[Radiance-general] rtrace-command

[Giulio Antonutto]

I think you are referring to rholo and the interactive visualizer.
In this case what you should do to see something is:
 
- 1 - 
create a rif file like:   file.rif
OCTREE= name_of_the_octree
view= view_name -vf view_file.vf
render= -av 0 0 0 -ab 1
 
- 2 - 
create a hif file like:   file.hif
RIF= file.rif
section= xo yo zo    Xx Xy Xz     Yx Yy Yz      Zx Zy Zz
 
where section is a box containing your scene (read manual for better
explanation), o is origin and X,Y,Z are the end of box's x,y,z axis.
example for the unit cube is:    0 0 0    1 0 0  0 1 0    0 0 1
 
- 3 - 
run rholo (*** pay attention here before typing) :
rholo -n 1 -f -o x11 file.hdk file.hif
 
where: 
-n 1 is the number of processors
-f  (***here!) means that the solution can be overwritten, the file.hdk
(!!!)
-o x11 means that the x11 display driver will be used (works on macX)
-o ogl (works on macX)
-o glx (do not works on macX)
 
of course the manual will explain better.... this is just a starting point
;-)
cheers,
giulio

Hi!

In the paper 'The Holodeck Interactive Ray Cache' the authors describe
amongs other things how the command rtrace is working. As far as I
understood, it is possible to interact with the virtual environment using a
mouse while running this command. Unfortunately I haven't managed yet to see
anything while running rtrace even for 2 hours. The octree-file I am using
is not that huge (5,2 MB), so I thing I am not using the right options of
rtrace (or I misunderstood the whole thing completely). Which options I am
supposed to use to run the program interactively? What would be an example
command line?

Thanks!
