Problems solved by technology

As a result, when there are too many vertices and graphics data in the rendered scene, the displayed frame rate will be lower than the target requirement; and when there are fewer vertices and graphics data in the rendered scene, the rendering performance will be excessive and the frame rate will be lower than the target. It is higher than the index requirement, but the excess performance cannot be used to improve rendering details, resulting in a waste of performance

Embodiment 1

[0064] Assuming that there are actually 10 vertices in the image of the current scene and the Scale value is 1, the frame rate can meet the index requirements. When the user moves the 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 also drops accordingly. By fine-tuning the value of Scale, it can be found that when the Scale value is increased to 2, the rendering details will be reduced to 10 vertices, so that the frame rate can meet the index requirements. Since the actual number of vertices is 20 at this time, and the Scale is 2, the value of the (2-1)×10=10th element in the array SC[i] is set to 20.

[0065] The image display optimization method of LODScale dynamically adjusts the process of pre-learning the corresponding relationship between Scale value, frame rate and display details, such as image 3 As shown, it specifically includes the following steps:

Abstract

The invention discloses an image display optimization method and device for dynamically adjusting LOD Scale. According to the obtained system performance and scene details, the LOD Scale in the rendering process is dynamically adjusted to ensure that the frame rate can meet the determined index requirements, that is, when the system is overburdened When it is high, the display details are exchanged for better performance, and when the system performance is excessive, the performance can be fully utilized to enhance the display details and improve the rendering quality.

Description

technical field [0001] The invention belongs to the technical field of computer graphics software development, and in particular relates to an image display optimization method and device for dynamically adjusting LOD Scale. Background technique [0002] LOD (Levels of Detail) is a level of detail model proposed by Clark scholars, which refers to the method of using different detail descriptions for different objects or different parts of objects in the scene. Specifically, LOD technology can determine the resource allocation for object rendering according to the position and importance of the object's model nodes in the display environment, reduce the number of faces and details of non-important objects, and thus obtain efficient rendering operations. The level of detail model can make it possible to observe the details of the model when the user's viewpoint is close to the object, and when the user's viewpoint gradually moves away from the model, the observed details are g...
