Disclosed in the present application are a thumbnail display method and a related apparatus. The present application relates to the technical field of terminals. In the method, an electronic device can obtain a thumbnail by means of texture compression; in addition, the electronic device can acquire a texture file comprising certain parameters of an original image. Thus, the thumbnail displayed by the electronic device on the basis of the texture file can reflect the certain parameters of the original image.

The present invention relates to the technical field of WebGL radar volume rendering, and discloses a WebGL-based radar volume rendering performance optimization system. The method includes a texture acquisition and reconstruction module, a dynamic decomposition and clustering module, a metric calculation module, a strategy determination module, and a compression and rendering module. After structuring and reconstructing the original radar volume data, the method uses energy diffusion simulation to achieve dynamic hierarchical decomposition, and then performs adaptive clustering according to the texture feature correlation. By calculating the texture change intensity and spatial consistency metrics of each rendering subset, the global rendering load is evaluated, and then an adaptive texture compression strategy is determined. Finally, the structured texture field is lossily compressed and sent to the WebGL pipeline for rendering. This method enables the hierarchical structure to automatically conform to the data features and organizes the data according to the feature consistency, realizing the adaptive allocation and efficient compression of rendering resources, and improving the rendering efficiency and drawing quality in the Web environment.

The application provides a texture image compression method, device, equipment, storage medium and program product. The method comprises the following steps: obtaining a video memory budget value of an original texture image and a first pixel value of the original texture image; determining a texture compression parameter list of the original texture image based on the video memory budget value; the texture compression parameter list comprises at least one texture compression parameter corresponding to each image resolution in a plurality of image resolutions, and the texture compression parameter comprises a block size, a block number and a video memory overhead value; the video memory overhead value is less than or equal to the video memory budget value; obtaining a plurality of compressed texture data and reconstructed texture data after decoding each compressed texture data; determining a quality evaluation result of each reconstructed texture data based on the first pixel value and the reconstructed texture data; and determining target compressed texture data of the original texture image from the plurality of compressed texture data based on the quality evaluation result.
