A. Integrated Technical Architecture
The realization of virtual reality technology is a foundation for 3D film and television animation designs [17].The essence of 3D animation is a sense of stereo vision generated by the continuous projection of graphics and images.Experiments can transform the imagination in their minds into 3D animation models and realize model creation and visual optimization through the 3D modeling software platform.Virtual reality technology is gradually extended and developed based on three-dimensional animation technology.Its advanced scene reconstruction ability initially needs three-dimensional models to build.The prerequisite for the final realization of virtual reality space scenes is the adaptive transformation ability of three-dimensional images.Experiments can conduct interactive feedback of virtual reality scenes by upgrading 3D animation technology.Therefore, virtual reality technology and 3D animation technology come from a school of thought design [18].After the development of 3D animation technology, it is called virtual reality technology.However, the interactivity of 3D animation technology stays in the passive information acceptance of the experimenter.The interactivity of virtual reality technology can make the system cooperate and deepen the scene according to the behavior logic of the experimenter and convey the space scene simulated by computer data artistically.3D animation technology is the fundament of producing virtual reality technology data.Here, the technical architecture for integrating virtual reality technology and 3D film animation has been designed and shown in Fig. 1 The integration technology of virtual reality technology and 3D film and television animation design gets 3D animation pictures of virtual reality through virtual environment construction, multi-dimensional audio-visual presentation, biological simulation, and 3D animation modeling, and then connects 3D animation editing design, biological data information collection, 3D model data storage and information data feedback processing through computer I/O interface, realize the integration of virtual reality technology and 3D film and television animation according to 3D animation design scheme and virtual reality external equipment.www.ijacsa.thesai.org

B. Manual Modeling Method of Animation Scene Based on 3Ds Max
The first step of basic 3D animation production is 3D scene modeling, and a 3D model scene is the golden key to open animation production.As a model designer, it is necessary to determine various modeling data of 3D scenes.For some indoor scenes with small space areas, it is relatively easy to obtain basic measurement data.Obtaining more reliable scene data is impossible for virtual scenes with large space and unlimited space.Now, it is essential to collect virtualization information data according to the previously simulated spatial scene data samples [19], reconstruct the scene model with the help of powerful computer data model processing ability, and complete this spatial scene modeling work with the highest efficiency through this virtual scene simulation method.This method enlarges and outputs the scene information through virtual reality, efficiently completes the reconstruction of a 3D model scene, and improves the accuracy of scene model data through virtual reality assistance to create a more realistic virtual world.

1) Construction of 3D film and television animation scene model:
This section will introduce the processes of producing complex 3D film and television animation scene models in 3Ds Max [20] and final 3D film and television animation scene models.The technical process of 3D animation 3D Max model construction is illustrated in Fig. 2. The production of 3D film and television animation scenes is the most difficult part of 3D software.The concept of time dimension is added in the production process, and almost any object or parameter can be animated in 3Ds Max [21].Import the designed virtual scene base map or real image scene base map into the 3Ds Max software, and export the shape format file through 3Ds Max.Based on the cut file, you can quickly create 3D film and television animation scenes using rule files, export 3D film and television animation scenes and convert the model format, convert the shape format file into 3D Tiles method, select the elevation to generate 3D film and television animation scene, use the pull white mold method, process the shape format file through C # tool and output the code, and then program the code, animation scene model and format converted animation scene model in the Cesium framework to achieve 3D animation 3Ds Max model construction.

2) Realization of 3D film and television animation scene;
After the 3Ds Max model is established, 3D Exploration, Wcvt2pov, and other software can convert the 3Ds Max model into the corresponding OpenGL C C++ format file, or the program can directly load the 3Ds Max model.The software format conversion method can preserve the model's color, texture, and other information [22].However, some limitations are that software support and manual interaction are required for model transformation, and only one model can be transformed at a time.Therefore, the efficiency could be higher.The method of program direct loading can freely control the model to be loaded and promote the efficacy of program operation.After the 3DS model is loaded into the OpenGL program, the corresponding scaling, rotation, movement, and other controls are also required.The detailed process is as follows: a) Read 3Ds Max models.3Ds Max files are organized in a block structure, and there is a nesting relationship between blocks.Therefore, the 3D model data in the 3Ds Max file is read from a block in the model file, and the functional information of the block is judged according to the block ID, and then the corresponding processing is performed according to the block ID.A sub-block is read in the block processing process, such as the main editing block; block information is judged, and the corresponding data is extracted and stored.
b) Build model display list.When writing OpenGL programs, if you encounter repeated work, you can create a display list, load the repeated work, and call the display list where necessary.There are generally four steps to using the display list: assigning the display list number, creating the display list, calling the display list, and destroying the display list.
c) Minimum and maximum according to 3Ds Max model , the coordinates and the actual required width and height of the 3D scene are used to calculate their scaling ratio and scale the model.The functions used are: . Multiply the current matrix by a matrix indicating the scaled object., and refer to the scaling in corresponding directions, respectively.
d) Rotate the model according to the direction angle of the model in the 3D film and television animation scene.The functions used are: . Multiply the current matrix by a matrix indicating a rotating object.The f) Realize the placement of 3Ds Max models in the 3D scene according to the corresponding size, direction, and position, call the display list, and complete the drawing of 3D movie animation scene models.

