How to generate LineIntegralConvolutionPlot for non-square geometries?

Posted 5 months ago

From the documentation, it is clear that

LineIntegralConvolutionPlot[{Subscript[v, x],Subscript[v, y]},{x,Subscript[x, min],Subscript[x, max]},{y,Subscript[y, min],Subscript[y, max]}]

can be used to generate plots for square geometries with geometry specified by

{x,Subscript[x, min],Subscript[x, max]},{y,Subscript[y, min],Subscript[y, max]}

How can we generate the corresponding non-square plots, for example, specified by reg (Region function)? What I mean is, how to generate these plots if the geometry is non-rectangular?
Also, what does the "white noise" mentioned on the function page represent? What does it signify? Thanks in advance!

Hi Michael,

Thanks for your reply and examples. This is what I was exactly looking for. It worked and the attached image shows the LICP of the same.

Not sure if this is quite what you want, but you could alter either the vector field or the image argument raster values to be zero outside the region of interest.
