Detailed Description

Reads seismic data into buffers providing a Moving Virtual Subcube of seismic data.

Note that the provider may skip incomplete parts.

The get() method returns a pointer to the trace, where you specify the inline and crossline number relative to the center. This is irrespective the steps in the cube's numbers. Therefore, the actual inline number of get(1,0) may be 10 higher than get(0,0) .

The advance() method moves the reader one step further along the seismic storage. The return value will tell you whether there is a new position available to work on, or that more traces need to be read first.

You can specify two stepouts: required and desired. The required stepout traces will always be available when the return of advance() is DataOK. If "Buffering" is returned, then the provider is still gathering more traces.
