Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 2 to 4, the present embodiment provides a method for preventing mold penetration during merging of three-dimensional models. The method for preventing the three-dimensional model from penetrating the model during merging can be applied to replacing parts such as clothes, heads and the like for different three-dimensional models in games, can effectively avoid the three-dimensional model from penetrating the model without calculation of a physical engine, reduces the data operation amount, and can greatly reduce the performance requirement on equipment.
As shown in fig. 2, the method for preventing mold penetration during merging of three-dimensional models includes the following steps:
and S101, acquiring the parts to be merged according to the merging instruction.
The system is internally stored with a three-dimensional model and more than two different components, and the merging instruction can be input from the outside through an input device or can be automatically produced by the system.
S102, replacing the parts for the three-dimensional model, and deleting the parts covered by the parts in the three-dimensional model.
Wherein the three-dimensional model comprises a plurality of parts, each part in the three-dimensional model is combinable, and the part is combined with the minimum granularity. The three-dimensional model may be a character model in a game that may be generated by a 3D physics engine, such as a character model generated from a Spine skeleton model in one embodiment, which may include parts of the head, body, arms, legs, etc. The parts may also comprise a plurality of different parts, for example, the parts of the character model may comprise any one or more combinations of clothing, jewelry, weapons, ornaments, including any one or more combinations of hats, clothing, pants, shoes, bodies, sleeves, collars, the top may be subdivided into bodies (top bodies), sleeves, etc., and the pants may be subdivided into sub-units such as trouser legs, waist of trousers, etc., as desired. The ornament may be a piece of jewelry worn, such as a bracelet, necklace, ring, or may be a flower worn on the head, etc. When the component is a garment, the garment may be a full body garment comprising the three-dimensional model, for example garments including headwear, tops, trousers and shoes. In other embodiments the garment may also be a partial garment of a different part of the three-dimensional model, for example the garment is only a sleeve, a belt or a hat.
In some embodiments, the three-dimensional model may also be a pet model or an equipment model in a game, and the component may be a wig, an accessory, and a decoration for decorating the pet model or the equipment model.
In step S102, replacing the component for the three-dimensional model is to merge the component into the three-dimensional model, for example, putting on a garment for the three-dimensional model (i.e., merging). The removing of the portion of the three-dimensional model that is covered by the component may be performed after replacing the component for the three-dimensional model. In some embodiments, the part to be covered by the component after the three-dimensional model is merged may be calculated, the part to be covered by the component in the three-dimensional model may be deleted, and finally the three-dimensional model and the component may be merged to merge the component onto the three-dimensional model.
In the embodiment, when the part is replaced for the three-dimensional model, the part covered by the part in the three-dimensional model is deleted, so that the occurrence of die penetration of the part during the movement of the three-dimensional model is effectively avoided. In addition, the technical scheme avoids the die punching through the physical engine calculation, reduces the data operation amount and can greatly reduce the performance requirement on the equipment.
As shown in fig. 3, in one embodiment, it is provided how to replace the component with the three-dimensional model, and delete the part of the three-dimensional model covered by the component, which includes the steps of:
s201, presetting a component model corresponding to the component, wherein the component model comprises the component and an auxiliary model covered by the component.
Wherein the auxiliary model is provided for corresponding components, each component is provided with a corresponding auxiliary model, the auxiliary model is located inside the corresponding component (i.e. the garment is worn on the auxiliary model), and the auxiliary model is completely covered by the component. The three-dimensional model and the auxiliary model each include coordinate points and a plane composed of the coordinate points. For example, the component is a garment, and the garment model includes the garment and an auxiliary model covered by the garment, the auxiliary model being located within and completely covered by the garment.
S202, calculating the same part of the three-dimensional model as the auxiliary model.
Wherein the auxiliary model is the same as a part of the three-dimensional model, and therefore the same part of the auxiliary model and the three-dimensional model can be found by comparing the coordinate points.
S203, deleting the same part in the three-dimensional model.
S204, merging the three-dimensional model with the deleted same part and the part to merge the part on the three-dimensional model.
In this embodiment, the part of the three-dimensional model covered by the part is deleted by deleting the same coordinate point, so that a complicated three-dimensional perspective calculation is not required, and the performance requirement on the device can be greatly reduced in the model merging operation at the merging time in step S204.
In one embodiment, the three-dimensional model and the auxiliary model each include coordinate points and a plane formed by the coordinate points; the "calculating the same portion of the three-dimensional model as the auxiliary model" includes: and calculating the same coordinate points of the three-dimensional model and the auxiliary model and a surface consisting of the same coordinate points.
The "deleting the same portion in the three-dimensional model" includes: and deleting the same coordinate points and a surface formed by the same coordinate points in the three-dimensional model.
