Description

Technical Field

[0001] The present invention relates to the technical field of maya animation production, and particularly relates to a distributed export method for animation models in maya. Background Art

[0002] In the traditional animation production process, the model is generally exported in the Alembic file format to export the animation model, generating a file with the extension.abc, so this export method is also called ABC. The animation model can be read and produced in the subsequent production process only after being exported as an independent file. Therefore, the animation model export link is of great significance in animation production.

[0003] When exporting the animation model in the ABC method, only one task can be exported at a time, and all data of the animation model need to be recorded when exporting the animation model. It cannot be split and exported in a distributed manner. At the same time, when the actions of the animation model change within a certain period of time, the frames of the changed animation model cannot be exported separately, and all frames of the animation model need to be exported again. It lacks flexibility and has great limitations. At the same time, it causes a long export time and low efficiency.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a distributed export method, device and medium for animation models in maya, which can realize the distributed export of animation models, effectively improve the export efficiency of animation models, and has strong flexibility in the animation production process, thereby solving the above technical problems existing in the prior art.

[0009] Step 2, determine the export frame range of the animation model;

[0010] Step 3, according to the export frame range determined in Step 2, the calculation amount of the export task and the number of sub-servers, the main server evenly divides the export task into multiple split export frame tasks, and distributes each split export frame task to a sub-server. Each sub-server performs the export processing of the corresponding split export frame task simultaneously at the same time according to the attribute of the animation model determined in Step 1, and respectively obtains each sequence sub-file that only records the position information of the animation model without recording the original information;

[0011] Step 4: Use the total file stored in the total server to record the storage path information and corresponding playback rules of each sequence sub-file of each sub-server, and use the total file as the final exported file.

[0016] Compared with the prior art, the distributed export method, device and medium for animation models in maya provided by the present invention have the following beneficial effects:

[0017] Since the distributed calculation is used to export the animation model according to the determined export frame range, the calculation amount of the export task and the number of sub-servers, the export efficiency of the animation model can be effectively improved, and the flexibility of the animation production process is strong.

[0028] As Figure 1 shown, an embodiment of the present invention provides a distributed export method for an animation model in Maya, including:

[0029] Step 1, determine the attributes of the animation model to be exported in the animation production software Maya, where the attributes are one of a rigid model and a non-rigid model;

[0030] Step 2, determine the export frame range of the animation model;

[0031] Step 3, according to the export frame range determined in Step 2, the calculation amount of the export task, and the number of sub-servers, the master server evenly divides the export task into multiple split export frame tasks, and distributes each split export frame task to a sub-server. Each sub-server performs the export processing of the corresponding split export frame task simultaneously at the same time according to the attributes of the animation model determined in Step 1, and respectively obtains each sequence sub-file that only records the position information of the animation model without recording the original information;

[0032] Step 4, use the master file stored in the master server to record the storage path information and corresponding playback rules of each sequence sub-file of each sub-server, and use the master file as the final export file.

[0033] Preferably, in the above export method, the animation model with the attribute of a rigid model refers to a model that will not undergo overall deformation but only spatial position changes;

[0034] The animation model with the attribute of a non-rigid model refers to a model that will undergo deformation.

[0035] Preferably, in the above export method, in Step 4, if the attribute of the animation model determined in Step 1 is a rigid model, the export operation method of the corresponding sub-server is:

[0036] Record the position change information of the entire rigid model and export it.

[0037] Preferably, in the above export method, in Step 4, if the attribute of the animation model determined in Step 1 is a non-rigid model, the export operation method of the corresponding sub-server is:

[0038] Record the position information of each point of each frame of the entire non-rigid model, that is, the deformation information, and export it.

[0039] Preferably, in the above export method, in step 4, each sequence sub-file that only records the position information of the animation model without recording the original information is a USD format file.

[0040] Preferably, in the above export method, in step 5, the total file stored in the total server is a USD format file.

[0041] Preferably, in the above export method, the export frame range of the animation model refers to selecting a specific range of frames from the animation sequence of the animation model and extracting this range of frames from the working environment of the animation production software maya.

[0042] An embodiment of the present invention further provides a processing device, including:

[0043] At least one memory for storing one or more programs;

[0044] At least one processor capable of executing the one or more programs stored in the memory. When the one or more programs are executed by the processor, the processor can implement the above method.

[0045] An embodiment of the present invention further provides a readable storage medium storing a computer program that can implement the above method when executed by a processor.

[0046] In summary, in the distributed export method of the embodiment of the present invention, the export frame task of an animation model is evenly divided into multiple split export frame tasks according to the calculation amount. The total server distributes each split export frame task to each sub-server for export frame task processing, and the corresponding sequence sub-files obtained by export are all in USD format files. The storage path information and corresponding playback rules of each sequence sub-file are recorded in the total file, and the total server uses the total file as the final export file. Since the exported USD format file does not record the original data but only records the actually changed data, it has the advantage of small storage space occupation. The export method of the present invention is based on the USD framework and uses a distributed computing method to export the animation model, which can effectively improve the export efficiency of the animation model, has strong flexibility in the animation production process, and well solves the problems of insufficient flexibility, large limitations, long export time, and low efficiency existing in the existing method of exporting animation models based on the traditional Alembic file format.

[0047] In order to more clearly show the technical solutions provided by the present invention and the technical effects produced, the following uses specific embodiments to describe in detail the solutions provided by the embodiments of the present invention.

