[0050] Furthermore, the terms “first”, “second”, “third”, etc. are merely used for distinguishing descriptions and are not to be understood as indicating or implying relative importance.

[0052] refer to Figure 1 , is a schematic diagram of a method flow of a particle system storage method provided in an embodiment of the present application. The particle system storage method provided in an embodiment of the present application is as follows: Figure 1 As shown, the particle system storage method includes:

[0053] Step S101, obtaining a particle system set to be stored, wherein the particle system set to be stored includes a preset number of particle trees;

[0054] In a specific embodiment, a large number of particle systems are required to work together to achieve the rendering of an element effect, wherein the element effect includes flames, water flow, falling leaves, clouds, etc.

[0055] The particle system set to be stored includes all particle systems required to realize one or more element effects, specifically, Figure 2 As shown, the particle system includes a preset number of particle objects and a preset number of update strategy objects, and the particle objects and the update strategy objects form a tree structure.

[0056] In this embodiment, each particle system corresponds to a particle tree.

[0057] Step S102, obtaining a node array corresponding to each node in each particle tree in a preset order, wherein the node array includes a node type and a parent node index, and the node is a particle object or an update strategy object;

[0058] In a specific embodiment, after obtaining the particle system set to be stored, a traversal operation is performed for each particle system in the particle system set to determine the node type and parent node index of each node in the corresponding particle system. The node type and parent node index of the corresponding node are combined into a node array, and the node array is stored in the data content of the node. Among them, the field indicating the node type occupies 2 bytes, the field indicating the parent node index occupies 2 bytes, and a complete node array occupies 4 bytes.

[0059] Specifically, in the process of traversing each particle system, the number of nodes detected after traversing a complete particle system is recorded, and the number of nodes is stored in the data content of the corresponding node, wherein the field indicating the number of nodes occupies 4 bytes.

[0060] Each particle system set to be stored includes multiple particle systems, that is, multiple particle tree structures. When traversing each particle tree structure, the root node of each particle tree structure is marked to indicate the particle system composition of the particle system set to be stored. When reading the stored particle system set, the corresponding particle tree structure can be identified according to the pre-marked root node serial number and the number of nodes of the particle tree.

[0061] According to a specific implementation of the embodiment of the present application, the step of obtaining a node array corresponding to each node in each particle tree in a preset order includes:

[0062] Traversing the particle tree from the root node of the particle tree, and numbering each node in the particle tree according to a preset order, wherein the preset order is from the root node to the leaf node, and from the left leaf node to the right leaf node;

[0063] Get the node type and parent node index of each node to combine and generate the node array corresponding to each node.

[0064] In a specific embodiment, Figure 2 As shown, when traversing the particle tree, the traversal starts from the root node, and each traversed node is labeled, so as to obtain the labeling order of each particle tree node.

[0065] During the specific traversal process, the node type and parent node index of each node will be obtained. For example, when the storage device traverses to node 13, the node type of the 13th node will be obtained as particle 13, and the parent node index will be the 9th node; when traversing to node 14, the node type of the 14th node will be obtained as update strategy 14, and the parent node index will be the 9th node.

[0066] After obtaining the node type and parent node index of node 13, the node type and parent node index are combined to form a corresponding node array (particle 13, node 9). Specifically, the node type will be converted into a corresponding enumeration variable for storage during actual use.

[0067] Specifically, during the traversal process, the traversal is performed according to the extension direction of the leaf nodes of the particle tree structure, that is, the traversal is performed from the root node to the leaf node, and for the leaf nodes of the same layer, the traversal is performed from the left leaf node to the right leaf node.

[0068] According to a specific implementation of the embodiment of the present application, the update policy object includes a first update policy and a second update policy, wherein the first update policy is an update policy with a time series, and the second update policy is an update policy without a time series;

[0069] After the step of obtaining the node array corresponding to each node in each particle tree in a preset order, the method further includes:

[0070] The time series of all first update strategies of the particle system set to be stored are stored in a data pool, and the time series in the content data of each first update strategy is replaced by the corresponding time series index in the data pool;

[0071] The data pool is stored in a third file in binary form.

[0072] In a specific embodiment, the update strategy includes two types of data, namely a first update strategy with a time series and a second update strategy without a time series. The storage space range occupied by the second update strategy is fixed, and the storage space range occupied by the first update strategy changes according to the set time series.

[0073] The time series is set by corresponding technicians, has a large amount of repetitive time and occupies a large amount of space.

[0074] When storing the particle tree structure in the particle system set to be stored, the particle system storage device will store the time series of all first update strategies in a unified data pool during the process of traversing each particle tree structure, and store the time series index provided by the corresponding data pool in the content data of the original node.

[0075] By replacing the time series in each first update strategy with a time series index, the storage space occupied by the node content data corresponding to the first update strategy can be greatly reduced. For example, the storage space occupied by the time series is 64 bytes, and the storage space occupied by the time series index is 2 bytes.

[0076] In addition, according to a specific implementation of the embodiment of the present application, the data pool manages all first update strategies in the data pool based on a vector container.

[0077] In a specific embodiment, the vector container can store all time series in the particle system set to be stored, and can record multiple time nodes in the time series corresponding to each first update strategy. For the same parts between different time series, the vector can only store one same time file.

[0078] When calling the corresponding target time series from the vector container, the same time series part may be obtained first, and then the corresponding time nodes may be obtained to form a completed target time series.

