The model content is a plurality of forms of content which can be used for representing a three-dimensional model or a two-dimensional model, and comprises pictures, videos, source files or texts and the like.

In an exemplary embodiment, the model content may be graphically presented on a screen for viewing by a user.

The three-dimensional model presentation scheme will be described below by way of various embodiments. The solution may be implemented by a computer device 1000, and the computer device 1000 may be the provider network 2 or a computing node thereof, or may be the mobile terminal 6.

FIG. 2 shows a flow diagram of a three-dimensional model presentation method according to an embodiment of the present application. As shown in fig. 2, the three-dimensional model displaying method may include:

and S210, acquiring three-dimensional model resources.

The three-dimensional model resources may include information such as a modeling concept, an internal core structure, and an external shape of the three-dimensional model. The external shape of the three-dimensional model is used as an expression form of the three-dimensional model, and the appearance effect of the three-dimensional model can be known by browsing the external shape of the three-dimensional model. However, the modeling concept and the internal core structure of the three-dimensional model are the essence of creating the external shape of the three-dimensional model, and the same three-dimensional model can be easily constructed by obtaining the modeling concept and the internal core structure of the three-dimensional model. Therefore, in order to share the three-dimensional model of the user and protect the created three-dimensional model from being stolen, only the external shape of the three-dimensional model can be displayed.

The external shape of a three-dimensional model is typically based on the software rendering that builds the three-dimensional model, i.e., it needs to be in a particular software environment to preview the three-dimensional model. In addition to this, by browsing pictures of a three-dimensional model from a plurality of different perspectives, the external shape of the three-dimensional model can be browsed indirectly.

The three-dimensional model resource may be a three-dimensional model file based on various file formats, such as an STL (stereolithography) format file, an OBJ (object) format file, and the like.

The three-dimensional model resources can be obtained by uploading by a producer, can be obtained from a buffer database, and can also be obtained by calling the three-dimensional model resources in a local database.

In the embodiment of the present application, the three-dimensional model may be obtained by a service platform provided by the provider network 2. Wherein the service platform may be a web application service platform.

In the embodiment of the application, webGL can be called to obtain three-dimensional model resources, so that points, lines and triangles can be drawn according to codes of the three-dimensional model resources, and therefore the external shape of the three-dimensional model can be obtained.

And S220, rendering the three-dimensional model resource, generating a plurality of pictures, and storing the pictures to a file server.

Wherein the plurality of pictures correspond to a plurality of viewing angles of the three-dimensional model.

In the embodiment of the application, the external shape of the three-dimensional model can be rendered through the rendering engine, the visual angles to be rendered are sequentially acquired, the projection corresponding to the visual angles to be rendered is acquired according to the visual angles to be rendered, and the projection is drawn on a canvas to generate a picture. Multiple pictures can be generated corresponding to multiple different visual angles to be rendered. The user can obtain the external shape of the three-dimensional model by browsing a plurality of pictures with different visual angles.

In one example, a user first views a picture at a first view angle, and then, as needed, converts the view angle and views a picture at a second view angle until the viewing is completed.

In the embodiment of the application, the plurality of viewing angles corresponding to the plurality of pictures can be determined according to the specific shape of the three-dimensional model. The multiple perspectives may be system defaults or may be obtained from the configuration of the producer.

In one example, the shape type of the three-dimensional model may be determined by system recognition, and a default plurality of perspectives may be determined based on the shape type.

In one specific example, where the shape type of the three-dimensional model is a human figure, the plurality of viewing angles may be determined as a default plurality of viewing angles between 0 ° to 360 ° for the corresponding side and 45 ° from top to bottom. And then determining the specific angles of the plurality of visual angles according to the default visual angle interval.

In one example, the producer may freely define the view angles of the plurality of pictures that need to be rendered by configuring the pitch view angle range, the side view angle range, and the view angle interval. The view angle interval may be configured as one view angle interval, or different view angle intervals may be configured for the side view angle and the pitch view angle, respectively.

