[0030] 本实施例中,所述主窗口下具有三个文档视图体系,分别为文档I以及与之相关联的视图1、文档2以及与之相关联的视图2、文档3以及与之相关联的视图3;其中以地震数据为例,列出了文档I中包含的多种不同类型的数据对象,如剖面数据、井数据、层位数据、断层数据、岩性数据等,以及视图1中包含的与数据对象相关联的不同类型的显示对象,如剖面显示对象、井显示对象、层位显示对象、断层显示对象、岩性显示对象等,同一显示对象又对应有缩略图浏览的鸟瞰显示对象和目标区域显示的局部显示对象;数据对象在文档中的坐标,称之为文档坐标,数据对象在视图中对应着的显示对象的坐标,称之为视图坐标,视图坐标也称之为数据对象在视图中对应的屏幕显示坐标,文档坐标到视图坐标之间的转换称之为坐标系转换关系。 [0030] In this embodiment, the system has a document view of the three main window, respectively, and the view of the document associated therewith I 1, 2 and the document associated therewith views 2, 3 and the associated documentation with a view 3; wherein the seismic data, for example, lists a variety of different types of data contained in the target document I, such as profile data, well data, layer data, fault data, lithology data, and view 1 included in the display object associated with the data objects of different types, such as the cross-section display object, the display object well, the display object horizon, the fault display object, the display object other lithology, and the same display object corresponding to the bird's-eye viewing thumbnail the partial display area of ​​the display object and the target display object; object coordinate coordinate data in the document, the document is called the coordinate data corresponding to the object displayed in the view object, called the view coordinates, called also view coordinates data corresponding to an object in the view screen coordinate conversion between the document to coordinate the coordinate system referred to the view coordinate conversion relationship. 同一文档视图体系下,视图和文档通过坐标系转换关系相互关联,图1中,视图1和文档I通过坐标系转换关系I建立关联,视图2和文档2通过坐标系转换关系2建立关联,视图3和文档3通过坐标系转换关系3建立关联。 The same document view system, views, and documents through coordinate conversion relationship interrelated, in FIG. 1, the view 1 and the document I through coordinate conversion relationship I associated, view 2, and documents 2 through coordinate conversion relationship 2 associate view 3 by 3 and documentation coordinate conversion relationship 3 associate.

[0031] 对于同一个数据对象来说,文档坐标是一致和唯一的,本发明为实现大幅面图形图像缩略图浏览和目标区域的快速定位,对同一个数据对象的文档坐标建立小比例尺和大比例尺两套坐标转换关系,小比例尺坐标转换关系对应着缩略图浏览显示对象的视图坐标,控制视图的缩略图浏览,即鸟瞰显示对象,大比例尺坐标转换关系对应着目标区域显示对象的视图坐标,控制视图的目标区域显示,即局部显示对象。 [0031] For the same data objects, documents and coordinate consistent only, the present invention is to achieve large-format graphic image thumbnail view and quickly locate the target area, the establishment of small and large-scale document coordinates with a data object two scale coordinate transformation, small-scale coordinate transformation corresponding to coordinates of the view thumbnail view display object, control view thumbnails browsing, i.e. bird's-eye view display object, large scale coordinate transformation corresponding to coordinates of the view region display target object, the control view display target area, i.e. the partial display object. 建立小比例尺坐标转换关系的方法是首先确定在屏幕上能看到整幅缩略图的分辨率,在此分辨率的基础上,得到文档坐标与小比例尺的屏幕显示坐标的变换关系,建立大比例尺坐标转换关系的方法是首先确定能分辨出目标区域显示所需要的分辨率,在此分辨率的基础上,得到文档坐标与大比例尺的屏幕显示坐标的变换关系。 