Dear all,<br><br>I am newbie to Paraview and I want to ask you something. I am working with signals and I use gnuplot for plotting. Unfortunately it's slow for big signals. Our program is parallel so we can create files of many GBs. We do a tricky parallel plot, every cpu plots a part of the signal, otherwise we couldn't see the image from gnuplot (crash). So when I saw paraview I liked a lot but it isn't easy.<br>
<br>I must explain what I want to plot:<br>We use a techinque in order to cut the points that haven't energy. For example a specific signal with 12000 x 12000 mesh of points which is 8GB file it can go under of 1GB if we cut the useless points. So I give at the gnuplot only the points that I want to plot x,y,z and I use pm3d map because I want them in 2D not 3D for example see the image: <a href="http://www.markomanolis.com/files/plots/plot.jpg">http://www.markomanolis.com/files/plots/plot.jpg</a> <br>
I would like to ask. Is this unstructured grid? I show an easy signal it could be with more random points. I have tried unstructured grid for 2 columns only and there is no surface between the columns. I used triangle strip and it was ok but I don't know if I could see the details like here (here I don't cut any useless point, in first image see wave details in the center): <a href="http://www.markomanolis.com/files/plots/62_0_0.jpg">http://www.markomanolis.com/files/plots/62_0_0.jpg</a> , <a href="http://www.markomanolis.com/files/plots/resFinal.jpg">http://www.markomanolis.com/files/plots/resFinal.jpg</a> .<br>
Could I have these plots with paraview or it is good with more complicated plots?<br>I must write a script/ program to convert gnuplot file to paraview but I am not sure about the topology, I must declare the topolgy for every point, right? I am confused because I have a lot of constrains for example if a point is alone then the topology is vertex if there is another point then line etc... Is there any way to plot this grid with something like image data. I want to give something like structured grid but NOT to give all the points (I don't need them). The last two images I sent you are with all the points for education propose. I want to plot something like first image but witho more complicated topology <br>
<br>Thank you for your time,<br>George Markomanolis<br>
