[Paraview] Grouping a texturable and an untexturable object
Hi - I've got two objects -- vtp meshes actually. One has texture coordinates and the other doesn't. I'd like to group both objects and apply a common transform to them. Is there a way to do this in Paraview? I've tried placing both objects in a pvd file. Unfortunately, this pvd file cannot be textured. Is there a way around this problem?

Thanks Menno. However I'm trying to rotate the objects in the scene and
not the camera. I've got two objects side by side and I'd like to rotate
both of them while keeping the camera still.
Thanks.

[Paraview] Getting Python object reference to representation/proxy of each object loaded in Paraview.
Hi, I'd like to get the reference to representation or proxy (not sure which I need) to each object loaded in Paraview via Python.

[Paraview] CoProcessing/Client-Server Paraview
This email was originally sent as a reply to a thread http://markmail.org/message/t22jsckztvnoyafz?q=Paraview started by Alexander. For some reason no one responded to my comments. Nevertheless the important question Andy Bauer raised is if Paraview is used for tasks that do not require the VTK pipeline (paraphrasing). To this I can reply and emphatic yes. I use Paraview for visualization because the VTK format is the only graphics file format the supports points, line, and surfaces and as a ready-made viewer (Paraview). Therefore my programs (I'm doing geometry processing) save point, line and surface data as VTK files and no pipeline is required -- just a viewer. What would be nice would be a *simple* communication mechanism with which my program can instruct Paraview to just load processed data as soon as they become available. I'd like to know the difference between CoProcessing and the following feature that is currently being implemented: http://paraview.uservoice.com/forums/11350-general/suggestions/456005-writing-to-paraview-from-an-external-program?ref=title (an ETA on this feature would be nice) From a cursory glance and my experience with other 3d apps (namely AutoDesk Maya) I find the current CoProcessing(?) implementation a bit too complicated. AutoDesk Maya, a highend 3d animation program, has a commandPort feature that very simple to use. All it requires is a single command that creates a socket and binds a specified port number to it. Thereafter any external app can send commands to Maya in its primary scripting language (MEL) and I suspect now also python. For example, I've configured my toolchain/IDE (Visual Studio) to send Maya a command, via the commandPort channel, to unload plugins before attempting to rebuild them. After building the toolchain/IDE sends another command to Maya asking it to reload the plugin. Basically, any scripting command that Maya accepts can be sent by and external app via the commandPort. http://download.autodesk.com/us/maya/2011help/CommandsPython/commandPort.html Can communication between Paraview and external apps be made this simple? - Olumide ___ 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

Re: [Paraview] Creating Animations in Paraview, where's the Animation Inspector
Thanks. I've experimented with keyframes dialog. And you are right: the animation curve isn't nearly as nice as I'd expected. The standard solution to camera control in 3d software is to give the user access to the animation curves created by setting keyframes, so that the user than can set or correct the tangent/tension at the keyframes. Orbits are nice but they are very limited. Paths too are nice but they are extremely difficult to create define "by hand". I'd vote for animation curves. - Olumide ___ 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
Re: [Paraview] Creating Animations in Paraview, where's the Animation Inspector
I would like to create an animation in which the camera literally inspects various parts my model/scene. The sort of camera paths I need to specify are hard to manually describe as an animation curve (even very simple camera paths are hard to manually describe as animation curves). Is it possible to manually move the camera to various locations, and set a keyframe at each location as is the practice in 3d applications? This would be a _lot_ simpler than specifying animation curves by hand.

Re: [Paraview] Use existing texture map for 3D surface
HI Eric, What you see in the image http://tinyurl.com/y3sqtbt are the faces of the model in UV space. The image is therefore an explicit specification of texture coordinates on a per-face basis. That is to say, the representation allows texture coordinates to independently specified for each face. And as a result, seams appear in the UV space representation whenever a vertex has more than 1 texture coordinate e.g. a diffuerent texture coordinate for each face or group of faces. CGI artists refer to this process of creating this representation as UV-unwrapping. See: http://www.blender.org/development/release-logs/blender-234/uv-unwrapping/ But I see what you mean. It is possible to export each UV patch of my model as a different sub-object, where each vertex of the sub-object has one texture coordinate. Back on track ...

