How can I make pov file?

[Namkyu Kim]

I installed VAMPIRE, and simulating the input file.

So, I get the output file.  But, I saw that VAMPIRE can make pov file for 3-D imaging.

How can I make that file and where can I find it?

To create a povray file, you need to specify the output of atomic coordinates in the input file using:

config:atoms 

This creates a number of snapshots (one for each CPU) of the atomic spin configurations. In the util folder of the source code distribution there is a file cfg2povray.cpp which you can compile using

g++ cfg2povray.cpp -o cfg2povray

Running this executable in the same folder as you run the code will generate a sequence of atoms-***.pov files. These can then be rendered using the povray ray tracer, e.g.:

povray -W800 -H600 +A0.3 atoms-000000.pov

Hi Namkyu,

I had the same question as you. Did you manage to generate the pov. files?

Thanks,

Hi Richard,

I generated the executable file named cfg2povray successfully, but I couldn't generate atoms-***.pov files by running that file as you said. I was wondering what the problem was. Could you explain the sentence that "Running this executable in the same folder as you run the code" in more details?

Thank you very much!

Best,

Chaoxin

Hi Chaoxin,

Depending on the version you are using, the povray files are produced using the util/vdc/vdc utility, after generating atomic configurations from the config:atoms keyword in the input file. To compile this utility you need to run “make vdc” in the vampire source code folder. You can then copy the file util/vdc/vdc to wherever run your simulations and type “./vdc” to process the data files into .pov files.

All the best,

Richard
