Thanks Sebastien .. that was the problem :) It works fine now and I can switch the different datasets on/off.

The reason why only the last one is set correctly, it's because ParaView has a stack of active objects. And since the SetDisplayProperties requires a "proxy" and a "view", if you do not provide them, ParaView will use the last one created. So to solve what you are facing you have to call the following code: pv.SetDisplayProperties( { proxy: data1, view : view1, SelectMapper : 'GPU', Representation : 'Volume', LookupTable : lut1, ColorArrayName : 'ImageFile', ScalarOpacityFunction : f, } ); But the best way to go might be to define a method that do that function setDisplayProperties( data ) { pv.SetDisplayProperties( { proxy: data, view : view1, SelectMapper : 'GPU', Representation : 'Volume', LookupTable : lut1, ColorArrayName : 'ImageFile', ScalarOpacityFunction : f, } );} and then just call setDisplayProperties(data1);setDisplayProperties(data2); Seb On Wed, Apr 27, 2011 at 6:32 PM, Rajvikram Singh <[email protected]> wrote: Hi everyone .. Greetings ! I'm trying to create a web visualization page where biologists in our lab can see their multi-channel volume data. Each channel is a separate file and since there could be as many as 11-12 channels I want to give them the ability to switch the volumes on/off or even see two volumes in the same space. To test this I wrote the following Javascript code to load two volume files (.vtk) and then show only one. The problem is though I get no errors, I can only see the last file that's loaded (I've tried different combination of files). When I try to show the first file, all I see is a gray box instead of the data. It almost feels like the OpenDataFile() function is using the same object and overwrites it. I'm new to Javascript and would not be surprised if I'm doing something silly but any advice is sincerely appreciated. Javascript Code : // Set the web service base URL var serverUrl = "<%=request.getScheme()%>://<%=request.getServerName()%>:<%=request.getServerPort()%>/PWService"; // // Create a paraview proxy // var pv = new Paraview(serverUrl); pv.createSession("Test Visualization", "Ver 0.1", "default"); var view1 = pv.CreateIfNeededRenderView(); pv.Render(); // Load the data files in RAM var data1 = pv.OpenDataFile('test1.vtk'); var Representation1 = pv.Hide({proxy: data1}); var data2 = pv.OpenDataFile('test2.vtk'); var Representation2 = pv.Hide({proxy : data2}); // Init view parameters var lut1 = pv.GetLookupTableForArray({arrayname : "ImageFile", num_components : 1, HSVWrap : 0, NanColor : [0.0, 0.66666666666666663, 0.0], RGBPoints : [1.0, 0.0, 0.0, 0.0, 16564.27904630101, 1.0, 0.035950255588616767, 0.0, 19924.923666800998, 1.0, 0.035950255588616767, 0.0, 39728.909301543368, 0.0, 0.66666666666666663, 0.0, 65294.000000000007, 0.0, 0.0, 0.0], ColorSpace : 'HSV'}); var f = pv.CreatePiecewiseFunction( {Points:[0.0, 0.0, 2762.37, 0.0588235, 2882.47, 0, 6965.97, 0.235294, 15373.2, 0.323529, 25221.6, 0, 26662.9, 0, 36751.5, 0, 44318, 0.0, 52124.7, 0.323529, 63054, 0.294118, 65336, 0.294118] }); pv.SetDisplayProperties( { view : view1, SelectMapper : 'GPU', Representation : 'Volume', LookupTable : lut1, ColorArrayName : 'ImageFile', ScalarOpacityFunction : f, } ); // Show one dataset only pv.Show({proxy : data2}); Thanks in advance Raj _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview
