 * CMake instead of autotools
 
-## Compiling on Linux Mint 
+## Additional changes (this project)
 
-Tested for Linux Mint 18.3, but should also work for other Ubuntu-type Linux distributions:
+* Windows/MSVC port - remove use of features unsupported by MSVC such as VLAs. 
+* Remove all output options other than SVG 
+* Embed required components from GNU Scientific Library
+* Remove all external dependencies
+* WIP add a driver program that can generate output from a specificatin given in a text file.
+* WIP add support aspherical surfaces as specified in patent literature.

-For creating the Makefiles via `cmake`, use:

-After successfully creating the Makefiles, perform `make`:

-As a result, you should find lots of examples in the `examples` sub directory which can be executed and the plots can be inspected by using, e.g., `inkscape`.

-#### Install pre-requisites
-
-```
-sudo yum install gsl-devel.x86_6
-sudo yum install gd-devel
-sudo yum install plplot-devel
-sudo yum install mesa-libGL
-sudo yum install freeglut-devel
-sudo yum install opencv
-sudo yum install opencv-devel
-```
-
-I had to disable DIME as I could not install the dependency.
-It also seems that removing the two render examples also removes dependency on OpenGL, GLUT, OpenCV and X11.
-
-I am using CMake 3.14 which I installed manually.
+# Building on Windows
 
+Similar to above except that `cmake` creates Visual Studio solution, so you can build using Visual Studio 2019.
