This subcategory includes the geometry classes, which describe the geometry of the data in space and time.
The Geometry3D class holds (see figure)
Geometry: Bounding box and transform
Geometry3D and its sub-classes allow converting between intrinsic coordinates (called index or unit coordinates) and word-coordinates (called world or mm coordinates), e.g. Geometry3D::WorldToIndex.
Every data object (sub-)class of BaseData has a Geometry3D, to be more specific, a TimeSlicedGeometry, to be accessed by BaseData::Get TimeSlicedGeometry(). This is because data objects are objects in space and time. The data values are often stored in intrinsic coordinates, e.g., integer pixel/voxel or time indices. The information required to convert these intrinsic coordinates into a physical world coordinate system, with coordinates in millimeters and milliseconds, is stored in Geometry3D class and its sub-classes.
TimeSlicedGeometry describes a geometry consisting of several geometries which exist at different times. It contains a list of Geometry3D instances to be accessed by TimeSlicedGeometry::GetGeometry3D(t), with t between 0 and TimeSlicedGeometry::GetTimeSteps().To convert between world-time in milliseconds and the integer timestep-number use mitk:TimeSlicedGeometry:: MSToTimeStep, for conversion in the opposite direction mitk:TimeSlicedGeometry:: TimeStepToMS.
Often all Geometry3D instances contained in a TimeSlicedGeometry have the same duration of life. The initialization for this case can be done using TimeSlicedGeometry::InitializeEvenlyTimed(Geometry3D *geometry3D, unsigned int timeSteps). The Geometry3D parameter must have a limited life span set by Geometry3D::SetTimeBounds(). It is used as the first Geometry3D contained in the TimeSlicedGeometry (thus returned by TimeSlicedGeometry:: GetGeometry3D(0)). The next one will start to live immediately at the end of life of the first. The bounding boxes and transformations are copied. The instance of Geometry3D provided to TimeSlicedGeometry::InitializeEvenlyTimed is referenced, not copied!
TimeSlicedGeometry is a Geometry3D itself. Its bounding box and transformation is usually the same as the bounding box and transformations of the contained Geometry3D instances. Its life span (to be accessed by TimeSlicedGeometry::GetTimeBounds()) is the span from the beginning of the first contained Geometry3D to the end of the last contained Geometry3D.
TimeSlicedGeometry can also contain Geometry3D instances that do not have the same bounding box and transformation. In this case, TimeSlicedGeometry::GetEvenlyTimed() has to be false.
SlicedGeometry3D is a sub-class of Geometry3D, which descibes data objects consisting of slices, e.g., objects of type Image (or SlicedData, which is the super-class of Image). Therefore, Image::Get TimeSlicedGeometry() will contain a list of SlicedGeometry3D instances. There is a special method SlicedData::GetSlicedGeometry(t) which directly returns a SlicedGeometry3D to avoid the need of casting.
Geometry instances referring to images need a slightly different definition of corners, see Geometry3D::SetImageGeometry. This is usualy automatically called by Image.
Comparable to TimeSlicedGeometry the class SlicedGeometry3D contains a list of Geometry2D objects describing the slices in the data object. Instead of time steps we have spatial steps here from 0 to GetSlices(). SlicedGeometry3D::InitializeEvenlySpaced (Geometry2D *geometry2D, unsigned int slices) initializes a stack of slices with the same thickness, one starting at the position where the previous one ends.
Geometry2D provides methods for working with 2D manifolds (i.e., simply spoken, an object that can be described using a 2D coordinate-system) in 3D space. For example it allows mapping a 3D point on the 2D manifold using Geometry2D::Map. The most important sub-class is PlaneGeometry2D, which describes a planar rectangle.
Image has a TimeSlicedGeometry, which contains one or more SlicedGeometry3D instances (one for each time step), all of which contain one or more instances of (sub-classes of) Geometry2D (usually PlaneGeometry2D).
As a reminder: Geometry instances referring to images need a slightly different definition of corners, see Geometry3D::SetImageGeometry. This is usualy automatically called by Image.
