It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
The invention will be further explained by the description of the embodiments with reference to the drawings.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating a method and a system for automatically optimizing a file based on Maya according to the present invention. The method comprises the following steps:
s100, when a file optimization instruction is received, detecting the current stage of a file, wherein the current stage of the file comprises an asset stage, an animation stage and a rendering stage.
Specifically, the invention automatically optimizes the file in each process of file generation and use, and the invention avoids the condition that different producers can not unify the effect. Particularly, the investment of hardware resources in the subsequent stage and the time consumption for rendering the graph are remarkably reduced. In this embodiment, an optimization option may be set in advance in the Maya system, and when the optimization option is selected, a corresponding file optimization instruction is generated, that is, the optimization instruction represents an automatic optimization process on the file. Correspondingly, when a file optimization instruction is received, the current stage of the file is detected, and the current stage of the file comprises an asset stage, an animation stage and a rendering stage. Therefore, different optimization schemes are corresponding to different stages corresponding to the current file.
In an implementation manner of this embodiment, when the file optimization instruction is received, before the step of detecting the current stage of the file, the method further includes:
s10, creating a first structural standard for the asset stage of the file in advance, and creating a second structural standard for the animation stage of the file.
Specifically, a first structural standard is created for the asset stage of the file, and the first structural standard comprises information such as hierarchical relationship and initialization attribute in the file, so that background content (such as a skeleton system and a lattice system) which is not required to be displayed can be hidden, and detection and optimization of upstream and downstream matched tools can be facilitated. Correspondingly, a second structural standard is created in the animation stage of the file, and the second structural standard comprises the creation of a unified structural standard (such as file inner-layer level relation, display layer management and the like) so as to facilitate detection and optimization of upstream and downstream matched tools. It should be noted that the animation phase specification standard details are different from the asset standard.
S200, performing corresponding optimization operation on the file according to the current stage of the file to realize automatic optimization of the file.
Specifically, the method and the device perform corresponding optimization operation on the file according to the stage of the file, thereby meeting different optimization requirements of each stage and avoiding invalid consumption. Correspondingly, in an implementation manner of this embodiment, performing the corresponding optimization operation on the file according to the current stage of the file specifically includes:
s201, when the file is in the asset stage, automatically clearing the history information and redundant nodes of the file.
Specifically, each operation process in the file animation production can be recorded, and the repair and adjustment of a producer can be facilitated according to the record. However, the excessive operation history may increase the calculation amount, so that the animation phase or the rendering phase is not limited. After the final effect is determined, the historical operation records need to be cleared without affecting the final effect, thereby reducing unnecessary computation consumption. It should be noted that most of the historical information removed by the present invention cannot be found by human, but the automatic optimization process of the present invention can complete the cleaning.
Further, under the condition that the asset production is not completed in one step, namely whether the asset is produced for the first time or is produced for the repair, unnecessary draft deletion exists, manual deletion is likely to be incomplete, and residual useless nodes exist. These residual nodes, not only affect the asset size, but also increase the computational load of the asset in the animation. Therefore, after the final effect is determined, the historical operation records need to be cleared without influencing the final effect, so that unnecessary calculation consumption is reduced. It should be noted that most of the redundant nodes eliminated by the present invention cannot be found by manual search, and the automatic optimization processing of the present invention can complete the cleaning.
Furthermore, CG production software is not universal, and additional development of supporting functions is required to record some information and transmit the information to downstream links. For example, the subdivision level information, rendering attributes and the like of the model directly influence rendering production, but the information is not a good choice when being recorded in a file, and especially in CG production such cross-platform production (cross-platform production, a same project is produced by using multiple kinds of software, but files among different production software cannot be 100% compatible, and are imported into other software, and general information of an original file main body can be retained, but unique information of the original software cannot be retained). And exporting to the outside, and then developing and distributing a socket between different software to finish information transmission so as to make up for the defect of cross-platform manufacturing.
In an implementation manner of this embodiment, the method for automatically optimizing a file based on Maya further includes:
s20, generating versions with different sizes for the texture calling maps in advance so that the files can be called at different stages.
Specifically, with the development of CG animation industry, the final picture quality requirement is higher and higher, the content of picture constituent elements is more and more complex, and the computer development cannot keep up with the requirements of complex scenes, and if only high-precision assets are used in the animation stage, it is likely that the computer is stuck, which directly affects the production efficiency. The animation phase thus uses low precision assets for animation, and the rendering phase uses high precision assets. If the high-precision assets and the low-precision assets are all handed to the manufacturer to be manufactured, the workload is doubled. Therefore, the invention develops a multi-precision automatic generation tool, and automatically generates the low model by analyzing the topological structure of the object and using methods of simplifying wiring, merging and the like to finish the automatic generation of the low-precision version of a part of assets. For example, main style parameters required by different projects, such as projects of a submarine scene, which need to improve the intensity of highlight, can be set according to the final picture effect; from the effect requirement perspective, movies require a higher level of precision effect, model map source files all require an extremely high size (e.g., 8K), whereas tv show items require somewhat less display effect, and model map source files only require a high size.
