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.

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.

It is arbitrary and comprise the minimum rectangular parallelepiped of this object that oriented bounding box (OBB) is defined as direction.Due to the arbitrariness in its bounding box direction, although improve the compactedness of bounding box, this also increases the complicacy of its test for intersection.The test for intersection key of OBB is to determine that optimal direction is to build minimum bounding box.Test for intersection between OBB is theoretical based on release shaft.If non-intersect between two OBB projection in zone on certain axis, then this axle is called release shaft.Judge that these two OBB are non-intersect, only need draw to there is a release shaft between two OBB.Calculating the test for intersection of OBB needs 6 coordinate axis of storage two OBB to 9 vectors, 15 release shafts altogether obtained with 3 axis and another 3 axial multiplication crosses.Successively on these release shafts, whether intersect between the projection in zone of inspection two OBB.Judge two OBB intersect namely judge between their projection in zone on 15 directions whether all crossing, as long as judge whether two OBB intersect to do 15 comparison operations at most.

Alternatively, in collision detection of the present invention, first for object sets up Hybrid bounding box binary tree, described Hybrid bounding box binary tree is designed to 2 Rotating fields, its top layer adopts AABB, remainder layer all adopts OBB, the simple AABB of top layer gets rid of the object pair that can not collide fast, the OBB of lower floor accurately tests the object pair that may collide further, the AABB-OBB bounding box binary tree of geometric object Object as shown in Figure 2, the real time collision detection stage, the method of Task Tree is adopted to realize synchronous depth-first traversal to 2 bounding volume hierarchy (BVH) trees, can executed in parallel between the same layer subtask of Task Tree, the test for intersection between AABB-AABB and OBB-OBB 2 kinds of similar bounding boxs is carried out in ergodic process.

Adopt top-down method construct Hybrid bounding box binary tree, its core concept sets up the bounding box of geometric object, utilize splitting plane that geometric object is divided into 2 disjoint subsets respectively as new root node also for they set up bounding box, to new root node Further Division, until each child node is basic geometric graphic element, concrete construction process is as follows:

S1: be root node structure AABB, using geometric object as root node, obtain the AABB bounding box of geometric object according to the coordinate figure of its basic geometric graphic element comprised;

S2: determine to divide axle, judge whether the element that this node comprises is element figure, constructs OBB bounding box as leaf node for it if then direct, otherwise chooses most major axis as release shaft;

S3: with median method determination split point, with the face vertical through split point and with dividing axle for splitting plane, is divided into 2 disjoint subsets by all elements of this node;

S4: 2 subsets respectively as root node, for they build OBB bounding box, return S2, recurrence performs, until all element figures all become leaf node, forms a Hybrid bounding box balanced binary tree.

Wherein, the concrete steps building OBB bounding box are as follows:

S1: set triangle to integrate three summit vectors of i-th triangle surface as x ⁱ, y ⁱ, z ⁱ, n is the tri patch number of bounding box, and μ is the average of summit distribution, then μ is

$\mathrm{\μ}=\frac{1}{3n}\underset{i=0}{\overset{n}{\mathrm{\Σ}}}(x^i+y^i+z^i)$

S2: the average μ distributed by the summit of above formula can draw covariance matrix C

$C_{\mathrm{jk}}=\frac{1}{3n}\underset{i=1}{\overset{n}{\mathrm{\Σ}}}(\stackrel{\‾}{x_j^i{x}_k^i}+\stackrel{\‾}{y_j^i{y}_k^i}+\stackrel{\‾}{z_j^i{z}_k^i})(1\≤j,k\≤3)$

Wherein, $\stackrel{\‾}{x_j^i}=x_j^i-\mathrm{\μ},\stackrel{\‾}{y_j^i}=y_j^i-\mathrm{\μ},\stackrel{\‾}{z_j^i}=z_j^i-\mathrm{\μ},$ C _jkit is the element in the covariance matrix of 3 × 3;

S3: the proper vector obtaining matrix, determines three axis of OBB bounding box local coordinate.Because C is symmetric matrix, its proper vector is mutually vertical, after unitization for three proper vectors, sets their three axis (d as the local coordinate of OBB bounding box ₀, d ₁, d ₂);

S4: by all for tri patch summits respectively to three axis (d ₀, d ₁, d ₂) projection, three minimax projector distance differences are axially the size of OBB bounding box

u ⁰＝max(Project(d ⁰,v ⁱ))

u ¹＝max(Project(d ¹,v ⁱ))

u ²＝max(Project(d ²,v ⁱ))

w ⁰＝min(Project(d ⁰,v ⁱ))

w ¹＝min(Project(d1,v ⁱ))

w ²＝min(Project(d ²,v ⁱ))

S5: the center centre calculating OBB bounding box

$\mathrm{centre}=\frac{1}{2}(u^0+w^0)d^0+\frac{1}{2}(u^1+w^1)d^1+\frac{1}{2}(u^2+w^2)d^2$

S6: by all for object fixed point projections in three axial directions, calculate maximal value in three axial directions and minimum value, determine the size of OBB.

Wherein, the method of Task Tree comprises, the collision detection of 2 objects is realized by the bounding box binary tree traveling through these 2 objects simultaneously, be a Task Tree by the procedure definition of traversal 2 bounding volumetree, task is the collision detection in 2 object bounding volumetree between 2 nodes, the substance traversal of Task Tree can realize 2 synchronous depth-first traversal of bounding volumetree, between the subtask number of Task Tree be or relation, as long as detect crossing in the tree of one of them subtask, then 2 objects must collide, if travel through complete Task Tree also not occur intersecting, then can judge that 2 objects do not collide.Each is separate between task, and the subtask therefore on each level can executed in parallel.The collision detection Task Tree of A, B2 object as shown in Figure 3, a and b is the root node of 2 bounding box binary trees to be detected, a->left and a->right represents 2, the left and right child node of root node a, b->left and b->right represents 2, the left and right child node of root node b.

First carry out test for intersection between top layer root node AABB bounding box, if AABB bounding box intersects, then carry out the OBB bounding box test for intersection between next level of child nodes, the traversal method of Task Tree is as follows:

S1:2 root node a and b carries out collision detection, and the AABB bounding box of 2 root nodes detects, if the AABB of 2 nodes is non-intersect, can judges not collide between 2 objects, otherwise enter S2;

S2: if a and b is non-leaf nodes, then enter the collision detection that S3 carries out a->left and b->left, a->left and b->right, a->right and b->left, a->right and b->right; If a is leaf node, b is non-leaf nodes, then enter the collision detection that S3 carries out a and b->left, a and b->right; If a is non-leaf nodes, b is leaf node, then enter the collision detection that S3 carries out a->left and b, a->right and b; If a and b is leaf node, then carry out collision detection of high precision, return collision result;

S3:2 node carries out OBB test for intersection, if non-intersect, then can judge that 2 objects do not collide at these 2 nodes, otherwise return S2.

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 described 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.
