The execution main body of the rendering method of the physical model provided by the invention is a rendering device of the physical model, and the rendering device of the physical model can be hardware equipment such as terminal equipment and a server provided with a Graphics Processing Unit (GPU), or a controller CPU of the hardware equipment, or software installed on the hardware equipment. In this embodiment, the physical model is an algorithm, and uses variables such as mass, speed, friction, and air resistance to simulate an approximately real physical system, so as to give a real physical effect to the rigid object, such as gravity, rotation, and collision, and make the behavior of the object more real. The physical model algorithm is mainly applied to the field of front-end development, such as a physical engine of game development. Among them, physical engines are, for example, game engines such as cos2dx, aigret, laybox, and three.
Wherein, the physical model algorithm can realize the following characteristics: (1) basic physical properties of an object include mass, position, degree of spin, velocity, and degree of attenuation. (2) The material of the object comprises density, friction and a recovery system. (3) The physical world, including global gravity, refresh rate, sub-steps (number per refresh), boundaries, is an aggregation of objects, constraints, and composite objects. (4) The position and speed of the physical rigid body can be a static rigid body or a dynamic rigid body, and the realization of the static rigid body is to endow infinite quality. (5) And collision, including collision detection. (6) Queries, including point queries, ray queries, and rectangle queries.
In this embodiment, when the physical model algorithm simulates an object, a plurality of continuous image frames are generated; the plurality of image frames are rendered to obtain a simulated physical system which can be observed by a user. Wherein, the fragment is a pixel point with attributes such as position, normal vector and the like. The number of fragments and the complexity of the fragment shader may be obtained from the graphics processor GPU, i.e. the graphics processor GPU analyzes the image frame. In addition, the attribute information of the image frame may further include: number of vertices. The number of the vertexes is the total number of the vertexes of each granularity in the image frame.
And S102, calculating the rendering time of the image frame according to the attribute information of the image frame.
In this embodiment, the process of the rendering device of the physical model executing step 102 may specifically be to obtain a load condition of the GPU; and calculating the rendering time required by the GPU to render the image frames according to the load condition of the GPU and the attribute information of the image frames. The rendering time calculation formula may be as shown in formula (1).
ET is rendering coefficient × SC × PIX; (1)
wherein ET represents rendering time; SC represents the fragment shader complexity; PIX denotes the number of slices. The rendering coefficient is determined according to the load condition, rendering speed and the like of the GPU.

Therefore, the number of objects needing to be rendered is reduced, the rendering speed is increased, the load condition of the GPU is reduced, the probability of rendering errors, frame skipping and other problems is reduced, and the visual experience of a user on the rendered physical model is improved.

and the rendering module 24 is configured to render the at least one image frame according to the rendering frame rate to obtain a rendered physical model.
The rendering device of the physical model provided by the present invention may specifically be a hardware device such as a terminal device and a server on which a Graphics Processing Unit (GPU) is installed, or a controller CPU of the hardware device, or software installed on the hardware device. In this embodiment, the physical model is an algorithm, and uses variables such as mass, speed, friction, and air resistance to simulate an approximately real physical system, so as to give a real physical effect to the rigid object, such as gravity, rotation, and collision, and make the behavior of the object more real. The physical model algorithm is mainly applied to the field of front-end development, such as a physical engine of game development.

In this embodiment, when the physical model algorithm simulates an object, a plurality of continuous image frames are generated; the plurality of image frames are rendered to obtain a simulated physical system which can be observed by a user. Wherein, the fragment is a pixel point with attributes such as position, normal vector and the like. The number of fragments and the complexity of the fragment shader may be obtained from the graphics processor GPU, i.e. the graphics processor GPU analyzes the image frame. In addition, the attribute information of the image frame may further include: number of vertices. The number of the vertexes is the total number of the vertexes of each granularity in the image frame.
Further, the calculation module 22 may be specifically configured to obtain a load condition of the GPU; and calculating the rendering time required by the GPU to render the image frames according to the load condition of the GPU and the attribute information of the image frames.

In this embodiment, in an implementation scenario, for each object in the display content of each image frame, the rendering device of the physical model may call the first interface of the GPU to render the object, thereby implementing the drawing and rendering operations on the entire image frame.

Further, on the basis of the above embodiment, in order to further improve the rendering speed, the content to be rendered may be adjusted according to the type of the graphic display, and correspondingly, the rendering module 24 may be specifically configured to obtain the type of the graphic display; determining at least one visible object in the image frame according to the type of the graphic display; and combining the at least one visible object to obtain a large-class object.
In this embodiment, the type of the graphical display is used to identify the size of the display or the type of hardware device on which the display is located, such as a mobile phone, a computer, or a PAD. When the display is located on the mobile phone, the display is small in size, and it may be difficult to display all objects in the image frame, so that it is necessary to determine the objects that can be currently displayed on the display according to the type of the graphic display; and then the objects which can be displayed are combined to obtain a large class of objects.

Further, in the above embodiment, when the rendering device of the physical model calls the first interface, the formats of the identifiers of the objects or the large-scale objects may be unified first, and then the identifiers with the unified formats are used as parameters to call the first interface, so that the GPU can quickly acquire the data of the objects or the large-scale objects according to the identifiers with the unified formats, and then perform drawing or rendering, and the like, thereby further improving the rendering speed. In addition, the format unifying method can also be used for other interfaces, such as a query interface and the like. The query interface may be getElementsByTagName, for example.
In addition, in this embodiment, the data of the object may be represented by using an analog view matrix. Wherein, the simulation view matrix can represent the relative position relation between each object in the image frame; the simulation view matrix changes only when the relative position of each object changes, so that the same local simulation view matrix may exist in a plurality of image frames, and the same local simulation view matrix can be rendered only once, so that the rendering speed can be further improved.
