Referring to fig. 1, a three-dimensional model format conversion method provided in an embodiment of the present application is applied to a data processing server of a local area network, where the local area network includes a plurality of clients communicatively connected to the data processing server, and the data processing server is installed with a plurality of three-dimensional modeling software; the method comprises the following steps:
A1. acquiring a three-dimensional model diagram to be converted and target format information from a user side;
A2. acquiring current format information of a three-dimensional model diagram to be converted;
A3. selecting target three-dimensional modeling software according to the current format information and the target format information;
A4. operating the target three-dimensional modeling software to convert the format of the three-dimensional model diagram to be converted into a target format to obtain a converted three-dimensional model diagram;
A5. and sending the converted three-dimensional model diagram back to the user side.
In practical applications, the data processing server may be a data processing server in the three-dimensional model format conversion system shown in fig. 4 or fig. 5, the user side is correspondingly a user side in the three-dimensional model format conversion system, and the three-dimensional model format conversion system is a local area network system; the user terminal may be, but is not limited to, a PC, a tablet, a mobile phone, and the like. The three-dimensional modeling software installed on the data processing server includes a plurality of three-dimensional modeling software in the prior art (such as, but not limited to, 3d max, blend, Maya, UG, solidworks, CATIA, pro, etc.).
By adopting the three-dimensional model format conversion method, only a plurality of three-dimensional modeling software are needed to be installed in the data processing server in the local area network, other user sides in the local area network can realize automatic conversion among different three-dimensional model formats through the data processing server, the user does not need to operate the corresponding three-dimensional modeling software in the user side for format conversion, and the format conversion operation of the three-dimensional model is convenient; in addition, because a plurality of three-dimensional modeling software do not need to be installed in each user side, the cost for purchasing the three-dimensional modeling software can be reduced on one hand, and the performance requirements of each user side can be reduced on the other hand, so that the purchase cost of the user side is reduced, and the operation cost of an enterprise is reduced.
In some embodiments, the current format information of the three-dimensional model map to be converted is directly sent by the user terminal, and thus, step a2 includes: and acquiring the current format information sent by the user side.
In other embodiments, the current format information of the three-dimensional model diagram to be converted is automatically extracted from the file name of the three-dimensional model diagram to be converted by the data processing server, so that the user does not need to perform the operation of selecting or filling the current format, and the convenience of the operation is improved. At this time, step a2 includes:
extracting a file name of a three-dimensional model diagram to be converted;
and extracting the suffix name of the file name to obtain the current format information of the three-dimensional model graph to be converted.
In practical applications, there may be more than one three-dimensional modeling software in the data processing server capable of converting the current format into the target format, and therefore, one of the three-dimensional modeling software needs to be selected to perform the format conversion operation, so that step a3 includes:
A301. inquiring in a preset conversion function query table according to the current format information and the target format information to obtain a type list of three-dimensional modeling software capable of converting the current format into the target format;
A302. and selecting one three-dimensional modeling software from the category list as target three-dimensional modeling software.
Wherein, a conversion function lookup table is established in advance according to the import format and the export format supported by each three-dimensional modeling software. In some embodiments, the conversion function lookup table creates a header of a plurality of category lists in an "x-y" format, where x is a current format name, y is a target format name, and the category lists record category information of all three-dimensional modeling software capable of realizing x → y format conversion. For example, when the header of the category list converted from the obj format to the gltf format is obj-gltf, and query is performed, a character string of "x-y" is generated according to the current format name and the target format name, and then the character string is matched with each header, and finally the corresponding category list is determined.
In step a302, a three-dimensional modeling software may be randomly selected from the category list as a target three-dimensional modeling software.
In some preferred embodiments, the category list is sorted in descending order according to the conversion speeds of the various three-dimensional modeling software (i.e., the higher the conversion speed, the higher the sorting), so that in step a302, the first three-dimensional modeling software in the category list is selected as the target three-dimensional modeling software; thereby improving format conversion efficiency. Further, step a4 includes: acquiring time-use data for converting the format of the three-dimensional model diagram to be converted into a target format, acquiring file size data of the three-dimensional model diagram to be converted, dividing the file size data by the time-use data to obtain the conversion speed of the target three-dimensional modeling software, and updating the sequence of various three-dimensional modeling software in a corresponding category list according to the conversion speed. Therefore, the accuracy of sequencing is improved, and high format conversion efficiency is ensured.
