The embodiments described below with reference to the accompanying drawings are illustrative and intended to explain the present invention and should not be construed as limiting the present invention.
In the related art, in the process of rendering 3D characters according to user operation, the rendering efficiency is low due to large calculated data amount and complicated steps, and the 3D character editing process is easy to jam and affects user experience; according to the 3D character rendering method provided by the embodiment of the invention, firstly, an operation instruction input by a user is obtained, and the obtained operation instruction is analyzed to obtain a 3D character rendering parameter corresponding to the operation instruction; then, whether a rendering image corresponding to the 3D character rendering parameter exists in the cache data or not is judged, if yes, the rendering image is called to directly display the rendering image to a user, so that a repeated calculation process is not needed according to the operation instruction, and the performance pressure brought by 3D character rendering is reduced; then, if the rendering image corresponding to the 3D character rendering parameter does not exist in the cache data, whether staged cache data corresponding to the 3D character rendering parameter exists in the cache data is judged, the staged cache data is called when the staged cache data corresponding to the 3D character rendering parameter exists in the cache data, and 3D character rendering is carried out according to the staged cache data and the 3D character rendering parameter, so that the rendering efficiency of the 3D character is effectively improved, the phenomenon of pause in the process of editing the 3D character by a user is prevented, and the user experience is improved.
In order to better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
In order to better understand the technical scheme, the technical scheme is described in detail in the following with reference to the attached drawings of the specification and specific embodiments.
Fig. 1 is a schematic flow diagram of a 3D text rendering method according to an embodiment of the present invention, and as shown in fig. 1, the 3D text rendering method includes the following steps:
s101, an operation instruction input by a user is obtained, so that a corresponding 3D character rendering parameter is obtained according to the operation instruction.
That is to say, in the process of editing the 3D text by the user, an operation instruction of the user is obtained (for example, adding 3D text content, deleting 3D text partial content, changing 3D text color, changing 3D text font size, and the like), and after the operation instruction of the user is obtained, a 3D text rendering parameter corresponding to the operation instruction is obtained according to the operation instruction, so that the 3D text is rendered according to the 3D text rendering parameter subsequently.
It should be noted that the data content included in the 3D rendering parameter may be various, for example, 3D text color, text font, text content, text font size, mapping information, illumination parameter, and the like; the specific data content included in the 3D rendering parameters is not limited herein.
S102, judging whether a rendering image corresponding to the 3D character rendering parameter exists in the cache data, if so, executing a step S103, and if not, executing a step S104.
And S103, calling the rendering image.
That is to say, if the cache data is queried according to the 3D text rendering parameters and then the rendering image corresponding to the 3D text rendering parameters is determined to exist in the cache data, the rendering image is called to directly display the rendering image to the user, so that repeated 3D text rendering according to the operation instruction is not required, a large amount of computing resources can be saved, and the performance pressure caused by 3D text rendering is reduced.
And S104, judging whether staged cache data corresponding to the 3D character rendering parameters exist in the cache data, calling the staged cache data when the staged cache data corresponding to the 3D character rendering parameters exist in the cache data, and rendering the 3D characters according to the staged cache data and the 3D character rendering parameters.
That is, if the cache data does not have the rendering image corresponding to the 3D text rendering parameter, further determining whether staged cache data corresponding to the 3D text rendering parameter exists in the cache data, it can be understood that during the rendering process of the 3D text, many staged data may occur, for example, text font data of the 3D text, text vertex data of the 3D text, map data of the 3D text, and illumination data of the 3D text; therefore, when the cache data is inquired according to the 3D character rendering parameters, if the staged cache data corresponding to the 3D character rendering parameters exists in the cache data, the staged cache data is called, and the 3D characters are rendered according to the staged cache data and the 3D character rendering parameters, so that the calculation amount required in the 3D rendering process can be reduced to a great extent; the 3D character rendering efficiency is improved, and the phenomenon that a user is blocked when editing the 3D characters is prevented.