Method for establishing small-scale coordinate transformation is to first determine the on-screen thumbnails to see the whole resolution, on the basis of this resolution, to obtain documents and coordinate small-scale screen display coordinate transformation relationship, the establishment of large-scale the method of coordinate conversion relationship is to first determine the target area can distinguish the resolution required for display, on the basis of this resolution, and to give the document a large scale coordinate transformation between the coordinates of the display screen. 因此本发明实施例中,同一数据对象对应有两个显示对象:鸟瞰显示对象和局部显示对象,同一数据对象在不同的比例尺控制下,实现同一视图局部显示对象和鸟瞰显示对象各自独立的坐标映射和转换,局部显示对象和鸟瞰显示对象各自独立的显示;例如对于同一剖面数据,可以分别产生剖面局部显示对象及剖面鸟瞰显示对象,局部显示对象和鸟瞰显示对象对应着两套不同的比例尺,当比例尺确定了,则局部显示对象和鸟瞰显示对象就是独立的关系,它们的显示大小和位置只受它们各自的比例尺控制;再根据同一个数据对象的文档坐标得到的小比例尺视图坐标与大比例尺视图坐标的对应关系,则可实现鸟瞰显示对象对局部显示对象的定位,因为鸟瞰显示对象和局部显示对象都是对同一种文档数据的显示,当比例尺确定后,则鸟瞰显示对象的显示位置 Thus embodiments of the invention, the same data corresponding to two display target objects: a partial bird's-eye view display object and display object, the same data objects at different scale control, to achieve the same object and the bird's-eye view of a partial display the display object coordinate mapping each independently and conversion, partial bird's-eye view display object and display the display object independently; for example, the same cross-sectional data, the display object may be generated partial cross-sectional bird's-eye view display object and a cross-sectional, partial bird's-eye view display object and display object corresponding to two different sets of dimensions, respectively, when scale is determined, the partial display object and the bird's-eye view display object is independent relationship, their display size and position only by their respective scale control; then according to the small scale view coordinates obtained in the same document coordinates of a data object of large scale view coordinates corresponding relation, the locator object can be achieved bird's-eye view display to the partial display object, since the object and the bird's-eye view display to the partial display objects are displayed in the same document data, when the scale is determined, the bird's-eye view of a display position of the object 和大小通过不同比例尺转换对应着局部显示对象的显示位置和大小.这个关系的确定,则意味着鸟瞰显示对象对常规显示对象的定位。 Display position and size of the object corresponding to the size and the local scale by different conversion. This relationship is determined, it means that a conventional bird's-eye view display objects positioned on the display object. 为了实现局部显示对象和鸟瞰显示对象的无缝切换,在局部显示的情况下,此时大比例尺起着控制作用,则大比例尺显示对象显示,小比例尺显示对象隐藏,在对应着鸟瞰显示对象的情况下,则小比例尺显示对象显示,大比例尺显示对象隐藏。 To achieve the object and the bird's-eye view display partial display object seamless switching, in the case of the partial display, in which case the control plays a role in large scale, the display object display large scale, small scale display object is hidden, the display object corresponding to the bird's-eye view case, the small scale of the display object display, large-scale display object is hidden. 并且当文档数据的有任何改变时,同时对应着局部显示对象和鸟瞰显示对象的改变,实现了局部显示对象和鸟瞰显式对象的同步显示与更新。 And when there is any change in the document data, while the corresponding display object and partial bird's-eye view display object is changed, to achieve a partial bird's-eye and explicit display objects displayed in synchronization with the update object.

