VTK 9.0 Support #4096

pionex · 2020-05-14T03:07:12Z

This code allows PCL master to compile and generally run with VTK 9.0.0. Some attempt was made to allow this code to be backwards compatible with older versions of VTK, although that has not been fully tested.

The main cmake has been updated to work with the breaking new conventions and has some backwards compatibility. It will not currently work with QT support with an older version of VTK, however.

The visualization cmake has been modified to call the new vtk_module_autoinit functionality. In my testing, so far I have only found that this needs to occur to make the visualizer work, but its possible other vtk modules need to be initialized for additional targets.

The changes made vtkCellArray usage in pcl_visualizer in the add/update polygon mesh functions are still being tested. There was some commented code that I used to make this compile, but I don't know if this fully works or offers the best performance.

The vtkIdType * were changed to vtkIdType const * where necessary to support the new API, although the VTK documentation recommends to use iterators instead if possible.

Version 2 of vtkCellArray deprecates the write pointer and requires const pointers in in some api calls that return pointers to shared memory. If the VTK_CELL_ARRAY_V2 macro is defined, this code uses the appropriate const pointers and uses alternative methods to insert cells into the cell array. This commit also adds some missing vtk headers that were causing incomplete type errors.

Please extract out this type. Sample code

Is the point of extracting this out to eliminate multiple ifdefs everywhere its used?

I was searching for a good common place to define this type, but there doesn't appear to be any common header file. Should it be (re)defined in each module where its necessary?

I'm assuming you mean something like:

#ifdef VTK_CELL_ARRAY_V2 using vtkCellPtsPtr = vtkIdType const *; #else using vtkCellPtsPtr = vtkIdType*;

I am also looking into using iterators and it seems straightforward, but this change is still required

Sorry, I seemed to have missed this conversation.

👍

Should it be (re)defined in each module where its necessary

That wouldn't be ideal. A single new header somewhere would be better, but I also don't know where.

VTK documentation recommends to use iterators instead if possible

Perhaps using iterators is a better way to go forwards. We can split the logic using macros from when iterators first came to VTK API and use the current logic for older VTK. This can allow us to make decisions such as stopping support for old versions: VTK 7 and higher are available on all platforms being targeted.

It will not currently work with QT support with an older version of VTK

~~Should I mark this PR as draft or are you looking for feedback from PCL to add this support?~~

PS: The CI will be red since we look for VTK 6 and 7 on Ubuntu

I don't know if this fully works or offers the best performance

Note for others: Needs testing

larshg · 2020-05-16T20:15:39Z

Hey Pionex

I'm testing your branch out and I have done a few cmake changes.

But I can't get it to compile. I get a bunch of:
'vtkSmartPointerBase &vtkSmartPointerBase::operator =(const vtkSmartPointerBase &)': cannot convert argument 1 from 'T *' to 'vtkObjectBase *'

Did you get this?

Edit: I'm on win10 using VS2019.

larshg · 2020-05-16T20:37:59Z

It was missing includes, that probably was transparently included... VS is not so forgiving 🙄

Added PR to @pionex 's PR.

Reorganise to hopefully support pre 9.0.

@pionex I have tested with my vtk 8.2 system and made a few changes. Please merge it and lets fix the last things mentioned by @kunaltyagi.

larshg · 2020-05-26T19:32:45Z

@pionex ~~where is VTK_CELL_ARRAY_V2 defined?~~ - Nm - found it.

pionex · 2020-05-26T19:44:50Z

I can have a look at this in a few. How much longer will you be working on it today? I’m in GMT+12, so day is just starting.

larshg · 2020-05-26T19:56:10Z

I'm off to bed now so go ahead. You can look if the ci is green with my latest push to my pr also.

I was thinking of making a compat header in visualization and then those that can use this will(visualization and all that depends on visualization).
The rest ie I/O and surface.. maybe more cant remember I would leave as is with the if defs.

There is no common sub module which imports vtk and it seems overkill to make such project for a few extra if defs.

Maybe add a space after the colon 🙂

It was more for 'debugging' - but I guess the information is nice to have, but could probably be consolidated to a single line summerizing most of the VTK settings 😄

There was an issue about producing a full-blown CMake configuration report for PCL, maybe it's the kind of information that could go there when it happens.

https://cmake.org/cmake/help/v3.17/module/FeatureSummary.html

That's something nice and available in 3.5 too (Ubuntu 16.04's CMake version)

@Morwenn is there a issue for this CMake reporting?

@kunaltyagi I thought so but apparently it was merely a comment in issue #3603, my memory failed me. Such a summary is definitely something valuable when dealing with build issues (and especially good when users report issues, you don't have to ask again and again for the information). I didn't know that CMake had a built-in feature to report the options, that's nice.

larshg · 2020-06-13T18:36:10Z

@pionex have you done any work - feel like we are close to make it possible to merge? If you are busy I don't mind picking it up and try to complete it.

Please go ahead. I wasn't sure where to put the new headers.

This warning might also be something to look into:
vtkOpenGLPolyDataMapper::SetFragmentShaderCode was deprecated for VTK 9.0 and will be removed in a future version. Use vtkOpenGLShaderProperty::SetFragmentShaderCode instead

Do I need to do anything on github for you to pick it up?

Indentation of set is missing.

Is it really necessary to have two lists? I had started more than one moth ago same test (just didn't had time to continue and as this PR also exists)...

I had solved it by:

function(checkVTKComponents) cmake_parse_arguments(PARAM "" "MISSING_COMPONENTS" "COMPONENTS" ${ARGN}) set(vtkMissingComponents) if (VTK_VERSION VERSION_GREATER "8.2") foreach(vtkComponent ${PARAM_COMPONENTS}) if (NOT TARGET VTK::${vtkComponent}) list(APPEND vtkMissingComponents ${vtkComponent}) endif() endforeach() else() foreach(vtkComponent ${PARAM_COMPONENTS}) set(vtkComponent "vtk${vtkComponent}") if (NOT TARGET ${vtkComponent}) list(APPEND vtkMissingComponents ${vtkComponent}) endif() endforeach() endif() set(${PARAM_MISSING_COMPONENTS} ${vtkMissingComponents} PARENT_SCOPE) endfunction() set(PCL_VTK_COMPONENTS ChartsCore CommonCore CommonDataModel CommonExecutionModel FiltersCore FiltersExtraction FiltersModeling ImagingCore ImagingSources InteractionStyle InteractionWidgets IOCore IOGeometry IOImage IOLegacy IOPLY RenderingAnnotation RenderingLOD ViewsContext2D ) # Start with a generic call to find any VTK version we are supporting, so we retrieve # the version of VTK.

I'll look into using your snippet.

Originally it was using List transform, but that wasn't available. But an "ordinary" foreach could be used ofc.
