Technical Field

Background

Traditionally, in the process of character animation in which a three-dimensional body model and a garment model are independent, the body model and the garment model are usually modeled separately to improve reusability of the garment. The realization method is that when the designer makes the clothing model, the designer designs a plurality of mixed shape parameters. For example, different parameters are designed to control the chest circumference, waist circumference, sleeve length, trouser length, etc. of the garment. When the same garment is fitted to different mannequins, the values of a plurality of shape parameters need to be manually adjusted to enable the garment to be correctly fitted with the current mannequin. However, in the actual fitting process, a rich garment model and a three-dimensional human body model may be formed, and as shown in fig. 1, the three-dimensional human body model and the garment model are schematically illustrated in the mold-through phenomenon.

In the prior art, in order to solve the mold penetration phenomenon of the three-dimensional human body model and the garment model, manual adjustment is performed, for example, more shape parameters are added, the definition of the shape parameters is adjusted, or manual repair is performed locally for each three-dimensional human body model. However, these methods are time consuming and result in inefficient die-threading of three-dimensional body models and garment models.

As shown in fig. 5, a schematic flow chart of a method for solving the problem of threading the three-dimensional human body model and the garment model includes the following steps:

step 501: detecting each human body patch intersected with a clothing patch of a target object in a three-dimensional human body model of the target object to obtain an intersected pair set, wherein any intersected pair in the intersected pair set comprises a pair of human body patches and clothing patches which are intersected;

the method for detecting each human body panel intersecting with a garment panel of the target object in the three-dimensional human body model of the target object may be a bounding box detection algorithm, an octree, a kd-tree (k-dimensional-tree), and other algorithms, and the specific detection method may be set according to the actual situation, and the specific detection algorithm is not limited in this embodiment.

And, each intersecting pair in the intersecting pair set in the present embodiment is in the form of { tooth } _i ，body _i Wherein, the booth _i For indexing pieces of clothing in a clothing model, body _i Is an index of the human body patch in the three-dimensional human body model. The form of the intersecting pair in this embodiment is merely for illustration, and the specific form may be set according to the actual situation, and this embodiment is not limited herein.

Step 502: fusing each adjacent garment patch in the intersecting pair set to obtain at least one intersecting region;

in one embodiment, step 502 may be implemented as: for any one garment panel in the intersecting pair set, if the garment panel has the same edge as any other garment panel in the intersecting pair set, determining that the other garment panels are garment panels adjacent to the garment panel; and fusing the clothing surface patch with the other clothing surface patches based on the same edge to obtain the intersection area.

For example, as shown in fig. 6, garment panel 1 includes edge AB, edge AC, and edge BC. Garment panel 2 includes edge AB, edge AD, and edge BD. It is determined that the same edge AB exists for garment panel 1 and garment panel 2. Then garment panel 1 and garment panel 2 may be fused based on edge AB. The intersection region shown in fig. 6 is obtained.

Step 503: aiming at any clothing vertex in any intersection area, obtaining each edge connected with the clothing vertex in the clothing model, and determining whether the clothing vertex is subjected to die punching with the three-dimensional human body model and the die punching type or not based on the position of each edge and the position of each human body surface piece intersected with a target clothing surface piece, wherein the target clothing surface piece is each clothing surface piece forming the intersection area;

in the following, a detailed description is given of a manner of determining whether a clothing vertex is in a form penetrating with a three-dimensional human body model and a manner of determining a form penetrating type, as shown in fig. 7, which is a specific flowchart and includes the following steps:

step 701: traversing each edge, and aiming at any traversed edge, obtaining a direction vector of the edge according to the position of each vertex in the edge;

for example, the position coordinates of each vertex of the side AB are A (x) ₁ ，y ₁ )，B(x ₂ ，y ₂ ) The direction vector of the straight line on which the side AB is located is (x) ₂ -x ₁ ，y ₂ -y ₁ )。

Step 702: traversing each human body patch intersected with a target clothing patch, and determining a normal vector of the human body patch based on the position of each vertex in the human body patch aiming at any traversed human body patch;

the method for determining the plane normal vector is a method in the prior art, and this embodiment is not described herein again.

