pub const NO_VOLUME_REL: f64 = 1e-12;Expand description
A host whose enclosed volume is at most this fraction of its bounding-box diagonal cubed encloses nothing: a double-sided sheet off the axis planes sums to rounding residue (about 1e-32 for a unit sheet), not to exactly zero. A real solid is many orders above it (a 1 mm by 1 m by 1 m plate, 1e-3 m3 against a diagonal cubed of about 2.83, is about 3.5e-4).
