Description

Technical Field

[0001] The present invention relates to the technical field of three-dimensional modeling, and in particular to a three-dimensional scene loading method, a three-dimensional scene loading device, an electronic device and a computer-readable medium. Background Art

[0002] To display a 3D scene, an application can generate simple 3D models using code. However, most complex 3D models are drawn using specialized 3D software, exported as 3D files, and then loaded into the application for display. The 3D files exported by 3D software contain several 3D scenes, each of which contains several 3D models. Each 3D model includes data such as vertices, textures, and motions. If a material uses an image as its texture, the image data will also be included. 3D scenes typically consume a large amount of RAM, so managing this memory usage is crucial. Loading images used for textures requires a significant amount of RAM. For example, if an application loads a 1024x1024 pixel PNG file (32-bit image), each pixel uses 32 bits. The required RAM is calculated as 1024x1024x32 bits, which translates to a total of 4MB of RAM.

[0003] When 3D software draws a 3D scene, if different 3D models within the software reuse the same image as a texture, the same image will ultimately be referenced, rather than loaded multiple times. When the 3D file is exported, only one image will be included, without duplicates. When the software loads this 3D file, since the texture data all points to the same image, only the data for that single image will be loaded. However, this approach only works for 3D scenes displaying fixed content and is not suitable for scenarios where the application needs to combine different models to create different 3D scenes based on specific circumstances.

[0004] This approach addresses situations where applications need to combine different models to create different 3D scenes based on specific circumstances. The typical approach is to create each 3D model separately and dynamically load and display it based on the application's needs. However, when creating separate 3D models, each with its own image, duplicate images may be loaded within a single 3D scene. For example, if two 3D models are exported separately and the 3D software uses the same image as its texture, each exported model file will contain the image data. When the application loads these two models, it will need to load the data for both images. Obviously, the two images loaded by the application are essentially the same, resulting in duplicate images being loaded during the 3D scene loading process. This not only increases data transmission volume but also increases the memory usage during the 3D scene display. Summary of the Invention

[0087] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0088] Reference Figure 1 , shows a flowchart of a three-dimensional scene loading method provided in an embodiment of the present invention, which may specifically include the following steps:

[0089] Step 101: Obtain at least one 3D model file required for loading a first 3D scene;

[0090] In the embodiment of the present invention, a 3D scene is generated by loading a 3D model file. Therefore, before loading the 3D scene, the 3D model file can be obtained. A 3D scene can include at least one 3D model. Therefore, loading a 3D scene can obtain at least one 3D model file.

[0091] Specifically, for loading the first 3D scene, a 3D model file list required for loading the first 3D scene may be obtained first, and then all 3D model files in the 3D model file list may be loaded. These 3D model files may be derived from 3D models drawn by 3D software.

[0092] Step 102: merging the three-dimensional model files to obtain a three-dimensional model file set;

[0093] After obtaining the 3D model files required to load the first 3D scene, these 3D model files can be preliminarily aggregated, that is, the obtained 3D model files are merged to obtain a complete 3D model file set so that the data of the 3D model files can be uniformly processed next.

[0094] Step 103: performing a first image deduplication process on the 3D model file set to obtain a target 3D model file set;

[0095] The merged 3D model file collection may include duplicate images, which increases the data transmission volume and causes invalid usage of running memory when loading these duplicate images when loading the 3D scene. Therefore, before loading the 3D scene, the 3D model file collection can be subjected to a first image deduplication process, so that each image in the target 3D model file collection obtained after the deduplication process is unique, thereby eliminating the need to load invalid duplicate images when loading the 3D scene.

[0096] Step 104: load the target 3D model file set and display the first 3D scene.

[0097] After obtaining the deduplicated target 3D model file set, you can load the target 3D model file set to generate and display the first 3D scene in the application. Because the deduplicated target 3D model file set is used, each loaded image is unique and valid, reducing data transmission and conserving runtime memory space during display.