It can be understood that, in the process of editing 3D text by a user, rendering parameters of the 3D text are frequently changed according to an instant visual effect in the process of editing the 3D text, and therefore, in the process of continuous operation, the computational pressure caused by 3D rendering is huge; therefore, according to the 3D text rendering method provided by the embodiment of the present invention, in the editing process, first, when a 3D text rendering parameter provided by a user is obtained for the first time, rendering of a 3D text is performed according to the 3D text rendering parameter, in the rendering process, staged data corresponding to the 3D text rendering parameter is cached to generate staged cache data, a rendering image is obtained after the rendering process is continued, and the rendering image and the 3D text rendering parameter corresponding to the rendering image are cached; then, in the process that the user continuously edits the 3D characters, if the current 3D character rendering parameters input by the user are obtained, the cache data is inquired according to the current 3D character rendering parameters to judge whether the corresponding rendering images are cached in the current 3D character rendering parameters or not, and if the corresponding rendering images are cached in the current 3D character rendering parameters, the rendering images are called; if not, whether the 3D character rendering parameter is cached with corresponding staged cache data is further judged, if yes, the staged cache data is called, and further 3D character rendering is carried out according to the staged cache data and the 3D character rendering parameter, so that the calculation resources required by a user in the process of continuously editing the 3D characters can be greatly saved, especially when the user frequently changes the 3D character rendering parameter, performance pressure is more easily caused, and the editing process is blocked.
In addition, it should be noted that, in the process of editing the 3D text through the WEB browser, due to the limitation of the performance of the WEB browser, more performance bottlenecks exist in the rendering and updating of the 3D text, so that when a user uses the WEB browser to edit the 3D text online, the stuck phenomenon caused by the calculated amount is more obvious.
In an embodiment of the present invention, as shown in fig. 2, the 3D text rendering method includes the following steps:
s201, acquiring an operation instruction input by a user so as to acquire a corresponding 3D character rendering parameter according to the operation instruction.
S202, judging whether a rendering image corresponding to the 3D character rendering parameter exists in the cache data, if so, executing the step S203, and if not, executing the step S204.
And S203, calling the rendered image.
The steps S201 to S203 are the same as the steps S101 to S103, and are not described herein again.
S204, judging whether character font and character vertex data corresponding to the character content exist in the cache data, if so, executing the step S205, and if not, executing the step S206.
S205, calling character vertex data, and executing step S210.
That is to say, if the 3D text rendering parameter does not have a corresponding rendering image, the cache data is queried according to the text font and the text content, and it is determined whether text vertex data corresponding to the text font and the text content exists in the cache data, and if so, the text vertex data is called, so as to perform 3D text rendering according to the text vertex data and the 3D text rendering parameter in the subsequent process, thereby, the calculation of the text vertex corresponding to the 3D text does not need to be repeated in the 3D text rendering process, and the calculation resources in the 3D text rendering process are saved.
S206, judging whether character font data corresponding to the character font exists in the cache data, if so, executing the step S207, and if not, executing the step S208.
S207, the character font data is called, and step S09 is executed.
S208, obtaining a font file corresponding to the character font, and analyzing the font file to obtain character font data corresponding to the character font.
S209, generating corresponding character vertex data according to the character font data.
And S210, rendering the 3D characters according to the character vertex data and the 3D character rendering parameters.
That is, if the cache data does not have the character font and the character vertex data corresponding to the character content, the cache data is inquired according to the character font to judge whether the cache data has the character font data corresponding to the character font, if so, the character font data is called to generate the corresponding character vertex data according to the character font data, and the 3D character rendering is carried out according to the character vertex data and the 3D character rendering parameter; therefore, when the character font data exist in the cache data, the database does not need to be repeatedly inquired according to the character font to obtain the character font file, the obtained character font file does not need to be analyzed, and the calculation resources required in the 3D character rendering process can be greatly saved.
In summary, according to the 3D text rendering method in the embodiment of the present invention, first, an operation instruction input by a user is obtained, and the obtained operation instruction is analyzed to obtain a 3D text rendering parameter corresponding to the operation instruction; then, judging whether a rendering image corresponding to the 3D character rendering parameter exists in the cache data, if so, calling the rendering image to directly display the rendering image to a user, so that a repeated calculation process is not required according to the operation instruction, and the performance pressure brought by 3D character rendering is reduced; then, if the rendering image corresponding to the 3D character rendering parameter does not exist in the cache data, whether staged cache data corresponding to the 3D character rendering parameter exists in the cache data is judged, the staged cache data is called when the staged cache data corresponding to the 3D character rendering parameter exists in the cache data, and 3D character rendering is carried out according to the staged cache data and the 3D character rendering parameter, so that the rendering efficiency of the 3D character is effectively improved, the phenomenon of pause in the process of editing the 3D character by a user is prevented, and the user experience is improved.
