Description

Image display optimization method and device for dynamically adjusting LOD Scale
Technical Field
The invention belongs to the technical field of computer graphics software development, and particularly relates to an image display optimization method and device for dynamically adjusting an LOD Scale.
Background
Lod (levels of detail) is a level of detail model proposed by the Clark scholars, and refers to a method for describing different objects or different parts of objects in a scene in different details. Specifically, the LOD technique can determine resource allocation for object rendering according to the position and importance of the model node of the object in the display environment, and reduce the number of faces and detail of non-important objects, thereby obtaining efficient rendering operation. The detail level model can observe the details of the model when the user viewpoint is close to the object, and the observed details are gradually blurred when the user viewpoint is gradually far away from the model. The detail level model can avoid time waste caused by drawing details with relatively small significance, so that the generation and display speed of the complex scene is improved. The detail level model is widely applied to the fields of interactive visualization, virtual reality and the like.
In the process of large-scale graphic rendering, the model needs to be subjected to LOD (level of detail) level of detail processing according to factors such as visual range, model complexity and the like. However, in the conventional static LOD mode, the detail level can only be displayed according to the preset LOD Scale no matter whether the rendering performance is excessive. Therefore, when the vertex and the graphic data in the rendered scene are excessive, the frame rate of display is lower than the index requirement; when the vertex and graphic data in the rendered scene are less, rendering performance is excessive, and the frame rate is far higher than the index requirement, but the excessive performance cannot be used for improving rendering details, so that performance waste is caused. Such problems are particularly prominent for domestic hardware platforms where graphics rendering capabilities are relatively weak.

