qmlalembic's Introduction

qmlAlembic - Alembic QML plugin for Qt3D

qmlAlembic is a C++ QML plugin providing classes to load and visualize Alembic point cloud files in Qt3D. It has been developed to load AliceVision sparse reconstruction results inside Meshroom.

For now, it only handles point clouds and cameras.

Continuous integration:

Windows:

License

The project is released under MPLv2, see COPYING.md.

Get the project

Get the source code:

cd qmlAlembic

See INSTALL.md to build and install the project.

Usage

Once built and with the plugin installation folder in QML2_IMPORT_PATH:

qmlalembic's Issues

Building Error?

I’m assuming I need the QT 5.11.1 for windows(2.4 GB) installer from here
https://www1.qt.io/offline-installers/?hsLang=en to install the proper qt5? Also, can visual studio 2017 be used to build this? Most of what I’m seeing in the code says visual studio 2015.

ILMbase errors

Hello; trying to build this project and, when I run cmake, I see the following errors. I tried editing the CMakeLists.txt file as advised here, but unfortunately that fix does not seem to work in this case.

vcpkg Alembic

Hi, hope i'm not interrupting with anything, I'm not fluent in building sollutions at all. But i was following the INSTALL steps, and ended up on this error.
I tried to go around using cmake gui, and putting all necessary files by hand, but in the end the build process in VS comunitty failed, in some point. I'm not sure if this is the right way of seeking sollution. If not fell free to del this post.

Could not find a configuration file for package "Alembic" that is
  compatible with requested version "1.7".

  The following configuration files were considered but not accepted:

    D:/vcpkg-git/installed/x64-windows/share/alembic/AlembicConfig.cmake, version: 1.7.8 (64bit)

If there is anyone willing to help me go through the process of compiling this I would appreciate.
I would be glad to point some remarks to INSTALL.md to help a little green newcomers like me.

.abc format unknown

Hello,
I have built AliceVision and trying to run Meshroom to see the output. I can run till the SfM part but whenever I run PrepareDenseScene from the UI, I get error and the log is below:

Program called with the following parameters:
 * input = "/tmp/MeshroomCache/StructureFromMotion/1791bc36ef6221756d0020876349789a691bd297/sfm.abc"
 * output = "/tmp/MeshroomCache/PrepareDenseScene/4e7505e5bff4c13bdaf8439604ad549d2dc7314c"
 * verboseLevel = "info"

[14:17:29.879224][error] Unknown input SfM data format: '.abc'
[14:17:29.879249][error] The input SfMData file '/tmp/MeshroomCache/StructureFromMotion/1791bc36ef6221756d0020876349789a691bd297/sfm.abc' cannot be read.

Looking at the log it looks like it's related to Alembic and I have built qmlAlembic successfully and put the install prefix in my path already. But I still get this error. Could you please take a look?

Thanks,
Ahmad

Qt 5.14.1 support

Hi,
I spent 2 days trying to use qmlAlembic with Qt 5.14.1 (also 5.13.1) and it doesn't work. I installed it with cmake, qmake (my own .pro file), even tried with copying all source to project and building all together - always same effect which look like this:
Cannot assign to property of unknown type "" (Qt 5.14.1)
Can not assign value of type "<unknown type>" to property "entity", expecting an object (Qt 5.13.1)

Error comes from
QQmlPropertyValidator::validateObjectBinding(QQmlPropertyData*, QString const&, QV4::CompiledData::Binding const*) - qqmlpropertyvalidator.cpp inside qtdeclarative module.

It seems like some problem with reading plugin metadata. I tried to debug inside qt source but after my own compilation there were plenty of other problems. Did anyone face something similiar? Should qmlAlembic work with newer Qt Versions than 5.11?

But when I run Meshroom I don't have this plugin.

By not providing "FindAlembic.cmake" in CMAKE_MODULE_PATH

I met the error when i build qmlAlembic following the guide

CMake Deprecation Warning at CMakeLists.txt:12 (cmake_policy):
The OLD behavior for policy CMP0043 will be removed from a future version

The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.

CMake Error at CMakeLists.txt:26 (find_package):

CMake did not find one.

Could not find a package configuration file provided by "Alembic"

AlembicConfig.cmake
alembic-config.cmake

Add the installation prefix of "Alembic" to CMAKE_PREFIX_PATH or set
"Alembic_DIR" to a directory containing one of the above files. If
"Alembic" provides a separate development package or SDK, be sure it has
been installed.

See also "E:/SoftInstall/Qtplugins/qmlAlembic/build/CMakeFiles/CMakeOutput.log".`

But i have installed alembic using vcpkg when i build alicevision,and the path containing AlembicConfig.cmake is E:\vcpkg\installed\x64-windows\share\alembic\AlembicConfig.cmake .
I have no idea how to add the Installation prefix of alembic to CMAKE_MODULE_PATH ,anyone suggestion will be appreciated!
