Moreover, the game is a hand game platform, and the performance of the game needs to be paid attention, so a technical scheme capable of generating the planet ground surface needs to be explored.

In the related art, a noise map is usually used for manufacturing a planet ground surface, but the obtained planet ground surface has poor effect due to the fact that the noise in the noise map is difficult to control, and the erosion effect on the planet surface is difficult to simulate due to the fact that the existing ground surface erosion process cannot be realized on a three-dimensional sphere corresponding to a planet.

Based on the above problems, embodiments of the present invention provide a model generation method, an apparatus, and an electronic device, and the technology may be applied in a model making scenario, especially a model making scenario.

In order to facilitate understanding of the embodiment of the present invention, a detailed description is first given of a model generation method disclosed in the embodiment of the present invention, and as shown in fig. 1, the method includes the following specific steps:

and S102, carrying out noise processing on a preset sphere model based on a preset noise parameter to obtain a first model.

The preset sphere model can be any sphere model input by a user, and the sphere model can be drawn by the user through drawing software or can be directly obtained from a preset file. The noise parameters may include parameters such as noise intensity, noise frequency, noise offset, and noise shape and size, and specific parameters included in the noise parameters may be set according to research and development requirements. During specific implementation, the noise of the preset sphere model can be adjusted and processed according to the noise parameters, then the preset sphere model is processed through the adjusted noise, and then the first model with the earth surface effect is obtained, namely the earth surface effect can be formed on the surface of the preset sphere model through the adjusted noise, and the earth surface effect is used for representing the blocks of the land and the sea on the surface of the planet.

Step S104, obtaining a spherical surface map of the first model, and carrying out erosion processing on the spherical surface map to obtain a second model with an erosion effect; wherein, the spherical map is used for indicating: height information of the first model surface.

In specific implementation, according to the height information of the first model surface, a spherical map of the first model surface can be obtained, the spherical map is a two-dimensional image, and the pixel value of each pixel point on the two-dimensional image corresponds to the height value of the corresponding position of the first model surface. The height information includes a height value of each point of the first model surface on a preset terrain.

After the spherical surface map of the first model is determined, the spherical surface map needs to be eroded, and a second model with an erosion effect is obtained. Specifically, the erosion processing may be performed by using an existing erosion flow, or by using an erosion effect to make software processing.

And step S106, setting a second model through the preset attribute control parameters to obtain a final model.

The attribute control parameters can comprise parameters such as the size of a planet, the number of the planet, the material of the surface of the planet and the like, and specific numerical values of the attribute control parameters can be controlled by a user, so that the form of the planet can be freely set according to the requirements of the user, a satisfactory model of the user can be obtained, and the efficiency and the experience of the user for making the model are improved.

According to the model generation method provided by the embodiment of the invention, firstly, a preset sphere model is subjected to noise processing based on a preset noise parameter to obtain a first model; further acquiring a spherical surface map of the first model, and carrying out erosion treatment on the spherical surface map to obtain a second model with an erosion effect; wherein, the spherical map is used for indicating: height information of the first model surface; and then setting a second model through preset attribute control parameters to obtain a final model. In the method, the earth surface effect can be obtained by presetting the sphere model through noise processing, and the earth surface erosion effect can be obtained by carrying out erosion processing on the spherical surface map of the earth surface effect, so that the method can automatically generate the model with the earth surface erosion effect; meanwhile, the mode can control the form of the generated model through the attribute parameters, so that models with different effects are obtained, and the freedom degree of model manufacturing is increased.

The embodiment of the present invention further provides another model generation method, which is implemented on the basis of the above-mentioned embodiment, and the method mainly describes a specific process (specifically, implemented by the following steps S202 to S204) of performing noise processing on a preset sphere model based on a preset noise parameter to obtain a first model, and a specific process (specifically, implemented by the following steps S206 to S208) of obtaining a sphere map of the first model, performing erosion processing on the sphere map to obtain a second model having an erosion effect; as shown in fig. 2, the method comprises the following specific steps:

step S202, input noise is adjusted based on the noise parameter, and final noise is obtained.