C. Texture Mapping Processing
After the establishment of 3D film and television animation scene models, to make the scene more realistic, it is necessary to conduct texture mapping processing on it.Before texture mapping, select the contour of a 3D film and television animation scene [23].Here, a cubic uniform B-spline curve extracts the contour of 3D film and television animation scenes.The expression formula of the curve parameter equation is as follows: In the above formula, represent cubic uniform Bspline curve equation; and are parameters; , , all are cubic B-spline basis functions.
The cubic uniform B-spline curve and expression formula are as follows: In Eq. ( 2), represents the th sum of three cubic uniform B-spline curves; represents the total number of cubic uniform B-spline curves.
After the contour line is drawn, rotate the selected rotational axis to build the model [24].The right-hand coordinate system is used in texture mapping, the positive direction of the shaft is to the right and the positive direction of the axis is upward, so the rotation axis is selected as shaft.Therefore, the parametric equation of the surface after rotation is: For the gridding of 3D film and television animation scene models, the unit length of the grid will be intercepted according to the curvature of each point of the drawn contour line, and the grid will be further subdivided where the curvature is large.The curvature solution formula is as follows: In the above formula indicates the arc length parameter; represents a non-arc length parameter; ̈ means right perform a second derivative.
After the above steps, the mesh of the 3D movie and television animation scene model is more reasonable, and the resulting mesh quadrilateral tends to be the non-planar area of the original model, which is more conducive to rendering in the texture mapping phase.
Texture mapping technology can simulate the fine and irregular color texture on the surface of people (objects).The texture mapping technology can cover any planar figure (image) on the 3D animation model's surface [25] so that the model surface can produce a more realistic color texture, enhance the authenticity of 3D animation, and facilitate the modeling processes.There are two steps in texture mapping technology.The first step is to determine the texture attribute, determining which part of the person (object) surface parameters must be set as the texture shape.The second step is to create a mapping relation between the texture space and the person (object) space and a mapping relation between the person (object) space and the screen space.Fig. 3 shows the mapping definition.m: Character (object) space Texture space T: Screen space Character (object) space p q p (u，v) T(q)=P m(P)=(u,v) Just basic contour characteristics, i.e., lack of surface texture details, can decrease the realism.It needs to map each module's texture to raise the model's realism.
The general direction of the surface patch specifies which space plane the surface patch projects to and projects to the plane with the smallest angle between the whole direction of the surface patch and the plane.As some parts of the person (object) surface are curved, it is necessary to calculate the overall direction of the curved surface.The computation method can be summarized as follows: Assume that , , are three vertices of a triangular patch and cross product [ ] [ ] is perpendicular to the patch and normalized to get the normal vector of the triangular patch the average vector sum of the module can be obtained by averaging the sum of all patch normal vectors, and then the general direction of the module can be obtained.The equation is as follows: Where, indicates the total number of vertices.
To study the mapping relation between the surface patch and its related texture coordinates, the texture coordinates of www.ijacsa.thesai.org the grid points is computed through the perspective projection transformation, and the formula is as follows: (6) In which belongs to an unknown parameter, and is the texture coordinate, the corresponding homogeneous texture coordinate is , grid point space homogeneous coordinate is , the perspective projection matrix of is and the constant coefficient is .Based on the Eq. ( 5) and Eq. ( 6), two independent linear equations exist for each group of corresponding mesh and texture vertices.To transform the matrix , selecting three sets of feature points is necessary.
Analyzing all texture mapping processes, and setting the texture image size to simplify Eq. ( 7), and the process is as follows: where, and is an unknown parameter, is the surface vertex coordinate.
For Eq. ( 8), only a set of characteristic points can be used to calculate the unknown parameters.When extracting textures, all textures are made into the smallest bounding box.There are many tangent points at the edge of the image [26], which is very easy to get a group of feature points.Set texture coordinates and surface vertex coordinates is a group of characteristic points, which can be obtained by substituting into Eq.( 8): After the above steps, the texture mapping of the 3D movie animation scene model is completed.

D. Character Modeling of 3D Film and Television Animation
According to the 3D animation character model and action library, users should just choose their required role prototype, modify the parameters like the height and body proportion of the role prototype, and get the 3D animation target character.The 3D animation target character matches the prototype 3D animation character's skeleton, mask, controller, and original actions in the action library.Fig. 4 is the composition diagram of the 3D animation character.Components of a 3D animation character template include a virtual skeleton, skin, and controller, and it is a prototype for 3D animation.A set of basic actions allocated for 3D animation character prototypes is the 3D animation character action library.Users can freely modify the proportions and shapes of 3D animation characters based on the graphical interface, design the 3D animation character they want, or create new 3D animation characters.

