It will be understood by those skilled in the art that the present application may be practiced without certain of the specific details. In some instances, methods, means, components and circuits well known to those skilled in the art have not been described in detail in order to highlight the gist of the present application.

Further, the concepts involved in the embodiments of the present application are briefly introduced below.

Photorealistic rendering (Photorealistic Rendering) is an important part of computer graphics, and its basic requirement is to generate realistic graphics images of three-dimensional scenes in the computer. Realistic graphics has been widely used, and has played an important role in many aspects such as computer-aided design, multimedia teaching, virtual reality system, scientific computing visualization, animation production, movie stunt simulation, computer games, etc. Computers have more and more stringent requirements on visual experience, which requires us to study more and more realistic photorealistic image generation algorithms. For objects in the scene, in order to obtain its realistic image, it is necessary to perform perspective projection on it, and hide the hidden surface, and then calculate the lighting and darkening effect of the visible surface to obtain the realistic image display of the scene. However, the realism of the image obtained by only removing the hidden surface of the scene is far from enough. How to deal with the light and dark effects on the surface of the object, by using different color grayscales, to increase the realism of the graphic image, which is also the scene image The main source of realism.

Non-photorealistic rendering (NPR), also known as stylized rendering. Non-photorealistic rendering does not care about reproducing the objective world as realistically as a photo. It focuses more on the personalized and artistic expression of graphics, emphasizing the differential expression and transmission of data and information. In non-photorealistic rendering, active choices need to be made about what to render and how. For the content creator (Content Creator), what he thinks is important should be expressed in a way that he thinks is appropriate, but the visual reality of the created content is not the focus of consideration. Non-photorealistic rendering is often implemented by an application that takes an image or 3D solid as input and outputs an image in a specific artistic style.

Netural Style Transfer: From the image level, art has developed so far, and there are many different styles of art, such as ink style, cartoon animation style, impressionism, oil painting style, etc., and style transfer refers to the visual transformation of an image. Style becomes another style.

Rasterization is to display three-dimensional objects on a two-dimensional screen, which is fast and effective. With rasterization technology, a 3D model of an object can be created from a virtual triangular or polygonal mesh. In this virtual mesh, the vertices of each triangle intersect with the vertices of other triangles of different sizes and shapes. Each vertex has a lot of information associated with it, including its position in space and information about its color, texture and its "normal", which can be used to determine the orientation of the object's surface. The computer then converts the triangles in the 3D model into pixels or points on the 2D screen. Each pixel can be assigned an initial color value based on the data stored in the triangle vertices. Further pixel processing, or "shading," involves changing the color of a pixel based on how light in the scene collides with it, and applying one or more textures to the pixel to generate the final color applied to the pixel. Rasterization techniques are unusually computationally intensive. All object models in a scene can use up to millions of polygons, nearly 8 million pixels in a 4K display. Also, each frame or image displayed on the screen is typically refreshed on the monitor 30 to 90 times per second.

The terminal devices involved in the embodiments of the present application may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems. The terminal is a mobile station (mobile station, MS), a subscriber unit (subscriber unit), a cellular phone (cellular phone), a smart phone (smart phone), a wireless data card, a personal digital assistant (personal digital assistant, referred to as: PDA) computer, Tablet computer, wireless modem (modem), handheld device (handset), laptop computer (laptop computer), machine type communication (machine type communication, MTC) terminal, etc.

Graphics rendering is the process of converting a three-dimensional radiosity process into a two-dimensional image. Scenes and entities are expressed in three-dimensional form, which is closer to the real world and easy to manipulate and transform, while most of the graphics display devices are two-dimensional rasterized displays and dot-matrix printers. From the representation of the three-dimensional entity scene to N--dimensional raster and lattice representation is graphics rendering - that is, rasterization. The raster display can be regarded as a pixel matrix, and any graphic displayed on the raster display is actually a collection of pixels with one or more colors and grayscales. Please refer to the system architecture diagram of graphics rendering shown in FIG. 1 , the system includes a terminal device 1 and a server cluster 2 .