Detailed Description
The invention is described in detail below by way of example with reference to the accompanying drawings.
To facilitate understanding and defining the technical content to which the invention relates, the terms referred to within the invention are defined as follows:
the display details of an image refer to the characteristic elements used by the computer system to display the image. The characteristic elements comprise a vertex number, a primitive number, a line segment number, a geometric figure number and the like. For example, an image in a computer system usually consists of many vertices, and the larger the rendered scene is, the larger the number of vertices contained in the image is, the more the rendering details are, and the system needs to consume more performance resources to process the vertices, and vice versa.
The LOD Scale is a detail Scale parameter of the LOD in the image rendering process, and the larger the Scale value is, the less the display detail of the image in the unit length is, the less the rendering data amount is, and vice versa.
Frame rate, which may also be referred to as frame frequency, refers to the frequency at which bitmap images in frames appear continuously on a display, and this term is equally applicable to film and video cameras, computer graphics, and motion capture systems.
The invention provides an image display optimization method and device for dynamically adjusting LOD Scale, which has the core idea that: and dynamically adjusting the value of the LOD Scale according to the current system performance and the display details of the scene to be rendered so as to ensure that the frame rate meets the determined index requirement.
The image display optimization method for dynamically adjusting the LOD Scale provided by the invention has the flow shown in FIG. 1, and comprises the following steps:
step 1.1, setting the maximum value FR of the system frame rate dereferencing according to the index requirement of the system frame ratemaxAnd minimum value FRmin(ii) a Obtaining LOD Scale value currently adopted by the system as initial value s of Scale0Setting the maximum value S of ScalemaxAnd minimum value Smin。
Step 1.2, obtaining the current frame rate FR of the system, if the current frame rate is larger than the maximum value, namely FR > FRmaxThen step 1.3 is executed; if the current frame rate is less than the minimum value, i.e. FR < FRminThen step 1.4 is executed; if the current frame rate is less than or equal to the maximum value and greater than or equal to the minimum value, FR is obtainedmin≤fr≤FRmaxThen step 1.5 is performed.
Step 1.3, reducing the value of the Scale according to the set step, and if the value of the current Scale is not less than the minimum value SminIf so, rendering by taking the new Scale value as the LOD Scale, and then executing the step 1.2; otherwise, step 1.5 is performed.
Step 1.4, increasing the value of the Scale according to the set step, and if the value of the current Scale is not more than the maximum value SmaxIf so, rendering by taking the new Scale value as the LOD Scale, and then executing the step 1.2; otherwise, step 1.5 is performed.
And step 1.5, stopping adjustment and ending the process.
In the above process, S is usually set according to experimental experiencemaxIs 4.0, SminThe value of (a) is 1.0, and the adjustment step of Scale is 0.1; maximum value FR of system frame ratemaxThe value is usually set to be higher than the frame rate index requirement by 30%, and the minimum value FRminUsually set to the value required by the frame rate index.
In the above process, the problem of adjusting the LOD Scale too frequently due to fine adjustment may occur, which may increase the performance overhead of the rendering process. Because the display details have high correlation with the frame rate and are important factors causing the change of the frame rate, in order to solve the problems, the invention adds a process of learning the corresponding relationship between the Scale value and the frame rate and the display details in advance, namely, the corresponding relationship between the Scale value and the display details after the Scale value is finely adjusted each time is recorded in the learning process, in practical application, if the frame rate is lower than an index requirement or higher than the index requirement, the corresponding Scale value is determined by searching the recorded corresponding relationship according to the monitored current frame rate value, and the Scale value is rendered without fine adjustment again, thereby effectively reducing the performance overhead caused by fine adjustment.
Specifically, the process of learning the correspondence relationship among the Scale value, the frame rate, and the display details in advance, as shown in fig. 2, includes the following steps:
step 2.1, initialize the array SC, the array SC is used to store the Scale value and the ScaDisplay details corresponding to le value, where Scale value is such that frame rate FR satisfies condition FRmin≤fr≤FRmaxThe value of (a).
The value range of the Scale value s determined according to experience is that s is more than or equal to 1 and less than or equal to 4, and the step is 0.1, so the array SC is an array with the length of 31. For example, SC [1 ]]10, wherein, SC [1 ]]The corresponding s value is s 1+ 1/10; and the element SC [1]Has an element value of 10, which means that when s is 1.1, there are 10 vertices in the scene, and the frame rate FR at this time can satisfy FRmin≤fr≤FRmaxOf (3) is performed.
Step 2.2, monitoring the value of the system frame rate, if the current frame rate is less than or equal to the maximum value and greater than or equal to the minimum value, then FR is obtainedmin≤fr≤FRmaxThen step 2.4 is performed. If the current frame rate FR < FRminOr FR > FRmaxThen step 2.3 is performed.
Step 2.3, if the current frame rate is less than the minimum value, FR is less than FRminIncreasing the value of the Scale according to the set step, and if the value of the Scale is not more than the maximum value SmaxIf so, rendering by taking the new Scale value as the LOD Scale, and then executing the step 2.2, wherein the display detail is correspondingly reduced; otherwise, executing step 2.4;
if the current frame rate is greater than the maximum value, i.e. FR > FRmaxIf the value of the current Scale is not less than the minimum value S, the system computing resource is not fully utilizedminIf so, rendering by taking the new Scale value as the LOD Scale, and then executing the step 2.2, wherein the display detail is correspondingly improved; otherwise, step 2.4 is performed.
And 2.4, stopping adjusting the value of the Scale, simultaneously obtaining the display details of the current scene, and storing the corresponding numerical values of the display details into SC [ i ], wherein i is the number of the elements in the array SC, and i is (s-1) × 10, and the maximum value of i is N. Therefore, the frame rate can meet the requirement by setting the value of Scale to i for the scene with the current display details.
The first embodiment is as follows:
assuming that there are actually 10 vertices in the image of the current scene and the Scale value is 1, the frame rate can satisfy the index requirement. When a user moves a scene to a complex image, the content of the scene increases, the number of vertices in the current scene increases to 20, and the frame rate decreases accordingly. By fine-tuning the Scale value, it can be found that when the Scale value is increased to 2, the number of vertex points is correspondingly reduced to 10 in rendering detail, so that the frame rate can meet the index requirement. Since the actual number of vertices at this time is 20 and Scale is 2, the value of 10 th element (2-1) × 10 in the array SC [ i ] is set to 20.
The method for optimizing image display of dynamically adjusting LOD Scale, which adds a process of learning the corresponding relationship among the Scale value, the frame rate and the display details in advance, as shown in fig. 3, specifically includes the following steps:
step 3.1, setting the maximum value FR of the system frame rate dereferencing according to the index requirement of the system frame ratemaxAnd minimum value FRmin(ii) a Obtaining LOD Scale value currently adopted by the system as initial value s of Scale0Setting the maximum value S of ScalemaxAnd minimum value Smin. Initializing an array SC for storing a Scale value and display details corresponding to the Scale value, where the Scale value is such that the frame rate FR satisfies the condition FRmin≤fr≤FRmaxThe value of (a).
Step 3.2, obtaining the current frame rate FR of the system, if the current frame rate is larger than the maximum value or smaller than the minimum value, namely FR > FRmaxOr FR < FRminThen step 3.3 is executed; if the current frame rate is less than or equal to the maximum value and greater than or equal to the minimum value, FR is obtainedmin≤fr≤FRmaxThen step 3.7 is performed.
Step 3.3, obtaining the current display details of the current scene, and comparing the current display details with the elements in the array SC [ i ] one by one:
when the last element which is smaller than the current display detail and has the smallest difference with the current display detail is traversed, and meanwhile, the elements behind the element are not 0, the traversal is stopped, and the number of the element is recorded as n; if (N +1) < N, the Scale value s that should be currently set is

And as the value of the Scale value s, rendering by taking the new Scale value s as the LOD Scale, and executing the step 3.4.
Step 3.4, obtaining the current frame rate FR of the system, if the current frame rate is larger than the maximum value, namely FR > FRmaxThen step 3.5 is executed; if the current frame rate is less than the minimum value, i.e. FR < FRminThen step 3.6 is executed; if the current frame rate is less than or equal to the maximum value and greater than or equal to the minimum value, FR is obtainedmin≤fr≤FRmaxThen step 3.7 is performed.
Step 3.5, reducing the value of the Scale according to the set step, and if the value of the current Scale is not less than the minimum value SminRendering by taking the new Scale value s as LOD Scale, and then executing the step 3.4; otherwise, step 3.7 is performed.

And 3.7, storing the current display details as the ith (s-1) 10 elements into the array SC.
And 3.8, stopping adjustment and ending the process.
