The 45 VSTRIP vertices captured off the i860 sort back into an exact 9x5
model-space grid (x,z in even 2-unit steps, y = height at every node; all
45 cells filled). cap7's death-camera views it nearly edge-on, which is why
the raw screen projection looks like a folded sliver. gridsurf.py rebuilds
the true grid connectivity (2 tris/quad) and shades it from the firmware's
own per-vertex normals -> a clean solid surface. render-readout.html now
leads with that true-3D reconstruction and shows the grazing projection +
wireframe as "how the death-camera saw it".
Also resolved a long-standing red herring: the (1,1,10,10) extent bounds
that earlier sessions chased as the "empty-bins bug" appear identically in
the working frame -- they're the per-frame marker rect, not the geometry.