[0079] After storing the time series of all first update strategies in the particle system set to be stored in the data pool, the data pool is written into a separate third file in binary form, thereby completing the space saving for the data content of each node and the space saving for the data pool.

[0080] Step S103, storing the number of nodes, content data of the nodes and the node array corresponding to each particle tree in a corresponding first file;

[0081] In a specific embodiment, the number of the first files may be one or more. The number of the first files is determined according to the number of particle trees in the particle system set to be stored, and each particle tree is stored in a corresponding first file.

[0082] After executing the traversal action for each particle tree in the above embodiment, the obtained number of nodes of the particle tree, the content data of the nodes and the node array of all nodes in the corresponding particle tree are stored in a first file.

[0083] Step S104, according to the relationship between the actual scopes of different attributes and the caches of different data types, the attributes of the nodes are sequentially written into the caches of different data types according to the order of the node array;

[0084] In a specific embodiment, arrays of different data types are set in advance as caches for storing node attributes, such as 11-bit Buffer, 4-bit Buffer, 8-bit Buffer, 16-bit Buffer, and 32-bit Buffer.

[0085] When storing the attributes of each node in the same particle tree, the attributes of the nodes are written into the corresponding cache according to the order of the node arrays according to the relationship between the actual scope and the caches of different data types.

[0086] Specifically, the program code for writing the attributes of the node into the corresponding cache according to the actual scope can be:

[0087]

[0088]

[0089]

[0090] It should be noted that the above codes are used to indicate that the attribute data corresponding to the node is written into different types of caches according to the actual scope of the attribute. Different codes may be used in actual operation, which is not limited here.

[0091] Step S105: Store the attributes of all nodes corresponding to a particle tree in each cache in a binary form in a corresponding second file.

[0092] In a specific embodiment, the number of the second files may be one or more. The number of the second files is determined according to the number of particle trees in the particle system set to be stored, and is not limited here.

[0093] All node attributes corresponding to each particle tree in the particle system data set to be stored are respectively stored in a separate second file.

[0094] The data space occupied by all node attributes of each cache and a particle tree in the cache is compactly stored in binary form, thereby preventing waste of data space.

[0095] Through the particle system storage method of this embodiment, the storage space occupied by the particle system can be reduced to the greatest extent, so that when using the particle system for rendering, as many particle systems as possible can be read to improve the rendering efficiency of the particle effect.

[0096] refer to Figure 3 , is a method flow diagram of a particle system reading method provided in an embodiment of the present application. The particle system reading method provided in an embodiment of the present application is as follows: Figure 3 As shown, the particle system reading includes:

[0097] Step S301, obtaining identification information of the particle tree to be read;

[0098] In a specific embodiment, when it is necessary to use the particle system data set stored in the above embodiment to perform particle effect rendering, the identification information of the particle tree to be read corresponding to the particle effect to be realized can be obtained from the particle effect to be realized.

[0099] Specifically, the identification information of the particle tree to be read includes the label sequence of the root nodes of the particle tree and the node quantity information of the corresponding particle tree. It should be noted that the setting of the identification information can also be adaptively set according to the existing particle system calling method, which will not be described in detail here.

[0100] Step S302, obtaining all nodes and all node arrays in order from a first file corresponding to the identification information of the particle tree to be read;

[0101] In a specific embodiment, when reading the corresponding particle tree, the corresponding first file is first searched according to the identification information, and all nodes and all node arrays with order are obtained from the first file. Among them, all nodes include content data of the nodes, and the content data includes a time series index.

[0102] According to the order of the node array, the particle system can be rearranged according to the tree structure of the particle tree, thereby restoring the stored particle tree structure.

[0103] Step S303, obtaining a preset number of caches from a second file of identification information corresponding to the particle tree to be read;

[0104] In a specific embodiment, after reading the tree structure of the particle tree, the corresponding second file is searched according to the identification information, and different types of cache are extracted from the second file.

[0105] Step S304, extracting the attributes corresponding to each node array from different types of caches according to the order of the node arrays, so as to form a target particle tree according to all the nodes, all the node arrays with order and the attributes corresponding to each node array.

[0106] In a specific embodiment, after extracting different types of cache from the second file, it is necessary to extract the attributes corresponding to each node from the different types of cache according to the order of the node array obtained in the above embodiment, and combine the node attributes with each node in the particle tree structure to obtain the particle tree stored in the first file and the second file.

[0107] According to a specific implementation of the embodiment of the present application, in the process of restoring the content data of each node in the particle tree, the corresponding time series can also be found from the third file in the above embodiment according to the time series index stored in each node in the particle tree, thereby restoring the content data of the particle tree with the update strategy of the time series.

[0108] According to a specific implementation of the embodiment of the present application, after extracting the attributes corresponding to each node array from different types of caches in the order of the node arrays, and forming a target particle tree according to all the nodes, all the node arrays in order, and the attributes corresponding to each node array, the method further includes:

[0109] Obtain a data pool storing time series from a third file;

[0110] The time series in the data pool is accessed according to the time series index in the node.

[0111] In a specific embodiment, according to the time series in the content data of each node of the particle tree, the corresponding data pool can be called from the third file in real time, and the pre-stored time series can be restored from the data pool.

[0112] Through the above-mentioned particle system reading method, it is possible to achieve the maximum saving of particle system storage space while ensuring the reversibility of the storage content, thereby ensuring the stability of particle effect rendering according to the particle system stored in the above-mentioned embodiment and improving the efficiency of particle system rendering.
