+[jGL](https://www.cmlab.csie.ntu.edu.tw/~robin/jGL/) was created by Robin Bing-Yu Chen in 1996 and has been maintained up to 2006. 
 It is a pure java implementation of OpenGL 1, hence performing 3d rendering with CPU instead of GPU. 
 Some papers about jGL published by Robin have been added to the `doc/papers` folder which clarify all his work.
-It comes with [lot of OpenGL Red Book examples](http://www.cmlab.csie.ntu.edu.tw/~robin/jGL/Example-app/index.html) proving how well
+It comes with [lot of OpenGL Red Book examples](https://www.cmlab.csie.ntu.edu.tw/~robin/jGL/Example-app/index.html) proving how well
 this OpenGL implementation works. The examples are released as [AWT applications](https://github.com/jzy3d/jGL/tree/master/src/main/java/examples/apps)
 and [Applets](https://github.com/jzy3d/jGL/tree/master/src/main/java/examples/applets).