The surface formed by the same coordinate points can adopt three adjacent coordinate points to form a triangular surface. In other embodiments, the surface composed of the same coordinate points may also be a quadrilateral surface formed by four adjacent coordinate points.
In the above embodiments, the component comprises any one or more of a garment, a piece of jewelry, a weapon, and a decoration, and the garment comprises any one or more of a hat, a garment, a pair of trousers, a shoe, a body, a sleeve, and a collar.
In some embodiments, the component is an outfit, and the three-dimensional model when combined is combined with the outfit (i.e., the component), i.e., the three-dimensional model is worn or exchanged for an outfit that includes a coat and pants (and in some cases, may also include hats, shoes). In this case, therefore, the auxiliary model may be obtained by fitting the garment (i.e. the suit) on the three-dimensional model and then removing the parts of the three-dimensional model not covered by the garment.
In other embodiments, the component may be a more subdivided partial garment, for example, the coat may be subdivided into a body (i.e., a main body portion of the coat), a collar, sleeves, a waistband, etc., and the garment may be any one of a body, a collar, sleeves, a waistband, or a combination of a body and any one of a collar, sleeves, or a waistband. In this case, when the auxiliary model is created, a portion corresponding to the garment may be obtained from the three-dimensional model, and then a portion of the portion that is not covered by the garment may be deleted to obtain the auxiliary model. For example, when the garment is a sleeve, only the arm model at the position corresponding to the sleeve in the three-dimensional model is obtained, then the sleeve is put on the arm model, and the part of the arm model which is not covered by the sleeve is deleted, so that the remaining part of the model in the sleeve is the auxiliary model.
In some embodiments, the part combined with the three-dimensional model can also be hair, jewelry, luggage, weapons, or the like, so that the hair (i.e., hairstyle), jewelry, or different weapons carried by the three-dimensional model can be replaced by selecting different parts. The three-dimensional model can be a character object in a game, so that the character object can play different roles in the game by combining the three-dimensional model of the character object with different parts, and clothes, bags, hairs, ornaments, weapons and the like of the character object can be replaced.
Before combination, auxiliary models for making auxiliary models, such as three-dimensional models for wearing hats, shoes, trousers, various clothes, hair, jewelry, cases, weapons and the like, are preset. These pre-made auxiliary models are directly invoked when merging is required.
As shown in fig. 4, an arm is taken as the three-dimensional model 10, and a sleeve is taken as a garment 21 (i.e., a component). The three-dimensional arm model 10 includes coordinate points a, b, c, d, e, f, g, and h, and triangular surfaces (a, b, e), (b, e, f), (e, f, g), (f, g, h), (g, h, c), and (h, c, d) formed by these coordinate points. Sleeve garment 21 includes an auxiliary model 22 located within garment 21, auxiliary model 22 including coordinate points e, f, g, h, and triangular faces (e, f, g) and (f, g, h) made up of these coordinate points. The auxiliary model 22 is located inside the garment 21 and is completely covered by the garment 21. In step S202, coordinate points e, f, g, h of the auxiliary model 22 and the three-dimensional arm model 10 are found by comparing the coordinate points, and triangular surfaces (e, f, g) and (f, g, h) composed of the coordinate points e, f, g, h.
In step S203, coordinate points e, f, g, h in the three-dimensional arm model 10 and the composed triangular surfaces (e, f, g) and (f, g, h) may be deleted; coordinate points e, f, g, h and the composed triangular faces (e, f, g) and (f, g, h) deletions may proceed through the interface of the 3D physics engine.
In step S204, the three-dimensional arm model 10 from which the same portion has been deleted and the garment 21 are combined, so that the garment 21 is combined with the three-dimensional arm model 10. As shown in fig. 3, the combined garment 21 is worn on the arm three-dimensional model 10, and the part of the arm three-dimensional model 10 covered by the garment 21 is deleted, so that the phenomenon of mold penetration does not occur when the arm three-dimensional model moves.
The embodiment shown in fig. 4 is also applicable to parts such as hair, jewelry, weapons, etc., and the parts such as hair, jewelry, weapons, etc. also include corresponding auxiliary models. For example, when the component is hair, the hair component includes hair and an auxiliary model of hair that is a model of the head where it is covered by (or in contact with) the hair (the auxiliary model may also include a neck model when the hair is longer); when the component is a weapon, the weapon component comprises a weapon body and a weapon auxiliary model, and the weapon auxiliary model is a body model covered by the model. When non-clothing parts such as hair, jewelry, weapons and the like are combined with the three-dimensional model (namely when the parts are replaced or worn), the method is the same as the method for replacing sleeve parts, the same parts of the auxiliary model of the non-clothing parts and the three-dimensional model are calculated, then the parts of the three-dimensional model, which are the same as the auxiliary model, are deleted, and finally the non-clothing parts are combined on the three-dimensional model.
