Detailed Description

In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The model processing method provided by the invention can be executed by a terminal, and the terminal includes but is not limited to various computers, mobile phones, tablet computers, wearable devices and the like.

Example one

As shown in fig. 1, in one embodiment of the model processing method, the method includes the steps of:

and S100, obtaining a model to be processed.

The model to be processed may be drawn by three-dimensional modeling software, and specifically, in this embodiment, drawing the model to be processed by a blender, that is, obtaining the model to be processed includes:

and receiving a modeling operation instruction through the blender application software to draw the model to be processed.

Specifically, a user can click a menu option of application software through a mouse or use a shortcut key of the application software through a keyboard to input an operation instruction, when the model to be processed is generated, the user inputs a modeling operation instruction, and the terminal draws the model to be processed according to the modeling operation instruction after receiving the modeling operation instruction.

S200, receiving a first operation instruction through the blender application software, modifying the shader attribute of the model to be processed into a background according to the first operation instruction, and generating a target model.

And after the model to be processed is obtained, processing the model to be processed in a blender application software, wherein the blender is an open-source cross-platform all-around three-dimensional animation software, has the capability of directly exporting a gltf format model with high compatibility at a web end, and provides good stable material output. When the model to be processed is drawn through the blender, the model to be processed can be directly opened in the blender, and when the model to be processed is not drawn through the blender, the model to be processed can be opened through the blender after format conversion processing.

The blend provides a node function for setting the model material and texture, if the complex material and texture are to be realized, the node function is needed, as shown in fig. 2, the left side of each node is used as input, the right side is used as output, the nodes are influenced with each other progressively, the latter is influenced, finally the desired effect is obtained, and the complex material effect can be realized by the nodes. In this embodiment, the setting of the light-free material is realized through a "background" node, and specifically, as shown in fig. 3 and 4, a user may open a shader option in a blender and select the "background" node to issue the first operation instruction, so as to modify the shader attribute of the to-be-processed model into a background. The "background" node is only used for the output of the world surface, that is, the node is used for rendering the background material except the objects in the scene, but when the background shader is used for the ordinary objects, the background shader has the effect of being free from light, so that the background is not affected by any other light and is always kept at a constant infection value. Changing the shader node of the model to be processed into a background node can make the target model be made of a light-free material, so that the effect of light-free is achieved after the target model is led into a business scene.

Although the background node does not support diffuse reflection or color rendering of a metal surface, but supports change of transparency, in a possible implementation manner, in order to adjust a display effect of the model to be processed, before generating the target model, the model processing method provided by this embodiment further includes the steps of:

As shown in fig. 5 and 6, if the transparency of the model to be processed is to be adjusted, the blending mode in the material setting may be changed to Alpha blending, specifically, after the blending mode in the material setting is modified to "Alpha" blending in the blender, the transparency of the model to be processed may be changed by adjusting the value of a in the rgba parameter in the color. It should be noted that, at present, modifying the transparency of the to-be-processed model according to the second operation instruction is only used in the blend 2.82 and the blend 2.83, and other versions are not applicable, so that if the non-light-receiving effect of the translucent model needs to be achieved, one of the two versions, i.e., the blend 2.82 and the blend 2.83, needs to be used.

In another possible implementation manner, in addition to setting a shader as a background node, as shown in fig. 7, a texture of a picture may be added, so that the set texture of the picture also becomes light-insensitive, that is, before the target model is generated, the method further includes the steps of:

And after the model to be processed is subjected to the processing by the blender, generating a target model, namely, the target model is the model to be processed with the changed attribute parameters. Referring to fig. 1 again, the model processing method provided in this embodiment further includes the steps of:

s300, importing the target model into a service scene.

Specifically, the importing the target model into the service scenario includes:

s310, exporting the target model from the Blender application software in a gltf format;

s320, loading the target model into a service scene of the webgis system through a gltf loader.

The compatibility of the gltf format at the web end is very high, the model to be processed is processed by the blender to obtain the target model, and then the target model is derived from the blender in the gltf format, as shown in fig. 8.

After the target model in the gltf format is obtained, a file in the gltf format needs to be loaded through a gltflader (gltf loader) in the tree, and in order to load the target model into a service scene of the webgis system, the gltflader needs to be embedded into a model loader file of the gis system, so that the target model in the gltf format is loaded into the gis system. Specifically, before the target model is loaded into the service scene of the webgis system by the gltf loader, the model processing method provided in this embodiment further includes the steps of:

preparing a gltf loader file;

the gltf loader file is introduced into the model loader file of the webgis system.

The gltf loader file can be downloaded in the tree official website, specifically, the tree official website provides the gltf loader file, and the tree gltfloader () is introduced into the model loader file of gis system by combining the case code in the file of the official website download document, so that the target model in the gltf format can be loaded through the model loader of gis system.

Specifically, the loading the target model into a business scenario of the webgis system through a gltf loader includes:

and after the loading parameters of the target model are set in the model loader file, loading the target model into the service scene through the model loader file.

After the gltf loader file is introduced into the model loader file of the webgis system, before the target model is loaded, relevant loading parameters such as model position, size, height and the like need to be introduced, so that the target model can be successfully imported into a scene.

As shown in fig. 9, the target model (the right model in fig. 9) with modified shader attributes as the background and the model (the left model in fig. 9) which is not processed by the light effect implementation method provided by the present invention are imported into the scene, when there is no white scene light, the left side has diffuse reflection effect, and after adding the white scene light, as shown in fig. 10, the left model becomes all white after receiving illumination of a white scene, etc., while the right model remains unchanged and is not affected by illumination.

In summary, the embodiment provides a model processing method, where a shader attribute of a model is modified into a background by a blender and then is imported into a service scene, and a background node in the blender is specifically used for rendering a background material except for an object in a manufacturer, and when a background shader is used for a common object, the background material is not affected by other light and is maintained at a constant rendering value, so that a light-free effect of the model in the scene is achieved.
