve.
Lay the mesh grid against the skin grid and pre-warp one to meet the other. Export the parameters the fitter reads.
Load the fitted panels and cap, then walk inside. Check that the seams close, wrap the cap live, and compare fitted against raw.
