Re: [Paraview] Unexpected lines in Surface with Edges mode with PV 3.14
Hello. In addition to my previous mail, I discovered that this problem of unexpected lines in Surface with Edges mode with PV 3.14 concerns only the Linux version ! I am using the 64 bits version on Linux CentOS 5.7. The Surface with Edges view is correct with PV 3.14 Windows 32 bits on Vista Home Premium SP2 ! If it may help you, the problem on the Linux version does not come from the Tecplot file format: I have also problems with surfaces given in VTM format. I add the gzip of my Tecplot test file that contains the surface representation of a wake behind a wing. Best regards. Richard. Richard GRENON a écrit : Hello, all. I have found a strange behavior of PV 3.14 in Surface with Edges mode for some surfaces: when reading some Tecplot files that contained a structured mesh, I get some unexpected lines that don't exist in the file and that don't appear when I select the Wireframe mode.

But right now we have need to manually figure this out. You need to construct your pipeline and have pv Proxy Objects in place before you can apply VR interactor styles to them. So things like 'RenderView1.HeadPose' implies 'Proxy.Property'. The state file stores this information about what Proxies and properties are available so you could infer this info from the state file. An easier way to figure out the objects available is to use the Property Linking Tool in the GUI Tools-Manage Links-Add-Mode:PropertyLinks I am attaching a sample state file which may be useful. -Nikhil On Mon, Mar 12, 2012 at 2:42 AM, Christian Wohlschlager christian.wohlschla...@jku.at wrote: Dear Nikhil !

Re: [Paraview] [EXTERNAL] Paraview can't show grads origin data
OK. I see now. Clearly I'm not familiar with the GrADS software or its data formats. If someone else on the ParaView mailing list is familiar with GrADS it would be great if they speak up, but according to the mail archives GrADS has not yet been discussed. I suspect the problem is that ParaView simply does not know how to read the type of netCDF files written by GrADS. NetCDF is not a completely specified file format. Rather, it is a collection of arrays that are self describing. That is, the arrays and dimensions are named and can have properties, but to read them properly you really have to understand what these metadata mean. There are actually several readers in ParaView that use netCDF as the underlying technology, but only one that makes an attempt to generally read unknown conventions. It will assume that arrays are regular grids with up to three physical dimensions (x/y/z or lat/lon/z) and optionally a time dimension. Based on about 5 minutes looking at the GrADS web pages, I'm guessing that the netCDF file GrADS is outputting contains 5 dimensional arrays. In this case, the ParaView reader won't know what to do with 5 dimensions and will therefore issue an error if you try to read one. (You never actually said what went wrong, but perhaps that is it.) I'm sorry that probably none of this is helping. Ultimately, it sounds like a new reader would have to be created for ParaView. -Ken On 3/13/12 2:28 AM, wang w...@knmi.nl wrote: Thanks for your reply.

Xueli Moreland, Kenneth wrote: I don't know what you mean by a grad or what problem it is causing, so I'm going to make a total guess. I am guessing that you mean gradian (a unit equal to 9/10 of a degree). Furthermore, because I can't think of any other way such units would mess you up, I am guessing that you are trying to write spherical coordinates in terms of gradians, but ParaView is interpreting them either as degrees or as Cartesian coordinates. Assuming that this is the problem, it is caused by the fact that the default netCDF reader for ParaView honors the CF convention (http://cf-pcmdi.llnl.gov), and the CF convention specifies spherical coordinates in terms of degrees. To specify angles in any other units is to break the convention. Your best solution is to convert your gradians to degrees (it's OK to have floating-point degrees) and write a netCDF file that properly follows the CF convention. If I have completely missed the point of your question, you'll have to better explain what are grads and what problem you are having with them. -Ken On 3/12/12 10:13 AM, wangw...@knmi.nl wrote: Dear Paraview users, I have problem with data that origin of grads.

Re: [Paraview] [EXTERNAL] 2d selections
I see that if you make a second selection in the same 2d plot, the old points are unselected and the new points are selected. But if you try to select nothing, nothing changes. I would think that the current selection would be cleared out, so this sounds like a bug. I also notice that if I go to a different view and select a different object, the old selection in the 2d plot remains. I believe all the selections are supposed to be linked together, so this sounds like a different bug. -Ken From: Scott, W Alan wasc...@sandia.govmailto:wasc...@sandia.gov Date: Tue, 13 Mar 2012 23:50:02 + To: paraview@paraview.orgmailto:paraview@paraview.org paraview@paraview.orgmailto:paraview@paraview.org Subject: [EXTERNAL] [Paraview] 2d selections I have selected some of the points in a 2d view (plot over line), and have no idea how to unselect these points.
