What are ways to draw animations in C++? GDI+? OpenGL? Would you recommend a class pattern in particular to get the drawing and redrawing done?
Do you know of any open source project where animations are made so I can take a peek at the code?
Where would you start if you wanted to code geometrical animations? Do you know of any good libraries? Post links to tutorials and any other interesting information…
QT QGraphicsScene
It was specifically designed to make writing 2D games easy and effortless, with great support for animation.
QT is a very mature cross platform toolkit which also have an open source flavor.
