The colour assigned to the splays belong to the station and therefore doesn't give much information about the Z value of the splay end, primarily in Plan mode and Volume.

From the splays, maybe the splay lines could have a colour graduation: from the station color to the splay end depth color. However, this might be not efficient in caves with significant altitude variation as the color variation is likeleky to be a lot less significant, but still it should be an option. Maybe a second display option could show the Z value of each splay (and maybe the station depth as well).

For the Volume visualisation, could the volume walls have a vertical color graduation instead of "just" the station colour?

Is this mainly a problem at small caves with few lines?

JavaFX lines could have only one colour, but no graduation. Volumes, I think, can get a graduation be using textures.

Apropos textures: a 32x32 bit texture looks much more interresting than graduated colours.

I find it's more a problem when I have lots of splays at the same station and/or several neighbouring stations, but even with a smaller number of splays I'd like to understand what is what without having to jump back and forth between Plan and Section and Perspectives.

If the line can only have one colour, maybe one option could be to link the colour of each splay to its Z value, instead of the station Z value. And to address the largest elevation difference by having a parametrable colorscale that could be set with custom min/max (and reset to default min/max). This could help in interpreting splays at any scale: chamber, whole cave, several caves.

The texture looks nice for Volume but... Colourscale remains a great tool for analyses.

Today colouring depends on RefZ of RefStation (very old code).

Here is an example depending on Z of Station.



Or better the median of the line: (RefZ + Z) / 2 ?

Z of Station would best in my opinion.

Looks really nice on your example, but on my side it gives some strange results.

I thought two depth colours per volume are enough (Station and RefStation).

Now I calculate the depth colour for every edge (i.e. 64) at both sides of the volume. This looks much better.

Perfect! thanks

Die neue Darstellung nach Tiefe finde ich super.

Eine kleine Kleinigkeit ist mir noch aufgefallen. Der Deckel des ersten Messzuges am Eingang einer Höhle wird nicht richtig eingefärbt. Alle anderen Deckel sehen gut aus.




Es gibt allerdings noch eine weitere Ausnahme. Hier wieder ein Deckel, der nicht richtig eingefärbt ist. Diesmal allerdings nicht am Eingang der Höhle.





Wenn man sich die Datentabelle anschaut, kann man erkennen, woran das liegt.




Zwischen Punkt 16 und 16.4 hatte ich beim Erstellen des 3D-Modells einen Zwischenschritt 16f eingebaut, der eine Länge von 0 hat.
Das ist nötig, damit sich der Seitengang lückenlos an den Hauptgang anbindet. Außerdem kann man mit diesem Trick dem Anfang des Volumen-Teilstückes LRUD Werte geben. Das ist wichtig, weil sonst die Werte von der nächsten Station an beiden Enden verwendet werden.
