Jaymie commented on Joe's Feature Request, “OpenCV create contours from image/colour

OK, so this would be a node that inputs an image and outputs a list of contour lines. Opened for voting.

On a similar request potentially, there was also _1024 Image to structure plugin

Interesting. That's different enough to be a separate feature request, if you'd like to create one. Is it still possible to download that plugin somewhere?

I like it. Screensaver attached.

eseftel, thanks for reporting this problem. Are you on macOS 10.14.4? If so, this is probably the same bug as Live video crashes/failures in macOS 10.14.4.

Jaymie commented on Teo's Discussion, “Cannot include <iostream> with vuo-compile

Can you explain the process of compiling a node?

  • First, vuo-compile invokes Clang to convert the .c or .cc file to an LLVM module. It passes along the header search paths from the vuo-compile arguments and adds a few additional arguments.
  • Then, it alters the LLVM module, renaming global variables and functions so that they are unique to the node class. For example, nodeEvent would be renamed to example_stateless_vuoize__nodeEvent.
  • Finally, it saves the altered LLVM module to file.

Hmm, we tested the same thing (renamed to example.stateless.vuoize.cc and added #include <iostream>) and it worked OK.

Maybe you're missing the C++ standard headers. Do you have both Xcode and the Xcode Command Line Tools installed? One of those provides the headers, offhand I don't know which.

Or here is an alternative implementation in C.
