MITK 1.4 Key changes from version 1.3
(1) New Shear-Warp volume rendering algorithm(supports cropping, clipping, shading, MOP and LOD),including mitkVolumeRendererShearWarp (main algorithm class), mitkVolumeShearFunction and its sub-classes;
(2) New mitkSimilarity2DTransform class: to apply similarity 2D transformation in 2D image space;
(3) New mitkSubtractImageFilter class: to apply subtraction of two volumes, can be used to verify registration precision of two images;
(4) mitkImageModel class: add support of displaying large size 2D image without GPU texture limit;
(5) Structure and efficiency improvement of mitkVolumeRendererTexture3D class;
(6) Parameters and effect improvement of mitkVolumeRendererSplatting class;
(7) Improvement and update of the registration framework, including the changes of mitkInterpolateFilter and its sub-classes, mitkOptimizer and its sub-classes, mitkMetric and its sub-classes, mitkTransform and its sub-classes, mitkRegistrationFilter, mitkResampleFilter,and mitkGaussianDerivativeImageFilter;
(8) Improve sub-classes of mitkVolumeRenderer (mitkVolumeRendererRayCasting, mitkVolumeRendererRayCastingLoD,mitkVolumeRendererSplatting,mitkVolumeRendererShearWarp) to support reslicing and pseudocolor functions of mitkReslicePlaneWidgetModel in volume rendering, now all concrete volume renderers support interactive volume clipping and can display correctly under most circumstances, please see the "VolRen" example at Examples\\"VolRen\" for details.
(9) Add two volume renderer switcher (shear-warp and splatting) and a toolbar menu (delete selected reslice widget)to the "VolRen" example at Examples\\"VolRen\";
(10) Fix bugs of mitkQEMSimplification algorithm;
(11) Fix other small bugs found in MITK 1.3.