Among them, the terminal device 1 is the device used by the user to view the rendered 3D scene (that is, the 3D image). The user can log in to the server cluster 2 through a browser or an application program, and then send a rendering command to instruct the server cluster 2 to The 3D scene is rendered, and the rendered 3D scene is displayed through a browser or an application program.

The server cluster 2 can be one or more cloud servers, or one or more server clusters in any data center. Before graphics rendering, according to the data of the pre-saved 3D scene, through 3D scanning, 3D interactive geometric modeling and 3D model library to obtain 3D geometric model information; obtain 3D animation definition information from motion design, motion capture, motion calculation and dynamic deformation; obtain material information from scanned photos, computer calculated images or human-drawn pictures , and then process the 3D scene to be rendered into a rendered 3D scene through geometric transformation, projection transformation, perspective transformation and window clipping according to the rendering command from terminal device 1, and then through the obtained material and light and shadow information, and send it to Terminal device 1.

Optionally, the solution of the present application may also be executed by a rendering system, which may execute a rendering process of a 3D scene and display the rendered 3D scene.

At present, for a certain spatial range or 3D scene, a single rendering style is generally used to render and visualize the entire spatial range or 3D scene. The switching of various rendering styles is based on global switching, and the rendering flexibility is not high.

In order to solve the above problem, based on the above system architecture, the 3D scene rendering method in the embodiment of the present application will be described with reference to FIG. 2 .

Please refer to FIG. 2, an embodiment of the 3D scene rendering method of the present application includes:

201. The terminal device sends an operation instruction for rendering the 3D scene to be rendered to the server cluster.

In the embodiment of the present application, the 3D scene to be rendered is composed of pre-imported 3D data, and the server cluster can form a 3D model based on the 3D data imported by the user. The complete 3D model diagram is the 3D scene to be rendered. The 3D scene is generated by the server cluster according to the pre-imported 3D data. Each 3D element in the 3D data refers to the most fine-grained user interface (UI) element, does not contain business logic. The 3D scene generated by the server cluster includes multiple components, and each component is an independent whole composed of one or more 3D elements (hereinafter referred to as elements) and their business logic, and components can be nested. Each 3D scene or each feature is an independent component, that is, the 3D data of each element in the 3D scene is pluggable 3D data, and the server cluster can automatically locate the 3D data of different elements. The user can issue an operation instruction to render the 3D scene to be rendered to the server cluster through the terminal device, wherein the operation instruction can include at least two rendering styles, and the user can select multiple areas in the 3D scene and set them respectively Rendering style, or, the user can set different rendering styles for different object types in the 3D scene.

For the 3D scene to be rendered above, it may be the 3D scene selected by the user to be rendered among multiple pre-built 3D scenes, or the 3D data to be rendered may be directly provided by the user. For example, in the acquisition operation Before the instruction, the server cluster may also acquire 3D data, and construct the 3D scene according to the 3D data. Wherein, the three-dimensional data is a collection of multiple independent three-dimensional elements that can be displayed on a graphical user interface (graphical user interface, GUI). The three-dimensional data is imported by the user before rendering, so that the server cluster constructs a three-dimensional scene according to Action instructions perform rendering.

Optionally, the server cluster may obtain an operation instruction for rendering a 3D scene generated after the user interacts with the terminal through a mouse, keyboard, voice or gesture. That is: the operation instruction may be generated by the user interacting with the terminal device through mouse, keyboard, voice, gesture and other possible ways. Users can also determine the scope of operation and select the rendering style in the scene to be rendered, so as to change the spatial scale, region and feature combination, and rendering style through rich and intelligent interactive methods to achieve a good user experience.

Exemplarily, the voice interaction logic may be: the user issues a voice command, the terminal device records the user's audio in real time, the voice recognition service of the terminal device recognizes the incoming audio stream data, and then transmits the recognized command to the server cluster in real time.

The gesture interaction logic can be as follows: the user interacts with the terminal device through gesture actions, the terminal device with the hand tracking function obtains the user's hand state in real time, and uses the gesture recognition service of the terminal device to identify the user based on the stream data of the hand state gesture command, and then transmit the command to the server cluster. The manner in which the user issues an operation instruction is not limited in this embodiment of the present application.

