Represent in equipment virtual machine mode at user side, carry out initialization and the loading of equipment in the mode of carry in the POOL of equipment pond, user side is namely dynamic after proposing device request creates a newly connection in equipment POOL, complete the initialization of virtual unit information and the loading of associated traffic data simultaneously, after user operation uses this equipment, discharge this immediately connect and reclaim relevant resource, equipment Foundations storehouse realizes the storage of basic data of all hardware equipment, the network equipment, carries out form definition and the persistence of hardware data with the form of XML file or DB.

Modeling tool is adopted to complete the generation of three-dimensional scenic, working environment information is utilized to set up model of place database, the fundamental node of model of place database comprises group node, object node, face node and some node, utilize node by all models in whole scene logically structure organization be inverted level tree structure.

After Modling model database, initialization realizes the d engine calling, show and control to model, comprising: arrange three-dimensional picture pixel format, determines the figure place of each impact damper; Initialization passage viewport size, the parameters of illumination model, background color, eye coordinates; Create frame buffer and title is set; Create camera, passage and illumination model, to illumination model assignment; Create scene, illumination model is added scene, determines camera position, and camera is connected with scene; For passage assignment determination size, erasing look, and by scene and camera and expanding channels; Passage is added frame buffer.After initial work completes, dynamic importing three-dimensional model, then an object callback function is set for each object (i.e. three-dimensional model), concrete control routine is write in call back function, the drafting of each frame animation is realized by call back function, when object discharges, call back function also terminates immediately.

Interactive controlling process comprises collision detection, three-dimensional body motion control, three dimensional object pickup.

So-called collision, is exactly in the several objects at a time, in space, there is the space occupied between one or more pairs of object and be in the critical point overlapped.In reciprocal process, in order to the authenticity simulated, multiple method must be adopted to be limited the object of which movement in the interbehavior of user and virtual world.Collision detection is a kind of conventional method, and the mistake as appearance can be avoided through walls to the collision detection of buildings, can avoid the generation of object fusion phenomenon, thus reach the true effect in real world to the collision detection of mobile object.Collision detection is the interactive basis in virtual reality between dynamic object and stationary body or between dynamic object and dynamic object.

Translation, rotation, convergent-divergent are the most basic motor patterns, and in interactive controlling, the operation carried out entity and viewpoint can be converted into the combination of the geometric transformations such as translation, rotation and convergent-divergent.By the geometric transformation of object in three dimensions, Fast transforms can be carried out to object, thus obtain the Dynamic Announce effect of object in reciprocal process.

Three dimensional object hit detect function can be picked up by object names, also can be realized by the collision checking method of X-ray detection X, as follows by the collision checking method of X-ray detection X: according to the matrix used in virtual environment inverse transformation is done to projection ray and and model carry out test for intersection and pick up object.Its process clicks somewhere with mouse on screen, obtain the screen coordinate of mouse clicking point, the coordinate of subpoint is obtained again by vision area conversion, so obtain one to be starting point with viewpoint and through the ray of subpoint, if crossing with certain model in scene after this ray being done projective transformation, viewing transformation, then represent that pickup is to this model.

Encircle sphere is defined as the smallest sphere comprising object.The maximal value of object vertex coordinate and the average of minimum value can be used for determining the centre of sphere of encircle sphere.For two encircle sphere, if centre of sphere distance is less than two radius of a ball sums, then two encircle sphere intersect.Utilize spheroid to build the level encircle sphere tree of object, the detection between node and node can be carried out, but its compactedness of surrounding object is inadequate fastly, the intersection testing between the encircle sphere that can there is bulk redundancy.

Axial bounding box (AABB) be defined as each bar limit be all parallel to coordinate axis and comprise this object minimum side's rectangular parallelepiped.Calculate the AABB bounding box that the minimum value of x, y, z coordinate on summit in all geometric elements of composition object and maximal value just can determine object.Test for intersection between AABB bounding box is also fairly simple, and when all intersecting when between the projection in zone of two AABB bounding boxs in three coordinate axis, they are just crossing.According to this characteristic, three-dimensional can be asked friendship abbreviation to turn to one dimension and ask friendship problem.Hand over, as long as the test for intersection therefore between AABB does 6 comparison operations at most because two articles AABB bounding box intersects the homogeneous phase that must project in three coordinate axis.AABB bounding box calculates simple, but compactedness is poor.As shown in Figure 2, suppose there is two AABB bounding box A and B, the central point of A and B is respectively C _aand C _b, X-axis is projection coordinate's axle, some C _aand C _bprojection in X-axis is respectively P _aand P _b.The half of the projected length of bounding box A and B in X-axis is respectively R _aand R _b.If C _ac _b≤ P _ap _b, then in X-axis, A and B is non-intersect, otherwise A and B intersects in X-axis.

Different due to geometric object in scene, there will be distinct effect when different object carrys out approximate simulation with different bounding boxs, unreasonable use bounding box can make collision detection efficiency significantly reduce.Such as, if a spheroid AABB simulates, there will be larger error, and a strip object encircle sphere is simulated, the precision of collision detection also can be very poor.

Alternatively, in collision detection of the present utility model, shape according to different object uses different bounding box approximate simulations to different object, namely the object that encircle sphere analog approximation is spherical is used, all the other objects adopt AABB bounding box to carry out analog approximation, first encircle sphere and the projection of AABB bounding box are sorted and divided into groups, the object pair that rapid eliminating can not collide, then test for intersection is carried out to the potential collision detection collection in each group, now collision detection is converted into the test for intersection of encircle sphere and encircle sphere, test for intersection between the test for intersection of encircle sphere and AABB bounding box and AABB bounding box, finally carry out collision detection of high precision.

