A simple library that helps you find points on a given line, if you know ONE of the following :
- The slope of the line and a point on the same line
- Two points on the line
It uses vector algebra and therefore is much intuitive to use. Look in the .h file for the entire API.
I used it while building the "throw away" photo animation for the Tempt app (https://www.tempt.com/). Code is released under the MIT license so feel free to use it the way you want!