The rendering style includes a photorealistic rendering style and a non-photorealistic rendering style, wherein the non-photorealistic rendering style may include an ink painting style, a sketch style, a cartoon style, a line drawing style or other forms that focus on depicting specific information.

202. The server cluster renders different regions in the 3D scene according to different rendering styles according to the operation instructions, and obtains the rendered 3D scene.

The server cluster can determine the area corresponding to each rendering style according to the operation instructions. The area corresponding to the rendering style is the viewing area when the user sets the rendering style in the 3D scene. The 3D data is rendered with a corresponding rendering style, and the rendered 3D scene is obtained, that is, the required 3D image is obtained.

For the rendering process, take the rendering style as an example of a stylized visualization scheme based on non-photorealistic rendering of graphics. The main process is to calculate the color, transparency, illumination, outline and stroke effects of the model surface according to different styles, and finally The individual renderings are combined to form the final effect. Taking the cartoon rendering style as an example, the server cluster expresses the cartoon style through the rendering of the outline of the object and the rendering of the internal shading. Firstly, contour line rendering is obtained through the steps of contour line extraction algorithm, stroke texture mapping and smudge blurring, and secondly, the cartoon-style light intensity is calculated through the cartoon rendering lighting model, and the color is simplified and offset to adjust the color lighting of warm and cold tones , and finally combine the two parts of the rendering to obtain a cartoon-style drawing effect.

Optionally, the operation instruction further includes at least two operation ranges, each operation range corresponds to a rendering style, and the server cluster renders regions within different operation ranges in the 3D scene according to the corresponding rendering style according to the operation instruction.

In the embodiment of the present application, the terminal device can directly carry the operation range corresponding to the rendering style in the operation instruction, and the operation range can be determined by the user on the terminal device. For example, the operation range can be directly dragged by the mouse The selection method can also be through voice interaction. For example, the user can "select ** city" through voice, or directly drag and adjust through gesture interaction.

After obtaining the operating range, the server cluster can automatically locate the target data to be rendered for the 3D data within each operating range in the 3D scene, and then render the 3D data within the operating range based on the rendering style corresponding to the operating range. Specifically, For 3D data in different operating ranges, the rendering styles can be the same or different. Exemplarily, the user may define an operation range for the server cluster, and then set a rendering style for the operation range, and then continue to define another operation range, and set another rendering style accordingly. The server cluster can render and display each operation range and corresponding rendering style in real time, or perform rendering and display after receiving operation instructions including all operation ranges and corresponding rendering styles, which is not limited in this embodiment.

Optionally, the operation instruction also includes at least two object types, each object type corresponds to a rendering style, and the server cluster determines the rendering area corresponding to each object type in the 3D scene according to the at least two object types; The rendering area corresponding to each target type is rendered according to the corresponding rendering style.

In this embodiment of the present application, the operation instruction may further include a target type, which indicates an element in the rendered 3D scene, where each target type corresponds to a rendering style, and the rendering styles of different target types may also be the same. The server cluster can directly locate the rendering area where the element is located and the 3D data according to the target type, and then perform rendering of the rendering area corresponding to the rendering area on the rendering area.

When the operation instruction includes the operation range, target type and rendering style at the same time, the element indicated by the target type can be an element within the operation range, and the server cluster can perform the rendering corresponding to the target type on the element indicated by the target type within the operation range style rendering.

Optionally, the target type may include one or more elements to be rendered, and each element corresponds to a rendering style, or multiple elements in the target type correspond to a rendering style. That is, the user can indicate that one or more elements within the operating range need to be rendered, and configure corresponding rendering styles for each element. The rendering styles of each element can be the same or different. Elements can be mountains, buildings, Any of the constituent elements of 3D scenes such as rivers and people, or a combination of certain items based on certain rules and restrictions, such as the combination of all elements in a geographical area or the combination of all mountains in a geographical area. Optionally, one target type may only correspond to one element, and in this case, the operation instruction may include multiple target types.