It can be understood that the smaller the viewing angle interval is set, the more continuous the display effect is when the user browses the three-dimensional model, the closer the situation of browsing the real three-dimensional model is, and the better the browsing experience is.

In the embodiment of the present application, the viewing angle interval may be 15 °, 20 °, 25 °,30 °, 45 °, or the like, or may be any value between 15 ° and 45 °.

In one example, a plurality of pictures generated by rendering all have a view identifier corresponding to a view, so as to determine a picture corresponding to the view according to a view to be browsed.

According to the method and the device, after the picture rendering is completed, the generated multiple pictures are stored to the file server, and when the pictures are displayed, the pictures can be directly acquired from the file server to be displayed. The file server may be a server used by the service platform to store data information.

And S230, responding to the browsing request, and determining a specified view angle corresponding to the browsing request.

The user may send a browse request requesting to browse a website of the desired three-dimensional model. When browsing the three-dimensional model, a user may first return a preset preview picture, where the preview picture is a picture corresponding to a preset view angle, and the preview picture is usually a picture that can best embody the external shape characteristics of the three-dimensional model.

Besides browsing the preset pictures, the user also wants to know the pictures of the other multiple viewing angles. The operation of rotating the preview picture can be implemented by operating the mouse to drag or knocking the upper, lower, left and right keys on the keyboard so as to send a browsing request. According to the operation of the user, the rotating angle can be determined, and therefore the specified view angle which the user wants to browse is determined.

In one example, the view angle of the preview picture is (0 ° ), and the user turns 30 ° to the right, then the specified view angle is determined to be (0 °,30 °); the user turns up 30 deg., the specified viewing angle is determined to be (30 deg., 0 deg.).

In the embodiment of the application, the producer can also send a browsing request to request for browsing the address returned by the file server. When the producer browses the address returned by the file server, the producer can also configure the three-dimensional model, for example, configure a preview picture, configure a mode for acquiring the three-dimensional model resource, and the like.

S240, acquiring the picture corresponding to the specified view angle from the file server, and returning to the terminal equipment.

In the embodiment of the application, the image corresponding to the specified visual angle is acquired from the file server, so that the image acquisition speed can be increased. The multiple pictures stored in the file service are provided with view angle identifications corresponding to view angles, so that the pictures corresponding to the specified view angles can be conveniently determined according to the specified view angles.

In one example, the viewing angle interval is 15 °, the viewing angle of the preview picture is (0 ° ), the user turns 28 ° to the right, and the specified viewing angle is determined to be (0 °,30 °), and the picture corresponding to the viewing angle (0 °,30 °) is returned; or determining that the specified view angle is (0 degrees, 28 degrees), and returning to the picture, returning to the picture corresponding to the view angle (0 degrees, 30 degrees).

In one example, the viewing angle interval is 15 °, the viewing angle of the preview picture is (0 ° ), the user turns up and right 30 °, and the picture with the viewing angle is returned (30 ° ).

In an example, after the designated view angle is determined according to the rotation angle, a first weight value may be respectively calculated with respect to two or four adjacent pictures, and a picture corresponding to the designated view angle that needs to be returned is determined according to the first weight value.

For example, when the viewing angle interval is 15 °, it is determined that the specified viewing angle is (0 °,28 °), since 0 ° is at the standard position, two adjacent pictures are pictures of the viewing angle (0 °,15 °) and the viewing angle (0 °,30 °), respectively. A first weight value may be calculated with respect to the pictures of the view angle (0 °,15 °) and the view angle (0 °,30 °), and a picture corresponding to the specified view angle is determined according to the first weight value. The first weight value may be calculated in the following manner: view difference/view interval.

For example, specifying a view angle as (0 °,28 °), a first weight value for a picture relative to the view angle (0 °,15 °) may be (28-15)/15; a first weight value for a picture relative to a view angle (0 °,30 °) may be (28-30)/15; and the first weight value of the picture relative to the view angle (0 degrees and 30 degrees) is smaller, so that the picture of the view angle (0 degrees and 30 degrees) can be determined to be the picture corresponding to the specified view angle.

