Subject:	Progress Report on ACTI project:
			Advanced Flux Visualization ....
Date:		5 June 1995


Progress: Technical

	Met with partners in Houston during the last week of
	May.  We performed further evaluation on prototypes.

	Much effort has been focused upon data reduction techniques.
	The partners gave positive feedback on a "depth averaging"
	technique.  In this method of data reduction, "similar"
	simulation layers are "averaged" into a single flux value,
	then visualized.

	Demonstrated a prototype for a "virtual well."  The virtual
	well is used as a "seed point" or "rake" at which streamline
	computation/particle tracking commences.  The virtual well
	is placed into the flux and one is given immediate feedback
	about flux direction and magnitude at that point.  We discussed
	various aspects of the virtual well, such as problematic
	boundary conditions, and so forth.

	We are convering on a user-interface concept for flux visualization
	which combines visualization of abstract (ie, derived) data and
	raw data.  We feel that being able to simultaneously view raw
	and processed data is important.

Progress: Administrative

	I met with an attorney at Western Atlas, one Elizabeth
	Layman, Esq. to dicuss LBL's changes to the Western Atlas
	non-disclosure/code licensing agreement.  They agree to
	the changes that LBL has proposed, and are eager to use
	a "Data Exchange Agreement" rather than a CRADA.

	At this point, I'm waiting on the results of a Livermore-
	drafted "memorandum of understanding" to be completed, at which
	point this document will be tuned to this project.


Plans for Next Month
	
	Awaiting arrival of proprietary, large-scale data from BP.

	Construct prototype of streamlines/particle tracking.  (We were
	using the AVS module, but need source code to try additional
	ideas).
	
	Obtain source code for Western's 3DView, install on one of
	our machines.


Problem Areas

	None.
