wireThickness top-level constant

double const wireThickness

How thick a wire is, as a fraction of the mesh's own bounding diagonal.

Relative rather than absolute because the same number has to read on a two-metre character and a two-centimetre bolt, and neither knows about the other. Measured by eye against case4.glb's robot at 512 × 512: a thousandth of the diagonal is about one pixel there, and this is three of them — thin enough to leave the surface visible between wires, thick enough to survive the rasteriser at a quarter that size.

Implementation

const double wireThickness = 0.003;