In other examples, it may also be determined that the picture with the higher first weight value is a picture corresponding to the specified view angle.

In the embodiment of the application, under the condition that a plurality of pictures are generated by rendering and stored as a picture list, a corresponding second weight value can be set for the picture at each view angle.

In one example, after determining the designated angle according to the rotation angle, the first weight value and the second weight value are integrated, for example, a picture corresponding to the designated angle is determined according to a product of the first weight value and the second weight value.

In an implementation manner, the picture corresponding to the displayed specified view angle can be determined according to an x-axis change value and a y-axis change value generated when a user drags a mouse or taps a keyboard.

In the embodiment of the application, a plurality of generated pictures are rendered, and a picture list is generated according to the view angle direction. For example, as shown in fig. 3, pictures of the lower side view angle range of the same pitch view angle are stored vertically, and pictures of the lower pitch view angle range of the same side view angle are stored horizontally.

Taking the picture list shown in fig. 3 as an example, the horizontal axis is an x axis, the vertical axis is a y axis, and it is assumed that when the user clicks and browses the three-dimensional model, an initial value of a displayed preview picture is x =0; y =0 position, x denotes the x-th column in the picture list, and y denotes the y-th row in the picture list. When detecting the operation of dragging a mouse or knocking a keyboard by a user, determining a target x value and a target y value according to the x change value and the y change value, wherein the target x value is as follows: (x initial value + x variation)/7, target y value: (y initial value + y variation)/24; and displaying the pictures corresponding to the target x value and the target y value. Where 7 indicates 7 pictures in each row and 24 indicates 24 pictures in each column.

According to the embodiment of the application, the rendering processing of the three-dimensional model is completed through the service platform, and a plurality of pictures are generated to be used as the display of the three-dimensional model, so that the uploading speed of the model can be increased, the occupation of broadband resources is reduced, and the enthusiasm of a manufacturer for sharing the three-dimensional model is improved; on the other hand, the picture corresponding to the specified view angle is obtained from the file server, so that the picture can be obtained in real time according to browsing requests of different view angles, the browsing speed is increased, and the browsing experience of the user is improved.

In one embodiment, as shown in fig. 4, step S230 further includes:

and S250, determining a preview picture from the plurality of pictures.

And determining a preview picture for the picture browsed first when the user browses the three-dimensional model. The preview picture is usually the picture which can best embody the external shape characteristics of the three-dimensional model.

The preview picture may be a picture corresponding to a default view angle of the system, for example, a picture corresponding to a view angle positioned by a side view angle of 0 ° and a pitch view angle of 0 °.

In one example, the view positioned by the side view angle 0 ° and the pitch view angle 0 ° may be a frontal view angle of the external shape of the acquired three-dimensional model.

In one example, the view angle at which the side view angle 0 ° and the pitch view angle 0 ° are positioned may be a view angle determined according to a shape type of the three-dimensional model. For example, if the shape type of the three-dimensional model is a human figure, the view angle at which the lateral view angle is 0 ° and the pitch view angle is 0 ° can be determined as the view angle at which the face is oriented in the forward direction.

The preview picture can also be determined as a preview picture after the producer receives a plurality of rendered pictures, so that the preview picture can be displayed according to the personalized requirements of the producer. Of course, the preview picture may also be randomly determined.

And S260, responding to the preview request, and returning the preview picture to the terminal equipment.

When the user wants to browse the three-dimensional model, a preview request is first sent by clicking or selecting to view or the like. The service platform acquires a preview picture corresponding to the three-dimensional model under the condition of receiving the preview request, namely responding to the preview request, and returns the preview picture to the terminal equipment; so that the user can preliminarily know the external shape of the three-dimensional model by browsing the preview picture.

In one embodiment, the three-dimensional model display method further comprises: and storing the plurality of pictures to a file server, and returning the addresses of the plurality of pictures to the terminal equipment.

According to the embodiment of the application, the plurality of rendered pictures are returned to the terminal equipment of the manufacturer in the form of the address, so that the manufacturer can browse the plurality of pictures and store the pictures.

