MeVisLab Release Notes before 3.0

Fixed some suboptimal import configurations of DICOM NM data.

Improved performance bottlenecks of non-DICOM-Imports with DirectDicomImport which make use of ITK loaders.

Commented risks of deactivated "Decompose MultiFrame Files" in the help of DirectDicomImport.

Fixed exceptions when exporting 2D DICOM frames manipulated with DicomModifyImageTagsPlugin which have an empty NumberOfFrames tag.

Some of the defaults for network appearance and network interaction have been changed. If you don't like the new defaults, you can change them back in the Preferences dialog.

Modules in the network view now show small message indicators for warnings, errors, etc. besides the modules, which makes it easier to discern which module produced which messages.

Connections can be moved in the network without pressing Shift.

Implemented dropping of modules on other modules or connections to create a connection.

Show small Inventor connectors instead of rectangles when dragging Inventor fields to a Group/Separator. This way it is more obvious that you can add a connection between existing connections.

Allow to disconnect connections from the context menu of network connections.

Also allow to disconnect connections by selecting them in the network and pressing Delete/Backspace.

Make more network interaction undoable.

Status visualization of image input/output connectors by colors now extends to Base fields, too, if activated (a connector turns red if no Base object is set on the field).

The tooltip for Base field connectors now shows the type name for Python and VTK objects.

Entering an empty name when renaming modules will set the default name.

Video generation in MeVisLab (e.g., from the Screenshot Gallery) now uses OpenCV on Windows and Linux.

Module groups are now retained when creating a local macro from part of a network.

When creating a local macro you can't promote it to a global macro anymore. This didn't always work correctly.

You can now select a target directory in the dialog for creation of local macros.

Added a keyboard shortcut editor to MeVisLab and MATE.

The user can take screenshots of the current network with the F12 key.

The default dock layout of the IDE has been changed to a more sensible default.

Fixed problems with destroyedCommand on reloading of a module.

Added the methods voxelVolumeInCubicMillimeters and voxelVolumeInMilliliters to MLABImageField, which return the correct volume for sheared images.

Added new field wrappers for ml::Vector6Field, ml::ImageVectorField, SoSFVec2s, and SoSFVec3s. Previously a MLABStringField would be used for all these parameter types.

MeVisLab now supports a new directory structure for modules: under the Projects directory (which is located directly in a package directory), sub-directories can have a Modules, Sources, TestCases, and GoogleTests directory, thus combining all sub-directories of a project.

The new multi-threaded ML host is now the default.

The restrictions for unlicensed use have been changed. The number of self-defined modules that can be used at the same time has been reduced to 5, but at the same time it is now possible to use regular Python scripting in modules with a file size of up to 2KB per module. This allows to check out the Python-specific features of MeVisLab like the debugger or the new Pylint integration. Note that the import of self-defined Python modules is not possible without a license.

Modules can now inherit field documentation from prototype modules. This only works for ML or Open Inventor modules and requires that there is a module with the same name as the parent class of the inheriting module (as registered with the ML or Open Inventor class system). Invisible dummy modules can be added to the helpPrototype module group.

Added -userscript command-line option for executing user scripts from the command-line.

Improved number display for numbers with exponent or in too narrow widgets: The numbers are abbreviated to fit in the visible space and exponents are displayed in a more natural, non-programmer way (only while not editing).

Python code completion has be rewritten using the jedi Python library. It supports much better completion on any Python object and the PythonQt wrappers. Hovering over text in Python now shows a tooltip with type information. Overload completion works much better now and only shows the matching signatures, depending on the current argument position. Goto reference and goto assignment have been added to the context menu. Completion now even works on script wrappers that are returned via MLABMLBaseField::object().

Context sensitive help in Python code has been improved. All major script libraries are now supported, pressing F1 (or context menu Show Scripting Help) on a selected variable will show correct help pages for: Python statements and base libraries, NumPy, VTK, OpenInventor, OpenCV, MLAB, etc.

Added Find in Files and Replace in Files support to find dialog.

Added option to Find&Replace dialog to replace all in selection.

Introduced a new graphical scrollbar similar to "RockScroll" (which can be deactivated).

Added new renderer module SoWeightedBlendedOIT as a faster alternative to SoDepthPeelRenderer.

Introduced a new general GLSL shader pipeline framework which supports a flexible way to build reusable shader functions and surface shaders, while interacting correctly with existing Open Inventor lights and fixed function state. It allows to separately modify the light model (BlinnPhong, Phong, Lambert, or your own custom model), the surface shading and how fragments are stored or discarded (for Depth Peeling, Ambient Occlusion, etc.).

The new module SoPointSpriteRenderer allows to render hundreds of thousands of correctly shaded spheres without generating a mesh geometry using OpenGL point sprites. The So3DMarkerEditor now offers a PointSprite render mode, which makes use of the SoPointSpriteRenderer to render huge amounts of markers as spheres.

