Head of git? The vtk version detection seems to get vtk5 and use those
libs. Forcing the 6 libs makes a working build.

[Therion] Therion and vtk7.1

[Philip Balister via Therion]

Anyone build therion with vtk7.1 on Fedora? It feels like some vtk
libraries have new names.

After a quick look, I do not recognize what license family it is.

My beef last time I tried building was it needed bleeding edge Qt stuff
that I couldn't find Fedora packages for.

While I understand your concerns, I'd rather the therion devs focus on
devleoping therion and not have to manage the infrastructure also. That
said, there is nothing stopping you from maintaining a free software
based mirror :)

This is a neat idea. It would be really helpful for walking over caves
and trying to match surface features with known passages. We are pretty
good at doing this hunched over our screens, but there is nothing like
seeing the actual ground when you are looking for new entrances.

Damn, you were the first person I thought of when I saw this.

[Therion] Therion + Subversion

I have had very good luck with therion + survex with subversion.

I also know of a project using compass with subversion.

[Therion] Symbolic links.

[Philip Balister]

So the problem is that when you use the the finder thingy, the absolute 
path is inserted? But you can successfully enter relative paths and 
paths via sym links by hand? Of course entering this by hand is painful 
I suspect 

I have a subversion repo I keep saurvey data in and the other Philip is 
workin on a map in this repo. So if he enters absolute paths into the 
therion map, I cannot check out his work and compile it on my machine 
without changing the paths.

Hopefully this is a very clear statement of the problem.

[Therion] Scaling issues with .3d files

Hmm, you are correct. I need to check whcih svx file Philip is working 
with. The range in meters is confusing me. Guess I need to look closely

[Therion] Scaling issues with .3d files

[Philip Balister]

Olly,

Just for your info the 3d file Philip Schuchardt is working with has the 
coordinate system for the cave set up so the station coordinates are 
also the UTM coordinates. This makes overlays easy with geo-referenced 
surface maps. This would explain why the x,y numbers are large.

Therion and survex

[Philip Balister]

Today I sat down and beat my head against the wall long enough to get
useful work from Therion. So far so good!

I'm wondering when Therion will be able to read LRUD from survex :) I'd
like to try out some of the 3d models.
