- the embodiment of the present disclosure is applicable to dynamic 3D image rendering scenarios, for example, dynamic 3D image rendering in some mini-games, special effects, or prop scenarios that can interact with users.
- the method can be executed by an image rendering device, which can be implemented in the form of software and/or hardware, and the device can be configured in an electronic device, such as a mobile terminal or a server device.
- the image rendering method provided by this embodiment includes:
- the target rendering object may be an interactive video prop, or an interactive animation.
- the target rendering object is a three-dimensional object with depth information.
- the interactive interface of the application client will display the target display object in its initial state, which may be a preset 3D image with initial depth information.
- the three-dimensional model of the target display object may be a corresponding model established in advance based on preset scenes, topics and other relevant content, such as three-dimensional animal models, three-dimensional food models or daily necessities models.
- the user can interact with the target rendering object in the terminal interaction interface displaying the target rendering object.
- the interaction methods include light touch, long press, drag, or gesture recognition.
- gesture recognition refers to the ability to trigger interactive operation instructions on the target rendering object by recognizing the user's gestures (including facial movements), such as changing the movement trajectory of the target rendering object through the movement trajectory of the hand.
- each bone node in its 3D model has an initial depth value.
- the depth value is a constant, indicating the depth from the terminal screen display interface to the camera.
- the change in depth is related to the time when the target rendering object starts to be displayed, or the time when the user interacts with the target display object.
- the depth change can be changed according to the time value. For example, take the cumulative duration of the display of the target rendering object or the sine value of the cumulative duration of interaction between the user and the target display object, and perform numerical operations with the depth constant on this basis to finally obtain updated depth information.
- the obtained depth information is the depth information of the first node in the 3D model of the target rendering object.
- the first node is the skeletal node at the starting position of the target rendering object when it changes dynamically.
- the other skeletal nodes change continuously under the conduction of the change of the position information of the first node according to the corresponding preset node sequence, so as to realize the overall change of the target rendering object.
- the initial display state of the target rendering object is shown in the form of a two-dimensional plane image. This plane can be the coronal plane where multiple nodes of the target rendering object are located.
- the target rendering object as a whole includes multiple model subunits (rhombic blocks), and the black dots exemplarily show the bone nodes of the target rendering object.
- a link node is a node used to link two model subunits together, and a non-link node is a node within a model subunit. When two model sub-units are linked, just overlap the corresponding two link nodes directly.
- the target rendering object When the user interacts with the target rendering object in any feasible way, for example, dragging the target rendering object to move; then, the target rendering object will start to move from the model subunit where the first node is located. As shown in FIG. 3 , when the user moves along the curved trajectory indicated by the curved dotted line through gestures, the target rendering object will also move along the corresponding trajectory. Presentation of the final rendering effect is achieved by calculating the position information of multiple nodes according to the depth change and the space coordinate position change of the first node in the subsequent steps. The content in Figure 2 and Figure 3 does not contain depth information and is not the final rendering effect, it is only for the explanation of the rendering process.
- the target rendering object moves in response to the user's interactive operation instruction, it moves along with the trajectory of the user's finger on the screen or the trajectory corresponding to the gesture on the screen. Then, in each frame of image, the coordinates of the finger on the terminal interface are the target coordinates of the movement of the first node.
- the target coordinate is a movement guide for the first node, and the first node will move closer to the target coordinate, or even coincide with the target coordinate; then, other nodes will pass the path passed by the first node in turn.
- the screen coordinates of the user's gesture movement track in the current image frame can be obtained in real time. Then, the coordinate calculation is performed in combination with the depth information to obtain the target coordinates of the first node in the world coordinate system.
- the rendering process of the target rendering object is the process of calculating and updating the rendering parameters such as the coordinate values of multiple nodes in the 3D model of the target rendering object in combination with the dynamic changes of the target coordinates in each frame of the image displaying the target rendering object.
- the movement of the first node is from the coordinate position in the previous frame image to the target coordinate of the current frame, it is possible to determine the moving direction and moving distance of the first node according to the target coordinates and the world coordinate system coordinates of the first node in the previous frame image, and make the first node move the corresponding moving distance according to the corresponding moving direction to complete the update of the coordinates of the first node in the current frame image.
- the moving direction and moving distance of the first node are based on the world position of the first node in the previous frame image
- the first coordinate vector between the frame coordinates and the target coordinates, the direction of the vector is from the world coordinate system coordinates of the first node in the previous frame image to the target coordinates.
- the vector direction of the first coordinate vector can be used as the moving direction of the first node, that is, the direction of V1 is the moving direction of the first node.
- the unit distance of pixel moving between two adjacent image frames and the length of the vector V1 should be considered.
- the relationship between the preset pixel moving unit distance and the vector length of the first coordinate vector V1 may be determined first.