[0098] In an embodiment of the present invention, at least one 3D model file required for loading a first 3D scene is obtained, the 3D model files are merged to obtain a 3D model file set, a first image deduplication process is performed on the 3D model file set to obtain a target 3D model file set, the target 3D model file set is loaded, and the first 3D scene is displayed. Using the 3D scene loading method of the present invention, duplicate determination and deduplication processing can be performed on the images in all 3D model files before loading and displaying the 3D scene, so that no duplicate images are included in the target 3D model file set ultimately used for loading, thereby reducing the amount of data transmitted when loading the 3D scene and saving runtime memory.

[0099] Reference Figure 2 , shows a flowchart of another three-dimensional scene loading method provided in an embodiment of the present invention, which may specifically include the following steps:

[0100] Step 201: Obtain at least one 3D model file required for loading a first 3D scene;

[0101] Step 202: merging the three-dimensional model files to obtain a three-dimensional model file set;

[0102] Step 203: determining whether there is at least one set of duplicate images in the three-dimensional model file set; each set of duplicate images includes at least two images;

[0103] Before deduplication is performed on the merged 3D model file set, it may be determined whether there is at least one set of duplicate images in the 3D model file set, so as to determine whether further deduplication of the images is required.

[0104] The three-dimensional model file set may include at least one group of repeated images; each group of repeated images may include at least two images.

[0105] In one embodiment of the present invention, the step of determining whether there is at least one set of duplicate images in the three-dimensional model file set includes:

[0106] S11, calculating a summary value of each image in the three-dimensional model file set;

[0107] S12, comparing the digest values; the pictures with the same digest value are in the same group of repeated pictures; the same group of repeated pictures includes at least two pictures;

[0108] S13, if there are at least two identical summary values, determining that there is at least one set of duplicate images in the three-dimensional model file set;

[0109] S14: If all the summary values are different, it is determined that there is no at least one set of duplicate images in the three-dimensional model file set.

[0110] In an embodiment of the present invention, a summary algorithm can be used to calculate the summary value of each image, and images with the same summary value can be determined as duplicate images. Therefore, to determine duplicate images, the summary value of each image in the three-dimensional model file set can be calculated first, and then the summary values of these images can be further compared to determine duplicate images.

[0111] Specifically, if there are at least two identical summary values, it can be considered that at least two images are duplicated, and it can be determined that there is at least one set of duplicate images in the 3D model file set; if all the summary values are different, it can be considered that all the images are completely different, and it can be determined that there is no at least one set of duplicate images in the 3D model file set.

[0112] Step 204: If there is at least one set of duplicate images in the 3D model file set, delete each set of duplicate images until only one remains, and obtain a unique image corresponding to each set of duplicate images;

[0113] After judging the duplicate images, if it is determined that there are no duplicate images in the 3D model file set, the 3D model file set is directly loaded to obtain the first 3D scene; if it is determined that there is at least one group of duplicate images in the 3D model file set, the duplicate images are deduplicated, and each group of duplicate images is deleted until only one is left to obtain the corresponding unique image of each group of duplicate images.

[0114] Step 205 : Point all deleted pictures in each group of duplicate pictures to reference the corresponding unique picture to obtain the target three-dimensional model file set.

[0115] These deleted images originally belonged to separate 3D model files and were the images required to construct the 3D model corresponding to the separate 3D model file. Therefore, in order to ensure that the 3D model finally loaded is correct, after deleting them, all deleted images in each group of duplicate images can be pointed to reference the corresponding unique image to obtain the target 3D model file set, so that the 3D scene obtained by loading the target 3D model file set is exactly the same as the 3D scene obtained by loading all the original separate 3D model files.

[0116] In one embodiment of the present invention, the step of referencing all images deleted from each group of duplicate images to the corresponding unique image to obtain the target three-dimensional model file set includes:

[0117] S21, adding a picture redirection mark value corresponding to the corresponding unique picture to all pictures deleted from each group of duplicate pictures, to obtain the target three-dimensional model file set;

[0118] Redirecting deleted images can be achieved by adding image redirection tags corresponding to the unique images to these images. The target 3D model file set obtained after redirection can be loaded to obtain the correct 3D scene. The image redirection tag value can be the digest value of the corresponding unique image.

