Below in conjunction with embodiment, the present invention is described in detail.
Initial dip is measured scene and is used tree-like storage structured data.Whole scene is root node, by multiple scenario block
Node is constituted.Each child node, except having the triangular facet figure metaset of self, also comprises several higher precision grade scenario block
Child node.The most successively segmentation is gone down, until highest ranking child node.Scenario node accuracy class is the highest, and its details is the abundantest,
And areal extent is the least.During render scenes, the distance decision according to node to video camera (representing the observer in three-dimensional scenic) is
Render present node figure metaset and still render child node.
The inclination measurement scene Objects extraction method that the present invention provides, for the inclination measurement field of above tree-like storage structure
Scape data carry out atural object cutting lock out operation, see Fig. 1, comprise the following steps:
1) atural object profile is set
Atural object profile is the horizontal plane projection of atural object boundary line.Two ways can be used to set atural object profile, and one is manual
Choosing profile point, two is to load from file.
1, manual definition atural object profile
Can be by choosing intersecting point definition atural object profile in three-dimensional scenic one by one during first extraction atural object.All profile point
The polygon constituted should be simple polygon, there is not crossing situation between the most polygonal any two lines section.Profile point
Order is unified for counterclockwise.
Generally, the outline polygon of definition should surround the institute of atural object floor projection a little and the least, to ensure
Obtain complete and that border is correct atural object, but for reducing the amount of calculation of atural object and the spacing of electric wire in power circuit designs,
Improving and check speed, it is also possible to only choose the part that in atural object, distance line is nearer, this is to meet power circuit design reality
Situation.
2, existing outline data is used
The outline data of manual definition can be saved in file, loads from file and directly act on when needing to reuse
In inclination measurement scene.It is particularly well-suited to be replaced by original contextual data the situation of higher precision contextual data, eliminates weight
The troublesome operation of new manual definition atural object profile one by one.Outline data in file saves the information such as atural object ID, establishment time,
Order identical when should create with last time when again choosing atural object is carried out.
2) cutting triangle
Cutting triangle needs to carry out one by one intersecting judgement with all trianglees in scene by atural object contour line.
1, contour line and triangle cross poly-lines are calculated
For each triangle, first one 2 D vertex array object of definition, is used for storing contour line and triangle
The some broken lines intersected, one-dimensional representation broken line, the summit of each broken line of two-dimensional representation.Concrete execution step is such as
Under:
(1) vertical array, the broken line that this array representation contour line intersects are created with triangle.It is initial
Turn to sky.
(2) whether the initial profile point of judgement is in triangle, if then adding vertical array.
(3) judge whether to take all over all profile point (i.e. took last time is starting point, the most just can contain all sub-line sections),
It is current vertex array to be added to two-dimensional array (if not for sky), jumps to (8th) step；Otherwise carry out next
Step.
(4) next profile point is taken as current point.
(5) judge that current point and the line segment between the upper some limit whether with triangle is intersected.If intersecting, intersection point is added
Enter vertical array.
(6) judge that current point, whether in triangle, is to add vertical array, returns (3rd) step；Otherwise carry out next
Step.
(7) judge whether vertical array is empty, if not empty, add vertical array to two-dimensional array, then that it is clear
Empty.Return (3rd) step.
(8) if initial profile point is in triangle, then last vertical array and first vertical array are merged into
One broken line (noting: starting point respectively can occur once in the two vertical array, only should retain).
According to triangle comprises the number of profile point, triangle can be intersected with contour line and be divided into 3 kinds of situations, i.e. not have
Profile point in the triangles, has partial contour point in the triangles, and whole profile point the most in the triangles, see Fig. 2,3,4 left
Side figure.
2, triangulation
The summit of the some broken lines obtained with previous step on 3 summits of former triangle is configured to the triangulation network.Structure three
Angle net can use popular De Luonai Triangulation Method (Delaunaytriangulation).It should be noted that and to protect
Demonstrate,proving in the triangulation network that each broken line occurs in neotectonics as the limit of triangle, these broken lines can be divided into some
Section, but do not allow disappearance.Triangulation result, sees Fig. 2,3,4 right figure.
