Hi Carlos,
There are a couple ways to do this in SCIRun. If you have a matrix or array
of numbers you can read in the matrix as an ascii matrix, or you can use the
matlab binary format. The SCIRun binary format is similar, but the other two
formats are more common. Once you read in the matrix you can convert it to a
2D image mesh using ConvertMatrixToField. You can also make a 3D grid using
CreatLatVol, then use SetFieldData to map the matrix values onto the grid.
Perhaps the best way to make a 3D grid of data is to use the nrrd file
format. Creating a nrrd is quite simple and it can be used to better control
the geometric information of the grid, such as spacing, size, and origin.
This file format can be read in to SCIRun as a LatVol using the ReadField
module and used in many ways. There are also many module designed
specifically for use with nrrd file formats in SCIRun. Please refer to the
http://teem.sourceforge.net/nrrd for more info on the nrrd format.
cheers,
Jess

I will really appreciate any help with the formats in this case.