Step 703: determining whether the human body patch and the edge are intersected or not according to the normal vector and the direction vector of the human body patch, if so, executing a step 704, and if not, executing a step 708;

in one embodiment, determining whether the body panel and the edge intersect is performed by:

multiplying the normal vector and the direction vector to obtain a vector product; if the vector product is a first designated threshold, determining that the edge and the human body patch are not intersected; otherwise, determining that the edge is intersected with the human body patch.

If the product of the normal vector of the human body patch and the direction vector of the edge is 0, it indicates that the normal vector of the human body patch is perpendicular to the direction vector of the edge, and since the normal vector is perpendicular to the human body patch and the direction vector is parallel to the edge, it is determined that the edge is parallel to the human body patch, that is, the edge is not intersected with the human body patch, otherwise, it is determined that the edge is intersected with the human body patch.

Step 704: determining the occurrence of die punching of the clothing vertex and the three-dimensional human body model, and updating the die punching times of the edge;

in this embodiment, each edge has a corresponding number of times of puncturing, and the initial number of times of puncturing in this embodiment is 0, and each time the edge and one human body panel are punctured, the number of times of puncturing of the edge is added by 1 until the traversal of each human body panel is completed, so as to obtain the number of times of puncturing of the edge.

Step 705: judging whether each human body patch which is not traversed and intersects with the target garment patch exists, if so, returning to the step 702, and if not, executing the step 706;

step 706: judging whether each side which is not traversed exists, if so, returning to the step 701, otherwise, executing the step 707;

step 707: determining a die punching type based on the die punching times of each edge;

the pattern-through type includes a vertex pattern-through and an edge pattern-through, where the vertex pattern-through is a garment vertex located inside the three-dimensional human body model among garment vertices of the garment model, as shown in fig. 8, the vertex pattern-through is a schematic diagram of vertex pattern-through, a gray geometric body in the diagram is a patch of the three-dimensional human body model, and a vertex p _i And a vertex p _j All are the vertices on the clothing model, as can be seen in fig. 8, the vertex p _i And a vertex p _j Located in a patch of the three-dimensional phantom, the vertex p _i And vertex p _j The corresponding die-through type is the vertex die-through.

And the edge-through model is that the vertex of the clothing model is positioned outside the three-dimensional human body model, but the edge of the surface patch of the clothing model intersected with the surface patch of the human body exists in the clothing model. As shown in FIG. 9, the gray region is a three-dimensional phantom patch, with vertex p _i And vertex p _j Is a vertex on a patch of a clothing model, and the vertex p _i And a vertex p _j Located outside the three-dimensional human body model, but with the vertex p _i And a vertex p _j Edge e of _ij Is located inside the three-dimensional phantom, and as can be seen in fig. 9, edge e _ij Is not visible. Next, a mode of determining the die-punching type based on the die-punching times of each side is as follows:

and (4) vertex die penetration: and if the die punching times of each edge intersected with the human body surface patch are all first specified times, determining that the die punching type is vertex die punching.

Edge piercing: and if the sides intersected with the human body surface patches have sides with the die-punching times being second specified times, determining that the die-punching type is side die-punching, wherein the second specified times are more than the first specified times.

The first designated number of times in this embodiment is 1 time, and the second designated number of times in this embodiment is 2 times.

Step 708: judging whether each human body patch which is not traversed and intersects with the target garment patch exists, if so, returning to the step 702, otherwise, executing the step 709;

step 709: judging whether each side which is not traversed exists, if so, returning to execute the step 701, and if not, executing the step 710;

step 710: and determining that the clothing vertex and the three-dimensional human body model are not penetrated.

And if the clothing vertex and the three-dimensional human body model are determined not to be penetrated, the clothing vertex is not processed.

Step 504: and if the clothing vertex is determined to be subjected to die punching, determining the target position of the clothing vertex by using a target position determining mode corresponding to the die punching type, and moving the clothing vertex to the target position.

In one embodiment, the target position of the garment vertex is determined by two ways:

the method I comprises the following steps: and if the mode penetrating type is the vertex mode penetrating.