After triangle subdivision completes, former triangle is deleted from the scene triangulation network, add all of triangulation generation
New triangle.
These are only the situation processing a triangle, need to process successively other all triangles of current scene piecemeal
Shape.Expand other world subdivisions of current accuracy grade the most successively to, the inclination measurement contextual data of other accuracy classes.
Profile can be used during cutting to surround frame and quickly to reject means, without often with the world subdivision encirclement non-intersect conduct of frame
Individual triangle calculates the most in detail.
After cutting, the triangle edges in each triangulation diagram tuple overlaps with contour line, or contacts with contour line,
Or it is separated with contour line, and situation about intersecting with contour line will not occur.
3) atural object is separated
All triangular facets in current atural object profile are extracted, is stored as the packet of single atural object pel, and uses
The ID of atural object labels.Atural object lock out operation is only used for the 2nd) step carried out the node of triangulation, do not carried out three
The node of angle subdivision can directly be ignored.In former scenario node, the most newly-built single pel packet, with former scene pel
Packet is side by side.The packet of this pel is atural object pel packet in current scene node.
Each triangle in being grouped for scene pel, performs following operation.
1, triangle horizontal center point is calculated
The plane coordinates (XY) on Atria summit is separately summed again divided by 3, triangle center point coordinates
For
((x1+x2+x3)/3,(y1+y2+y3)/3)
2, judge that triangle is whether in atural object profile
Judge that above-mentioned triangle two-dimensional center point rudimentary algorithm whether in atural object profile is: constructing an initial point is three
Dihedral central point, and the ray that direction is (1,0).Calculate ray situation about intersecting with atural object outline polygon, whenever ray and
When a polygonal limit is intersected, just carry out changing the most from inside to outside or contrary conversion.Record is tracked through polygon
Through odd-times, the parity of shape number of times, illustrates that triangle center point is positioned at polygon, even-times explanation is positioned at outside polygon.
Practical Calculation also needs to consider the situation that polygonal limit is overlapping with ray.According to aforementioned cutting result, do not exist and profile
Line cross point triangle, if therefore triangle center point is in contour line, then triangle is in atural object profile.
3, atural object pel is separated
If current triangle is in outline polygon, then it is removed from scene graph tuple, and join current position
In the packet of thing pel.If not in outline polygon, then ignore.
Process the every other triangle of current scene node successively.A scenario node original after having processed divides
It is a scene packet and multiple atural objects packet (being belonging respectively to multiple atural object).Atural object pel packet atural object ID labelling, and can
So that pel extraction can be carried out by atural object ID or to arrange the operations such as color.
Process other scenario nodes of present level successively.Same atural object may multiple by multiple scenario nodes
Thing packet composition.Need should obtain when extracting data the combination of all these data.
Process the inclination measurement contextual data of other grades successively.Node diagram metadata after atural object separates can save as
The node file of format, is loaded directly into the node file of format after processing later, and need not root the most again
According to atural object profile cut separation ancestor node data, thus improve processing speed.
Above-mentioned 2) 3) strategy that step operation scenario node uses is first (to take depth-first or range excellent all nodes
First search strategy) perform operating procedure 2), more all nodes are performed operating procedure 3).This mode needs to travel through twice tree
Structure, and the intermediate object program of for the first time operation needs to be retained in internal memory or keeps in file for step 3), execution
Inefficient.Can use another kind of processing mode in practical operation, the most only tree construction of traversal, saves for each scene
Point, first carries out step 2), and then perform step 3), so can save the expense of temporary a large amount of intermediate object program, improve and hold
Line efficiency.
4) atural object operation
Atural object operation mainly includes that obtaining the ground object model such as line map metadata, distance calculating, ray collision detection is correlated with
Operation, and the interpolation of terrain object attribute information and search operaqtion.