- the preset pixel moving unit distance is less than or equal to the vector length of the first coordinate vector
- the preset pixel moving unit distance is used as the moving distance of the first node in the corresponding moving direction;
- the preset pixel moving unit distance is greater than the vector length of the first coordinate vector, the moving distance of the first node in the corresponding moving direction is set as the vector length of the first coordinate vector, that is, the moving distance of the first node in the vector direction of V1 will not exceed the length of the vector V1.
- the world coordinate system coordinates of multiple nodes other than the first node in the current frame image are also updated synchronously. Each node except the first node also moves toward the position of the previous point adjacent to it. Then, for a plurality of nodes other than the first node, the moving direction and moving distance of the node can be determined according to the world coordinate system coordinates of each node and its adjacent previous node in the previous frame image, and the node is moved according to the corresponding moving direction by the corresponding moving distance to complete the update of the coordinates of the multiple nodes in the current frame image.
- the second coordinate vector V2 between the world coordinate system coordinates of each node and its adjacent previous node in the previous frame image can be used; then, the vector direction of the second coordinate vector is used as the moving direction of the node; when the preset pixel moving unit distance is less than or equal to the vector length of the second coordinate vector, the preset pixel moving unit distance is used as the moving distance of the node in the corresponding moving direction; The length is used as the moving distance of the node in the corresponding moving direction. That is, between two adjacent frames of images, the pixel moving unit distances corresponding to different pixel points are consistent, that is, the moving distances of multiple nodes in their respective moving directions are consistent.
- the plurality of nodes other than the first node include link nodes and non-link nodes (as shown in FIG. 2 ).
- the preset distance between nodes should be considered. After the moving of non-link nodes, the distance between adjacent non-link nodes cannot be less than the preset distance between nodes. Then, in the process of determining the moving distance of non-link nodes, first, it is necessary to determine whether the distance difference between the vector length of the second coordinate vector and the distance between the preset adjacent nodes is greater than or equal to the preset pixel moving unit distance; on the moving distance. If the distance difference between the vector length of the second coordinate vector and the preset distance between adjacent nodes is less than the preset pixel movement unit distance, the distance difference is used as the moving distance of the non-linked node in the vector direction of the second coordinate vector.
- the multiple nodes can complete the moving process. After the movement is completed, the world coordinate system coordinates of multiple nodes in the current frame image can be updated.
- the multi-nodes will also rotate around the coordinate axes of the 3D model itself during the moving process, so as to realize the visual rendering effect of spiral moving forward.
- Different rotation strategies are set for different nodes.
- the first node is controlled to rotate a preset angle around a preset coordinate axis of the target rendering object toward a vector direction of the first coordinate vector.
- the preset angle is a fixed angle value, and the same angle is rotated each time of rotation.
- each node is controlled to rotate towards the vector direction of the second coordinate vector around the preset coordinate axis of the target rendering object, and the rotation angle is the rotation angle of the previous node adjacent to the node during the process of updating the coordinates in the previous frame image.
- the non-linked node can be controlled to rotate towards the vector direction of the third coordinate vector of the next adjacent node and the previous node in the previous frame image, and the rotation angle is less than or equal to the rotation angle of the previous node adjacent to the node during the process of updating the coordinates in the previous frame image.
- Such a setting can make the rendering effect of the rotation smoother and less abrupt.
- an interactive operation instruction for the user to move and control the target rendering object can be obtained; then, during the interaction process of the user performing movement control on the target rendering object, for each frame image of the target rendering object, update the depth information of the first node of the 3D model of the target rendering object in the current frame image; according to the screen coordinates and depth information corresponding to the movement track corresponding to the interactive operation instruction in the current frame image, determine the target of the first node in the current frame image corresponding to the world coordinate system Coordinates: take the target coordinates as the overall moving target position of the target rendering object, based on the target coordinates and the world coordinate system coordinates of multiple nodes in the current frame image and the previous frame image in the 3D model, synchronously update the world coordinate system coordinates of multiple nodes in the current frame image frame, and control multiple nodes to rotate according to the preset model node rotation strategy during the coordinate update process to complete the image
- the technical solutions of the embodiments of the present disclosure make up for the gap in the dynamic three-dimensional image rendering scheme with depth changes, and realize a rendering method in a deep three-dimensional space, so that the rendering object presents a depth change during the movement of the corresponding trajectory, and different parts of the rendering object will also perform curved movements during the movement of the corresponding trajectory.
- the embodiments of the present disclosure may be combined with the solutions in the image rendering method provided in the foregoing embodiments.
- the image rendering method provided in this embodiment describes the process of dynamic rendering of a three-dimensional image in the scene of adding model subunits.
