mg_lic.pro

includes main-level program

Example program demonstrating the use of MG_LIC. Run the main-level example program with:

  IDL> .run mg_lic

The first image is the direct output of MG_LIC:

The next image introduces color by using HSV color coordinates with hue equal to red, saturation equal to the vector field magnitude, and value equal to MG_LIC output:

The third image uses a color table to display the magnitude over the MG_LIC output:

The second set of images are done with a smoothed instead of a random texture:

Routines

top mg_lic

mg_lic, u, v [, texture=bytarr(m, n)]

Compute the line integral convolution for a vector field.

Parameters

u in required type=fltarr(m, n)

x-coordinates of vector field

v in required type=fltarr(m, n)

y-coordinates of vector field

Keywords

texture in optional type=bytarr(m, n): random texture map; it is useful to use the same texture map for generating frames of a movie
