Referring to fig. 1, fig. 1 is a schematic flow chart of a control method for modeling according to a first embodiment of the present application. In this embodiment, the execution subject of the control method for modeling is a device having control for modeling, and the control device for modeling may be a personal computer, a server, or the like, or may be a processor, a microprocessor, or the like. In the embodiment of the present application, a control apparatus for model creation (hereinafter referred to simply as an apparatus) is used as an execution subject of a control method for model creation, and the apparatus is not particularly limited. The control method of the modeling as shown in fig. 1 may include:

s101: and acquiring an initial model and initial directed distance field information corresponding to the initial model.

Before describing a control method for modeling in this embodiment, the related content of the directed distance field will be described for easy understanding.

Directed distance field (Signed Distance Field, SDF): refers to a sampling grid that determines whether a point is within an area, from a point in space to the nearest distance of the virtual model surface. Where Signed refers to the sign, distance refers to the Distance to the point, and Field refers to the area. I.e. the settlement results of the SDF characterize whether a point is inside or outside an area. As a rule, a negative value is used to represent the interior of an object and a positive value is used to represent the exterior of an object, where 0 is the surface.

As shown in fig. 2, fig. 2 is a visual information of a 2D directed distance field. The square in fig. 2 is a plurality of grids formed by discretizing a space, and the numbers in fig. 2 are elements in the directional distance field information, and each element is a floating point type data. The network structure formed by a plurality of grids is traversed through the whole space from any corner point to find the vertical line relative to the tangent line of the surface, at the moment, the numerical solution can be obtained by a point-to-plane distance formula, and if the vertical line is in the surface, the negative value distance is taken; if the vertical line is inside the surface, taking a positive distance; on the surface, 0 is taken.

A 3D directed distance field is a network of voxels, i.e. microcubes, that discretize a space.

The device acquires an initial model and initial directed distance field information corresponding to the initial model.

The initial model is a model which is initially created, generally refers to an electronic computer digital model, is created by a content creation tool, for example, max3D, maya, and is used by third party software, for example, a model file in suffix format such as · fbx · obj.

In this embodiment, only the appearance surface of the initial model is adjusted, and there is no limitation on the completion degree of the initial model, and there is no limitation on the modeling method of the initial model.

After the equipment acquires the initial model, initial directed distance field information corresponding to the initial model is generated according to the initial model. The initial directed distance field information corresponding to the initial model is essentially a three-dimensional array, and each element in the array is floating point type data.

S102: and when a model adjustment instruction is detected, acquiring incremental directional distance field information according to the model adjustment instruction.

The device monitors whether there is a model adjustment instruction. The model adjustment instruction may be triggered and generated by an adjustment operation of a user. Specifically, the model adjustment instructions include a model surface doming instruction and a model surface collapse instruction.

For example, as shown in fig. 3, fig. 3 is an interface schematic of the user for adjusting the initial model. In fig. 3 is a human virtual model. At the time of interaction, the user's adjustment operation is an operation for the pressing direction, for example, a left mouse button continuously clicks on the initial model surface. Generating a model adjustment instruction according to the operation of the user on the extrusion direction, wherein the model adjustment instruction comprises an adjustment direction and an extrusion adjustment value. In the interaction, the adjustment operation by the user is an operation for the arching direction, for example, a right click of the mouse continuously clicks the initial model surface. Generating a model adjustment instruction according to the operation of the user on the arching direction, wherein the model adjustment instruction comprises an adjustment direction and an arching adjustment value.

The model adjustment instruction comprises an adjustment direction and an adjustment value, and the device acquires incremental directional distance field information according to the model adjustment instruction. Wherein the incremental directional distance field information includes an adjustment direction, and an adjustment value.

In this embodiment, the incremental directional distance field information may be stored separately, which is convenient to call.

In an alternative embodiment, in order to achieve a better adjustment effect, an adjustment range corresponding to the initial model may be set to prevent excessive adjustment. Before S104, S105 to S106 may be included, referring to fig. 4, fig. 4 is a schematic flowchart of S105 to S106 in a control method for modeling according to the first embodiment of the present application, where S105 to S106 are specifically as follows:

s105: and acquiring an adjustment range corresponding to the initial model.

S106: and when the adjustment operation is detected, generating a model adjustment instruction according to the adjustment range and the adjustment operation.

The device obtains an adjustment range corresponding to the initial model. And the device stores an adjustment range corresponding to the initial model in advance. The adjustment range corresponding to the initial model is the range of the initial model allowing adjustment of the floating change. The adjustment range corresponding to the initial model is set according to the distance that the appearance of the initial model is allowed to collapse or arch when the model is manufactured.