In one example, a plurality of rendered pictures may be compressed and then stored in a file server, so as to reduce time and bandwidth consumption during file transmission.

In one example, the original model resource of the three-dimensional model resource may also be saved to a file server, and an address of the original model resource is returned to the terminal device, so that the producer may access the address at any time to obtain the original model resource. On the other hand, sharing of the original model resource can also be achieved, for example, after a user browses a plurality of pictures of the three-dimensional model and wants to acquire the original model resource, the original model resource can be acquired through a request.

In one embodiment, step S250 includes: receiving a specified instruction of previewing a picture; and determining the picture specified by the specified instruction as a preview picture based on the specified instruction.

In the embodiment of the application, the producer can obtain a plurality of pictures from the addresses of the received pictures, select one of the pictures and designate the selected picture as the preview picture, so that the preview picture can be displayed according to the personalized requirements of the producer.

In one embodiment, as shown in fig. 5, step S220 includes:

s221, rendering data is obtained, and the rendering data comprises parameter information of a plurality of visual angles.

The rendering data may be rendering data obtained according to configuration parameters of the producer. In the case where the producer does not configure the rendering data, system default rendering data may be employed.

According to the acquired rendering data, a plurality of visual angles to be rendered can be acquired, and a plurality of pictures corresponding to the plurality of visual angles are generated based on the picture information of the plurality of visual angles.

S222, a canvas is created.

For drawing picture information on the canvas to generate a picture. The Canvas may be a Canvas or the like.

In the embodiment of the application, a canvas can be created in response to the acquired three-dimensional model resources, that is, each received three-dimensional model resource is displayed in a picture mode; the canvas may also be created upon receiving rendering instructions. In case no rendering instructions are received, it is possible that the producer does not need to show the three-dimensional model in the form of pictures, i.e. does not need to protect the three-dimensional model resources. Thus, without receiving rendering instructions, it may be configured to issue an original model of the three-dimensional model resource. By creating the canvas upon receipt of the rendering instruction, multi-dimensional sharing of the three-dimensional model can be facilitated.

The canvas size created may be the size of one picture to be rendered, such that one canvas is used to generate one picture.

The size of the created canvas can also be the size capable of accommodating a plurality of pictures to be rendered, so that the picture information of the plurality of pictures is drawn on one canvas, and then the plurality of pictures are generated from one canvas.

The size of the created canvas can also be the size capable of accommodating a group of pictures in a plurality of pictures to be rendered, so that one group of pictures can be drawn on one canvas, and then a plurality of pictures of the group are generated from the canvas, so that the plurality of pictures can be conveniently stored in a list form to form a picture list.

The size of the picture to be rendered can be the size of the picture limited according to the display requirement of the service platform; or may be a selected one of several defined picture sizes.

S223, determining a to-be-rendered visual angle based on the rendering data, wherein the to-be-rendered visual angle is one of the multiple visual angles.

The rendering data may include an initial rendering perspective, and the calculation rules for the remaining rendering perspectives are determined from the initial rendering perspective; the remaining plurality of perspectives can thus be determined from the initial rendering perspective and the calculation rules. In the case where the rendering data includes only the initial rendering perspective, excluding the perspective range, a default 360 ° range rendering may be determined.

The rendering data may also include a rendering view range and a rendering view interval, so as to determine a plurality of views to be rendered according to the rendering view range and the view interval.

It will be appreciated that the rendering data may be represented in a variety of ways, as long as a plurality of perspectives to be rendered can be determined from the rendering data. And determining one of the multiple visual angles as a visual angle to be rendered to generate a picture for the picture information of the visual angle to be rendered, then determining the next visual angle as the visual angle to be rendered, and sequentially generating the pictures.

S224, drawing the picture information of the view angle to be rendered on the canvas, and generating a picture corresponding to the view angle to be rendered.

The rendering engine may be used to obtain the picture information of the view angle to be rendered, and to draw the picture information on the canvas.