In practical application, different three-dimensional modeling software has different specific operation steps during format conversion, different format conversion operations can be performed by manually operating various three-dimensional modeling software in advance, specific steps (including any operation steps executed by a mouse and a keyboard) of each format conversion operation are recorded, a corresponding script file is generated, and the corresponding script file is called to perform format conversion operation during actual format conversion processing, so that automation of a conversion process is realized. At this time, step a4 includes:
calling a corresponding script file according to the current format information, the target format information and the target three-dimensional modeling software; the script file records corresponding conversion operation steps;
and running the target three-dimensional modeling software according to the script file, and executing format conversion operation of the three-dimensional model diagram to be converted.
The file names of all script files can be established by using the naming rule of 'x-y', wherein x is the current format name, and y is the target format name, so that when the script files are called, an 'x-y' character string is generated according to the current format name and the target format name, then the character string is matched with the file names of the script files, and finally the corresponding script files are determined.
In some embodiments, the three-dimensional model graph to be converted in step a1 is uploaded by a user through a user terminal, when the user wants to perform format conversion of the three-dimensional model graph, an upload file button is generally clicked in a corresponding application interface in the user terminal, so as to form a format conversion trigger instruction and send the format conversion trigger instruction to the data processing server, after the user clicks the upload file button, the application interface pops up a dialog box, which includes a file storage path setting field to be converted, a target format setting field, and a converted file storage path setting field, the user needs to input or select a storage path of the three-dimensional model graph to be converted in the file storage path setting field to be converted, input or select a target format in the target format setting field, input or select a converted three-dimensional model storage path in the converted file storage path setting field, after a user sets a storage path and a target format of a file to be converted and a storage path of the converted file and clicks a determination button, the user side sends storage path information of a three-dimensional model graph to be converted, target format information and the converted three-dimensional model graph to a data processing server; and when the user side receives the converted three-dimensional model graph sent back by the data processing server, the file storage is carried out according to the storage path information of the converted three-dimensional model graph.
Preferably, in order to improve convenience when the user sets the storage path of the file to be converted, step a1 includes:
after receiving a format conversion triggering instruction of the user side, sending a corresponding first common path option list to the user side; the first common path option list comprises at least one piece of storage path information of the file to be converted commonly used by the user side; the first common path option list is used for a user to select a storage path of the three-dimensional model graph to be converted;
and acquiring the corresponding three-dimensional model graph to be converted according to the storage path of the three-dimensional model graph to be converted finally determined by the user side, and updating the first common path option list.
The data processing server sends back a corresponding first common path option list after receiving a format conversion triggering instruction of a user side, the user side displays the first common path option list on an application interface, a user selects a correct path in the first common path option list (selects by clicking), selected path information is filled in a storage path setting column of a file to be converted, the user can fill in a file name of a three-dimensional model graph to be converted after the path information to determine the file to be uploaded, or the user can click a browsing button of the storage path setting column of the file to be converted to directly open a folder to which the selected path information points, and then the file to be uploaded is clicked. If the first common path option list does not contain the required path information, the user can directly fill the required path information and the file name of the three-dimensional model diagram to be converted in the file storage path setting column to be converted, or directly click a browsing button to perform selection operation to determine the file to be uploaded.
The first common path option list generally includes only the most frequently used N storage path information of the files to be converted, where N is a preset positive integer value, and may be set according to actual needs, for example, N is 1-3, that is, the frequently used storage path information of the files to be converted refers to the N storage path information of the files to be converted.
