This is for Sylvain Leseur ( and those interested in this plugin, of
course):

I have a few comments on the first version of the plugin. It does not (yet)
reproduce exactly the povray code I think.

1) watch out that in Moray Y and Z axes are changed (right/left-handedness)

2) I would like to see the following sequence:

Pattern 1 [box]
   Scale <x,y,z>
   Rotate <x,y,z>
   Turbulence <x,y,z>
   Octaves n
   Omega n
   Lambda n
   Extra Transform <x,y,z>   == what you call Denting

Pattern 2 [box]
   Scale <x,y,z>
   Rotate <x,y,z>
   Turbulence <x,y,z>
   Octaves n
   Omega n
   Lambda n
   Extra Transform <x,y,z>   == what you call Checkering

Pattern 3 [box] etc....


3) Some way to indicate the relation between the different patterns (+ - *)

I test with my example 13 in the povray version of lanscape generator as it
is a clear broken-up landscape. I have not been able to reproduce this in
the plugin. But with the above changes, perhaps it will?  :-)
See also the isosurface plugin for Moray. It has not the HF capability, but
it does exactly what the povray script does.

Otherwise, a good start Sylvain!

Thomas

I add
scale <1,1,-1>
rotate <-90,0,0>
on Iso and HF
I think it's ok !???

Sorry Thomas I don't understand. Can you give me an exemple.

What do you wish exactly ?

Sorry many modifications. And i don't know how to do a compatibility We
the previous .lua. I have not finished with it of course. The code is...
Heu!
sometime strange. I need more time.
No more "editbox" for turbulences, transfos etc. Now "textedit". It's
smaller in
the Moray interface.
We can choice "Prédef" or "My Choice" functions with 2 buttons. There are
"Add
Other Functions" (some functions in thomas's LandscapeGenerator.pov), that
we
can add to   "Predef" or "My choice". Sometime it's strange, curious.....
I work on to get something good.
No comparaisons with S.Shonfiled's Isosurface (except the 3 letters
I.S.O)...
It's only to build Land, and it's more simple.Very very very simple.
Attached: landscapeori1.mdl to have a start, like with
LandscapeGenerator.pov,
(where we can find all the predefs), but with Moray.
Of course comments hardly welcome, for me this plugin is a "performance"!
There is
no Philippes Gibone who help me now...
Funny ideas welcome too. I wish it serious but funny too.
I try also to build a realistic wireframe with the help of function.lua
.....
I can't make head of it... But i'll find. (Maybe in 3 or 4 centuries.)

Bye
Friendly
Sylvain

Yes, that should work, I think...

Ok. I sent you an e-mail in french. Hope that it is more clear than my rapid
sketching... ;-)
