Hi Imene,

Did you download the tutorial files? They can be found here:

    http://www.jaloxa.eu/resources/radiance/documentation/docs/radfiles_tutorial.zip

I believe that this has what you need to work through the tutorial including views/nice.vf.

Just to add to Jack's and Thomas' replies to your question (I'm assuming you're using a UNIX version of Radiance). You're probably wondering now how this view file was created in the first place.

If you run
$ rvu scene.oct
the interactive Radiance scene viewer rvu is launched with your scene in it. BTW: If you are reading some VERY old documentation which is still out there on the Internet, the command would be 'rview', not 'rvu'. You can now use the command prompt at the bottom of the rvu window to move the camera around. A list of the most useful rvu commands is in the table on p18 of the Tutorial. Apart from 'aim', which is always handy, the commands I use most often are:

- when inside a room: 'rotate'
- when looking from the outside: 'pivot'

The tricky bit is always to get the view point right. If you are inside a room, a good starting point is to identify a good view point (think tripod and camera) by looking at your plan and elevations/sections which, of course, you have at least as scribble on a bit of paper.

For external views, a good start is to first run
$ objview scene.mat scene.rad etc

objview takes the material and scene files, adds a few light sources, compiles an octree, and then calls rvu. Now use 'pivot' (and the other rvu commands to move around the model. Once you have a good view, save it like this from the rvu prompt:
: view views/nice.vf
: q

You can now run rvu to look at the scene under your proper light sources, rather than the ones objview puts in:
$ rvu -vf views/nice.vf scene.oct

Or, you can run
$ rvu scene.oct
and
: last views/nice.vf

Hope this helps

Regards

Axel

Just to add to Axel's addition, I recently ported objview from csh to Ruby
so that Windows users can have access to this rather useful utility. I
also added in the old 'ltview' (luminaire viewer) functionality that I
wrote many years ago, which was simply a modified version of objview. It's
sitting on a far back burner and just needs some more testing. The hope is
it can be added to the Radiance source tree and built into the NREL
installers, but failing that we'll just offer it as a download on the
OpenStudio website when it's done. If anyone wants to beat on it, I can
send you a copy offline for now.
