Scalar fields
What is a scalar field
 A mapping from every point in 3D to a scalar value
 Example: temperature in each point in a room
 Hard to visualize in 3D as points will cover each others
 Can be partly visualized by slicing
How to map a scalar field to a 3D body
 Define the 3D body as all points in 3D with a scalar value larger or less than a fixed limit
CAD design in 4D by scalar fields
An alternative design method based on working with 4dimensional bodies that are finally transforming down to 3D
Properties
 Fully organic design that is difficult (impossible?) to achieve by working directly in 3D
 More experience is needed to tell ...