Meanwhile, in the aspect of material, versions with different sizes are generated by the mapping called by the material and are called by different stages, if the low-precision mapping is used in the animation stage, the calculation consumption is reduced, and the manufacturing efficiency is improved, and if the mapping with different precisions is called by the rendering stage according to different conditions, if the low-precision mapping is called by the long-distance asset, the high-precision mapping is called by the short-distance asset. On the premise of ensuring the picture quality, the method is flexibly called, thereby achieving the purpose of saving resources.
In an implementation manner of this embodiment, performing the corresponding optimization operation on the file according to the current stage of the file specifically includes:
s202, when the file is in the animation stage at present, reading the frame range of the file from a preset database, and setting the frame range as the frame range of the file.
Specifically, in the prior art, after the animation file is opened, the frame range is usually set manually according to the document description, which is time-consuming, labor-consuming and error-prone. However, in this embodiment, by setting the corresponding frame range information in the preset database, the animation file can automatically read the database, call the relevant information in the director's storyboard, and directly set the frame range. Therefore, the problem that manual setting is easy to make mistakes is avoided, time is saved, and working efficiency is improved.
In an implementation manner of this embodiment, the method for automatically optimizing a file based on Maya further includes:
s203, when an uploading instruction of the file is received, automatically analyzing whether the version of the current file is correct or not;
and S204, if the current file version is incorrect, obtaining the correct version of the file and setting the correct version as the version.
In particular, since the CG project is a large project in which hundreds of persons participate, the increase in the number of persons is accompanied by an increase in the difficulty of management. And more or less mistakes are made by everyone, and the calling of the asset versions is wrong and more frequent. It is common practice to find a version call error and notify the producer to manually open a file to change asset versions, however, this process is time consuming and may also be subject to errors due to the producer's negligence.
In the invention, the automatic asset correcting tool is created in advance and integrated in the uploading process, so that whether the automatically called version is correct or not can be analyzed through the automatic asset correcting tool, if the automatically called version is incorrect, the correct version is obtained directly through an algorithm and is directly replaced by the correct version, the time is saved, the secondary problem is avoided, and the animation production efficiency is greatly improved.
In an implementation manner of this embodiment, the method for automatically optimizing a file based on Maya further includes:
and S205, extracting displacement and rotation information of the camera in the world coordinate axis, and providing the extracted data information for a downstream link to call.
In particular, CG production involves cross-platform production, and camera animation needs to be circulated through cross-platform data. The camera animation in the animation stage is often finished in a complex mode, and manual operation derivation is likely to cause problems and results are incorrect. Correspondingly, the invention also develops an automatic baking and exporting tool of the camera, so that the complex camera animation in the animation file can be ignored, and the displacement and rotation information of the camera under the world coordinate axis can be directly extracted by a secondary baking method. Objects in the CG software have not only spatial information but also an upper and lower hierarchical relationship. When the B object is at the lower level of the a object, the spatial information of the B object is relative coordinate information under the a-space system. If the information of B is to be transmitted, pure spatial information, namely spatial information of B under the world coordinate axis, is obtained. If only the local spatial information of B is transmitted, the position in the third-party software is wrong. The extracted world coordinate axis information of the B object is the pure information of the B object, and then the extracted world coordinate axis information is output as intermediate data, and the intermediate data can be called for providing downstream links.
In an implementation manner of this embodiment, the performing, according to the current stage of the file, the corresponding optimization operation on the file specifically includes:
s206, when the file is in a rendering stage at present, splitting the shots of the same scene in the atmosphere at the same time into templates of different units;
and S207, analyzing the same batch of shot files, automatically separating role assets and scene assets, automatically calling rendering style parameters applicable to the template and setting the rendering style parameters as files, and automatically loading lighting information applicable to the template to construct files used in a rendering stage.
In particular, in industrial production, the nature of the increase in efficiency comes from automated pipelining. With the mold, the automatic assembly line operation can be realized. Similarly, CG production is performed by a manual operation, and when the population quality producing ability is uneven, it is absolutely inefficient. The CG manufacturing productivity can be liberated only by the assembly line manufacturing in the CG manufacturing.
In the invention, the specification standards are unified in the upstream links, so that a foundation is laid for CG production line production. However, CG is a complex assembly of multiple parts, the unit of which is the lens, according to industry standards. And each lens cannot be manufactured into a mould, so that the efficiency is not different from that of manual manufacturing. By analyzing the commonality of the projects, the shots of the same scene in the same time atmosphere (such as in the morning) are split into different units, namely, the molds of the template-CG boundary.
Correspondingly, the invention takes the template with scene time atmosphere as a unit, analyzes the same batch of shot files on the basis of the template, automatically separates role assets and scene assets, automatically calls rendering style parameters applicable to the template and sets the rendering style parameters to the files, and simultaneously automatically loads lighting information applicable to the template to construct the files used in the rendering stage. Correspondingly, the invention also customizes different template groups for different projects, and the template groups are basically unchanged and are adjusted in details. Therefore, the method is very convenient for development and customization and batch manufacturing, and directly and greatly improves the manufacturing efficiency.
It should be noted that, the above optimization adjustments all have log records, and each optimization stage has a start prompt and an end prompt, so that the abnormal condition is well documented.
The present invention also provides a computer-readable storage medium storing one or more programs, which are executable by one or more processors, to implement the steps in the method for automatic optimization of Maya-based files according to the above-described embodiments.
