The terms "first," "second," "third," "fourth" and the like in the description and in the claims and in the above drawings, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments described herein may be implemented in other sequences than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, 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 or inherent to such process, method, article, or apparatus.
For easy understanding, the following describes a specific flow of an embodiment of the present invention, referring to fig. 1, and an embodiment of a cutting method based on a fantasy engine in the embodiment of the present invention includes:
101. Displaying a virtual world picture, mapping a target control object in the real world into the virtual world picture to obtain a virtual control object, wherein the virtual world picture comprises the virtual control object, a virtual object to be cut and a virtual cutting tool, and the virtual cutting tool changes along with the virtual control object;
the terminal displays a virtual world picture at least comprising a virtual object to be cut and a virtual cutting tool, and maps a target control object in the real world into the virtual world picture to obtain the virtual control object, wherein the virtual cutting tool can rotate, move and the like along with the virtual control object.
It should be noted that the virtual world is a world that an application program presents when running on a terminal, and the virtual world may be a simulation world of a real world, a semi-simulation and semi-imaginary world, or a pure imaginary world. The virtual control object, the virtual object to be cut, and the virtual cutting tool refer to movable objects in the virtual world, and the movable objects may be virtual animals, virtual plants, virtual characters, etc., for example, animals, plants, walls, stones, etc., displayed in the virtual world. In this embodiment, the virtual control object is a virtual hand, the virtual object to be cut is a stick, and the virtual cutting tool is an art designer. In other embodiments, the virtual control object may be a virtual character, the virtual object to be cut may be paper, glass, or the like, and the virtual cutting tool may be a saw, or the like, and the virtual control object, the virtual object to be cut, and the virtual cutting tool are not particularly limited.
The terminal maps a target control object (user's hand) in the real world into a virtual world picture using a illusion engine (unreal engine, UE 4) and renders in the virtual world picture, thereby generating a virtual control object (virtual hand) in the virtual world picture. In addition, the virtual world picture also comprises a virtual object to be cut (stick) and a virtual cutting tool (art designer).
It is to be understood that the execution body of the present invention may be a cutting device based on a fantasy engine, and may also be a terminal or a server, which is not limited herein. The embodiment of the invention is described by taking the terminal as an execution main body as an example.
102. Real behavior data of a target control object are obtained in real time from the real world, and the real behavior data are mapped into virtual behavior data of a virtual control object through a virtual engine;
the terminal acquires real behavior data from the target control object in real time from the real world, and then maps the real behavior data into the virtual world in real time through the UE4, thereby obtaining virtual behavior data.
In the present embodiment, the virtual behavior data includes the movement behavior of the virtual control object, such as a loop movement, a left shift, a right shift, and the like. When the user's hand makes a circular motion in the real world, the terminal maps the motion into the virtual world through the UE4, or when the user's hand translates left or right in the real world, the terminal maps the motion into the virtual world through the UE4, thereby mapping the real behavior data of the target control object (the user's hand) in the real world to the virtual control object in the virtual world, resulting in virtual behavior data.
103. Calculating cutting data according to the virtual behavior data, the virtual control object, the virtual cutting tool and the virtual object to be cut, wherein the cutting data is virtual surrounding cutting data or virtual translation cutting data;
The terminal calculates virtual surrounding cutting data or virtual translation cutting data according to the virtual behavior data, the virtual control object, the virtual cutting tool and the virtual object to be cut.
It should be noted that in this embodiment, there are two cutting modes of the virtual cutting tool (artist knife) in the virtual world picture, one is a surrounding cutting, that is, the virtual cutting tool (virtual cutting tool) cuts around the virtual object to be cut (stick) under the driving of the virtual control object (virtual hand); the other is translational cutting, namely, cutting is performed on the surface of a virtual object to be cut (wood stick) in a translational manner under the drive of a virtual control object (virtual hand). The virtual cutting tool is specifically determined according to the virtual behavior data.
The terminal judges which cutting mode is adopted specifically when the virtual object to be cut (stick) is cut according to the virtual behavior data, and when the virtual behavior data corresponds to the surrounding cutting, the terminal calculates virtual surrounding cutting data according to the virtual control object (virtual hand), the virtual cutting tool (art designing knife) and the virtual object to be cut (stick); when the virtual behavior data corresponds to the translational cutting, the terminal calculates virtual translational cutting data according to the virtual control object (virtual hand), the virtual cutting tool (art designing knife) and the virtual object to be cut (stick).
104. And cutting the virtual object to be cut according to the virtual surrounding cutting data and the corresponding surrounding cutting mode, or cutting the virtual object to be cut according to the virtual translation cutting data and the corresponding translation cutting mode.