[0048] Example 1

[0049] like Figure 1 As shown, this embodiment provides a distributed export method for animation models in Maya, including:

[0050] Step 1, determining the attribute of the animation model to be exported in the animation production software Maya, wherein the attribute is one of a rigid model and a non-rigid model;

[0051] Step 2, determining the export frame range of the animation model;

[0052] Step 3: According to the export frame range determined in step 2, the computational amount of the export task and the number of sub-servers, the main server evenly divides the export task into multiple split export frame tasks, and assigns each split export frame task to a sub-server. Each sub-server simultaneously performs the export processing of the corresponding split export frame task at the same time according to the attributes of the animation model determined in step 1, and obtains each sequence sub-file that only records the position information of the animation model but does not record the original information;

[0053] Step 4: Use the master file stored in the master server to record the storage path information and corresponding playback rules of each sequence sub-file of each sub-server, and use the master file as the final export file.

[0054] In the animation software Maya, the rigid model refers to the model that will not deform as a whole but only change its spatial position, such as the animation models of pens, balls, screens, etc. The deformable models are called non-rigid models, such as the animation models of people and fingers. Determine the export frame range of the animation model to be exported. Exporting frames means selecting specific frames or a range of frames from the animation sequence and extracting them from the working environment of the animation software, just like capturing certain scenes from a movie and saving them.

[0055] Each animation model has many points, and these points have unique three-dimensional coordinates in the virtual space. If a certain point of an animation model is set as the reference point and the precise point is used as the origin, then other points have a relative three-dimensional coordinate based on the origin. The coordinates of these points record the position information, normal information, UV information, etc. of the animation model.

[0056] The export task is subdivided into multiple subtasks according to the selected export frame range. Specifically, on the main server side, the export task is evenly divided into multiple split export frame tasks according to the computational workload, and each split export frame task is assigned to a sub-server. Each sub-server processes the split export frame task simultaneously within the same time to obtain the corresponding sequence sub-files, greatly accelerating the export rate of the entire animation model. For each of the exported sequence sub-files, they can be exported in the form of a total file reference, which is concise and clear, and it is more convenient to call animations within a specific frame rate range for each exported frame, facilitating subsequent animation production.

[0057] This way of exporting the total file does not record the original information (normal information, uv information, etc.), but only records the position information of the animation model. Since before exporting the animation model, a rigid and non-rigid property judgment will be made on the animation model, and different export modes will be selected according to the rigid and non-rigid properties of the model, and then the operation of exporting the animation model will be carried out. During the export process, the system will export the necessary data according to the type of the selected model. If it is a rigid model, only the position information of several vertices that determine the shape of the rigid model for each frame needs to be recorded, that is, the position change information of the entire rigid model is recorded and exported; if it is a non-rigid model, the position information of each point for each frame needs to be recorded, that is, the information of the model deformation is recorded and exported.

[0058] Through the above-mentioned distributed computing method, the work of exporting by a traditional single server is distributed to multiple sub-servers, and the efficiency is increased by several times, greatly shortening the export time and improving the export efficiency; at the same time, since only the position information data that actually changes needs to be output and the original information does not need to be recorded, the final exported file size is greatly reduced, realizing the effective utilization of resources; for the animation production link, due to the distributed export and the way of using a total file to reference each sequence sub-file, for the adjustment of actions during the animation production process, only the frames within a certain time period need to be re-exported, instead of re-exporting all frames as in the past, which is time-consuming and laborious. Only the frames within the time period where deformation occurs need to be exported, thus saving a lot of time.

[0059] The logic of distributed output is to evenly allocate the computational workload of the total export task to each sub-server. Taking an animation character with 1000 frames as an example, if 100 sub-servers (i.e., 100 computers) are used for parallel processing, each sub-server only needs to be responsible for the export work of 10 frames. Compared with the traditional way where only one server can export one file, the efficiency is doubled, which depends on the number of sub-servers.

[0060] The overall file reference actually refers to a single overall file that references a large number of exported sub-files. The overall file is essentially a path storage information and rule record file. It records the path storage information of each sub-file and the rules for activating certain frames at a certain time point and for how long. Therefore, this overall file does not take up much memory and is automatically generated after the export task is completed. This file is generated in accordance with the USD file specification, which is common knowledge in the industry and will not be elaborated further.

[0061] The distributed export method of this embodiment has at least the following advantages:

[0062] (1) Improve export efficiency: Compared with the traditional ABC export method, when using the distributed method to export an animation model to the USD format and splitting the task among multiple servers to work simultaneously, the efficiency is greatly improved.

[0063] (2) Save storage resources: The amount of data recorded by this method is significantly less than that recorded by the traditional ABC method, saving hard disk space and resources.

[0064] (3) Facilitate subsequent animation production and have high flexibility in use: In this method, when a certain animation model changes within a certain period of time, it is not necessary to re-export the entire model. Instead, only the animation model within a specific time period needs to be re-exported. Compared with the traditional method, it is more flexible, and at the same time, it shortens the export time by a large amount, which also provides convenience for subsequent production processes.

[0065] (4) Adopt the method of using the overall file to reference sub-files, and the overall file is a file that records the storage path information and playback rules of sub-files. Therefore, in actual applications, specific animation actions at specific times can be arbitrarily specified and called for production, which provides convenience for downstream production.

[0066] As mentioned above, the above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims. The information disclosed in the background art part of this article is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those skilled in the art.
