Something was still missing: a fringe of foam along the coast line.

To my knowledge, only Zeger Knaepen and Jaime Vives Piqueres have added 
this feature to their landscape scenes, both back in 2004 so I do not 
know who was first.

- I studied both their - admittedly - very complex /isosurface/ 
landscapes and extracted the relevant codes for my own designs.

- I changed the code for height_field use as I generally find 
isosurfaces too slow for regular use.

- I 'improved' the work flow somewhat and 'improved' the foam texture 
more in particular.

- I put the code inside a demo scene for better accessibility of the 
feature, so that more people will be tempted to use it in future.

The demo scene, together with an example height_field map, is made 
available to all users in p.b.s-f.

By all means, feel free to change and improve upon the code :-)

Jaime was first :)

I used height_fields, no isosurfaces

Thanks! Good to know. ;-)

Both, I would say. In the scene from you I studied, there was a 
isosurface/height_field switch, based on a Shape_Quality parameter.

I also modeled some foam in a scene in 2008, though as I recall, it was 
a total hack:

The scene file is attached in one of the follow-ups.

I dimly remember that scene indeed. Thanks for the reminder. I shall not 
be able to refrain from having a peek at the source of course ;-)