Re: [Paraview] Use existing texture map for 3D surface
Erm ... it appears I spoke in haste ... The some of the vertices of the objects I'm trying to texture have more than one texture coordinates. For example, refer to the right part of the screenshot (not mine): http://tinyurl.com/y3sqtbt You will see that vertices in the midline of the face gave two texture coordinates, while most of the others have just one. As such a per-face texture mapping will be required. And, from what I see of the example written out by Paraview, the one-vertex one-texture coordinate approach will not work in this case.

Hi Eric,
Thanks for the example. I've textured my very first sphere :)
I've taken another look at the VTK file format and I now realize that it
is possible embed extra scalar (UV) information in a VTK/VTP
file (I'm a novice, but I'm learning).
I've got a mesh with texture coordinates, and I can modify my external
VTP file writer to embed texture coordinates in my VTP file, so that the
programmable filter extracts it. Is this the correct approach? And will
the line:
Uarray = pdi.GetPointData().GetArray('U')
in your script extract U coordinates in the file?

- Olumide

But I'm not sure what other features have been implemented. The fact that we've gone from version 3.6 to 3.8 suggest that the current release has got a large number of new features. It would be nice to have a full feature list (just like Mozilla does with Firefox), so that users can know if any long-awaited features have been implemented.

[Paraview] Tab group in script dialog is not resizable
Hi,
The following screenshot is self-explanatory:
http://i17.photobucket.com/albums/b52/videohead/ParaviewScriptDialog.png
- Olumide
Possible memory leak in script dialog
I typically use python to load groups (sometimes up to a dozen) of VTK
files generated by each run of my experiment -- opening files manually
is very tiring. However, whenever I clear the currently displayed files
(using the "delete all" Edit menu option) Paraview never seems to give
back all the memory it allocated. As such, after loading and unloading
10-20 simulations, Paraview's memory consumption is so high that I
either have to terminate the program or it crashes.
Here's the result of my typical run. I saved a small simulation to a
state file and tried opening it and then clearing the data. The reported
data is from the Windows Task manager (for some weird reason the task
manager lists that the memory allocated to the Paraview process is
greater than the process' virtual memory!?)
Initial (new instance of Paraview):
Mem usage: 75,272Kb VM: 56,256Kb
After loading state file:
Mem usage: 89,512Kb VM: 70,224Kb
After deleting all objects
Mem usage: 84,476Kb VM: 65,132Kb
Another run, this time the python scripts are used to load the two
simulation datasets. Growth in memory usage is more aggressive:
Initial (new instance of Paraview):
Mem usage: 75,304Kb VM: 56,276Kb
After loading data set 1 via Python shell/script:
Mem usage: 113,264Kb VM: 88,704Kb
After deleting all objects
Mem usage: 114,456Kb VM: 89,688Kb
After loading dataset 2 via Python shell/script:
Mem usage: 126,116Kb VM: 101,196Kb
After deleting all objects
Mem usage: 126,284Kb VM: 101,388Kb
I'm aware that memory is dynamically allocated for the python shell and
GUI, and their corresponding objects are probably kept in memory to make
future launches of the python shell faster. This would explain why some
memory isn't returned after the initial launch. However as this should
done just once, the memory consumption should not grow each time a
dataset is loaded using a Python script/GUI.
Also, after deleting a dataset and a new one is loaded, the following
the message is frequently displayed.
qDrawShadeRect: Invalid parameters
qDrawShadeRect: Invalid parameters
qDrawShadeRect: Invalid parameters
..
qDrawShadeRect: Invalid parameters
qDrawShadeRect: Invalid parameters
A few other questions/suggestions:
1. Does the python command shell have a "run python script" command? For
example: RunPythonScript("C:/Work/Data/Foo.py"). Such a feature would be
a productivity boost. Clicking on the Tools menu and pressing the run
script button is okay for loading a few datasets but tiring when there
are lots of datasets to be evaluated. Also, it would be nice if the
python command were dockable, with an autohide feature like Visual
studio. Again this would be productivity boost. In fact it would be nice
if most views had an autohide feature. This would be a quick way of
increasing the size of the view window.
2. Does Paraview 3.6.2 have a disable offset feature as
proposed/discussed here (I've searched but I can't find one):