The terminal performs surrounding cutting on the virtual object to be cut according to the virtual surrounding cutting data or performs translation cutting on the virtual object to be cut according to the virtual translation cutting data.
For example, in one embodiment, assuming that the virtual surround cut data is-30 °, the terminal performs surround cut according to the virtual surround cut data of-30 °. Wherein a "-" preceding 30 ° is used to indicate the direction of rotation at the time of the round cutting, in this embodiment, "+" or no sign indicates the round cutting clockwise around the virtual object to be cut (stick), and "-" indicates the round cutting counterclockwise around the virtual object to be cut (stick). In other embodiments, "+" and no designation may represent counter-clockwise wrap-around cuts, and "-" may represent clockwise wrap-around cuts, as not specifically limited. In another embodiment, assuming that the virtual translational cutting data is 5cm, the terminal performs translational cutting according to the virtual translational cutting data of 5 cm. The virtual translation cutting data may also be-5 cm, and the sign "-" in front of the cutting value is used to indicate the cutting direction, in this embodiment, when the sign is not in front of the cutting value or is "+", the cutting is performed toward the handle of the utility knife, and when the sign is "-" in front of the cutting value, the cutting is performed toward the opposite direction of the handle of the utility knife. In other embodiments, the symbols "+" and "no symbol" may represent cuts in opposite directions to the utility knife handle, and "-" may represent cuts in directions to the utility knife handle, as not specifically limited.
It should be noted that, in the process of encircling cutting, the knife handle of the art designing knife faces to the virtual hand in real time.

It should be noted that the virtual world is a world that an application program presents when running on a terminal, and the virtual world may be a simulation world of a real world, a semi-simulation and semi-imaginary world, or a pure imaginary world. The virtual control object, the virtual object to be cut, and the virtual cutting tool refer to movable objects in the virtual world, and the movable objects may be virtual animals, virtual plants, virtual characters, etc., for example, animals, plants, walls, stones, etc., displayed in the virtual world.

In addition, the virtual world picture also comprises a virtual object to be cut (stick) and a virtual cutting tool (art designer).
202. Real behavior data of a target control object are obtained in real time from the real world, and the real behavior data are mapped into virtual behavior data of a virtual control object through a virtual engine;

203. Calculating cutting data according to the virtual behavior data, the virtual control object, the virtual cutting tool and the virtual object to be cut, wherein the cutting data is virtual surrounding cutting data or virtual translation cutting data;
The terminal calculates virtual surrounding cutting data or virtual translation cutting data according to the virtual behavior data, the virtual control object, the virtual cutting tool and the virtual object to be cut.
It should be noted that in this embodiment, there are two cutting modes of the virtual cutting tool (artist knife) in the virtual world picture, one is a surrounding cutting, that is, the virtual cutting tool (virtual cutting tool) cuts around the virtual object to be cut (stick) under the driving of the virtual control object (virtual hand); the other is translational cutting, namely, cutting is performed on the surface of a virtual object to be cut (wood stick) in a translational manner under the drive of a virtual control object (virtual hand). The virtual cutting tool is specifically determined according to the virtual behavior data.
The terminal judges which cutting mode is adopted specifically when the virtual object to be cut (stick) is cut according to the virtual behavior data, and when the virtual behavior data corresponds to the surrounding cutting, the terminal calculates virtual surrounding cutting data according to the virtual control object (virtual hand), the virtual cutting tool (art designing knife) and the virtual object to be cut (stick); when the virtual behavior data corresponds to the translational cutting, the terminal calculates virtual translational cutting data according to the virtual control object (virtual hand), the virtual cutting tool (art designing knife) and the virtual object to be cut (stick).
Specifically, when virtual behavior data corresponds to surrounding cutting, the terminal firstly creates a first virtual arrow component with a positive direction pointing to the normal vector direction of the cutting surface on a virtual object to be cut and creates a first virtual tool component on a virtual cutting tool; secondly, the terminal reads coordinates of a virtual control object and coordinates of a first virtual tool component in real time from the virtual behavior data to obtain first virtual object coordinates and first virtual component coordinates; then, the terminal makes a perpendicular to the direction of the straight line where the normal vector is located by taking the first virtual control object coordinate as an origin through the UE4 to obtain a first surrounding cutting intersection point, and reads to obtain a first surrounding cutting intersection point vector; the terminal then uses the first virtual component coordinate as an origin through the UE4, makes a perpendicular to the direction of the straight line where the normal vector is located, obtains a second surrounding cutting intersection point, and reads and obtains a second surrounding cutting intersection point vector; the terminal calculates an included angle between the first surrounding cutting intersection point vector and the second surrounding cutting intersection point vector to obtain a first surrounding cutting included angle value, and carries out cross multiplication calculation on the first surrounding cutting intersection point vector and the normal vector direction to obtain a first included angle mark for indicating the rotation direction of the first virtual tool component; and finally, the terminal combines the first surrounding cutting included angle value and the first included angle mark to determine virtual surrounding cutting data.
