Interactive Graphics

[ricardoangelico]

What is the better way for starting to work with interactive graphics? How can I do the graphics interact with the users?

My objective is construct a simple CAD program for using it in another program.

I want to construct lines, polygons, circles,...

Operations like divide, delete and others.

Can you help me? Please

Assuming you know OpenGL, you then need to determine what your target windowing system will be. If you want things to be portable you might look at wxWindows, www.wxwindows.org. (http://www.wxwindows.org.) It's a C++ GUI framework for Windows, Unix, Linux, and MacOS.

The program will be developed using C++ on Windows system.