As shown in fig. 5, in one embodiment, a mold break-through prevention apparatus 400 is provided when three-dimensional models are merged. The anti-die-punching device 400 can be applied to replacing parts for different three-dimensional models in games when the three-dimensional models are combined, the anti-die-punching device 400 can effectively avoid die punching of the three-dimensional models when the three-dimensional models are combined, the die punching is avoided without physical engine calculation, the data operation amount is reduced, and the performance requirement on equipment can be greatly reduced. The three-dimensional model merging anti-punch device 400 comprises an obtaining module 410 and a merging module 420. The obtaining module 410 is configured to obtain a component to be merged according to a merging instruction. The merging module 420 is used for replacing the part for the three-dimensional model and deleting the part covered by the part in the three-dimensional model.
The system is internally stored with a three-dimensional model and more than two different components, and the merging instruction can be input from the outside through an input device or can be automatically produced by the system.
And the three-dimensional model includes a plurality of parts, each part in the three-dimensional model being mergeable, the parts being of a smallest granularity of merger. The three-dimensional model may be a character model in a game that may be generated by a 3D physics engine, such as a character model generated from a Spine skeleton model in one embodiment, which may include parts of the head, body, arms, legs, etc. The parts may also comprise a plurality of different parts, for example, the parts of the character model may comprise any one or more combinations of clothing, jewelry, weapons, ornaments, including any one or more combinations of hats, clothing, pants, shoes, bodies, sleeves, collars, the top may be subdivided into bodies (top bodies), sleeves, etc., and the pants may be subdivided into sub-units such as trouser legs, waist of trousers, etc., as desired. When the component is a garment, the garment may be a full body garment comprising the three-dimensional model, for example garments including headwear, tops, trousers and shoes. In other embodiments the garment may also be a partial garment of a different part of the three-dimensional model, for example the garment is only a sleeve, a belt or a hat.
In some embodiments, the three-dimensional model may also be a pet model or an equipment model in a game, and the garment is an ornament for decorating the pet model or the equipment model.
In the above embodiments, the component comprises any one or more of a garment, a piece of jewelry, a weapon, and a decoration, and the garment comprises any one or more of a hat, a garment, a pair of trousers, a shoe, a body, a sleeve, and a collar.
In some embodiments, the three-dimensional models are combined with the outfit (i.e., the component) when combined, i.e., the three-dimensional models are worn or replaced with an outfit that includes a coat and pants (and in some cases may also include hats, shoes). In this case, therefore, the auxiliary model may be obtained by fitting the garment (i.e. the suit) on the three-dimensional model and then removing the parts of the three-dimensional model not covered by the garment.
In other embodiments, the garment may be a more subdivided partial garment, for example, the coat may be subdivided into a body (i.e., a main body portion of the coat), a collar, sleeves, a waistband, etc., the garment may be any one of a body, a collar, sleeves, a waistband, or a combination of a body and any one of a collar, sleeves, or a waistband. In this case, when the auxiliary model is created, a portion corresponding to the garment may be obtained from the three-dimensional model, and then a portion of the portion that is not covered by the garment may be deleted to obtain the auxiliary model. For example, when the garment is a sleeve, only the arm model at the position corresponding to the sleeve in the three-dimensional model is obtained, then the sleeve is put on the arm model, and the part of the arm model which is not covered by the sleeve is deleted, so that the remaining part of the model in the sleeve is the auxiliary model.
In some embodiments, the component incorporated with the three-dimensional model may be hair, jewelry, luggage, weapons, or the like.
Before combination, auxiliary models for making auxiliary models, such as three-dimensional models for wearing hats, shoes, trousers, various clothes, hair, jewelry, cases, weapons and the like, are preset. These pre-made auxiliary models are directly invoked when merging is required.
As shown in fig. 6, in an embodiment, the merging module 420 includes a presetting module 421, a calculating module 422, a deleting module 423, and a merging submodule 424.
The presetting module 421 is configured to preset a component model corresponding to the component, where the component model includes the component and an auxiliary model covered by the component.
Wherein the auxiliary model is provided for corresponding components, each component is provided with a corresponding auxiliary model, the auxiliary model is located inside the corresponding component (i.e. the garment is worn on the auxiliary model), and the auxiliary model is completely covered by the component. The three-dimensional model and the auxiliary model each include coordinate points and a plane composed of the coordinate points.
The calculation module 422 is used to calculate the same part of the three-dimensional model as the auxiliary model. Wherein the auxiliary model is the same as a part of the three-dimensional model, and therefore the same part of the auxiliary model and the three-dimensional model can be found by comparing the coordinate points.
The deletion module 423 is configured to delete the same portion of the three-dimensional model.
The merge sub-module 424 is configured to merge the three-dimensional model from which the identical portion is deleted with the component to merge the component on the three-dimensional model.
