[0048] S3, preprocessing the business card data to distinguish the three-dimensional model position corresponding to the business card data;

[0049] S4, create renderer, 3D scene and camera;

[0050] S5, loading the 3D model file and processing it;

[0051] S6, injecting the three-dimensional scene and the three-dimensional model into the business card three-dimensional scene carrier;

[0052] S7, rendering the three-dimensional scene based on the renderer, the three-dimensional scene and the camera;

[0053] S8. Set the interactive animation of the three-dimensional model in the business card.

[0054] Further, such as Figure 2 As shown, S4 is specifically:

[0055] S41, creating a renderer and a rendering carrier element; the rendering carrier element is an important carrier for displaying the electronic business card on the front end, and is responsible for presenting the three-dimensional model, lighting effects, etc. in the business card to the user in a visual form;

[0056] S42, the renderer associates a rendering carrier element;

[0057] S43. Create a three-dimensional scene carrier; the three-dimensional scene carrier is the carrier of the entire electronic business card three-dimensional scene. All models, lights and other elements are added to this scene. The complete electronic business card display effect is constructed through the setting and operation of the scene.

[0058] S44, create a camera;

[0059] S45. Set the camera's viewing angle and position parameters.

[0060] Parameters determine the effect of the three-dimensional scene seen by the user, such as adjusting the viewing angle by setting the position of the camera and the target point to look at.

[0061] Further, such as Figure 3 As shown, S5 is specifically:

[0062] S51, loading an external 3D model file;

[0063] S52, traversing the child nodes of the 3D model file;

[0064] S53, setting a texture for the material of the 3D model subnode and loading it;

[0065] S54, setting the scaling ratio of the three-dimensional model so that the loaded model can be displayed in the electronic business card scene in a suitable form.

[0066] Further, such as Figure 4 As shown, S8 is specifically:

[0067] S81, monitoring touch events and obtaining coordinate information of touch points;

[0068] S82, using a ray projector to calculate the intersection of the ray and the object in the three-dimensional scene;

[0069] S83, setting a controller to control the three-dimensional model and adjusting the display state of the three-dimensional model;

[0070] S84. Create an animation mixer;

[0071] S85, obtaining the animation clips of the three-dimensional model;

[0072] S86. Set custom animation effects to achieve smooth animation effects, making the model display in the electronic business card more vivid and attractive;

[0073] S87. Create and play animation actions.

[0074] Furthermore, in S83, the display state of the three-dimensional model is adjusted by setting the rotation speed, zoom speed, scene container, viewing angle, animation loop, and ambient lighting.

[0075] In the embodiment of the present invention, the viewing angle includes the field of view, aspect ratio, near clipping plane and far clipping plane of the perspective camera, the animation loop refers to the animation update effect of rendering each frame of the scene, and the ambient lighting includes ambient light, point light source, directional light, etc.

[0076] Furthermore, in S86, a custom animation effect is achieved by setting the target value, duration, easing function, effect delay, number of loops, and animation weight of the animation.

[0077] In an embodiment of the present invention, the target value represents the final state of the object attributes at the end of the animation, namely, the coordinate position, rotation angle, and scaling ratio, which are key factors in shaping the final form of the animation; the duration determines the time span experienced by the animation from the beginning to the end. In seconds or milliseconds, it directly affects the rhythm and sense of speed of the animation. A longer duration will make the animation look slower and smoother; while a shorter duration will make the animation appear hasty and fast; the easing function controls the speed change law of the animation within the duration, and different speed curves control the overall model to show different motion textures; the effect delay indicates the waiting time before the animation starts. In a complex animation sequence, a delay is set to allow different animation elements to proceed in sequence or staggered; the number of loops and the mode control the number of animation loops; the animation weight is used to control the relative importance of the animation when mixing multiple animation effects, and the weight of each animation can determine its contribution to the final animation effect.

[0078] In one embodiment of the present invention, after the user completes creating a business card, he or she can share the business card WeChat applet link or the business card h5 page, and click to open the link to view the business card.

[0079] In one embodiment of the present invention, a user can create his or her own business card, or upgrade to a business card as a business administrator, and invite members of the business to enter the business card, which becomes a display of the corporate image;

[0080] Users can edit the information corresponding to the 3D model according to the operating instructions, and can also add background music to generate a unique business card;

[0081] Users can share their edited exclusive business cards through social platforms and start business social networking with one click.
