Coming soon

It's good that you mention the option to configure the hull model per station. I had already thought about implementing it, but put it aside because I wasn't sure whether it would be used in practice. My estimate for the implementation with Claude: 30 minutes.

Plan: Every station is classified from its own splays and from how far they reach toward each neighbouring station:

LRUD — fewer than 3 splays. The station contributes only its LRUD cross-section.
CONCAVE — its splays meet those of every neighbour: for each shot, the station's own reach plus the neighbour's reach covers at least 150 % of the shot length. The station gets its own concave hull.
CONVEX — enough splays, but on at least one shot the two fans do not meet, so unmeasured space remains along that shot.

Reach is the largest projection of a splay onto the shot axis, divided by the shot length, counting only splays within 45° of the shot direction — a splay fired sideways does not cover the way to the neighbour, however long it is.

The geometry of a shot follows from the types of its two ends:

LRUD – LRUD classic LRUD tube
CONCAVE – CONCAVE nothing: the two point hulls already overlap
anything else one convex hull spanning the shot

Each CONCAVE station additionally emits its own concave hull — exactly once, no matter how many shots meet there.

For the convex shot hull, each end contributes differently: a CONVEX end gives all its splays, an LRUD end gives its LRUD cross-section as a rounded ring, and a CONCAVE end gives only the ring of splays roughly perpendicular to the shot (60°–120°).

Data table for large surveys (100,000+ survey lines) revised:

All edits (new, insert, delete, cut, drag & drop) run orders of magnitude faster
Undo/Redo now only saves the changed rows: the full history (50 steps) remains available and runs in seconds
Cell edits confirmed by mouse click are now also undoable

Is it possible to make the convex/concave decision based on a configurable number of splays, e.g. 12.

0–2 LRUD
3–11 Convex
> 12 Concave

The cause is an OutOfMemory error in the Undo/Redo function. I will work on it.

Technically speaking, the orthogonal view is a perspective view from a distance. I will reduce the distortion by a factor of 5.

Revised lighting for the volume display (Ambient Light):
- The light source no longer rotates with the model
- Slightly darker shading for more depth

Zip-file (19.07.2026: 20:28:26) looks OK: 26.1.0

We now have two options:

1) Convex hulls around the rays of the two points of a survey line (few rays à la Golden Rules)

2) Concave hulls around the rays of the survey points (scan- and quarry-friendly)

I was actually satisfied with the clear rule of the convex hull around the rays of the two survey points of a survey line. The question is whether there is another rule. Perhaps the option to display only the convex hulls of the survey points.
