Synopsis

Mathematics and CAD Numerical Methods for CAD by Yvon Gardan

The use of computer-aided design (CAD) systems always involves the introduction of mathematical concepts. It is important, therefore, for any systems designer to have a good grasp of the mathematical bases used in CAD. The choice of mathematical models in a system also has an effect on the overall quality, although this effect may not always be visible to the final user. Depending on whether Bezier or B-spline functions are used for curves and surfaces, for example, the final user even if not a com- puter scientist will notice a difference. If, for example, one of the control points is modified by the user, in a Bezier-type representation, the curve or surface will tend to be modified overall, but in a B-spline representation, the curve or surface will tend to be modified close to the point, and there only. More possibly harmful, however, is the effect of the mathematical model which has a number of properties invisible and unknown to the final user. In every case a model must be chosen with, it is hoped, the most appropriate characteristics and limits for the task in hand.

We love Lovereading4kids because they put books in front of us we wouldn’t otherwise have read. They make us more adventurous readers!

Emily Jacques

I love Lovereading4kids because I get an opportunity to put my opinion forward and to try new books

Elosie Clarkson – age 11

I love Lovereading because I often never know what to read and this helps you find a good book. I have recommended this to many people.

Shannon-Louise Masters – age 15

It’s a community united by a passion for books and promoting the best there is in children’s literature.

Sam Bateman and family

I love ‘LoveReading 4 kids’ because they let you read and learn things you’d never dreamed of learning before.

Emily Horncastle – age 11

You give me age appropriate ideas of books I can read and buy for the children and find out what other children their age think of them too.

Katie Lonsdale

It has introduced my children to books we hadn’t come across before. Real children’s reviews gives a great insight into what others think to

Lorraine Woods

I am so pleased to have signed my kids up as they are reading a much wider range of books and even choosing books out of their comfort zone.
