Hello,

I am currently working an a project where it is necessary to modell and
render realistic looking caves and landscapes. It is sort of similiar
to the task of designing the graphics for the games Myst and Riven.
Can anyone help me, please ?
Thanx in advance

Thomas

Create a height field , turn it upside down, put the two halves together and
voila a cave!

Rocktools(currently, AFAIK, only for linux and SGI)

The first two utilities are free, but leveller is some $30-$40.
You may want to remember that the makers of myst and riven had a fairly
large budget, and professional tools.

Is this a challenge?

No, I was just making a note, and a bit of a caveat. If you want to produce
images similar in quality to the ones that they have, you probably should be
prepared for massive rendering times, vast use of disk space by meshes and
very high learning curves. One might also assume that you are something of a
beginner, as your question was directed at making landscapes as well as
caves, and most experienced raytracers have a least a passing familiarity
with heightfields that your message did not convey. If this assumption is
innaccurate, then I am sorry for what must appear to be a supercillious
attitude.

I neither want to make images similiar to the ones in Myst and Riven in
qualatiy nor want I make large models. And I also have a basic
understanding
of things like heightfields and how to use them. I just wondered how to 
modell them another way.

See my links page for HF modelling programs. They vary from freeware to
low cost shareware and offer many powerfull features.

But...
In an article I read on them recently regarding doing a movie, the one thing
mentioned was how they concentrate on "garage shop" kind of stuff, and avoid
the high-end super power user packages, hardware, etc.

Of course, their garage is probably _much_ nicer than mine, but nowhere neat
ILM.

Another method is to make a blob object and subtract it from a box or
hightfield or something to make a cave.

and then subtract further height fields from that difference to create rough
walls.
