#fractal landscape
11 messages in this thread
does anyone know if there is some sort of a good fractal landscape
generator for the pc out there? i'd like to render some flythroughs.
chaos offers a dxf-out, but its output is very poor. i've seen some stuff
for the amiga- beautyful.
so, if anyone has an idea please leave me a note.
my current configuration: 486/33, 4167 weitek, 30megs ram, vista and spea
framebuffer. acad11 plus ame, studio3d, dxf3dsw, lumena, windows-stuff
,…

There is a fractal generator program in the Comart forum lib 14 called
FRACINT, it is a freeware program. I personally have just started using it
to generate landscapes, however, a freind of mine swear by it. It will
output .tga and .gif files for definite. Hope the info is of some
assistance.

I'm currently working with flying over fractal landscapes, myself. I use
Fractint from over in the COMART forum. Here's what to do once you get it:
Create a plasma fractal, the higher resolution, the better. Then use
GIF2DXF (available somewhere in the libs here) to turn the plasma gif into
a dxf file. The dxf file is directly loadable into 3d Studio, except
you'll have to apply smoothing (if you want it) and flip the normals. I
recommend meshes of 100×100 or greater for realistic looking landscapes. In
my opinion, fractint is a great program for making texture and bump maps as
well (not to mention opacity and reflection too <g>). In fact, you may
want to map a plasma bump map onto your landscape object to add even more
detail.

Arron,
I do the same thing for fractal landscapes, but I always get a couple of
faces here and there with their normals flipped. It's a pain in the neck
to try and figure our exactly which faces need to be flipped and do it.
Could my problem be that I don't use DXF3DS? Do you use it? Who do you
work for? I thought I was the only one smart enough to get paid to play
with such silly things in 3DS…

I don't use DXF3DS at all. Just GIFDXF the plasma gif and load the dxf
into 3d studio as a dxf file. Derive object names from entity, flip the
normals, apply smoothing and off you go. I've never had any problem with
one or two faces flipped over. You could always apply a two sided material
to fix that though, as I doubt you'd ever want to fly underneath your
landscapes.

Arron could you tell me where to find gif2dxf, i have looked hi and low and
have yet to find it Thanks, Rock
It's called GIFDXF.ZIP and it's in the Autodesk 3D Studio library.

thanks aron, I was looking in the wrong area rock
Norbert,
You can download the QuickSurf ADS demo program to use with your
Acad 11. The QuickSurf demo program has a terrain generator built-in. The
program can be downloaded from:

P.S. Might want to check out the landscape GIF's on the board as well.
Those Amiga fractal programs often save out true 3D data in several
different formats. If you've got an Amiga, you can use our "InterChange"
translation program to move from any Amiga 3D format to .DXF format. In the
next few weeks, I'll be working on an article on "science software" for
Compute magazine and I plan on talking about these 3D fractal programs, so
ask again later, and I may know more. If you like, I can upload a few
sample landscapes in 3DS format.
thanks, it would be nice to see some samples of the amiga landscapes in 3ds
or dxf format. if you're so kind an upload some.
according your interchange programm i'm seriously interessted.
thanks in advance, norbert
