Wow! Dipin! You blog has helped me a lot!Keep up the good work! Could you please upload a simple C++ program demonstrating 2d transformations: scaling, translation and rotation.? Thanks!

getch();
}
we need explanation for programs
it's a nice program please do more programs
please uplod a c program to show the rocket populsion and also upload a c program to show ripples in a pond
