Fig. 1 is a schematic diagram of a file processing method according to an embodiment of the present invention. The illusion engine 110 and the editing tool library for special effects editing in fig. 1 may be installed as software configurations in the same electronic device or may be installed in different electronic devices. The electronic devices may be cell phones, desktop computers, and servers such as cloud servers.

The associated asset file 120 of the target special effect, which is various files required to be able to play or run the target special effect, may be acquired from the special effect editing project edited using the illusion engine 110. The associated asset file 120 for the target effect may be added to the editing tool library 120 as a target effect tool. Various special effects and associated asset files corresponding to the special effects are configured in the editing tool library 120, and the required special effects can be selected from the editing public library 120 to be imported into the illusion engine 110.

The above export, addition or import processes may be implemented by a storage space of the local electronic device, or may be implemented by transmission between the local electronic device and the server.

A file processing method according to another embodiment of the present invention will be described in detail with reference to fig. 2. The file processing method of fig. 2 includes:

s210: and analyzing each associated asset file of the target special effect in the special effect editing project to obtain the file dependency relationship of the target special effect in the special effect editing project.

S220: and determining path packing dependency relationships of each associated asset file based on the file dependency relationships.

S230: and based on the path packing dependency relationship, each associated asset file is derived from the special effect editing project.

In some examples, in order to achieve parsing of each associated asset file of the target effect in the effect editing project, a file dependency of the target effect in the effect editing project is obtained, an editing operation parameter related to the target effect in the effect editing project may be determined, and then, based on the editing operation parameter, the file dependency of the target effect in the effect editing project is determined, where the editing operation parameter indicates a file dependency variation caused by the editing operation. Therefore, through analyzing the associated asset file, the deep file dependency relationship is analyzed, and the path packing dependency relationship can be reliably determined.

In the process of editing operation of a user, the illusion causes the addition, association, deletion, modification and the like of the special effect asset elements based on corresponding editing operation parameters. Specific asset elements of the illusion engine include, but are not limited to, materials and textures, particle systems, animations and bones, blueprints and logic, lighting and shadows, sound effects, and the like.

In editing textures and textures, special effects editing involves modification or creation of textures and textures. Materials are used to define the appearance of the surface of an object, such as gloss, roughness, transparency, etc. Texture mapping provides color, detail, and other visual effects to the surface of an object. When editing special effects, new texture and texture files are modified or created to achieve specific visual effects.

In editing particle systems, particle systems in illusive engines are used to create various particle effects, such as flames, smoke, snow flakes, and the like. In the special effects editing process, particle system assets including particle emitters, particle materials, particle behaviors and the like need to be created or adjusted.

In editing animations and bones, special effects editing involves animation and bone modifications of characters or objects. For example, when adding a new action to a character, it is necessary to edit its skeletal structure and animation sequence. These modifications will affect the relevant animation files and skeleton files.

In editing blueprints and logic, special effects editing requires creation or modification of logic nodes in the blueprint system to achieve specific interactive and animation effects. These modifications may affect the blueprint asset file.

When the illumination and the shadow are edited, the illumination and the shadow in the scene need to be adjusted in order to achieve better special effect. This includes modifying light source attributes, adjusting illumination maps, using global illumination, and the like. These changes affect the scene file and the illumination map file.

In editing sound effects, special effects editing involves adding or modifying sound effect resources to match visual effects. This will result in a modification of the sound effect file.

That is, the above analysis of the related asset file obtains the change process of the asset file, and the current file dependency relationship is obtained by the change of the file dependency relationship indicated by the file change process such as the addition operation, the deletion operation, the modification operation, the related operation, and the like. In addition, each associated asset file is stored in a specific file directory of the special effect editing project based on the software configuration of the illusion engine, so that an initial path dependency relationship between the target special effect and the special effect editing project is formed.

In other examples, as an example of determining the path packaging dependency relationship of each associated asset file based on the file dependency relationship, an initial path dependency relationship of each associated asset file in the special effect editing project may be determined, and then the initial path dependency relationship is changed into the path packaging dependency relationship, so that the file dependency relationship of each associated asset file is consistent. That is, file dependency agreement of the respective associated asset files enables reliable rendering and presentation of the respective associated asset files after export, wherein the manner of presentation includes preview presentation and post-import project presentation. The path packing dependency relationship can separate each associated asset file from the special effect editing project, namely, decoupling between the target special effect and the special effect editing project is realized.

Further, as an example of changing the initial path dependency relationship into the path packing dependency relationship, the dependency hierarchy of the initial path dependency relationship can be simplified under the condition of ensuring the file dependency relationship, and the path packing dependency relationship can be obtained.

For example, FIG. 3A illustrates various asset files under the effect editing project, including a save path for the effect asset element and a save path for the editing operating parameters. The editing operation parameters indicate operation parameters of various special effects, such as operation parameters of adding operation, deleting operation, modifying operation and associating operation.

Further, fig. 3B shows the path packing dependency relationship obtained from the related asset file of the special effect 2 (example of the target special effect) separated from the special effect editing item of fig. 3A. In the path packing dependency relationship of fig. 3B, there are associated asset files related to the special effect 2, and there are no non-associated asset files of the special effect 2. The topology of the path-packed dependencies shown in FIG. 3B may be exported to a generic special effects tool library. If processing similar to the special effect editing item is performed in another special effect editing item (an item different from the special effect editing item) after the above-described special effect 2 is imported, the path dependency relationship shown in fig. 3C may be performed. It should be appreciated that fig. 3C is a path dependency based on the imported path packaging dependency, and if an effect edited in another effect editing project is not an imported effect, there still is an initial path dependency such as that shown in fig. 3A, it can be seen that after the export of the associated asset file of an effect is achieved, the import of an effect can be achieved through such as a general effect tool library or the like.