[0119] Step 206: load the target 3D model file set and display the first 3D scene.

[0120] In one embodiment of the present invention, the step of loading the target 3D model file set and displaying the first 3D scene includes:

[0121] S31, extracting data from the target three-dimensional model file set;

[0122] S32, determining whether the data includes the image redirection flag value;

[0123] S33: If the picture redirection mark value is included, all pictures deleted from each group of repeated pictures are loaded as the corresponding unique pictures according to the picture redirection mark value, and the first three-dimensional scene is displayed.

[0124] After obtaining the redirected target 3D model file set, the target 3D model file set may be loaded, so that the first 3D scene may be generated and displayed in the application.

[0125] Specifically, first, the data in the target three-dimensional model file set can be extracted to determine whether the data contains an image redirection mark value. If the data contains an image redirection mark value, all images deleted from each group of duplicate images are loaded as corresponding unique images according to the image redirection mark value to display the first three-dimensional scene.

[0126] In one embodiment of the present invention, the method further comprises:

[0127] S41, dynamically loading a new 3D model file during the display of the first 3D scene;

[0128] When the first three-dimensional scene is displayed, there may be a situation where one wants to add a three-dimensional model to the first three-dimensional scene, thereby obtaining a second three-dimensional scene including the first three-dimensional scene and the new three-dimensional model.

[0129] Therefore, when displaying the first 3D scene, a new 3D model file can be dynamically selected and loaded for display, so as to update the 3D scene displayed in the application.

[0130] S42, performing a second image deduplication process on the new 3D model file to obtain a target 3D model file;

[0131] The new 3D model file may also include duplicate images. These duplicate images may be identical to existing images in the first 3D scene, or they may be duplicate images that exist only in the new 3D model file. For duplicate images that exist only in the new 3D model file, the same image deduplication method as used in the first 3D scene, i.e., the first image deduplication process, may be used.

[0132] In the case where there are pictures that are identical to repeated pictures of the first three-dimensional scene, a second picture deduplication process may be performed on the new three-dimensional model file to obtain a target three-dimensional model file, thereby achieving deduplication of the repeated pictures.

[0133] In one embodiment of the present invention, the step of performing a second image deduplication process on the new three-dimensional model file to obtain a target three-dimensional model file includes:

[0134] S51, detecting and loading the image in the new three-dimensional model file;

[0135] S52, determining whether there are pictures in the new 3D model file that are identical to all pictures in the first 3D scene;

[0136] When performing deduplication processing on a new 3D model file, it is possible to first determine whether there are duplicate images in the new 3D model file. Specifically, the images in the new 3D model file can be detected and loaded first, and then it is determined whether there are images in the new 3D model file that are identical to the corresponding unique image.

[0137] In one embodiment of the present invention, the step of determining whether the new three-dimensional model file contains pictures that are identical to all pictures in the first three-dimensional scene includes:

[0138] S61, calculating the summary value of the picture in the new three-dimensional model file;

[0139] S62, comparing the summary value of the picture in the new 3D model file with the summary values of all pictures in the first 3D scene;

[0140] S63: If there is a picture with the same digest value as all the pictures of the first three-dimensional scene, determining that there is a picture in the new three-dimensional model file that is the same as all the pictures of the first three-dimensional scene;

[0141] S64: If there is no picture with the same digest value as all the pictures of the first three-dimensional scene, determine that there is no picture in the new three-dimensional model file that is the same as all the pictures of the first three-dimensional scene.

[0142] To determine whether there are duplicate images in the new three-dimensional model file, you can first calculate the summary values of all images in the new three-dimensional model file, and then compare the summary values of the images in the new three-dimensional model file with the summary values of the images in the first three-dimensional scene. If there is a summary value that is the same as the summary value of the image in the first three-dimensional scene, it is determined that there is a picture in the new three-dimensional model file that is the same as the picture in the first three-dimensional scene. If there is no summary value that is the same as the summary value of the image in the first three-dimensional scene, it is determined that there is no picture in the new three-dimensional model file that is the same as the picture in the first three-dimensional scene.

