PreStack3d renderer

[Dan Dromereschi]

Hi Bill, Bob,

I checked in a first version of the 3d viewer renderer for the PreStack3d entity.

Bill, is there a way to retrieve the Z slice? I couldn't find a getTracesByZOffset() method or something similar in the PreStack3d API. In PostStack3d, there is a getSlice() method, so maybe something similar might be needed? Anyway, for now, the renderer doesn't display the z slice.
I also noticed there are a lot of similar methods in the PreStack3d and PostStack3d entity classes: getXlineStart, ...Delta, ...End, getInlineStart,.... getNumXlines(). I can see that the implementation is not similar in some of them, but maybe defining an interface with these methods that both of them implement would help? Anyway, just a thought. I created methods having the same signatures in the PostStack3dRenderer and PreStack3dRenderer, but if there would be an interface to define them, I could move them to the abstract Seismic3dRenderer and could remove some duplicated code.

Bob, do we need to have the "Attribute #2" (velocity overlay) functionality for the PreStack3d too?

Thanks,

Dan

Dan,

Just looked at the 3D prestack viewer. It looks really good, and
behaved just the way
I had expected with the offset slider. Sorry about the getSlice()
method. I just haven't gotten
around to putting that in yet. As far as the commonalities between the
PostStack3d and
the PreStack3d model, what I might do is create another abstract class
(SeismicDataset3d),
that extends SeismicDataset and contains all the common features. Then
both PostStack3d
and PreStack3d can inherit from that. We could then do the same for
PostStack2d and a
PreStack2d, when we get around to that.

Dan,

 

I am finally getting around to answering your question. Yes, eventually we will want an Attribute 2 overlay for the prestack.  Please keep in mind that some day we may want to handle up to 5 or so overlays, each with their own display type (ie. density, wiggle, etc).

 

Thanks,

Bob
