A friend sent me some .fits files he’s captured with his telescope. However when I try to load them into TD it just crashes and tells me to update my drivers (which i have).
Just to test this I downloaded some other .fits files online, and while these don’t crash TD they just give me 1 channel (R) of points and nothing else. I’ve tested them in a .fits viewer and the files are totally fine and look great.
Has anyone managed to get .fits to display in TD? I’ve searched around and other than the wiki saying its possible I’ve not seen a single example of anyone actually doing it. If anyone could point (cloud) me in the right direction of how to do this I’d be very grateful. Thanks!
I should mention I tried converting them to .EXR and that just gives me a file with a single point in it. Also i’m on a non commercial licence, duno if resolution cap would cause the issue?
the .fits i downloaded from the linked page are .zip archives with 4 .fits files included, each file for a color channel plus luminance - so each file is actually just single channel.
To work with them in TouchDesigner, you would load them with a MovieFileIn TOP each and then use a Reorder TOP to combine all of them into a single texture.
One thing I found is to watch out what their value range is. While some seem to be in a 0-1 range, a particular sample is in the range of 0 to 65535 range - so to actually see something, activate the TOP viewer, r-click into it and select “Normalized Split”. You can also change the value range with a Math TOP or Limit TOP.
To test the crashing behaviour we would have to get a test file from you that triggers the crash. If you can’t post it here, you can email us at support@derivative.ca and we’ll see if we can replicate.