As shown in Figure 2, use heapsort method to the projection access order on a certain axle, and fix dividing the sub-section boundary of rear projection for the first time, projection subsegment is referred to as " group ", and after being upgraded by Moving Objects afterwards, the projection value of bounding box compares with the boundary value of bounding box place group before, if still within border, then continue to stay in this group, otherwise the boundary value organized with next compares, the like, until find new ownership group; Then sort in real time to projection value often organizing interior use heapsort method, getting rid of fast does not have overlapping object pair; Finally, to overlapping object to carrying out test for intersection, wherein has one at least to liking dynamically, as long as compare with this group and adjacent sets during bounding box grouping, and test for intersection only carries out in the group having dynamic object to exist, and which greatly enhances the efficiency of detection.This algorithm should be noted that following problem: (1) has entered the new projection subsegment of people when a part for a certain bounding box, and another part is when still staying former projection subsegment (as shown in dotted box in Fig. 2), bounding box is organized and is all needed to participate in collision detection belonging to two projection subsegments.In addition, two parts are all divided into, when carrying out test for intersection to x-axis corresponding to two object left-hand component and y-axis sublist when certain two intersected object divides the stage in coordinate axis, know that two objects are overlapping, algorithm just no longer carries out test for intersection to the projection of the right-hand component of two objects, thus reduces the execution time of algorithm; (2) if there is the very large object of volume in scene, first object must be decomposed into the sub-block of small volume before performing collision detection, more each sub-block is carried out crash tests respectively.

Wherein, the test for intersection of encircle sphere and AABB bounding box is as follows:

If the coordinate of point is (x, y, z) in AABB bounding box, the length of side of bounding box is H, and the centre coordinate of bounding box is (X _b, Y _b, Z _b), suppose that central point is positioned at true origin, then the equation of constraint of AABB bounding box is

{(x,y,z)|0＜x,y,z＜H}

Equally, if the coordinate of point is (x, y, z) in encircle sphere, the radius of encircle sphere is R _s, sphere centre coordinate is (X ₀, Y ₀, Z ₀), then the equation of constraint of encircle sphere is

$\left\{(x,y,z)\right|{\left({x-X}_0\right)}^2+{\left({y-Y}_0\right)}^2+{\left({z-Z}_0\right)}^2<R_S^2\}$

Suppose that AABB bounding box is positioned at true origin (0,0,0), order wherein X ₀non-vanishing, then the distance between AABB bounding box and encircle sphere is

If the angle of the line of AABB bounding box and encircle sphere central point and Z coordinate axis is θ, then have: work as Y ₀>0 and X ₀during >0, work as Y ₀>0 and X ₀during <0, work as Y ₀<0 and X ₀during >0, work as Y ₀<0 and X ₀during <0,

Only need to compare θ × dist and | Z ₀| the crossing situation of two bounding boxs can be obtained, if θ × dist is < | Z ₀|, then AABB bounding box is crossing with encircle sphere, otherwise non-intersect.

Collision detection of high precision comprises two stages, the collision detection of high precision process of first stage is as follows: polygon is projected to XOY plane, obtain a plane polygon, if polygon intersects, straight line must be had simultaneously all crossing with two polygons, around this principle, two parallel axis are done based on two central point subpoints, if intersected, must occur between two axis, specification error value ρ, n bar mean line is done, if existence m article of mean line and wherein two polygons intersect at point (X between the axis that two are parallel to y-axis ₁, Y ₁) and point (X ₂, Y ₂), wherein n, m are natural number and m is less than or equal to n, if | Y ₁-Y ₂| < ρ, then collide, and enters the collision detection of high precision of subordinate phase, the collision detection of high precision namely between element figure.

Crossing detection between element figure is the final tache of collision detection, element figure is triangle or tetrahedron, when element figure is tetrahedron, because tetrahedron is made up of four triangles, be leg-of-mutton test for intersection by tetrahedral test for intersection abbreviation, collision detection of high precision then between element figure is in fact the crossing detection between triangle, the test for intersection flow process between triangle as shown in Figure 4, if two, space triangle is respectively T1 (V ₀, V ₁, V ₂) and T2 (U ₀, U ₁, U ₂), then the test for intersection process between triangle and triangle is as follows:

S1: calculate the plane equation N1 at triangle T 1 place and the plane equation N2 at triangle T 2 place respectively;

S2: three summits calculating triangle T 1 respectively to three summits of the distance dv0 of plane N 2, dvl, dv2 and triangle T 2 to the distance du0 of plane N 1, dul, du2;

S3: if V ₀, V ₁, V ₂three points are all positioned at the same side of N2, and so triangle T I and T2 is non-intersect, or U ₀, U ₁, U ₂three points are all positioned at the same side of N1, and triangle T 1 and T2 are also non-intersect;

S4: if dv0*dvl=0 and dv0*dv2=0 sets up or du0*dul=0 and du0*du2=0 sets up simultaneously simultaneously, then triangle n and T2 is coplanar, forwards in plane and goes in two leg-of-mutton test for intersection subprocess;

S5: if there is one to be 0 in dv0, dv1, dv2, and two other symbol is identical, then a summit must be had in triangle T 1 to be positioned at triangle T 2 institute in the plane, and now problem is converted into a point and leg-of-mutton relation in Judge plane.If fruit dot is in triangle T 2 or on limit, so triangle T l and T2 intersects, otherwise non-intersect;

S6: if there are two to be 0 in dv0, dvl, dv2, then triangle T l must have a limit to be positioned in the plane of triangle T 2, and now problem is converted into the relation in Judge plane between a line segment and a triangle;

S7: removing several situation above, triangle T l and triangle T 2 place Plane intersects, try to achieve crossing line segment, now problem change into Judge plane middle conductor whether with triangle intersect.