When the device detects an adjustment operation, a model adjustment instruction is generated according to the adjustment range and the adjustment operation.

In an alternative embodiment, when the device detects an adjustment operation, the device obtains an adjustment direction and an initial adjustment value according to the adjustment operation, and when the initial adjustment value is within the adjustment range, the device generates the model adjustment instruction directly according to the initial adjustment value and the adjustment direction.

In an alternative embodiment, referring to fig. 5, fig. 5 is a schematic flowchart of S106 in a control method for modeling according to a first embodiment of the present application, and S106 includes:

s1061: generating an initial adjustment instruction according to the adjustment operation; the initial adjustment instruction comprises an initial adjustment value and an adjustment direction.

S1062: and when the initial adjustment value is not in the adjustment range, generating a model adjustment instruction according to the adjustment direction and the adjustment range.

The device may also generate an initial adjustment instruction according to the adjustment operation; the initial adjustment instruction comprises an initial adjustment value and an adjustment direction, and when the initial adjustment value is not in the adjustment range, the model adjustment instruction is generated according to the adjustment direction and the adjustment range.

For example, the adjustment range of the initial model is set to be [ -2.2,4.0], the initial adjustment value acquired by the device is 6, the adjustment direction is positive, and when the initial adjustment value is not within the adjustment range, a model adjustment instruction is generated according to the adjustment direction and the adjustment range. Then, the adjustment value in the model adjustment instruction finally generated by the device is 4, and the adjustment direction is positive.

In an alternative embodiment, to obtain the process of adjusting the initial model, we can obtain interpolation increment information, and adjust the initial model by overlapping the interpolation increment information multiple times. When the device detects the model adjustment instruction, interpolation increment information is obtained according to the model adjustment instruction, and increment directional distance field information is obtained according to the difference increment information.

The model adjustment instruction comprises an adjustment direction and an adjustment value, and the device calculates interpolation increment information according to the interpolation change amount and the adjustment data. Wherein the interpolation value used in each interpolation is increasing the interval time of each frame.

For example, the initial value of the first time T1 is a1, and the target value of the second time T4 is a 4. The difference between a4 and a1 is the adjustment value. The time of the intermediate interpolation is T2 and T3, and the interpolation increment information is a2 and a3 respectively, wherein a and T are in linear correlation.

S103: and obtaining target directional distance field information according to the incremental directional distance field information and the initial directional distance field information.

The device calculates target directional distance field information according to the incremental directional distance field information and the initial directional distance field information. That is, the device performs incremental computation on the initial directed-distance-field information according to the surface normal direction based on the incremental directed-distance-field information to obtain target directed-distance-field information.

The target directional distance field information is the directional distance field information adjusted in response to the adjustment instruction.

S104: controlling the initial model to be adjusted to a target model based on the target directional distance field information; the target model is a model corresponding to the target directional distance field information.

The device controls the initial model to be adjusted to a target model based on the target directional distance field information, wherein the target model is a model corresponding to the target directional distance field information.

When the device controls the initial model to adjust to the target model, the device actually completes the detection of the directional distance field information according to the surface normal direction, carries out offset and completes the adjustment.

In an alternative embodiment, when the device detects the model adjustment instruction, interpolation increment information is obtained according to the model adjustment instruction, and increment directed distance field information is obtained according to the difference increment information. After S104, S107 to S108 may be included, referring to fig. 6, fig. 6 is a schematic flowchart of S107 to S108 in a control method for modeling provided in the first embodiment of the present application, where S107 to S108 are specifically as follows:

s107: and acquiring an evolution adjustment model according to the initial directed distance field information and the interpolation increment information.

S108: and displaying the process of adjusting the initial model to the target model corresponding to the target directional distance field information based on the adjustment evolution model.

The device acquires an evolution adjustment model according to the initial directed distance field information and the interpolation increment information, wherein the evolution adjustment model is a model which evolves in the process of adjusting the initial model into the target model. The number of interpolation increment information can be one or a plurality of interpolation increment information, and each interpolation increment information corresponds to one adjustment evolution model.

For example, the initial value of the first time T1 is a1, and the target value of the second time T4 is a 4. The difference between a4 and a1 is the adjustment value. The time of the intermediate interpolation is T2 and T3, and the interpolation increment information is a2 and a3 respectively, wherein a and T are in linear correlation. a2 corresponds to a first tuned evolution model and a3 corresponds to a second tuned evolution model. And the process of adjusting the initial model to the target model corresponding to the target directional distance field information is from the initial model, the first adjustment evolution model, the second adjustment evolution model and the target model, and the equipment displays the change process. The evolution of the engraving animation of the virtual model is completed, and the effect of real-time engraving change of the virtual model can be seen.
