<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi Joao,<br><br>Oh, perhaps this surface has a point data attribute array, like point ids or something? Can you open the vtp file in ParaView and see if it has an attribute array? If so, KiwiViewer will color the points using the attribute array. There is no way to disable that and use solid coloring, and no way to use opacity. If you delete the attribute array, then solid coloring and opacity should work. You could do this in your pipeline, if you're using a c++ vtk pipeline, like:<br>
<br>// get the poly data at the end of the pipeline<br>vtkPolyData* myData = contourFilter->GetOutput();<br><br>// remove all point data arrays<br>while (myData->GetPointData()->GetNumberOfArrays())<br> myData->GetPointData()->RemoveArray(0);<br>
<br><br>Regarding scene description files, KiwiViewer doesn't actually use any .kiwi files for the builtin example scenes. Most of the builtin datasets are just regular surfaces. The textured earth, brain atlas, and can animation are special purpose demos, and can't be described using the simple .kiwi file format.<span class="HOEnZb"><font color="#888888"><br>

Hi Pat,<div><br></div><div>Good to hear from you. I tried what you gave me and still the 3D model is completely red (tried opacity of 0.1). I'm using KiwiViewer from Android app store on a Galaxy S3. Eventually I will try to compile my own version. Do you have any more ideas for the opacity to work? Also, are those the only settings we can program without compiling a copy? The 'model-tapping to disappear function' I told you about can be simply coded in a .kiwi metafile as well?</div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi,<br><br>Sorry I did not notice your emails earlier! Regarding the transparency bug, could you try reformating your .kiwi metafile so it lists the volume first, then the surface, and add commas for each empty column, like this:<br>
<br>filename,r,g,b,a<br><div>37fr15.mha,,,,</div><div>LV_surface.vtp,1.0,0.0,0.0,0.5<br><br>Does that work any better? I've done a metafile just like this before with transparency on the surface and it worked correctly for me, but I can try again. Are you using KiwiViewer from the Android app store, or did you compile your own copy for Android or iOS?<br>
<br>For the brain atlas, I hope that in future releases the demo can be easily configurable for new models. Right now you could edit the models.txt file and replace the filenames, colors, and labels with your own, but the demo does require the skin and skull models to be present, and the initial position & scale of the clipping plane is hard coded.<br>
