[Developers] SeisSelData question

Mon Nov 10 11:00:33 CET 2008

Greetings to all dGB stuff!!!

I have idea to realize seismic section animation like in Petrel, Kingdom Suite, but I have lack of
understanding  how read subvolumes (sections) from uiSeisSel. I have attached screenshot of my
plugin's code, this is draft version and I'am in beginning stage. At first I want extract for example
first inline (see code) from entire cube using SeisTrcTranslator and SeisSelData classes and render it
in a 2DViewer.But I can't. All the same SeisTrcBuf contains all cube. If  set \
SeisSelData::all_ to false I can't read any trace.
Another problem with FlatView::Viewer::setPack function, it crashes even I use only 200 traces. 

This is a debug information from od_crash_analysis.txt:

Program received signal SIGSEGV, Segmentation fault.

Please can you revise my code (I am beginner in OpendTect) and point my mistakes.

Thanks in advance!