[0032] 不同文档视图体系的视图与视图之间的联系、同一视图里不同的显示对象之间的联系以及同一文档中不同的数据对象之间的联系均通过内存双向链表进行管理,本发明中,在主窗口中建立对不同文档视图体系的视图与视图之间的管理的视图内存双向链表,图1中,通过视图内存双向链表将视图1和视图2之间、视图2与视图3之间连接起来,因为要实现同步滚动,光标跟踪的功能,所以就需要实现任何一个视图能够很快的能找到另外一个视图指针的功能,视图内存双向链表能够很好的满足这个功能,视图内存双向链表具有分别指向一个视图和另外一个视图的前向指针和后向指针。 [0032] The link between the views and the views of different document view systems, the link between the links between the same view in different display objects in the same document as well as different data objects are managed by a doubly linked list of memory, the present invention , establishment of view of the doubly linked list of memory management between different documents views and views of the system in the main window, Fig. 1, between 1 and view 2 view through the doubly linked list of memory to view, and view 2 view 3 between connect, because to achieve synchronized scrolling, cursor tracking function, so you need to implement any view can quickly be able to find another view of the pointer function, view memory doubly linked list can well meet this function, view memory doubly linked list and having a forward pointers point to a rear view and a view of the further pointer. 同时,在视图中建立对同一视图里不同类型的显示对象之间的管理的显示对象内存双向链表;因为有的显示对象(例如层位,断层,井位)的显示依赖于地震剖面的显示,而且每一个显示对象都有对应的鸟瞰显示对象和局部显示对象,它们之间要互相切换显示,同时对应着显示对象的增加和删除,也需要有一个方便的管理机制,而内存双向链表比较好的满足这个功能,显示对象内存双向链表具有分别指向一个显示对象和另外一个显示对象的前向指针和后向指针,图1中,通过显示对象内存双向链表,将同一视图里不同的显示对象之间,如剖面局部显示对象与剖面鸟瞰显示对象之间、剖面鸟瞰显示对象与井局部显示对象之间、井局部显示对象与井鸟瞰显示对象之间、井鸟瞰显示对象与层位局部显示对象之间、层位局部显示对象与层位鸟瞰显示对象之间、 Meanwhile, the doubly linked list create display objects in memory management between the display objects of different types in the same view in the view; because some display object (e.g., horizons, faults, wells) are shown to be dependent on the seismic section of the display, and each display object has a corresponding bird's-eye view display objects and partial display objects, they appear to switch between each other, while the corresponding increase in display and delete objects, also need to have a mechanism to facilitate the management, and memory doubly linked list is better satisfies this function, the display object memory doubly linked list with objects and other display objects forward pointer and a backward pointer, in FIG. 1, the display object memory doubly linked list, the same view in different display objects point to a display of Room, such as a partial cross-sectional and cross-sectional bird's-eye view display object between display objects, and a cross-sectional bird's-eye view display object between partial display objects wells, wells partial display object among objects displayed Aerial wells, wells bird's-eye view display object and display object of a local horizon inter-layer position between the partial display target object and the bird's-eye view display horizon, 位鸟瞰显示对象与断层局部显示对象之间、断层局部显示对象与断层鸟瞰显示对象之间、断层鸟瞰显示对象与岩性局部显示对象之间、岩性局部显示对象与岩性鸟瞰显示对象之间连接起来。 Aerial bit partial display the tomographic display object among objects, a tomographic partial display object among objects displayed tomographic bird's-eye view, bird's-eye view display objects related to lithology tomographic partial display between the object, the display object lithology and lithologic partial bird's-eye view display between the object connect them. 并且,在文档中建立对同一文档中不同类型的数据对象之间的管理的数据对象内存双向链表,数据对象的内存双向链表的建立对应着显示对象的内存双向链表,图1中,同一文档不同类型的数据对象之间,如剖面数据与井数据之间、井数据与层位数据之间、层位数据与断层数据之间、断层数据与岩性数据之间,通过数据对象内存双向链表连接起来。 Further, the doubly linked list of memory objects to establish a data management between the different types of the same document data objects in the document, establishing a two-way linked list of memory data objects corresponding to the display object memory doubly linked list, in FIG. 1, different from the same document between types of data objects, such as between the cross-sectional data and well data, between the well layer and the data bits, data bits between the tomographic data layer, between tomographic data and lithologic data, via a data connection doubly linked list of memory objects stand up.
