need advice on how to display graphics

[martymarty]

I am a beginner that has been attracted to 3D computer graphics after reading
YouTube lectures on computer graphics

1. I have learned matrices to Scale, Rotate, and Translate a 3D cube
Now I wish to view this 3D transformation on my computer screen as a series
of steps .

2. Then I wish to color that cube and move its position, DYNAMICALLY
and watch that transformation on the computer screen.

3. I am begiining to learn C++ and OPenGL in order to go deeper into
computer graphics.

QUESTION:
Please suggest low cost computer program that will enable me to
LEARN how to do (1), (2) above and will be compatiable with C++ and OPenGL.

If I have missed something here please set me straight. (I really DON'T
know, even if my question seems otherwise !)

Once again I must recommend the arc-synthesis tutorial.

Best OpenGL tutorial I've ever read. It will help you with everything you're asking about.