5. The method of claim 1, wherein deriving each associated asset file from the special effects editing project based on the path packaging dependencies comprises:

and exporting each associated asset file together with the path packing dependency relationship from the special effect editing project to a storage path of the universal special effect tool library, namely, the storage path packing dependency relationship is unchanged, and transplanting each associated asset file with the path packing dependency relationship from the storage path of the special effect editing project to the storage path of the universal special effect tool library.

Correspondingly, when the special effects are imported, each associated asset file of the target special effects is imported into a storage path of another editing special effect project from the universal special effect tool library. That is, the save path of another edited special effects item is different from the general special effects tool library, so that each associated asset file is transplanted again under the condition that the path packing dependency relationship is kept unchanged. Alternatively, each associated asset file may be transplanted again into the edited special effects item, but before the target special effects are exported, each associated asset file of the target special effects may be saved in a saving path of the edited special effects item in a manner that it is not directly portable, and after the target special effects item is imported, each associated asset file of the target special effects is saved again in the saving path of the edited special effects item, but the path dependency relationship changes.

In other examples, when each associated asset file is derived from the special effects editing project, the file processing method further comprises: generating a rendering order of each associated asset file based on the path packing dependency relationship; and rendering each associated asset file based on the rendering order to obtain a preview file of the target special effect. That is, the rendering order of each rendering task may be determined based on path packing dependencies that reflect the rendering tasks and scheduling relationships and dependencies.

Further, the file processing method may be performed by file processing software, which may be installed with a general purpose effect tool library. The special effects editing project may be configured by a fantasy engine. The document handling software and the illusion engine may be installed independently, the document handling software may perform import and export of various effects in the universal effects tool library, and fig. 2 actually provides at least one export scheme.

In one example, special effects editing items configured by the illusion engine may be imported into the file processing software, then, in an interface of the file processing software, the special effects editing items are selected, a list of file processing items is generated, and asset files are selected in the list for export, then, the file processing method of fig. 2 is executed.

The special effect editing item can be opened in the interface of the illusion engine to generate a file processing item list, and the file processing method of fig. 2 is executed when the asset file is selected to be exported in the list.

When the analysis of the asset files is performed, the asset dependency items can be analyzed according to a specific sequence, the topological graph of the asset path dependency relationship is calculated, an asset packing list comprising each associated asset file is constructed, each associated asset file is copied according to a new file path which is the path packing dependency relationship when the target special effects are imported, and the asset references of the special effects editing project are repaired.

In other examples, the rendered preview file, such as a preview video, may also be saved to a generic special effects tool.

Further, in parsing each associated asset file, for example, associations and dependencies between asset files including different types of files such as textures, models, textures, etc. may be analyzed by traversing each file in the special effects editing project. All relevant dependent items are then found by file format and path internal references.

After parsing the asset file dependencies, the dependencies may be represented using a graphical data structure (e.g., a tree graph).

Then, for each asset file, a new file path or name is generated as a path packing dependency according to custom file criteria (e.g., a reduced level or a deleted level). This may involve renaming, reorganizing the folder structure, and so on.

When the target special effect is imported into another special effect editing project, copying each associated asset file to a new path according to the path packing dependency relationship mapping relation. In this process, it may be necessary to process the files one by one and ensure that all dependent items are copied correctly.

After copying each associated asset file, the dependency references in each associated asset file need to be updated. This may be achieved by traversing the topology of the path-packing dependencies, replacing the topology of the initial path-dependency according to the topology of the path-packing dependencies. In this way, the derived individual associated asset file classes can be properly organized according to the new custom file criteria.

Fig. 4 is a block diagram showing a structure of a document processing apparatus according to another embodiment of the present invention. The document processing apparatus of fig. 4 includes:

the parsing module 410 parses each associated asset file of the target special effect in the special effect editing project to obtain the file dependency relationship of the target special effect in the special effect editing project.

The determining module 420 determines path packing dependencies of each associated asset file based on file dependencies.

The export module 430 exports each associated asset file from the special effects editing project based on the path packaging dependencies.

In other examples, the parsing module is specifically configured to: determining editing operation parameters related to the target special effects in the special effects editing project; and determining the file dependency relationship of the target special effect in the special effect editing project based on the editing operation parameters, wherein the editing operation parameters indicate file dependency variation caused by editing operation.

In other examples, the determination module is specifically configured to: determining initial path dependency relations of the associated asset files in the special effect editing project; and changing the initial path dependency relationship into a path packing dependency relationship, so that the file dependency relationship of each associated asset file is consistent.

In other examples, the determination module is specifically configured to: and under the condition of ensuring the file dependency relationship, simplifying the dependency hierarchy of the initial path dependency relationship to obtain a path packing dependency relationship.

In other examples, the file processing apparatus further comprises: and the importing module imports each associated asset file of the target special effect from the general special effect tool library into a storage path of another editing special effect item.

In other examples, the file processing device further includes a rendering module, when the related asset files are derived from the special effect editing project, the rendering module generates a rendering order of the related asset files based on the path packing dependency relationship, and renders the related asset files based on the rendering order to obtain a preview file of the target special effect.
