[Paraview] please help do constuct 3d surface chart from csv file
Hi I want to use Paraview to construct a 3d surface chart from data that I have in a csv file. The data does not need any further manipulation. The file consists of 3 columns representing the x,y,z values of the points that I want to plot I have been able to open the file in Paraview - and applied the "table to points" filter. I can see the data in the spreadsheet view but do not know how to create a 3d view. When I split the window and click the 3d view option nothing is displayed.

Once you split and create the 3D view, click on the eyeball next to the "Table To Points" filter to turn visibility of the data generated by that filter in the 3D view to ON.

After that, you'll probably need delaunay 2d. -berk On Sat, Apr 17, 2010 at 3:56 AM, Utkarsh Ayachit wrote: > Once you split and create the 3D view, click on the eyeball next to > the "Table To Points" filter to turn visibility of the data generated > by that filter in the 3D view to ON. > > Utkarsh > > On Fri, Apr 16, 2010 at 10:27 AM, Chris Botha wrote: >> Hi >> >> I want to use Paraview to construct a 3d surface chart from data that >> I have in a csv file. >> >> The data does not need any further manipulation.

If the issue is indeed scale, then you can apply the Transform filter to scale the points.

Re: [Paraview] please help do constuct 3d surface chart from csv file
Utkarsh I am a new user to Paraview - and therefore do not know what to do when you say to apply the transform filter. I therefore searched the web for more information on how to apply the transform filter in Paraview. The best I could find was here : http://www.paraview.org/pipermail/paraview/2009-March/011560.html - I was able to use that answer to apply the scale that I need. I have also applied the Delaunay filter - and now have a 3d surface chart that I wanted! What do I need to do to see the coordinates of the cursor as I move it over the surface chart? I need to see the values of the local maximum.

Re: [Paraview] please help do constuct 3d surface chart from csv file
Hey Chris, Yes, you are on the right track with that mailing list entry. If you want to actually transform the values of the points, just go to Filters->Transform and then enter a factor between 0 and 1 in the appropriate Scale box (e.g. 0.2 in the third Scale column will multiply the Z values by 0.2). If you want to keep the original data values, but just scale the display, then go to the Display tab in the Object Inspector and all the way down at the bottom is a Transformation section where you can do the same sort of Scale entry. ParaView doesn't support hovering labels right now, but you can tell it to label selected points. Use one of the point selection tools to select some points on your grid. Then, go to View->Selection Inspector. At the bottom of that panel there is a Display Style section. If you hit the Point Label tab and check the Visible box you'll see PointID and other attributes in the Label Mode combo-box. If your point coordinates are not there, then you can apply the Calculator filter to your data: Attribute Mode: Point Data, Result Array Name: Coordinates (or something like that), Equation (next box down): coords (which you can get by pulling down on the Vectors button on the lower right. After you hit apply the coordinates of your points will be an explicit vector attribute of your point data, and this new vector should show up in the Label Mode combo box for Point Label.

Re: [Paraview] please help do constuct 3d surface chart from csv file
Eric Please know that I really appreciate the time you took to answer my query. I have done what you have suggested - and it brought me closer to what I want. Unfortunately it still does not do exactly what I want. I am at the point of accepting that Paraview is not what I need because: 1) When I transform the data so that the scales of the surface chart appears in proportion the actual data is transformed - I want to adjust the scales of the axis only - not the data because when I select the data I then have to divide the result again by the scale factor to know whet the actual values are. 2) It seem the Delaunay 2d filter seems to decrease the resolution of my data by drawing triangles only between major points. The ideal for me would be to not have any data manipulation at all - Paraview seems to be too powerful. 3) Learning how to do things is not easy - I would prefer a chat board / bulletin board over an email list - to see if other people has tried the same as what I am trying. There is nothing new under the sun. Regards Chris On Wed, Apr 21, 2010 at 3:06 PM, Eric E. Monson wrote: > Hey Chris, > > Yes, you are on the right track with that mailing list entry.

Re: [Paraview] please help do constuct 3d surface chart from csv file
Hey Chris, 1.) That is the point of the transformation which is in the Display tab -- it doesn't actually transform the data, only the display (the Transform Filter actually changes the data). So, with that Display transform the visual representation looks different but the data values are still the original. 2.) That seems strange. I thought it should use all points, but I'm definitely not an expert on Delaunay2D. How does it seem to determine "major points"? 3.) Sorry it's not working out for you. ParaView is definitely not always the most intuitive tool for beginners, but feel free to pass things by us in the future if you want to try again.
