# General

1. ## Drag and Drop for states and plugins

Paraview can handle drag and drop for data files (great feature) but not for state files.
Also make drag and drop working for plugins. (copy the plugin file to some safe place .config/... and check the Auto Load). This can make using plugins much easier for new people.

And have a central place (wiki maybe) with a list of the community plugins (compiled or in source).

Great job and Merry Christmas to all.

2. ## abaqus

I suggest to add the ability to read Abaqus files (.odb). After all it is a very popular code, and this way the post processing would also be possible on Linux/Mac.

3. ## check parallel execution under Win 7

Parallel execution seems not to be working under Windows 7 64 bit

Only one core used even if "enable multicore for data processing" is ticked

Thanks

4. ## cell volume

It would be great to have a filter that directly computes cells volume and store it as a variable

5. ## Represent filled volume

Adding functionality to represent a 3D object filled.
After using slice for example only the contour line is showed of a sphere. The representation mode volume instead of surface would be nice.

6. ## Export Dynamic Scenes

Add capabilities to the VRML, WebGL, X3D etc. writers to enable the export of animated scenes.

7. ## Reimplement the render-node-port option

I have in vain looked for th e (documented) render-node-port option in recent PV releases (4.1, 4.2) and cannot find it. Presently it seems that data- and render-server connection is mandatory random. This makes it more or less impossible to connect DS on cluster nodes to RS on e.g. a workstation. An otherwise quite efficient solution when reading parallel OpenFOAM data.

8. ## Integrate Julia

I think that Julia is the next best scientific programming language. CFD, FEM, Magnetic, and other solvers, as well as filters could be written right inside Paraview, and executed with decent performance. The same code can be developed as stand-alone functions.

9. ## Add Custom View toolbar shortcuts

You know, like the +/- X, Y, Z shortcuts...

10. ## Volume fraction "histogram"

A filter to divide a dataset into different ranges for a particular variable that has for output each range in the X axis, and the volume that corresponds to each range in the Y axis.

For example, I am doing mixing tank CFD simulations, and I am interested in understanding how much of the volume of the tank is at different ranges of velocities. The way I do it now is to manually create thresholds for each range, and then integrate variables.

11. ## Global Z scale option

Allow a global z scale like Google Earth. Currently I have to scale each of dozens of input data individually. This is an important feature for terrain visualizations.

12. ## Setting zoom sensitivity

Scale the speed at which zoom occurs based on mouse input. In other words, add a user preference for scaling how rapidly or slowly the scene zooms in or out based on moving the scroll wheel. My mouse seems extremely sensitive.

13. ## obj (with texture) can be used...

I would like to know if it's possible to used obj format with the textured file, in order to create "fly in" or "fly through" animation of the model. Actually obj file could be used but the textured file is not used

15. ## Add new color palettes

ParaView comes with two built in color Palettes: Screen and Print. It would be nice if a user was able to define his/her own color palette.

16. ## Vivid (Flat) Color Contours like Fluent or other Postprocessors

All contours on ParaView are always shaded, but sometimes the shaded contours are not suitable for understanding the values indicated by colors. I hope the vivid, flat, non-photorealistic shading model like Fluent or other post processors are implemented.

17. ## Enable vector export of axis labels specified in MathText form in line chart views

Currently (as of version 4.1), when exporting line chart views in vector form, the mathtext axis labels get output in plain form such as $\gamma$ instead of the Greek gamma symbol. Mathtext apperaing elsewhere, such as legends, gets output correctly. Only the axes labels do not get output correctly. I have tested it with both "renedr text as paths" checked and unchecked and the error was not affected by it.

18. ## Enhancements for Resample With Dataset filter

It often happens on CFD analysis that you want to resample large data file (like a complicated.foam case) on .stl or other kind of geometry files. But when you do this with Resample filter, you loose all the previous present celldata or pointdata (for example the STLSolidLabeling on an stl file useful do subdivide them). The Resample With Dataset filter could be improved by adding a (flag) option like "Append Already Existing Source Data", thus not missing already present dataset on Source vtkDataSet

19. ## SEG-Y seismic data reader (2D and 3D)

It would be useful to have a reader for SEG-Y seismic data, with the option to translate between big-endian and little-endian forms (UNIX to PC). This may be a complicated task since most data will be in two-way time (unless depth converted). However , this should not be a problem given that the freeware GMT software can read the data and convert to a useable format. Something to consider.

20. ## Faster Auto Apply

As of now I'm using auto apply with a transformation like widget however I'm unable to see smooth real time changes. I know the paraview pipeline is complicated but I would like to see a way to allow for realtime editing of the dataset be it a different sort of plugin or a faster way to do auto apply.