The noise parameters comprise one or more of noise intensity, noise frequency, noise offset and noise shape size. The noise may be random noise or noise modulated by a user. Specifically, in a general input noise processing sphere model, the obtained blocks of the earth surface of the model are relatively fine and are very different from natural land and ocean blocks, so that input noise needs to be adjusted through preset noise parameters, fine and broken noise is removed, or the fine and broken noise is normalized to obtain final noise. Fig. 3 shows an effect diagram obtained by directly processing a preset sphere model through input noise according to an embodiment of the present invention, where a circle with a white area and white spots on the top in fig. 3 is also a model obtained by directly processing the preset sphere model through input noise, and the model has more white spot areas, i.e., the blocks in the model are more broken, and have a larger difference from those of natural land and sea.

In a specific implementation, the noise parameters include noise intensity and noise shape size; thus, the input noise having a noise shape size larger than the preset size threshold may be determined as the final noise, that is, the final noise is the noise of the larger block. The preset size threshold may be set according to research and development requirements, for example, the preset size may be set to 2 square centimeters and the like. The following is the code that determines the final noise:

f in the above code represents input noise, start represents a preset size threshold of the shape and size of the noise, c can be understood as a parameter for smooth transition before and after processing, c =0 represents unsmooth, and c =1 represents completely smooth; the meaning of the softclip function body is that the input noise is adjusted according to a preset size threshold value to determine which of the input noise is small noise, and the small noise is removed.

And step S204, processing the preset sphere model through the final noise to obtain a first model.

The earth surface effect of the surface of the preset sphere model can be set through the final noise, and the first model is obtained, namely the first model is the preset sphere model with the earth surface effect. Fig. 4 is a schematic diagram of a first model according to an embodiment of the present invention.

And step S206, obtaining the spherical surface map of the first model based on the height information of the surface of the first model.

The height information comprises a height value of each point of the first model surface on a preset terrain, namely black, white and gray of final noise visualized on the model is height information. In a specific implementation, the step S206 can be implemented by the following steps 10-11:

and step 10, unfolding the surface of the first model into a two-dimensional grid according to a preset rule, and cutting the two-dimensional grid to obtain a square grid.

The preset rule may be set according to research and development requirements, and the preset rule may be a rule for processing texture coordinate information of the sphere model into a square shape. Specifically, the preset rule includes expanding the first model surface into an approximately square shape; further unfolding the first model surface into a two-dimensional grid; wherein the two-dimensional grid comprises square portions and sawtooth portions; and deleting the sawtooth part in the two-dimensional grid to obtain a square grid.

In a specific implementation, the texture coordinate information corresponding to the first model surface may be expanded into a two-dimensional grid including a square portion and a sawtooth portion, as shown in fig. 5, which is a schematic diagram of a two-dimensional grid provided by an embodiment of the present invention, and the sawtooth portion is represented by the upper and lower portions of the square portion in fig. 5. Fig. 6 is a schematic diagram of a square grid provided by an embodiment of the present invention, in which texture coordinates generally have two coordinate axes of U and V, and are therefore referred to as UV coordinates, U represents a distribution in a horizontal coordinate, and V represents a distribution in a vertical coordinate, and in some embodiments, the square grid may also be referred to as a UV grid.

And step 11, mapping the height information of the surface of the first model to a square grid to obtain a spherical mapping.

In a specific implementation, the vex code may be written by a preset cop (for a Composition operator) to map the height information of the first model surface onto the square grid to obtain the spherical map, as shown in fig. 7, which is a schematic diagram of the spherical map provided in the embodiment of the present invention. The cop module is generally used to process 2D (Two-Dimensional) information, and the embodiment may map the height information of the first model surface 3D (three-Dimensional) into 2D, that is, into a square grid in the cop module.

And S208, inputting the spherical map into preset terrain erosion software, and outputting a second model with an erosion effect.

During specific implementation, the spherical surface veneers are led into preset terrain erosion software, and the terrain erosion software can manufacture the terrain erosion effect to obtain a second model with the terrain erosion effect. Specifically, after the spherical surface map is obtained, the spherical surface map may be automatically imported into the terrain erosion software, or the spherical surface map may be manually imported into the terrain erosion model, and the specific importing manner is determined by the terrain erosion software used. In practical applications, the terrain erosion software may be existing software or self-developed software, for example, the terrain erosion software may be Gaea terrain software or WorldMachine software.

Specifically, the erosion effect of the second model earth surface can be modified by setting parameters related to the erosion effect in the terrain erosion software, and the user can manually modify the parameters related to the erosion effect, so that the personalized requirements of the user are improved.

And step S210, setting a second model through preset attribute control parameters to obtain a final model.