1, primitive information is obtained
Need to use the primitive information of atural object in some cases, as ground object model exported as the file of specified format for not
Program use etc..From three-dimensional scenic, obtain line map metamessage need to specify atural object ID and the accuracy class of model.From
Root node starts to inquire about step by step, until arriving the node of given level.If node diagram metadata does not loads, then from corresponding node
File loads.Obtain the figure tuple specified according to ID, be packaged as the form needed, return to father node.Father node is by each height
Node return same atural object different meta graph recognition and be a figure tuple, return to the father node of oneself.The most step by step
Upwards, eventually arrive at root node, be reassembled into an overall diagram tuple at root node and return to caller.For commonly used
Atural object pel grade, can be saved in single file, when needing directly from file read, without traversal whole
Scene.
2, ray collision detection
Three-dimensional circuits design it is frequently necessary to choose atural object to perform other operations with mouse.First by 3-D graphic window
In click position be converted to the ray in three dimensions, then calculate the intersection point of ray and each atural object, collision distance (is penetrated
Line starting point is to the distance between ray and the atural object point of impingement) the shortest atural object is selected atural object.
(1) to the incoming parameters of scene root node, including input parameter ray, output parameter atural object ID, collision distance
(being initialized as infinity), the point of impingement.
(2) root node travels through each child node, and each node performs collision detection operation.
(3) for present node, it is first determined whether visible, invisible, ignore；Visible, carry out next step.
(4) using node to surround ball and carry out collision detection with ray, if collided unsuccessfully, or collision distance is more than the most defeated
Go out collision distance, then ignore present node.Encirclement ball detection is used can quickly to reject some nodes.Collide under the most then carrying out
One step.
(5) judge present node be whether can rendering node (having loaded figure tuple), perform ray the most successively with current
Collision detection between each pel of node.For each pel, if current collision distance is less than output collision distance, the most defeated
Going out collision distance and be updated to current collision distance, output collision atural object ID is updated to current atural object ID, and the output point of impingement is updated to
The current point of impingement.Father node is returned after being finished；If present node be can not rendering node, traversal present node all sons
Node, recurrence performs (3)～(5).
(6) after all node traverses complete, finally return that parameter be by the atural object ID in point and the point of impingement, collision away from
From；If it is empty for returning atural object ID, then it represents that unselected any atural object.
3, distance calculates
Importing the main purpose of atural object in power circuit design is the distance calculating electric lines of force etc. between electrical body and atural object,
And make comparisons to differentiate that current design is the most reasonable with the safe distance in design specification.It is high owing to electrically checking precision prescribed,
Therefore the full accuracy pel that should use atural object calculates.The present invention uses following steps to calculate electric wire (or other objects) and ground
The distance of thing.
(1) to the incoming parameters of scene root node, including input parameter electric power line chart metaset, atural object ID, output parameter
Electric lines of force is to atural object minimum range point on (being initialized as infinity), electric lines of force, the minimum range point on atural object.
(2) root node travels through each child node, each node is performed distance and calculates operation.
(3) for current node, first detecting whether to comprise the figure tuple specifying atural object ID, if not comprising, then ignoring
Present node, returns to father node；If comprising, perform next step.
(4) calculate input primitive collection and surround ball and present node encirclement ball distance, if more than output distance, then ignore current
Node, returns to father node.Use encirclement ball distance can quickly reject some nodes, improve arithmetic speed.If surrounding ball distance
Less than output distance, then perform next step.
(5) traversal present node child node, performs (3rd) (4) step operation, until arriving full accuracy child node.
(6) if full accuracy child node can not render, then pel is loaded from file；Otherwise, next step is performed
(7) calculate present node and specify the distance of the ID each triangle primitives of figure tuple and each pel of input primitive collection.
If this distance is less than output distance, then update current distance, and two minimum range points.Return results to father node.
(8), after all node traverses complete, the parameter finally returned by root node is by the atural object in point and collision
Point, collision distance.
4, adeditive attribute information
