#!N #!Riterseq Iteration using the Sequencer #!N #!EC #!N #!N Caching
of intermediate results is particularly useful in conjunction with the Data
Explorer Sequencer module. The Sequencer provides Data Explorer with a very
simple and flexible animation capability. The sequencer outputs a frame count,
which is updated with each new execution. The user controls the
behavior using a VCR-like interactor (see #!Lsequen,dxall295 h Using the Sequencer #!EL ). #!N #!N The
first time the Sequencer is "played," it causes the network to
be executed with each value for the Sequencer output. Each execution,
which may be time consuming, will result in a new image
being generated. These images are simply the result of a rendering
module and will be retained in the cache. When the Sequencer
is "replayed," the inputs to the network are the same as
they were for one of the frames in the first set
of executions. Thus, the result of the execution (an image) will
be immediately available from the cache. Hence, Data Explorer provides an
automatic mechanism to create real-time animations even when the computation of
each frame is slower than real-time. #!N #!N The value produced
by the Sequencer can be used in a number of ways.
The Sequencer may be used to iterate through a time-dependent data
set, causing the visualization to operate on each time step in
turn, resulting in an animation showing how the data vary with
time. As another example, the Sequencer could be used to drive
the isovalue input to the Isosurface module. #!N #!N #!N #!F-adobe-times-medium-i-normal--18*