Optionally, each rendering style may also include at least two priority parameters, at least two priority parameters are set according to different 3D scenes, the priority parameters are obtained by user settings, and each priority parameter may correspond to a 3D scene Part of the 3D data, by comparing the priority parameters, adjust the rendering degree of the 3D data corresponding to some or all of the priority parameters. Specifically, the adjustment may include enhancement, that is, enhancing the rendering degree of the highest priority 3D data in the rendered 3D scene. That is, for example, for the rendering results of each rendering style, there will be clear parts and blurred parts (for example, for the "ink painting style" of the mountain, the focus is on the boundary or edge of the mountain, and other elements on the mountain are unimportant data, can be hidden, then the boundary or edge part is a clear part, and other parts are a blurred part), in this embodiment, the user can make further adjustments to the clear part or blurred part of the rendering result, for example, the clear part or the blurred part (for example, when enhancing the rendering of the clear part, for the "ink painting style" of the mountain, it can be used to thicken the boundary or edge of the mountain, etc., which is not limited here). Specifically, the user can set the The corresponding priority parameters are configured for the part and the blurred part, and the rendering degree corresponding to the 3D data with a higher priority parameter is enhanced, that is, the drawing of the clear part is clearer, and the drawing of the fuzzy part is more blurred. Optionally, according to specific requirements, the blurred part can also be divided into multiple levels, corresponding to different business priorities, so as to obtain better rendering effects.

203. The server cluster sends the rendered 3D scene to the terminal device.

After the server cluster renders the 3D scene according to the operation instruction, it can transmit the rendered 3D scene to the terminal device through the network.

204. The terminal device displays the rendered three-dimensional scene.

After the browser or application program sent by the user on the terminal device receives the rendered 3D scene, it receives the 3D image sent by the server cluster, and the terminal device can display the 3D image on the screen through the browser or application program. Rendering results can be viewed in real time. When the terminal device displays the rendered 3D scene, when the user needs to view it, the terminal device inputs a display instruction to the server cluster, and then the server cluster displays the rendered 3D data to the user. Specifically, the user can also rotate or zoom in on the rendered three-dimensional scene by using a rotation command, a zoom-in command, and the like.

Optionally, the server cluster may also obtain adjustment parameters, and adjust the rendered 3D data according to the adjustment parameters.

The adjustment parameter is a parameter set by the user for adjusting the rendered 3D data based on his or her own needs or experience, and may be brightness information, color information, texture information or other empirical parameters related to the form of expression. Specifically, it may be The adjustment parameters issued by the user in which operating range correspond to the operating range, which may also be the rendering results of which target types need to be adjusted, or the rendering results of target types under a certain operating range. The manner in which the user issues an adjustment parameter may refer to the manner in which the user issues an operation instruction in step 201, which will not be repeated here.

Optionally, after the server cluster adjusts the rendered 3D data according to the adjustment parameters, it can also feed back the adjusted 3D scene to the terminal device in real time, and the terminal device can display the adjusted 3D scene in real time. Based on real-time visual feedback, Users can continue to modify and adjust parameters according to the visual feedback to obtain better rendering effects.

In an example, the rendering process of this embodiment of the application may be: the user first sends out the voice command "Luohu District, Shenzhen City", after the server cluster jumps the map to the destination, the user can use gestures to drag the map to explore on the map Determine a certain urban area of interest as the operation range, which includes the city 31, "mountain" 32, and "river" 33, where the city 31 is an element that does not need to be rendered, and the user can select the target type "mountain" 32 with a voice command And the rendering style "ink painting style" corresponding to the "mountain" 32, and the target type is "river" 33 and the corresponding rendering style "cartoon style", the server cluster can obtain the preliminary rendering results according to the operation instructions, and then feed back to The terminal device enables the terminal device to display the rendered 3D scene for the user to view. Users can add their own preferences and experiences, and manually adjust parameters such as the overall brightness of the rendering result by adjusting the parameters. The final real-time rendering result can be shown in Figure 3.

In the embodiment of the present application, by performing rendering corresponding to the corresponding rendering styles for the 3D data in different regions in the 3D scene according to the operation instructions, at least two rendering styles can be implemented in the 3D scene, and the rendering flexibility is improved.
