vis_lic.pro
includes main-level programExample program demonstrating the use of VIS_LIC. Run the main-level example program with:
IDL> .run vis_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 VIS_LIC output:
The third image uses a color table to display the magnitude over the VIS_LIC output:
The second set of images are done with a smoothed instead of a random texture:
top vis_lic
vis_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