In this embodiment, the part of the three-dimensional model covered by the part is deleted by deleting the same coordinate point, so that a complicated three-dimensional perspective calculation is not required, and the performance requirement on the device can be greatly reduced in the model merging operation at the merging time in step S204.
As shown in fig. 4, the three-dimensional model 10 is described with arms as an example and with sleeves as a garment 21. The presetting module 421 presets the three-dimensional arm model 10 and the sleeve garment 21, and the sleeve garment 21 includes an auxiliary model 22 inside the garment. The three-dimensional arm model 10 includes a, b, c, d, e, f, g, h coordinate points, and triangular surfaces (a, b, e), (b, e, f), (e, f, g), (f, g, h), (g, h, c), and (h, c, d) composed of these coordinate points. The auxiliary model 22 includes coordinate points e, f, g, h, and triangular faces (e, f, g) and (f, g, h) composed of these coordinate points. The auxiliary model 22 is located inside the garment 21 and is completely covered by the garment 21.
The calculating module 422 is configured to find out coordinate points e, f, g, and h of the auxiliary model 22 and the arm three-dimensional model 10, and triangle surfaces (e, f, g) and (f, g, and h) formed by the coordinate points e, f, g, and h through coordinate point comparison.
The deleting module 423 can delete the coordinate points e, f, g, h in the three-dimensional arm model 10 and the triangular surfaces (e, f, g) and (f, g, h) formed by the coordinate points e, f, g, h; coordinate points e, f, g, h and the composed triangular faces (e, f, g) and (f, g, h) deletions may proceed through the interface of the 3D physics engine.
The merge sub-module 424 performs a merge operation on the three-dimensional arm model 10 and the garment 21 from which the same portion is deleted, so that the garment 21 is merged on the three-dimensional arm model 10. As shown in fig. 3, the combined garment 21 is worn on the arm three-dimensional model 10, and the part of the arm three-dimensional model 10 covered by the garment 21 is deleted, so that the phenomenon of mold penetration does not occur when the arm three-dimensional model moves.
In this embodiment, when the merging module 420 replaces a component for the three-dimensional model, the part covered by the component in the three-dimensional model is deleted, so that the occurrence of die penetration of the component during the movement of the three-dimensional model is effectively avoided. In addition, the technical scheme avoids the die punching through the physical engine calculation, reduces the data operation amount and can greatly reduce the performance requirement on the equipment.
The embodiment shown in fig. 4 is also applicable to parts such as hair, jewelry, weapons, etc., and the parts such as hair, jewelry, weapons, etc. also include corresponding auxiliary models. For example, when the component is hair, the hair component includes hair and an auxiliary model of hair that is a model of the head where it is covered by (or in contact with) the hair (the auxiliary model may also include a neck model when the hair is longer); when the component is a weapon, the weapon component comprises a weapon body and a weapon auxiliary model, and the weapon auxiliary model is a body model covered by the model. When non-clothing parts such as hair, jewelry, weapons and the like are combined with the three-dimensional model (namely when the parts are replaced or worn), the method is the same as the method for replacing sleeve parts, the same parts of the auxiliary model of the non-clothing parts and the three-dimensional model are calculated, then the parts of the three-dimensional model, which are the same as the auxiliary model, are deleted, and finally the non-clothing parts are combined on the three-dimensional model.
As shown in fig. 7, in an embodiment, a computer storage medium 700 is provided, on which a computer program is stored, and when the program is executed by a processor, the method for preventing a mold break when merging three-dimensional models according to any one of the above embodiments is implemented.
When the computer program in the computer storage medium replaces the part for the three-dimensional model, the part covered by the part in the three-dimensional model is deleted, so that the occurrence of part die penetration during the movement of the three-dimensional model is effectively avoided. In addition, the technical scheme avoids the die punching through the physical engine calculation, reduces the data operation amount and can greatly reduce the performance requirement on the equipment. Furthermore, the technical scheme deletes part of the three-dimensional model by deleting the same coordinate points in the three-dimensional model and the auxiliary model, so that complex three-dimensional perspective calculation is not needed, and the performance requirement on equipment can be greatly reduced in the model merging step during merging. And the part of the three-dimensional model covered by the part is deleted by deleting the same coordinate point, so that complex three-dimensional perspective calculation is not needed, and the performance requirement on the equipment can be greatly reduced in the model merging operation during merging in the step S204.
It should be noted that, although the above embodiments have been described herein, the invention is not limited thereto. Therefore, based on the innovative concepts of the present invention, the technical solutions of the present invention can be directly or indirectly applied to other related technical fields by making changes and modifications to the embodiments described herein, or by using equivalent structures or equivalent processes performed in the content of the present specification and the attached drawings, which are included in the scope of the present invention.
