Detailed Description

flow: a vector-valued function as a flow field

This class represents a vector-valued function of x, y and t as a flow field using streamlines. It uses fourth-order Runge-Kutta integration to determine the next points in the line, and along the line linearly increases the alpha value. This is contrary to the ink smearing analogy, and more the comet tail analogy (in ink smearing the tail points forward, and in the comet analogy the tail points backwards).

Constructor.

Parameters:

func

- the vector-valued function to render

Member Function Documentation

void glot::flow::dl_gen

(

const screen &

scr

)

[virtual]

Display-list generator.

Parameters:

scr

- the screen specs of the plot

This function generates the geometry that the geometry shader expects (a set of seed points). They are uniformly spaced on a grid.

Implements glot::primitive.