Re: [Paraview] Memory leak in Paraview 3.6.1(?)
Utkarsh,
I typically use python to load groups (sometimes up to a dozen) of VTK
files generated by each run of my experiment -- opening files manually
is very tiring. However, whenever I clear the currently displayed files
(using the "delete all" Edit menu option) Paraview never seems to give
back all the memory it allocated. As such, after loading and unloading
10-20 simulations, Paraview's memory consumption is so high that I
either have to terminate the program or it crashes.
Here's the result of my typical run. I saved a small simulation to a
state file and tried opening it and then clearing the data. The reported
data is from the Windows Task manager (for some weird reason the task
manager lists that the memory allocated to the Paraview process is
greater than the process' virtual memory!?)
Initial (new instance of Paraview):
Mem usage: 75,272Mb VM: 56,256Mb
After loading state file:
Mem usage: 89,512Mb VM: 70,224Mb
After deleting all objects
Mem usage: 84,476Mb VM: 65,132Mb
Another run, this time the python scripts are used to load the two
simulation datasets. Growth in memory usage is more aggressive:
Initial (new instance of Paraview):
Mem usage: 75,304Mb VM: 56,276Mb
After loading data set 1 via Python shell/script:
Mem usage: 113,264Mb VM: 88,704Mb
After deleting all objects
Mem usage: 114,456Mb VM: 89,688Mb
After loading dataset 2 via Python shell/script:
Mem usage: 126,116Mb VM: 101,196Mb
After deleting all objects
Mem usage: 126,284Mb VM: 101,388Mb
I'm aware that memory is dynamically allocated for the python shell and
GUI, and their corresponding objects are probably kept in memory to make
future launches of the python shell faster. This would explain why some
memory isn't returned after the initial launch. However as this should
done just once, the memory consumption should not grow each time a
dataset is loaded using a Python script/GUI.
Also, after deleting a dataset and a new one is loaded, the following
the message is frequently displayed.
qDrawShadeRect: Invalid parameters
qDrawShadeRect: Invalid parameters
qDrawShadeRect: Invalid parameters
..
qDrawShadeRect: Invalid parameters
qDrawShadeRect: Invalid parameters
A few other questions/suggestions:
1. Does the python command shell have a "run python script" command? For
example: RunPythonScript("C:/Work/Data/Foo.py"). Such a feature would be
a productivity boost. Clicking on the Tools menu and pressing the run
script button is okay for loading a few datasets but tiring when there
are lots of datasets to be evaluated. Also, it would be nice if the
python command were dockable, with an autohide feature like Visual
studio. Again this would be productivity boost. In fact it would be nice
if most views had an autohide feature. This would be a quick way of
increasing the size of the view window.
2. Does Paraview 3.6.2 have a disable offset feature as
proposed/discussed here (I've searched but I can't find one):

[Paraview] Memory leak in Paraview 3.6.1(?)
Hi - My typical work-flow involves generating a batch of VTK files, for which I also generate a python script for the VTK files. In preparation for the next simulation, I clear Paraview with the disconnect icon. My experience with Paraview 3.6.1 in this scenario is that, the memory consumption steadily grows, even though no objects currently loaded/displayed. Is there a way to configure Paraview so that it releases memory in the same way Firefox can be configured to use less memory (see for example http://windhair1000.blogspot.com/2009/03/how-to-fix-firefox-memory-leak.html -- BTW, I recently made these changed to my FF config, and it made a massive difference).

[Paraview] Communicating with a Paraview (GUI) server
Hi - I'm aware that Paraview operates/implements a client-server paradigm. This suggests that it may be possible for an external (e.g. C++ application) to communicate with a running instance of Paraview, by sending it commands (e.g. open legacy VTK file) via the port attached to the server. I'd appreciate pointers on how to do this.