Firstly, adjusting input noise based on noise parameters to obtain final noise; processing the preset sphere model through final noise to obtain a first model; then, obtaining a spherical surface map of the first model based on the height information of the surface of the first model; and then inputting the spherical surface map into preset terrain erosion software, outputting a second model with an erosion effect, and setting the second model through preset attribute control parameters to obtain a final model. The method realizes the erosion of the spherical surface effect which cannot be realized by the prior art and a whole set of automatically generated frame, and different star shapes can be obtained by only modifying the attribute control parameters so as to obtain different effects; meanwhile, the method automatically realizes the effect of the earth surface of the planet, and greatly improves the model making efficiency compared with the manual iteration making method.

The embodiment of the present invention further provides another model generation method, which is implemented on the basis of the above embodiment, and the method mainly describes a specific process of setting a second model by using preset attribute control parameters to obtain a final model (specifically, implemented by the following steps S806 to S810); as shown in fig. 8, the method includes the following specific steps:

step S802, based on the preset noise parameters, noise processing is carried out on a preset sphere model to obtain a first model.

Step S804, obtaining the spherical surface map of the first model, and carrying out erosion processing on the spherical surface map to obtain a second model with erosion effect.

For a specific implementation manner of the steps S802 to S804, reference may be made to the above method embodiment, which is not described herein again.

Step 806, according to a preset rule, unfolding the surface of the first model into a two-dimensional grid, and cutting the two-dimensional grid to obtain a square grid.

The preset rule may be set according to research and development requirements, and the preset rule may be a rule for processing texture coordinate information of the sphere model into a square shape. Specifically, the preset rule includes expanding the first model surface into an approximately square shape; further unfolding the first model surface into a two-dimensional grid; wherein the two-dimensional grid comprises square portions and sawtooth portions; and deleting the sawtooth parts in the two-dimensional grid to obtain a square grid, wherein the square grid is shown in fig. 6, and only contains UV coordinate information and no height information.

And step S808, combining the square grids into a third model, and representing the third model by using point cloud to obtain a point cloud model.

Fig. 9 is a schematic diagram of a third model according to an embodiment of the present invention, where the third model is a sphere frame composed of square grids. Specifically, the spatial coordinates of each sampling point on the model surface can be obtained from the third model, and the set of the spatial coordinates of all the sampling points is called a point cloud.

And step S810, obtaining a final model based on the attribute control parameters, the point cloud model and the second model.

The attribute control parameters comprise one or more of the size of the planet, the material of the planet and the number of the planet; the size of the star can control the shape and size of the final model, the material of the star is used for controlling the surface material of the final model, and the number of the star is used for controlling the number of the finally generated models.

In a specific implementation, the step S810 can be implemented by the following steps 20 to 21:

and 20, adjusting the point cloud model through the attribute control parameters to obtain the adjusted point cloud model.

And step 21, setting the corrosion effect of the adjusted point cloud model based on the corrosion effect of the second model, and determining the point cloud model with the corrosion effect as a final model.

And transferring the erosion effect of the earth surface of the second model to the adjusted point cloud model to obtain the erosion effect of the point cloud model, and determining the point cloud model with the erosion effect as a final model.

In a specific implementation, the attribute control parameter is determined by: inputting necessary attribute information by compiling vex codes, wherein the attribute information comprises the size of a planet, a sphere model applied by the planet and the like; corresponding star materials can be compiled through data of the houdini engine automatically corresponding to the materials; the number of generated stars is determined by the wedge count.

In practical application, the invention realizes an automatic function in a PDG (programmable Dependency network) module, firstly, the wedge node sets the number of the planet, then, the mesh and texture automatic module is used for calling a functional node for obtaining a second model, and finally, a top node for scheduling and generating point cloud is used for adjusting the size of the planet, quoting examples, material parameters and other contents, and outputting a final model. The widget node is an iterator capable of transmitting parameters; a top node typically generates work items that will accomplish a particular task and store information in attributes.

In a concrete implementation, the generated final models all have high-mode eroded normal details, but each final model is a low-face number model that the hand game can bear. And then, only the first model is modified, so that various models, such as banana stars, duck stars and the like, can be obtained. The frame that whole automation model generated in this mode also can be expanded, and the planet quantity that generates can be thousands or even tens of thousands in addition, supplies fine arts producers to select to the efficiency of modeling has been promoted greatly.
