Ok, as I understand from the flashback page it is a device that plays back ilda show. You have to load these shows onto the the device before you can play them back.
The LD2000 can’t save full shows to disc, which you could then stream to the Flashback device.
Let me describe how the ld2000 node interacts with the qm2000 board.
The qm2000 has a framestore with a capacity of several thousand frames, depending on the amount of memory installed on the board. One frame can hold a path with up to 6000 points. Paths can also be described as vector graphics, that means for a line you only need to define start and endpoint, the board adds the inbetween points on output.
With the ld2000 node you can access all of these frames. You can write to these frames and play them back. You can set certrain parameters for playback globally and per frame, like output points-per-second (pps), anchor points etc.
In the easiest live application you need only one frame, which you set as output frame and thus play back all the time. You overwrite it’s content in each v4 frame, and the board keeps outuputting that frame in it’s own refresh rate, until new content is written to it by v4.
You can also write to more than one frame of the framestore, which allows for non-realtime rendering of shows, or cuts and edits between certain scenes, if you want to build a whole ‘show’ like a movie. Once you’ve written all your frames you can play them back at your desired speed.
Now there’s a special feature of the board, that it doesn’t loose it’s content when you close the application that you used to write to it’s memory.
This way, all the frames that you write with v4 appear in the software ‘lasershow designer’ that comes with the board. You can re-edit the frames you created with v4, or save them to disc as shows, show parts or resources. These should also be playable by the Flashback device. But right now, I don’t see a way to get the graphics into ilda format out of v4 other than the workaround through the memory of the qm2000 board.
If you don’t need live content creation, it could make sense to look into the specifications of ilda show files, maybe you can create them as files out of v4 in another way. As far as I know, these showfiles are binary, though. Maybe there’s a way to import svg or piont lists into some lasershow software …
this is a video of a test made with the ld-qm2000 setup a while ago.