[Paraview] Disabling polygon offset (z-fighting prevention) in Paraview
Hi - I use Paraview not for visualizing datasets, but for inspecting polygonal meshes and the operations I perform on them. My work involves computing various points and line segments on meshes, and I use VTK/Paraview to see if the points and line segments are where they ought to be (if not, I conclude that there's a bug in my code and then proceed to hunt it down). Why I use VTK for this task: VTK is the the only publicly available 3d graphics file format I'm aware of that explicitly supports and points, lines, and meshes, and has a viewer for viewing these entities. Most other 3d graphics file formats either support surfaces alone or have no ready-made viewers. Lately however, upon closer inspection, I've noticed that many of the points and line segments that I compute appear to hover above the mesh they are computed from and never quite touch it, and points never seem to lie on the line segments they are supposed to. For example, see: http://i17.photobucket.com/albums/b52/videohead/SurfaceError.png (note that the yellow line segment hover above the blue surface in the horizon) After much experimentation, debugging and consultation, I now suspect that this is caused by polygon offset in Paraview, designed to prevent z-fighting. I would therefore like to know: (i.) if my suspicion is correct i.e. Paraview implement polygon offset for preventing z-fighting in this case (ii.) if the above is true, how polygon offset can be disabled without recompiling the source Thanks, - Olumide ___ 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

[Paraview] [Bug?] Loading/importing a Paraview state resets the colors & representation of existing scene objects
Hi - I may have found another Paraview (3.6.1) bug -- not sure if it a bug or a feature, or if it has been reported. Basically, when a Paraview state is loaded into a non-empty scene, the color attributes of the existing objects are reset to the default white. Here's how to reproduce this bug (note, all the color changes below are done in the object inspector): 1. create a sample object e.g. a sphere, set its color (to red for example), and save the state to a *.pvsm file 2. Clear the scene and create a new object e.g. a cube, set its color (to blue for example), and its representation to wireframe. 3. Import/load the state saved in step 1. The process hides the blue, wireframe cube (nice feature). 4. Make the existing object visible. Result: its color has been reset to white, and its representation (from wireframe) to surface On the subject of color, here's something odd that I noticed. Again, it may be a matter of design but it seems a bit inconsistent to me. Its best demonstrated by the following two-part example: Part I: - create an object e.g. a sphere - set its (solid) color (to blue for example) - switch the representation to wireframe - Result: wireframe appears white! Part II: - Still in wireframe mode, set the ambient color to red - Switch to surface with edges' representation - Result: wireframe and surface appear blue!! BTW, I'm aware that color type in wireframe representation is given the name "ambient", as opposed to "solid" as in the surface representation. - Olumide ___ 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

[Paraview] [Bug?] Color information not saved/restored as part of state
Hi, Even in the simplest cases, Paraview (version 3.6.1) does not appear to save or restore color information about objects. The following simple case illustrates this problem: 1. Create a cube objects set its color to red, or any color other than the default 2. Save the state (File -> Save State) 3. Delete the builtin server (this is my favorite method of clearing a scene) and load the saved state 4. Box object appears in the default color, customized color information lost.

Re: [Paraview] Bug: saving screenshot with screen or print palette resets background color
I'm not sure if this has been reported/logged. This bug is easy to reproduce. Here's how to: 1. Open a new Paraview scene, and set the background color (to white for example) 2. Import or create a VTK object 3. Export screenshot with the screen or print palette. Result: the Paraview background color is reset to the default value. Update: This bug is affects more than just the background color. It also resets the wireframe color of a geometric object. Here's how to reproduce it: 1. create an object e.g. sphere primitive 2. set its representation to wireframe, and color to red (or any color other than the default) 3. set background to white 4. save screenshot with print palette Result: the mesh and background are reset to their default colors. In addition, the wireframe color of object in the screenshot is black. Note: this issue affects only objects with wireframe representations in a scene. Objects with surface or surface with edges representations in the same scene are unaffected, even though the background color is reset. ___ 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

[Paraview] VTK-Python script or Paraview server manager script?
Hello, Being a bit of a VTK/Paraview newbie, I'm having a little difficulty selecting the right tool for the job. I've got a number of polygonal primitives; lines, spheres, cylinders etc, in a 3d application and I would like to export and view these objects in Paraview. Because the 3d app is scriptable, I can write a plugin to export the primitives as VTK geometry data, but I shrink at the thought of handling low level operations that would be required. Therefore I'm considering another option namely: to have the 3d app write a VTK-Python or Paraview-Servermanager script based on the primitives in the scene. The problem now, is which scripting technique is better for the task, bearing in mind that what I would like to do is to view the primitives in Paraview. Initially, I started out writing a Paraview-Servermanager script, but I later realized that a VTK-Python script might do the job as well, _if_ VTK-Python scripts can export programmatically created scene data. Please advise.