As shown in fig. 10, a schematic flowchart of determining the target position of the garment vertex when the type of the through-mold is vertex through-mold includes the following steps:

step 1001: determining a first displacement weight vector according to the positions of the intersecting vertexes of the edges connected with the clothing vertexes and the human body surface patches in the clothing model and the positions of the clothing vertexes;

a specific way of determining the first position weight is described below, and as shown in fig. 11, a schematic flow chart of determining the first displacement weight vector includes the following steps:

step 1101: for any intersecting vertex, subtracting the position of the intersecting vertex from the position of the clothing vertex to obtain a position difference;

step 1102: multiplying the position difference by a transposed vector of a normal vector of a target human body patch corresponding to the intersecting vertex to obtain a projection sub-vector, wherein the target human body patch is the human body patch where the intersecting vertex is located; wherein the projection subvector may be determined by equation (1):

wherein,

projection subvectors, x, corresponding to intersecting vertices _p Is the location of the intersecting vertices, x is the location of the garment vertices,

and the normal vectors of the target human body patches corresponding to the intersected vertexes are obtained.

It should be noted that: x in the present embodiment _p X and

all are 3 x 1 vectors.

Step 1103: obtaining projection vectors based on the projection sub-vectors corresponding to the intersecting vertexes;

in this embodiment, the number of intersecting vertices may be one or more, as shown in fig. 12, which is the case where the number of intersecting vertices is 1, x _p Are the intersecting vertices, x is the garment vertex,

is the normal vector of the human body patch F. When the intersection vertex is one, determining the projection sub-vector of the intersection vertex as the projection vector.

As shown in fig. 13, in the case where the intersection vertices are plural, fig. 13 shows the case where the intersection vertices include four, in which the clothing vertex x is respectively the intersection vertex with the body panel F1, the intersection vertex with the body panel F2, the intersection vertex with the body panel F3, and the intersection vertex with the body panel Fk. When the intersecting vertex is multiple, the projection vector is determined based on the projection sub-vector of each intersecting vertex. For example, the projection sub-vectors that result in four addition vertices are

And

then the projection vector is obtained as

Step 1104: and dividing the projection vector by a first target value to obtain the first displacement weight vector, wherein the first target value is obtained according to the normal vector of each human body patch intersected with each edge and the transposed vector of the normal vector.

The first target value can also be determined by the following two ways:

(1) And if the number of the intersected vertexes is one, multiplying the normal vector of the human body patch corresponding to the intersected vertex by the transposed vector of the normal vector to obtain the first target value.

And the human body surface slice corresponding to the intersecting vertex is the human body surface slice where the intersecting vertex is located.

(2): and if the number of the intersecting vertexes is multiple, multiplying a target normal phasor formed by each normal vector of each human body patch corresponding to each intersecting vertex by a target transposed normal vector formed by each transposed vector of each normal vector to obtain the first target value.

For example, if each normal vector of each human body patch corresponding to each intersecting vertex is

And

and the transposed vectors of each normal vector are respectively

And

then determine the target normal vector as

Target transpose normal vector of

Step 1002: obtaining a first intermediate position based on the first displacement weight vector and the normal vector of each human body patch;

step 1003: and adding the first middle position and the position of the clothing vertex to obtain the target position of the clothing vertex.

If the number of the intersected vertexes is one, obtaining the target position of the clothing vertex through a formula (2):

wherein x' is the target position of the clothing vertex, x is the position of the clothing vertex,

and gamma is the first displacement weight vector.

If the number of the intersected vertexes is multiple, determining the target position of the clothing vertex through a formula (3):

wherein,

is the normal vector of each human body patch in which each intersecting vertex is positioned,

is the first displacement weight vector.

The second method comprises the following steps: if the die-through type is edge die-through.

As shown in fig. 14, a schematic flow chart of determining the target position of the garment vertex when the type of the through-mold is the edge-through-mold includes the following steps:

step 1401: aiming at any edge with the second specified times of mode crossing, determining a second displacement weight vector based on the position of the edge and the position of the intersection line of each mode crossing human body surface patch, wherein the mode crossing human body surface patches are each human body surface patch intersected with the edge;

for example, as shown in fig. 15, the body panels F1 and F2 are body panels that are punched with the edge AB, i.e., the body panels F1 and F2 are punched body panels, and the edge p ₁ p ₂ Is the intersecting line of each perforating mould human body surface sheet.

