Searching for connect-the-dots data

[Evgeny.Makarov]

I am creating an exercise about splines, for which I need a set of about 10 to 200 points that form a picture when they are connected. Something like the following (from the book "Mathematical Elements for Computer Graphics" by Rogers and Adams).

I need a file with coordinates and the order in which the points should be connected. Is there such data in the public domain?

Thank you for your interest in splines and creating exercises related to them. There are various options for obtaining a set of points that form a picture when connected.

One option is to use existing datasets that are freely available in the public domain. For example, the National Institute of Standards and Technology (NIST) has a database of handwritten digit images that could potentially be used for your exercise. These images are made up of a set of points that form a digit when connected. You can find more information about this dataset here: https://www.nist.gov/srd/nist-special-database-19.

Another option is to generate your own set of points using mathematical functions or algorithms. This would allow you to have more control over the types of shapes and images that can be created. There are also various software tools and libraries available that can assist with generating these points, such as MATLAB or Python's matplotlib library.

I hope this information helps you in creating your exercise on splines. Best of luck with your project!