When the first common path option list is updated, sorting in a descending order (that is, the sorting is earlier when the used times are more) according to the used times (which may be all times since the user accesses the local area network or the total times in the latest preset time period, which may be set according to actual needs, for example, 3 days, but not limited thereto) of the storage path information of each file to be converted that is used once, and then replacing the original storage path information of the N files to be converted with the storage path information of the N files to be converted that is sorted before. Therefore, the probability that the first common path option list contains the storage path information of the file to be converted, which is required by the user, is improved, and the operation convenience is further improved. When the file storage path information to be converted is sorted, if the used times of the plurality of file storage path information to be converted are the same, the file storage path information to be converted is sorted in a descending order according to the used times of the previous-level path information of the file storage path information to be converted (for example, if the file storage path information to be converted is 'E: \ AA \ BB', the previous-level path information is 'E: \ AA \'), and if the used times of the plurality of previous-level path information are the same, the file storage path information to be converted is sorted in a descending order according to the used times of the next previous-level path information until the sorting is completed.
Preferably, in order to improve convenience when the user performs the target format setting, step a1 includes:
after receiving a format conversion triggering instruction of the user side, sending a corresponding common target format option list to the user side; the common target format option list comprises at least one piece of target format information commonly used by the user side; the common target format option list is used for a user to select a target format;
and acquiring the target format information finally determined by the user side, and updating the common target format option list according to the target format information.
After receiving a format conversion triggering instruction of the user side, the data processing server sends back a corresponding common target format option list, the user side displays the common target format option list on an application interface, and the user selects a correct target format in the common target format option list (selects by clicking). If the common target format option list does not contain the correct target format, the user can directly fill the final target format in the target format setting column or directly click a pull-down button to select the final target format in the pull-down menu.
The common target format option list generally includes only M pieces of most common target format information, where M is a preset positive integer value and may be set according to actual needs, for example, M is 1 to 3, that is, the common target format information refers to the M pieces of target format information.
When the common target format option list is updated, sorting in a descending order (that is, the sorting is closer to the front when the used times are more) according to the used times of each piece of target format information used once (which may be all times since the user side accesses the local area network or the total times in a latest preset time period, which may be set according to actual needs, for example, 3 days, but not limited thereto), and then replacing the original M pieces of target format information with the M pieces of target format information sorted before. Therefore, the probability that the common target format option list contains the target format information required by the user is improved, and the operation convenience is further improved. When the target format information is sorted, if the used times of a plurality of target format information are the same, the target format information is sorted according to the initial sorting order of the format names (suffix names) of the target format information.
Preferably, in order to improve convenience when the user performs the switching of the file storage path setting, step a1 includes:
after receiving a format conversion triggering instruction of the user side, sending a corresponding second common path option list to the user side; the second common path option list comprises at least one converted file storage path information commonly used by the user side; the second common path option list is used for a user to select a storage path of the converted three-dimensional model graph;
and updating the second common path option list according to the storage path of the converted three-dimensional model graph finally determined by the user side.
The data processing server sends back a corresponding second common path option list after receiving a format conversion triggering instruction of the user side, the user side displays the second common path option list on an application interface, the user selects a correct path in the second common path option list (selects by clicking), and the selected path information is filled in a file storage path column after the conversion is selected. If the second common path option list does not contain the required path information, the user can also directly fill the required path information in the post-conversion file storage path column, or directly click a browsing button to perform selection operation to determine the required path information.
The second common path option list generally includes only the most frequently used storage path information of the O converted files, where O is a preset positive integer value, and may be set according to actual needs, for example, O is 1 to 3, that is, the frequently used storage path information of the converted files refers to the storage path information of the O converted files.
When the second common path option list is updated, sorting in a descending order (i.e., sorting is more advanced as the used times are more) according to the used times (which may be all times since the user accesses the local area network or the total times in a recent preset time period, which may be set according to actual needs, for example, 3 days, but is not limited thereto) of the converted file storage path information used once (i.e., sorting is more advanced as the used times are more), and then replacing the original O converted file storage path information with the O converted file storage path information sorted before sorting. Therefore, the probability that the second common path option list contains the converted file storage path information required by the user is improved, and the operation convenience is further improved. When the converted file storage path information is sorted, if the used times of a plurality of converted file storage path information are the same, the converted file storage path information is sorted in a descending order according to the used times of the last-level path information of the converted file storage path information (for example, if the converted file storage path information is ' F: \ CC \ DD ', the last-level path information is ' F: \ CC \ "), and if the used times of a plurality of last-level path information are the same, the converted file storage path information is sorted in a descending order according to the used times of the next-level path information until the sorting is completed.
