Principles of computer graphics Final project assignment – Michele Segata

The project

Develop an application to

•  Draw and manage different type of curves (control points dragging, use of composite curves, etc…)

•  Put an image as background to see which curve is best suited

•  Use a file as a source of points and display the curves using those points

Tools used

"   Only OpenGL and the graphic library developed for first assignment
