I've been doing these on-screen graphics for a web channel that covers space
launches. We show a couple of different countdown clocks, as well as a block of
ascent parameters.
But for the last nine minutes of a shuttle launch, there's not much to show. I
have a couple dozen events that occur at various times during the count. I want
to display each one as it occurs. An event is just a text string describing the
event ("APU Start," "Steering Test," etc.).
My custom patch can either output each string on a output port, or output an
array of structures that has the string and the associated time. The former is
easier for me.
How can I crossfade from the last event string to the next, especially when
they come in rapid succession (perhaps more quickly than the crossfade
duration)?
I was doing a similar cross fade between a set of images, and it was a real
pain to build the structure for it.
Thanks for any suggestions,
Rick