[0143] S53: If the new 3D model file contains images identical to all images in the first 3D scene, releasing the images in the new 3D model file that are duplicated with the images in the first 3D scene, and pointing the released images to the identical images in the loaded first 3D scene, thereby obtaining a target 3D model file.

[0144] S54: If the new 3D model file does not contain any pictures identical to all the pictures in the first 3D scene, retain all the pictures in the new 3D model file and use the new 3D model file as the target 3D model file.

[0145] After performing duplicate image judgment on the new 3D model file, if it is determined that the new 3D model file contains an image that is identical to the image in the first 3D scene, the image in the new 3D model file that is identical to the image in the first 3D scene is released, and the released image is pointed to the same image in the loaded first 3D scene to obtain the target 3D model file; if it is determined that the new 3D model file does not contain an image that is identical to the image in the first 3D scene, all images in the new 3D model file are retained, and the new 3D model file can be directly used as the target 3D model file.

[0146] S43, loading the target 3D model file and displaying the second 3D scene;

[0147] If you want to display the combination of the new 3D model and the first 3D scene, you can load the target 3D model file and the target 3D model file collection at the same time. At this time, you can determine whether to update the first 3D scene displayed in the application to a 3D scene that includes the first 3D scene, that is, the second 3D scene.

[0148] Specifically, the target 3D model file and the target 3D model file set may be merged to obtain a new 3D model file set, and then the new 3D model file set may be loaded, so that the second 3D scene may be displayed in the application.

[0149] As an example of the present invention, refer to Figure 3, shows a schematic diagram of a three-dimensional equipment room loading process for texture image deduplication provided in an embodiment of the present invention.

[0150] In an actual 3D scenario, an equipment room contains 24 different types of cabinets. The texture images used for their exteriors are identical, but the internal equipment boards are different. Through cache optimization, only the duplicate exterior cabinet texture image is calculated, saving the memory used by the 23 duplicate images. Furthermore, some of the internal equipment boards of each cabinet are of the same type, and the texture images of these boards can also be cached and optimized, further saving memory used by duplicate images.

[0151] The application loads and displays a 3D equipment room containing 24 types of cabinets, all using the same exterior texture image. When loading, the application reads the data from each of the 24 model files, applies a digest algorithm to the texture images, compares and detects duplicate textures, retains only one image, removes the duplicate data, redirects to that image, and then merges the data into a new 3D model file based on the scene. The new file then loads and displays the 3D scene. This process saves data transmission and runtime memory space for 23 images.

[0152] As another example of the present invention, refer to Figure 4 , shows a schematic diagram of a new cabinet model loading process for texture image deduplication provided in an embodiment of the present invention.

[0153] To add a cabinet of a different type (e.g., cabinet 25), the application first reads the model file and runs a digest algorithm on the texture image. After comparing, it detects that the texture image for the exterior cabinet already exists in the 3D scene. The application then deletes the image data and uses the digest value as the image redirection tag. The application then loads the 3D model data and, based on the image redirection tag, redirects the exterior cabinet texture image to the existing exterior cabinet image. This process saves the data transmission and runtime memory of one image.

[0154] In an embodiment of the present invention, at least one 3D model file required for loading a first 3D scene is obtained, the 3D model files are merged to obtain a 3D model file set, a first image deduplication process is performed on the 3D model file set to obtain a target 3D model file set, the target 3D model file set is loaded, and the first 3D scene is displayed. Using the 3D scene loading method of the present invention, duplicate determination and deduplication processing can be performed on the images in all 3D model files before loading and displaying the 3D scene, so that no duplicate images are included in the target 3D model file set ultimately used for loading, thereby reducing the amount of data transmitted when loading the 3D scene and saving runtime memory.