In one embodiment, the second displacement weight vector is determined by: obtaining the shortest distance between the edge and the intersection line according to the position of the edge and the position of the intersection line; multiplying the direction vector of the target common vertical line of the side by the transposed vector of the direction vector to obtain a second target value; and dividing the shortest distance by the second target value to obtain the second displacement weight vector.

Step 1402: multiplying the second displacement weight vector of each side with the direction vector of each target common perpendicular line to obtain a second middle position, wherein any one target common perpendicular line is a common perpendicular line between any one side and the intersection line corresponding to the side; wherein the second intermediate position is obtainable by equation (4):

wherein x is ₂ In order to be said second intermediate position,

the direction vector of the target drooping saliva is shown,

a second vector of shift weights for each edge.

Step 1403: and adding the second middle position and the position of the clothing vertex to obtain the target position of the clothing vertex.

It should be noted that: the second intermediate position and the position of the garment vertex are both represented by a vector.

In order to ensure accuracy, after step 504 is executed, whether vertices where the mold penetration occurs still exist in each intersection region is judged, if not, the step of detecting each human body patch intersected with the clothing patch of the target object in the three-dimensional human body model of the target object is executed, and an intersection pair set is obtained until it is determined that each human body patch intersected with the patch of the target object does not exist in the three-dimensional human body model.

Because intersection detection can only detect mutually intersected patches, if three edges of a garment patch are in the three-dimensional human body model, the intersection detection cannot be detected. Therefore, the garment patches trapped inside the three-dimensional human body model need to be continuously pulled out in an iterative mode. As shown in fig. 16, the area formed by the black solid line in the figure is a patch of the three-dimensional human body model, and the dotted line represents an edge of the garment patch, as can be seen from the image (a) in fig. 16, the garment vertices a, B, C, and D are recessed in the three-dimensional human body model, and after the steps 501 to 504 in this embodiment are performed once, the image (B) is obtained, then after the steps 501 to 504 in this embodiment are performed again on the image (B), the image (C) is obtained, and finally, after the steps 501 to 504 in this embodiment are performed on the image (C), the image (D) is obtained. Namely, the top points of the invaginated clothes are all pulled out.

In order to further connect the technical solution in the present application, the following detailed description with reference to fig. 17 may include the following steps:

step 1701: detecting each human body patch intersected with a clothing patch of a target object in a three-dimensional human body model of the target object to obtain an intersected pair set, wherein any intersected pair in the intersected pair set comprises a pair of intersected human body patches and clothing patches;

step 1702: for any one clothing surface patch in the intersecting pair set, if the clothing surface patch and any other clothing surface patch in the intersecting pair set have the same edge, determining that the other clothing surface patch is the clothing surface patch adjacent to the clothing surface patch;

step 1703: fusing the clothing surface patch with the other clothing surface patches based on the same edge to obtain the intersection area;

step 1704: aiming at any clothing vertex in any intersection area, obtaining each edge connected with the clothing vertex in the clothing model, and determining whether the clothing vertex is subjected to die punching with the three-dimensional human body model and the die punching type or not based on the position of each edge and the position of each human body surface piece intersected with a target clothing surface piece, wherein the target clothing surface piece is each clothing surface piece forming the intersection area;

step 1705: if the clothing vertex is determined to be subjected to die punching, and the die punching type is vertex die punching, determining a first displacement weight vector according to the positions of the intersecting vertexes of each edge connected with the clothing vertex and each human body surface patch in the clothing model and the positions of the clothing vertexes;

step 1706: obtaining a first intermediate position based on the first displacement weight vector and the normal vector of each human body patch;

step 1707: adding the first middle position and the position of the clothing vertex to obtain the target position of the clothing vertex;

step 1708: if the mode punching is determined to occur at the clothing vertex, and the mode punching type is edge mode punching, determining a second displacement weight vector aiming at any edge with the mode punching times as second specified times based on the position of the edge and the position of the intersection line of each mode punching human body surface piece, wherein the mode punching human body surface piece is each human body surface piece intersected with the edge;

step 1709: multiplying the second displacement weight vector of each side with the direction vector of each target common perpendicular line to obtain a second middle position, wherein any one target common perpendicular line is a common perpendicular line between any one side and the intersection line corresponding to the side;

step 1710: adding the second middle position and the position of the clothing vertex to obtain the target position of the clothing vertex;

step 1711: moving the garment vertex to the target location.