The SoDrawInstanced module allows to render the same geometry multiple times with different color, scale, rotation, and translation. It uses instanced draw array/elements OpenGL calls on hardware that supports it and automatically falls back to multiple draw calls on older hardware. The module supports all Open Inventor geometry nodes that support VBO rendering.

The new GLSL post effect framework offers a complete OpenGL post effect framework for Open Inventor. It supports various screen-space post effects: FXAA antialiasing, ambient occlusion, glow, edges, depth halos, and custom effects. Have a look at the various example networks!

The SoDiagram2DCursor cursor position can be set from the outside now.

Print an error message when SoGVRRenderer is used below a depth peeling module - this is unnecessarily slow and should be avoided.

MLAB_ENABLE_QA_RELEVANT_WARNINGS = 1

If this is not empty, all warnings considered useful for QA relevant code are enabled.

MLAB_HANDLE_QA_RELEVANT_WARNINGS_AS_ERRORS = 1

If this not empty, warnings which normally can be removed easily are handled as to errors. Especially in older projects a few warnings still appear in large amounts and cannot be removed without greater effort. These warnings are tolerated although they are not wanted any more.

MLAB_HANDLE_ALL_QA_RELEVANT_WARNINGS_AS_ERRORS = 1

This is the preferred setting which switches all warnings to error and guarantees warn-free code. It should be used for new developments and preferably for all projects which can be ported.

#include <mlSystemWarningsDisable.h>

#include <TheThirdPartyInclude.h>

#include <mlSystemWarningsRestore.h>

Open Inventor events now get their double-click and auto-repeat flags from the operating system (previously double-clicks were self-detected).

DirectDicomImport and related modules:

C++-tool and module libraries and public sources:

ITK has been upgraded to version 4.1 from January, 31st, 2012, 12-05pm MET from the master GIT repository from http://www.itk.org. Basically FFT and deconvolution related functionality has been added by wrapping 52 new itk classes. 8 wrapped modules have been removed and 4 renamed. Some missing Get-functions and macros as well as some warnings have been fixed in the ITK-third party for that purpose. For the list of changed modules and further details please read the technical notes referenced in the help file of any modules wrapping itk classes.

VTK has been upgraded to version 5.10.0 from April, 28th, 2012, 18:08pm (MET) with tag "v5.10.0 rc 1" from GIT repostory from http://www.vtk.org. 156 new classes have been wrapped and 4 have been removed. Some missing Get-functions and macros as well as some warnings have been fixed in the VTK-third party for that purpose. For the list of changed modules and further details please read the release notes referenced in the help file of any modules wrapping vtk classes.

Added new module DicomFrameTagInfo and improved module DicomFrameSelect.

DicomTagModify got an alternative interface for modifying an unlimited number of tags.

Added a SUM mode for MergeRegions

Added an optional input for a vector image in MaskToMarkers

Added new output inspector for StylePalette.

Added new module DynamicStylePalette with a flexible number of entries.

Extended remote rendering to also send whole module panels (but without OpenGL viewers).

RasterFunctions module can generate a list of functions for an input XMarkerList.

RegionGrowing and RegionGrowingMacro now allow to select the precision of the internal image data representation (previously always 14 bits). This improves threshold accuracy and/or memory efficiency in certain cases.

Added new macro module HTTPFileDownload.

Fixed the problems that some macro modules had with file paths containing non-ASCII characters.

Added new module CompoundMatrixArithmetic for calculation of arithmetic expressions for several 4x4 matrices.

For backwards compatibility, INSTALLDIR/data is still used if it exists and is non-empty.

There are new FME-modules and projects in the public sources providing efficient implementations of often used standard algorithms, demonstrating some new image processing features of the ML, or allowing for a closer look into the binding of VTK modules to MeVisLab or into the programming of plugins for DirectDicomImport:

Additional SDK-Interfaces:

Fixed MLReplaceDeprecateAPI helper module.

VoxelizeInventorScene was not correctly restoring the Open Inventor state. Updated documentation.

CSOConvertToImage: values of CSOVoxelSet voxels are now filled with image values if the module should use image values.

CSOVoxelSets now retain the voxel-to-world-matrix of the source image that is used in CSOVoxelSetToMarkerList to create correct world marker positions.

The GVR renderer used GLSL shader code which caused an ATI driver crash on some ATI cards/drivers. The GLSL shaders have been modified so that the standard GVR slicer shaders used in View3D etc. should work again. The new GVR ray cast shaders and some advanced slicer shaders will still have the problem. Since this is an ATI driver bug, we filed a bug to ATI. Hopefully this will be fixed in a future ATI driver version.

View3D: Avoid clipping the annotations.

Fixed Snippets List feature by using a dummy image if no screenshot could be created (e.g. because of an insufficient OpenGL driver).

Added a MEVISLAB_VERSION define, current value is 202.
