[vtkusers] help for rendering a 3D uniformly structured grid

[ehsan saei]

Dear all,

I'm very new in vtk. I want to visualize some 3D structures. let's say my
data is a 3D matrix (x,y,z) each element of this matrix is a float number
showing refractive index of my object. So for example element (i,j,k) shows
refractive index of my object at position (i*dx,j*dx,k*dx) in space. I
wanted to know how can I visualize using VTK?

Thanks in advance,
happy new year,
Ehsan
