Default Parallelogram to Rectangular !?
Posts: n/a
I want to analyze the temperature distribution in a parallelogram plane. I have to create a rectangular shaped element which can go on by deviding them to squared elements.

would you please help me to convert this parallelogram to rectangular form ?!

I am using C++ to code this problem.but I don't know what algorithm should I use ?

I initially know that some mapping may be useful.but I couldn't derive a good mapping.

Best Regards

Look for bilinear transformation. Simple, and will do the trick (if I understand what you wish to do).
