hello Opendtect community from a new joiner,

I am just having a play around with the sample F3 project that comes with the download, and trying to understand how horizons display between 2D and 3D.  I have displayed inline 300 in the 2D viewer, and done a rudimentary horizon patch ( Im not actually trying to follow anything!) and then expected the same patch to be displayed in the 3D viewer of the same line - see pic below.  But for some reason, in the 3D viewer it seems to be trying to snap to some big event or other, even though it was set to Manual no Snap when I manually picked it.  how can I get it to display the horizon exactly as it was picked?
many thanks, tony

Hi Tony,

Welcome to the OpendTect Community!
I've just followed the workflow you describe: manually drew a 'random horizon' on inline 300 in the 2D viewer, then viewed the same in the 3D scene.
The results for me were exactly as to be expected: 

2022-10-12 11_41_06-OpendTect Pro V6.6.9rc5 (Windows)  _ F3 Demo 2020  [free project] - [Scene 1].png

We did have certain issues with this in a previous version and I notice that you are using OpendTect 6.6.5....
I suggest that the first thing to try would be to update to the latest public version, v6.6.8, and try the same workflow again.

If you need references for download & installation, you can find them here in our Administrator's Manual.
Do also take a look at the System Requirements.

Please let me know how it goes.

Kind regards,
Mark

many thanks!  In the meantime, Ive just tried the same thing (same version) on another laptop and get a slightly different result - i wonder if some of it might be the graphics card, as i am getting different line thicknesses also.  Anyway I'll give that a shot.

thanks for your time.
Tony Brewster

Hello again.  I more or less followed my nose for the upgrade to 6.6.8, but for some reason it seems to only want to give me the Pro version - I get this when I click Select Free Project

there didnt seem to be any option to install the free version update. The first time I installed it 9 a while ago) I seem to remember being asked to specify which versioni i wanted.  perhaps the update is not available for the free version?

Any help appreciated.  I guess I could blitz everything ans re-download from scratch.

Tony

Hi Tony,

Graphics card types can have a huge influence on what you see in the viewers.
Please take a look at our System Requirements for your platform and see what the recommended types are.

You can also, for optimum results:


Kind regards,

Hi Tony,

Yes, it would be best to do a fresh install of 6.6.8 in this case.
Because you updated from a Pro version of 6.6.5, the installer remembers that and skips the choice between Free & Pro.

Aain, the relevant link from this page should help you.
Note: there's no requirement from OpendTect's perspective that it be installed into Program Files.

Good luck and get back to us if you need to.

Kind regards,
Mark