E. 3D Animation Character Simulation
Motion capture technology is used to store many motion instances of character motion in the concerned motion library.The attained motion instances are represented in 3D form through virtual artificial synthesis software so that the 3D animation system is visual and convenient to change the action of the character model.The Newtonian Euler motion model is used to verify whether the new action studied is reasonable.The character action is set as motion (t) by the 3D animation system, and the character's original pose (ti) is changed to gain a new character pose (ti).These operations lead to visual interactive action design.The user window is in size.By moving the character model with the mouse, the variation in direction will be and the change in direction will be .According to Euler's theorem, for as representatives of , and , the relationship of direction rotation after reasoning is as follows:

F. 3D Animation Model Optimization Method based on Improved Quadratic Error Measure Algorithm
The edge collapse algorithm, also known as the Quadric Error Metric (QEM) algorithm, is not only fast in running speed, low in memory consumption, and simple in calculation but also has a very high overall similarity between the simplified mesh and the model.This paper improves the original quadratic error measure algorithm (QEM) and uses the improved QEM algorithm to optimize the scene modeling.
The specific steps are as follows: 1) Read in the original mesh data, which contains the vertex coordinates in the mesh and the vertex, sequence and other data information of the connected triangular patch.
2) Find the discrete curvature of each vertex in the mesh the area of the local area is obtained from the formula , and compare the two weighting factors with the matrix weighting to obtain the quadratic error matrix of each vertex in the network : (11) where, include vertices for Gaussian curvature of the edge of , is Gaussian curvature of a vertex .
The expression of is: where, is an adjacency angle of vertex ; is the number of triangles associated with vertex ; ∑ is a vertex the sum of adjacent triangular mesh areas, that is the local area.
3) The appropriate threshold through which the input is low , determines whether it is a boundary.If it is a boundary, set .4) Get the quadratic error matrix of each vertex according to step 2 .To calculate the shrinkage cost of each edge , if ̃ the shrink cost is put on the stack, the higher the value of , the more backward it is in the stack, and on the contrary, the more forward it is.5) Take the edge with the lowest shrink cost from the stack to perform the shrink operation, that is, the top of the stack.Simultaneously, update the data structure of the network, calculate the new edge collapse cost, and update the stack sequence.
6) If the ideal simplification requirements are met, the algorithm ends; otherwise, the above process continues until the simplification requirements are met.
After the above steps, the optimization of the 3D animation model is realized, and the resulting film and television animation screen is more fluent, and the structure is more reasonable.

G. Interaction Mode of 3D Film and Television Animation Scene based on Unity3D
Unity3D software is designed with the interaction mode of 3D film and television animation scenes based on the improved A * algorithm.The improved A * algorithm is used to plan the interaction path in the 3D film and television animation walkthrough, obtain the optimal interaction path, and avoid collision in the interactive display process of the 3D film and television animation walkthrough.
The key part of the A * algorithm is the evaluation function , that is, the source point in the 3D movie animation model to end passing through nodes the total cost of and estimated cost add to get.
The collective steps of the A * algorithm to search for the best path in the 3D movie animation model are summarized as follows: Step Step 3: Repeat step 2 to process the remaining adjacent nodes in order until the open table is empty.
To speed up the search efficiency of the interactive display path of 3D film and television animation roaming, a hierarchical strategy is introduced into the A * algorithm, and the 3D film and television animation model is regarded as a complete map divided into several areas of consistent size.For the obstacles within the boundary line, it is necessary to remove the obstacles first, then solve the scale of the obstacles within the boundary line, add the obstacles within the boundary line in the area with the highest scale, and complete the area division of 3D movie and television animation model in this way.
By setting parameters and , and designing fixed rules, the search algorithm is obtained and used in each area, and the proportion of obstacles in the 3D film and television animation model, is which is the ratio of the total number of nodes occupied by obstacles in the current area to the total number of nodes in the area, and the threshold coefficient is .www.ijacsa.thesai.orgAdopt determine that a certain search algorithm needs to be used in this area and determine that further subdivision is required; The value has a negative correlation with the area division size, a positive correlation with the number of expansion nodes, and a positive correlation with the path search time.According to the relationship between and to establish the following rules:

1) On
, it represents no obstacle in the area, and the shortest optimal path can be obtained directly according to the straight line between two points.If and both are in this area, then this path is the optimal path; if and are not in the same area, search for the middle point between the optimal path and the boundary line of the area in the area and regard the middle point as that of the next area .
2) On , means there are fewer obstacles in the area, and the hierarchical strategy is still adopted to subdivide the area further.
3) On , the number of representative obstacles is consistent with the threshold, or even exceeds the threshold.In this case, the A * algorithm is directly used to search the path.
According to the above rules, searching the path in the interactive display process of 3D film and television animation roaming can effectively divide the big into small maps, which is conducive to processing, selecting the optimal path search method for small maps, speeding up the path search efficiency, and effectively avoiding collision events in the interactive display process of 3D film and television animation roaming.
