Detailed Description

scalar_field: a scalar field to plot

This class takes a scalar-valued function of x, y and t and renders the resulting scalar field with a fragment shader. The shader expects the value of the function to be scaled between -1 and 1 and will clamp any value outside of that. (For instance, -10 gets mapped to the color for -1 and 1220 gets mapped to the value for 1).

Future versions will allow for a user-specified range, and ideally would also have a mode that automatically scales the values appropriately.
