Isocontour and molecular visualization

In Chapter 1, Visualization as a Tool to Understand Data, we introduced the concept of scalar field, which is just a mathematical term used to describe the position-based values of a scalar quantity. Let's recap the example given in Chapter 1, Visualization as a Tool to Understand Data. Pressure, temperature, potential, and other physical values are often associated with coordinates to quantify the spatial variation of the physical parameter. To measure the temperature of a big space, instead of taking a single reading at a certain position, it makes better sense to measure the temperature at different locations and present them in a sorted manner.

A discrete scalar field is a set of such coordinates—scalar ...
