Detailed Description

searchableSurface using multiple slightly shifted underlying surfaces to make sure pierces don't go through gaps:

- shift test vector with two small vectors (of size gap_) perpendicular to the original. Test with + and - this vector. Only if both register a hit is it seen as one.

extend the test vector slightly (with SMALL) to account for numerical inaccuracies.

sphere.stl
{
    type triSurfaceMesh;
}

sphere
{
    type searchableSurfaceWithGaps;
    // Underlying surface
    surface sphere.stl;
    // Perturb distance
    gap 1e-3;
}
