A script to check simple things like if the class the plugin is using actually exists and if the functions that are supposed to be called actually exist. It would be nice to know these things before errors occur at runtime :)

Paraview is supposed to be good at parallel task. But I don't understand why when I use a *.pvd file to load a parallel dataset consisting of several Rectilinear blocks, with volume rendering Paraview only renders only one of the blocks at a time and not all of dataset. It is good to have this resolved because I think volume rendering is one of the Paraviews interesting features.

Add a snapping function for sources, i.e. when creating for example splines, snapping of control points to re-existing features on the pipeline would be useful.

Add scroll bar to the 'Fix Paths in State File' GUI so that the GUI does not extend beyond the edge of your monitor making it impossible to fix the path names associated with a session for the files that are forced outside of the extents of the monitor.

This view should take a 2D dataset and render it as a carpet plot using a custom mapper to avoid the memory cost of converting it to polydata and warping it. It should also have decent x-y-z axis.

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.

I find it much more intuitive when ZOOM IN is done by rolling the mouse roller towards myself, and ZOOM OUT - away from myself

embed a thumbnail screen capture that was taken at the time state was saved. Then use this embedded image in the file open dialog as a preview.

Adding the possibility of reloading result files while mantaining the setup of a saved state, in order not to have to specify filters, windows and all this stuff, would be a nice function that will save post-procesing time.

By the way, ParaView is an extraordinary post-processor! thank's for putting it in open-source regime.

This could be very useful for those who want to interactively deform and visualize resulting meshes, similar to what is professionally available in many CAD packages. Simply click on a surface and extrude, or click on a mesh vertex and reposition

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

It is very hard, or almost impossible to edit the transfer function in small areas of the data range using the point UI window. What's missing is the possibility to zoom the point edit window so that just a portion of the data range is displayed, and existing points in that area can be edited more easily. When in zoom mode, the ability to pan that sub-view through the data range would be great to have as well.

.off files are great to read and write.

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

Import georeferenced image as a flat surface in 3D or texture

Currently grid names are not imported during XDMF import. This would be very useful in case of multi-block data, where currently generic names are assigned. See also this post:

Hello,

When I create a vector plot, the plot returns with three arrows representing each point instead of one arrow. How can I change from three arrows to one arrow?

Enable customization of the 2d Gliph with a custom user's image

Paraview python shell is difficult to use with Anaconda distributions in Linux. The shell don't see the PYTHONPATH to Anaconda or other secondary python distributions not in /usr/lib... That makes difficult to use external python modules

$ export PYTHONPATH = /mypath works with pvpython but not in the python shell in Tools/Python shell