- FIG. 4 is a schematic flowchart of an image rendering method provided by Embodiment 2 of the present disclosure. As shown in Figure 4, the image rendering method provided in this embodiment includes:
- the preset object in the space is a preset object with depth information, which can be randomly set at multiple positions in the space where the target rendering object is displayed, or can be set at multiple positions in the space according to a certain setting strategy.
- a model update instruction of the target rendering object will be triggered.
- the user can drag the target rendering object to preset objects in multiple spaces according to a certain movement track. Therefore, in the process of rendering the target rendering object, the client will add a model subunit to the 3D model of the target rendering object when receiving the model update instruction.
- the rendering effect of the model update it is equivalent to increasing the 3D model of the target rendering object in one dimension, such as increasing the height and side length.
- the preset objects in the space can be set in the form or content associated with the prop scene, for example, in some mini-games, the target rendering object is controlled to move to obtain food or score in the game, such as Snake.
- FIG. 5 is a two-dimensional plan view to add a model sub-list A schematic diagram illustrating the process of the meta.
- small triangles represent preset objects in the space.
- a preset model subunit (dashed diamond box) is added at the link node before the tail model subunit.
- the reason why it is added before the tail model subunit is that, usually in the target rendering object model, the head model subunit and the tail model subunit are different in terms of modeling structure, and the added preset model subunit is a uniformly set subunit. If the tail model subunit is the same as the preset model subunit, the preset model subunit can be directly added after the tail model subunit, and the added preset model subunit can be used as a new tail model subunit.
- a preset model subunit usually includes multiple nodes. The more nodes, the smaller the corresponding skin coverage, the better the effect after rendering, and the more realistic the moving state of the target rendering object.
- the initial values of the rendering parameters of multiple nodes of the newly added model subunit are usually set to the rendering parameter values of the nodes of the previous model subunit adjacent to it. For example, set the coordinate positions and rotation angles of all nodes in the newly added preset model subunit to be the same as the corresponding values of a node in front of the tail model subunit.
- the target rendering object after the model is updated the rendering effect can show the effect of the dynamic growth of the snake model.
- animation special effects may also be added to the non-node parts in the 3D model of the target rendering object.

- the target rendering object is a dragon
- its 3D model is shown in FIG. 6 , where the dots represent nodes in the 3D model, and the nodes at the positions indicated by the two arrows are the positions of two link nodes.
- the dragon model is divided into three sections with the position of the link node as the dividing line. These three sections are the head model subunit, the middle body of the dragon obtained by linking multiple identical model subunits in the middle, and the tail model subunit.
- the initial rendering state of the dragon can be displayed on the terminal screen. Then, during the interaction with the terminal interface, the user can drag the faucet with his hand to make the dragon move along the sliding track of the user's gesture. move.
- the client updates the depth information of the first node of the dragon's 3D model (the first node of the head) in the current frame image in each frame image; then, according to the screen coordinates and depth information corresponding to the user's gesture movement trajectory in the current frame image, determine the target coordinates of the first node in the world coordinate system corresponding to the current frame image; finally, based on the target coordinates and the world coordinate system coordinates of multiple nodes in the dragon's 3D model in the previous frame image of the current frame image, synchronously update the world coordinate system coordinates of multiple nodes in the current frame image frame, and During the update process, multiple nodes are controlled to rotate according to the preset model node rotation strategy, showing the rendering effect of a three-dimensional dragon with depth changes and position changes.
- the position of the gold coin is the position where the node is preset to increase the prompt information.
- the length of the dragon's body can be increased by one unit.
- the body of the dragon with this unit length corresponds to a preset model subunit. For example, add a preset model sub-unit in front of the dragon’s tail sub-model, and assign values to the rendering parameters of the model sub-unit, so as to obtain a rendering effect of a dragon in motion, with dynamically changing depth and growing body.
- the non-skeletal node parts such as the dragon's horns, tail, and feet can also be rendered with animation special effects, making the rendering of the entire dragon more vivid and agile.
- the skin effect can be set to the structure in Figure 7, covering the surface of the model, and the unit area of the skin should not be set too large.
- an interactive operation instruction for the user to move and control the target rendering object can be obtained; then, during the interaction process of the user performing movement control on the target rendering object, for each frame image of the target rendering object, update the depth information of the first node of the 3D model of the target rendering object in the current frame image; according to the screen coordinates and depth information corresponding to the movement track corresponding to the interactive operation instruction in the current frame image, determine the target coordinates of the first node in the current frame image corresponding to the world coordinate system ;
- the target coordinates as the overall moving target position of the target rendering object, based on the target coordinates and the world coordinate system coordinates of multiple nodes in the 3D model in the previous frame image of the current frame image, synchronously update the world coordinate system coordinates of multiple nodes in the current frame image frame, and control multiple nodes to rotate according to the preset model node rotation strategy during the coordinate update process, and complete the
