The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," or "having," and any variations thereof, are intended to cover non-exclusive inclusions, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
For convenience of understanding, a specific flow of the embodiment of the present invention is described below, and referring to fig. 1, a first embodiment of a ribbon binding simulation method in the embodiment of the present invention includes:
101. constructing a simulation object to obtain a bandage skeleton model;
it is understood that the execution main body of the invention may be a band binding simulation device, and may also be a terminal or a server, which is not limited herein. The embodiment of the present invention is described by taking a server as an execution subject.
In this embodiment, the simulation of the band tying is implemented in the virtual reality space, a simulation object of the band is first constructed, and here, a band skeleton model of the simulation object is constructed by using UE4 (umregl engime 4, illusion 4 engine), where the band skeleton model is composed of a plurality of band skeletons, and each band skeleton has a fixed length, and the total length of the band skeleton model is obtained by combining the skeleton skeletons. For example, the belted bone model consists of 100 pieces of belted bone, and each piece of belted bone has a length of 0.29cm, and the length of the belted bone model is 29 cm. The bones of the bandage can be shaped in a specific way by changing the rotation angle of the bones in real time during the binding of the bandage into a specific shape.
102. And determining the length of each edge of the simulation object according to the bone length of the bandage bone model.
And determining the length of each edge of the simulation object according to the bone length of the bandage bone model, wherein the shape of the simulation object is not limited. For example, if the simulation object is a rectangle, the length of the long side of the rectangle is X, and the length of the wide side is Y. If the length of the bandage bone model is 29cm, 2X +2Y is less than or equal to 29 cm. If the cable tie skeleton model consists of 100 cable tie skeletons, one long side of the rectangle needs n sections of skeletons, and one wide side needs m sections of skeletons, then n + m is less than or equal to 100. n and m must be integers. n is X/0.29, and m is Y/0.29. (the results of n and m may be rounded up). After obtaining the results of n and m, it is checked whether 2n +2m ≦ 100 is true. If the length and the width are not reasonable, the ribbon is not operated. And if so, carrying out the next operation.
In another example, if the simulation object is an equilateral triangle, the length of each side is less than or equal to 1/3 times the length of the bone. Assume that each side of an equilateral triangle is Z in length. If the length of the bandage bone model is 29cm, the 3Z is less than or equal to 29 cm. If the bandage bone model consists of 100 bandage bones as described above, each side of the triangle needs q sections of bones, and 3q is less than or equal to 100. q must be an integer. q is Z/0.29. (the result of q may be rounded up) after the result of q is obtained, it is checked whether 3 q.ltoreq.100 holds. If the side length is not reasonable, the set side length is not reasonable, and the ribbon is not operated. And if so, carrying out the next operation.
In this embodiment, the ribbon binding simulation instruction of the ribbon bone model is actively triggered and sent by a user, and the triggering of the ribbon binding simulation instruction can be realized through a prop control, that is, through a user interface control, after the user carries vr (virtual Remlty) equipment, any visual control or element of a virtual space can be seen, such as a picture, an input frame, a text frame, a button, a label, a ribbon binding action and other controls, and the user interface control can respond to the operation of the user to perform a specified action in a corresponding band binding interval, so that the ribbon binding simulation instruction of the ribbon bone model can be triggered; the other method is that the behavior operation of the user is detected through the photographic equipment, and when the detected user is used as the preset action of the binding tape, the binding tape simulation instruction of the binding tape skeleton model can be triggered.
In addition, parameters of the simulation object in the simulation instruction are bound by the binding belt so as to describe the shape track and the size of the simulation object. The simulation object is formed by locally combining various different shapes or shapes, so that the simulation object needs to be cut into various simulation object units for describing a single shape, such as a linear equation, a circular equation, an elliptic equation, a spherical equation and the like. The simulation size of the simulation object may be expressed by calculating the length or diameter of each simulation object cell. The final shape of the bandage binding simulation can be obtained by limiting the shape and the length of the simulation object.
103. And obtaining the simulation form of the bandage bone model according to the length of each edge of the simulation object and the internal angle of the simulation object.
And after the length of each edge of the simulation object is calculated, obtaining the simulation form of the bandage bone model according to the internal angle of the simulation object. The internal angle of the simulation object can be preset. For example, if the simulation object is rectangular, the internal angle of the simulation object is 90 degrees. If the simulation object is an equilateral triangle, the internal angle of the simulation object is 60 degrees. The simulation object may also be in other shapes, and correspondingly, the internal angle may also be in other degrees, which is not limited herein.
After the length of each side of the simulation object and the internal angle of the simulation object are obtained, the simulation form of the bandage bone model can be obtained.
The invention provides a ribbon binding simulation method, which comprises the following steps: constructing a simulation object to obtain a bandage skeleton model; determining the length of each edge of the simulation object according to the bone length of the bandage bone model; and obtaining the simulation form of the bandage bone model according to the length of each edge of the simulation object and the internal angle of the simulation object, wherein the internal angle of the simulation object is preset. Therefore, the binding process of the binding belt can be simulated in the virtual reality, the binding belt can be bound into a shape with a specific simulation form, and the shape with the specific simulation form can be reproduced in the virtual reality.
