FIX #0442: Volume Rendering quality is low compared to ImageVis3D
Comparing volume rendering of the same dataset and the same transfer function, shows a lower quality compared to ImageVis3D. The UseCompressedTexture flag was set to true in the MITK volume rendering mapper (GPUVolumeMapper3D). Changing it to false, changes the quality to the same level as ImageVis3D.
ENH #0441: Import transfer function from ImageVis3D to compare volume rendering
Transfer Function editor allows importing a transfer function from ImageVis3D software. This allows to compare the volume rendering applied to the same object. For example, a sample data set has been used to compare the volume rendering.
ENH #0439: Is difficult to configure volume rendering for an image
The name of the volume rendering transfer function is not very descriptive and there are a lot of controls. To reduce this complexity, a snapshot has been added for each transfer function and the controls are grouped by its functionality.
ENH #0438: Cannot see all available tools in plugin selector
In the plugin selector, the GIMIAS plugins are shown as items with just the name of the plugin. Is not possible to know what are the available tools in each plugin. For example, in the MeshEditorPlugin, there are a lot of tools for mesh editing. For the end user, is difficult to search a specific tool that is available in the GIMIAS plugins.
In order to facilitate this, all GIMIAS plugins will show the available tools as children items. When clicking on a specific item, the description and the online documentation will be shown at the bottom.
FIX #0417: GIMIAS takes 20 sec. to start in debug mode
Enabling just the MITK and SceneView plugin, GIMIAS takes 26 seconds to start in Debug mode. It will be interesting to reduce this start-up time for developers that are working on a GIMIAS plugin.
To analyse the start-up, the VS2010 profile tool has been used. Most of the time is taken when initializing OpenGL. In order to reduce this time, one option is to execute the different plugin providers in parallel in a secondary thread and send to the main GUI thread the GUI tasks. Initial tests show that this can reduce the start-up time to 15 seconds (42% of reduction).
The main window will be the responsible to update all the plugin providers. It will delegate the responsibility to the class PluginSelectorWidget. When the providers needs to be updated:
- Adds an observer to each provider, that is derived from the class BaseProcessor and sends it for background execution
- Executes the function OnStartLoading( ) to initialize framework before loading plugins
- The provider will scan the plugins
- When the plugins are going to be loaded, - this task should be executed by the main GUI thread - it will call the function UpdateOuptut( ) for each plugin
- The main GUI thread will receive the information about the plugin to load/unload using a blTagMap and call the function LoadPlugin/UnLoadPlugin for the current provider.
- Executes the function OnStopLoading( ) to initialize framework after loading plugins
The information messages will be sent to the main GUI thread using the UpdateCallback class and the function AddInformationMessage( ).
ENH #0402: Integrate MSV working area with metadata information
MSV working area allows visualization of data objects using tool tips and VTK buttons to navigate. Read more in MSV Plugin.
ENH #0407: Add preview image for DataEntity
The interface class Core::DataEntityPreview is used for managing a preview image of a DataEntity. A concrete implementation is MITKPreview that uses wxImage to store/load/save the preview.
When a DataEntity is created, it searches the FactoryManager for an implementation of DataEntityPreview interface class and creates an instance.
The preview image is loaded/saved when the DataEntity is loaded/saved.
This class is used in MSV Plugin.