The method comprises the steps that a first virtual arrow component is firstly established on a virtual object to be cut (a wood stick) by a terminal, wherein the direction pointed by an arrow of the first virtual arrow component is a positive direction, the positive direction of the first virtual arrow component points to the normal vector direction of a cutting surface, and meanwhile, the coordinates of a virtual control object (a virtual hand) are read from virtual behavior data in real time, namely, the coordinates of the first virtual object; the terminal also creates a first virtual tool component (empty component) on the virtual cutting tool (art designer) and reads the coordinates of the component in real time to obtain the first virtual component coordinates; determining an intersection point after the first virtual object coordinate is taken as an origin to a straight line in a normal vector direction by using FindClosestPointonLine functions in the UE4, namely a first surrounding cutting intersection point, and then reading to obtain a vector of the first surrounding cutting intersection point, namely a vector of the first surrounding cutting intersection point; meanwhile, the terminal uses the function to determine an intersection point after the first virtual component coordinate is taken as an origin and a perpendicular line is drawn to a straight line where a normal vector direction is located, namely a second surrounding cutting intersection point, and reads a vector of the second surrounding cutting intersection point, namely a vector of the second surrounding cutting intersection point; the terminal performs point multiplication and inverse cosine function solving calculation on the first surrounding cutting intersection point vector and the second surrounding cutting intersection point vector to obtain a first surrounding cutting included angle value, and then performs cross multiplication calculation on the normal vector direction of the first surrounding cutting intersection point vector to obtain a first included angle mark ("+" or "-") for indicating the rotation direction of the first virtual tool assembly; and finally, the terminal combines the first included angle mark and the first surrounding cutting included angle value to determine virtual surrounding cutting data. For example, the calculated first surrounding cutting angle value is 30 ° and the calculated first angle is identified as "-", and the terminal obtains virtual surrounding cutting data of-30 °.
When the virtual behavior data corresponds to the translation cutting, the method specifically comprises the following steps of:
The terminal firstly creates a second virtual tool component and a second virtual arrow component with the positive direction pointing to the normal vector direction of the cutting surface on the virtual object to be cut, and simultaneously reads the coordinates of the virtual control object and the second virtual tool component from the virtual behavior data in real time to obtain a second virtual object coordinate and a second virtual component coordinate; the terminal uses the second virtual component coordinate as an origin through the illusion engine, and makes a perpendicular to a straight line where the normal vector direction is located, so as to obtain a first translation cutting intersection point, and reads and obtains the first translation cutting intersection point coordinate; the terminal also uses a second virtual object coordinate as an origin through the illusion engine, makes a perpendicular to a straight line where the normal vector direction is located, obtains a second translation cutting intersection point, and reads and obtains a second translation cutting intersection point coordinate; calculating a translation cutting displacement vector by combining the first translation cutting intersection point coordinate and the second translation cutting intersection point coordinate, and calculating the displacement vector through a preset length function to obtain a displacement length; and performing point multiplication calculation on the translation cutting displacement vector and the normal vector direction to obtain a displacement mark, and finally determining virtual translation cutting data by combining the displacement mark and the displacement length.
The terminal firstly establishes a second virtual tool component and a second virtual arrow component on a virtual object to be cut (stick), wherein the arrow of the second virtual arrow component is a positive direction, the positive direction of the first virtual arrow component points to the normal vector direction of the cutting surface, and simultaneously, the coordinates of a virtual control object (virtual hand) and the second virtual tool component, namely the coordinates of the second virtual object and the coordinates of the second virtual component, are read in real time from virtual behavior data; the terminal uses the UE4 engine to draw a perpendicular to a straight line in which the second virtual component coordinate is located in the normal vector direction as an origin, determines a first translation cutting intersection point, reads and obtains a first translation cutting intersection point coordinate, and uses the second virtual object coordinate as the origin to draw a perpendicular to a straight line in which the normal vector direction is located, determines a second translation cutting intersection point, and reads and obtains a second translation cutting intersection point coordinate; calculating displacement vectors of the first translational cutting intersection point coordinate and the second translational cutting intersection point coordinate through a UE4 engine to obtain translational cutting displacement vectors, and calculating the translational cutting displacement vectors through VectorLength functions in the UE engine to obtain lengths of the displacement vectors, namely displacement lengths; and the terminal performs dot product calculation on the translation cutting displacement vector and the normal vector direction to obtain a displacement identifier, and finally, virtual translation cutting data are determined by combining the translation cutting displacement vector and the displacement identifier. The displacement identifier may be represented by "+" or "-" and, for example, the calculated displacement length is 5cm, the calculated displacement identifier is "+", and the terminal obtains virtual translation cutting data +5cm or 5cm.
