I implemented the D2Q9 and the D3Q19 LBM in C/C++ language and I am using OpenGL to visualize the macroscopic fields. But I am interested in a more realistic visualization.
I have looked at Paraview, quickly. But I would like to implement something more realistic. I was thinking about Povray, but I have no experience with it.
Some time ago I read something about LBM Lighting. Has someone implemented it? Or do someone know more about it?

hello dear sicilia,
Right now i am also working on fluid visualization and simulation research area i understand about your thought which you are looking now but it will be more easy to help you if you will be more specific way because their certain techniques available which apply on visualization.
Thank you Shrish!
Let´s think only about the 2D model. I already have the visualization of the velocity field via draw of the vectors at each cell of the grid. In a same way, I visualize the density field via draw of colored points at each cell, where the color varies according to the range of the density. All of this give me a good representation of the flow. But I would like to think now as a real fluid. Simulate this 2D environment as the surface of a river, for example. I could think the 2D domain as a polygon, give it a color and work with transparency over it? Or maybe use the field of density to elevate the mesh according to the amount of mass?
Hello Sicilia,
I am working on CFD visualization as well. I think according to your description, Techplot will help you alot.
Hello Yousef. The Techplot that you've said is this one:
http://www.tecplot.com/
Yeas, tecplot have so many options to plot data , you can plot superimposed graphs, combine them in different ways. Also, it had different other tools of manipulating data...
Thank you all! I will learn about tecplot and soon I will let you know about my evolution!
I think Sicilia's talking about rendering the output data to make it look like realistic fluids. I don't think any of the mentioned software here does what she wants. Blender comes to mind as an option.
