Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a mapping processing method according to an embodiment of the present invention, where the embodiment is applicable to a situation where an application software engine needs to obtain a mapping, and the method may be executed by a mapping processing apparatus, where the apparatus may be implemented in a software and/or hardware manner, and the apparatus may be configured in a computer device. As shown in fig. 1, the method may specifically include the following steps:
s110, obtaining a lossy compression map data packet, wherein the map data packet is generated by carrying out lossy compression on an original map by using a lossy compression method.
In this embodiment, lossy compression is different from lossless compression, which is based on the characteristic that human beings are not sensitive to some components in an image, and a certain image information is lost in the compression process to exchange for a larger image compression ratio. The original map may be a map applied to a three-dimensional scene, which may be, for example, a map of a character used in game play, or the like.
Preferably, the lossy compression map data packet may be obtained from a lossy compression map data packet obtained from an application software data packet, or may be obtained from a Web file server, or may be obtained from a terminal preset location. Before the lossy compression mapping data packet is obtained from the application software data packet, it is preferable that the original mapping data is lossy-compressed by using a lossy compression method, and then the lossy compression mapping data packet is attached to the application software data packet. Before the lossy compression map data packet is acquired from the Web file server, preferably, the original map data may be subjected to lossy compression by using a lossy compression method, and then the lossy compression map data packet is stored in the Web file server. Before the lossy compression map data packet is acquired from the preset terminal position, preferably, the lossy compression map data packet may also be acquired from a Web file server and downloaded to the preset terminal position.
Preferably, lossy compression is performed on the original map using a lossy compression method, which may include lossy compression on an invisible portion of the original map using a lossy compression encoder. Illustratively, lossy compression is applied to the invisible portion of the original map, and the resulting lossy compressed map may be 30% of the size of the original map. Wherein the invisible part may preferably be a part which is not sensitive to the human eye in the original map.
Preferably, the lossy compression encoder may include any one of a VP8 encoder, an HEVC encoder, a Guetzli encoder, a libjpeg encoder, an x264 encoder, and a dome encoder.
S120, converting the map data packet into a target map with a target format, wherein the target format is a format which can be recognized by an application software engine.
After the map data packet is obtained, the application software engine may not be able to directly identify the lossy compressed map data packet because the map data packet is in a lossy compressed format. Preferably, the format of the lossy compression map data packet can be converted into a format that can be recognized by the application software engine by using a corresponding format conversion algorithm. For example, converting the format of the lossy compressed map packet into the target map having the format recognizable by the application software engine may include decompressing the lossy compressed map packet, and converting the map format of the lossy original map obtained after decompression into the target map having the format recognizable by the application software engine. Illustratively, the application software engine may be a game engine, and accordingly, the object formats that the game engine can recognize may include any one of DDS, PVR, ASTC, and bytes.
It can be understood that, since the target map is obtained by using the map packet conversion format, the target map is the same as the original map, and may preferably be a map applied to a three-dimensional scene. Illustratively, it may be a character map used in the running of a game.
S130, storing the target map to a target position so that the application software engine can obtain the target map.
Preferably, the target map may be stored in a corresponding location in the application software, or the target map may be stored in a corresponding location in the terminal. For example, storing the target map to the target location may include storing the target map to a first target location in the terminal; or, the target map is stored to a second target location in the application software, so that the application software engine can read the corresponding target map at the first target location or the second target location.
Taking application software as game software, an application software engine as a game engine, a lossy compressed mapping data packet is stored in the game software data packet, the format of the lossy original mapping after decompression is jpg, and the target format is DDS as an example, the following steps are specifically described:
after the user opens the game software, the game software acquires the lossy compression mapping data packet from the game software data packet, and the game engine cannot identify the lossy compression mapping data packet. The game software utilizes a mapping format conversion algorithm of converting jpg into DDS, after a lossy compression mapping data packet is decompressed, the jpg mapping format of a lossy original mapping is converted into a target mapping with a DDS format which can be identified by a game engine, and after the target mapping is obtained, the target mapping is stored in a memory of the game software so that the game engine can read the target mapping.
In the map processing method provided by this embodiment, a lossy compressed map data packet is obtained, where the map data packet is a data packet generated by lossy compressing an original map by using a lossy compression method; converting the map data packet into a target map with a target format, wherein the target format is a format recognizable by an application software engine; and storing the target map to a target position so that the application software engine can acquire the target map, and the application software engine can simply and quickly acquire the map resource while reducing the size of the map resource.
Example two
Fig. 2 is a flowchart of a map processing method according to a second embodiment of the present invention. This embodiment may be combined with any optional solutions in one or more of the above embodiments, and in this embodiment, the converting the map data packet into a target map with a target format includes:
and calling a terminal processor to identify the map data packet by using a format conversion algorithm and convert the map data packet into a target map with a target format.
As shown in fig. 2, the method of this embodiment specifically includes:
s210, obtaining a lossy compression map data packet, wherein the map data packet is generated by performing lossy compression on an original map by using a lossy compression method.
S220, the calling terminal processor identifies the map data packet by using a format conversion algorithm and converts the map data packet into a target map with a target format, wherein the target format is a format which can be identified by an application software engine.
And S230, storing the target map to a target position so that the application software engine acquires the target map.
Illustratively, the terminal processor may be a CPU in the terminal. In the process of running the game, because the application software engine cannot identify the format of the original map, preferably, the terminal CPU can be called to decompress the map data packet, identify the decompressed lossy original map by using a corresponding format conversion algorithm, and convert the lossy original map into the target map. For example, if the format of the lossy original map is jpg and the format of the target map is DDS, the format conversion algorithm may be a format conversion algorithm for converting jpg into DDS. After decompressing the map data packet and obtaining the target map by using a format conversion algorithm, the terminal processor can store the target map in a memory of the application software so that an application software engine reads the target map; the target map may also be stored in a preset storage location of the terminal to have the application software engine read the target map.
Taking application software as game software, an application software engine as a game engine, a lossy compressed mapping data packet is stored in the game software data packet, the format of the lossy original mapping after decompression is jpg, and the target format is DDS as an example, the following steps are specifically described:
after the user opens the game software, the game software acquires the lossy compression mapping data packet from the game software data packet, and the game engine cannot identify the lossy compression mapping data packet. The game software calls a CPU in the terminal, decompresses a lossy compressed mapping data packet by using a mapping format conversion algorithm of converting jpg into DDS, converts the jpg mapping format of the lossy original mapping into a target mapping with a DDS format which can be identified by a game engine, and stores the target mapping in a memory of the game software after obtaining the target mapping so that the game engine can read the target mapping.