204. Cutting the virtual object to be cut according to the virtual surrounding cutting data or the virtual translation cutting data and the corresponding cutting mode;
The terminal cuts the virtual object to be cut according to the virtual surrounding cutting data or cuts the virtual object to be cut in a translation mode according to the virtual translation cutting tool.
For example, in one embodiment, assuming that the virtual surround cut data is-30 °, the terminal performs surround cut according to the virtual surround cut data of-30 °. Wherein a "-" preceding 30 ° is used to indicate the direction of rotation at the time of the round cutting, in this embodiment, "+" or no sign indicates the round cutting clockwise around the virtual object to be cut (stick), and "-" indicates the round cutting counterclockwise around the virtual object to be cut (stick). In other embodiments, "+" and no designation may represent a counter-clockwise wrap-around cut, and "-" may represent a clockwise wrap-around cut, or the designations "1" and "0" may be used to distinguish the direction of the wrap-around cut, as not specifically limited. In another embodiment, assuming that the virtual translational cutting data is 5cm, the terminal performs translational cutting according to the virtual translational cutting data of 5 cm. The virtual translation cutting data may also be-5 cm, and the sign "-" in front of the cutting value is used to indicate the cutting direction, in this embodiment, when the sign is not in front of the cutting value or is "+", the cutting is performed toward the handle of the utility knife, and when the sign is "-" in front of the cutting value, the cutting is performed toward the opposite direction of the handle of the utility knife. In other embodiments, the symbols "+" and "no symbol" may represent cuts in opposite directions to the utility knife handle, and "-" may represent cuts in directions to the utility knife handle, or the identification "1" and "0" may be used to distinguish between cuts of translational cuts, as not specifically limited.
It should be noted that, when the translation cutting is performed, a cutting range is preset, so that the virtual cutting tool (art designing knife) is suspended at a portion beyond the cutting range, and the virtual cutting tool (wood stick) is contacted with the virtual object to be cut (wood stick) at the portion within the cutting range.
205. Calculating a target included angle termination value according to the virtual object to be cut, and judging whether to terminate surrounding cutting of the virtual object to be cut or not based on the target included angle termination value;
and the terminal calculates a target included angle termination value for judging whether to terminate surrounding cutting of the virtual object to be cut according to the virtual object to be cut.
Specifically, the terminal creates a third virtual tool component on a virtual object to be cut (a wood stick), and reads the coordinates of the third virtual tool component to obtain the coordinates of the third virtual component; secondly, the terminal makes a perpendicular line to a straight line where a normal vector direction is located by taking a third virtual component coordinate as an origin through a UE4 engine to obtain a third surrounding cutting intersection point, and reads to obtain a third surrounding cutting intersection point vector; then the terminal multiplies the normal vector of the included angle with the normal vector to obtain a second included angle mark; the terminal combines the second included angle mark and the second included angle value to determine an initial included angle termination value; and finally, calculating the initial included angle termination value by adopting an inverse cosine function to obtain a target included angle termination value.
It should be noted that the initial angle end value generally belongs to [ -180, 180], and the terminal uses a cosine function to convert the initial angle end value to between [0,1 ]. Assuming an initial included angle termination value of-60 deg., the target included angle termination value is 0.5.
206. And if the target included angle termination value is greater than the termination threshold value, terminating the surrounding cutting of the virtual object to be cut.
If the target included angle end value is smaller than or equal to the final threshold value, calculating virtual surrounding cutting data continuously, and performing surrounding cutting on the virtual object to be cut (wood stick) based on the virtual surrounding cutting data.
Assuming that the termination threshold is 0.99 and the calculated target included angle termination value is 1, it indicates that the virtual cutting tool (art knife) completes the surrounding cutting, and at this time, the virtual object to be cut is terminated to perform the surrounding cutting, if the calculated target included angle termination value is 0.5, it indicates that the virtual cutting tool (art knife) does not complete the surrounding cutting yet, and the terminal needs to continue calculating virtual surrounding cutting data and performing the surrounding cutting on the virtual object to be cut (stick).
According to the embodiment of the invention, the virtual surrounding cutting data or the virtual translation cutting data are calculated according to the virtual behavior data, the virtual control object, the virtual cutting tool and the virtual object to be cut, and the virtual object to be cut is subjected to surrounding cutting according to the virtual surrounding cutting data or is subjected to translation cutting according to the virtual translation cutting data, so that the integrity of a cutting picture is improved and the cutting effect is optimized.
