Using Child Products to Adjust Price for Width and Height

[controlledfate]

Issue:
I am working on a site that offers a type of cover. The are 3 main product categories for the cover, which are basically different shapes: rounded, semi-circular and rectangular. Each cover is custom made and the sizes vary in width and projection. Since there are different sizes; there are many different permutations of products. For example a cover can be one of 3 shapes and range in width from around 20" up to 120" and a projection ranging from 2" to 100".

Question:
What's the best way to setup the products? Is it best to setup a single product for each shape, and then create child products (variants) for the different widths and projections? Similar to this site: http://www.selectblinds.com/cellularshades/38doublecell-lightfilter-cellular-shades.html <--- notice how you can adjust the width and height and the price adjust? Is that same functionality possible?

Is it not possible to recreate this same functionality in VirtueMart: http://www.selectblinds.com/cellularshades/38doublecell-lightfilter-cellular-shades.html

It's just a single product that you can adjust the width and height on and it will adjust the price accordingly.

I think this http://extensions.virtuemart.net/products/custom-size-detail should help you. I am not sure what you need, maybe not out of the box.

Do you know if they have a demo available? Couldn't locate anything on their site.
