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 ease of understanding, a detailed flow of an embodiment of the present invention is described below, and referring to fig. 1, an embodiment of the ghost engine based segmentation method in an 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 a 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 a virtual control object, wherein the virtual cutting tool can rotate, move and other changes along with the virtual control object.
It should be noted that the virtual world is a world presented when the application program runs on the terminal, and the virtual world may be a simulated world of a real world, a semi-simulated semi-fictional world, or a purely fictional world. The virtual control object, the virtual object to be cut, and the virtual cutting tool refer to an object that is movable in a virtual world, and the movable object may be a virtual animal, a virtual plant, a virtual character, etc., for example, an animal, a plant, a wall, a stone, 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 a utility knife. 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 knife 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 uses a virtual engine (UE 4) to map a target control object (a user's hand) in the real world into a virtual world screen and renders the target control object in the virtual world screen, thereby generating a virtual control object (a virtual hand) in the virtual world screen. In addition, the virtual world picture also comprises a virtual object to be cut (a wooden stick) and a virtual cutting tool (an art knife).
It is to be understood that the execution subject of the present invention may be a cutting apparatus based on a ghost engine, 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 terminal as an execution subject.
102. Real behavior data of a target control object is obtained in real time from the real world, and the real behavior data is mapped into virtual behavior data of a virtual control object through a virtual engine;
the terminal acquires real behavior data from a 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, so as to obtain virtual behavior data.
In the present embodiment, the virtual behavior data includes the motion behavior of the virtual control object, such as a circling motion, a panning left, a panning right, and the like. When the hand of the user performs a circling motion in the real world, the terminal maps the motion into the virtual world through the UE4, or when the hand of the user translates left or right in the real world, the terminal maps the motion into the virtual world through the UE4, so as to map the real behavior data of the target control object (the hand of the user) 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 are virtual surrounding cutting data or virtual translation cutting data;
and 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, the virtual cutting tool (utility knife) in the virtual world picture has two cutting modes, one is circular cutting, that is, the virtual cutting tool (virtual cutting tool) is driven by the virtual control object (virtual hand) to cut around the virtual object to be cut (stick); the other is translational cutting, namely (a virtual cutting tool) is driven by a virtual control object (a virtual hand) to cut on the surface of a virtual object to be cut (a stick) in a translational mode. The specific cutting mode of the virtual cutting tool needs to be determined according to the virtual behavior data.
The method comprises the steps that a terminal firstly judges which cutting mode is specifically adopted when a virtual object to be cut (a wood stick) is cut according to virtual behavior data, and when the virtual behavior data correspond to surrounding cutting, the terminal calculates virtual surrounding cutting data according to a virtual control object (a virtual hand), a virtual cutting tool (an art knife) and the virtual object to be cut (the wood stick); and when the virtual behavior data corresponds to translation cutting, the terminal calculates virtual translation cutting data according to a virtual control object (virtual hand), a virtual cutting tool (utility knife) and a virtual object to be cut (wooden 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.
And 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 cutting according to the-30 ° virtual surround cut data. Here, "-" in front of 30 ° is used to indicate a rotation direction in the circling cutting, and in this embodiment, "+" or no mark indicates clockwise circling cutting around the virtual object to be cut (stick) and "-" indicates counterclockwise circling cutting around the virtual object to be cut (stick). In other embodiments, "+" and no indication may indicate a counterclockwise wrap-around cut and "-" may indicate a clockwise wrap-around cut, which is not particularly 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. In this embodiment, when there is no symbol or the symbol is "+" in front of the cutting value, the cutting is performed in the direction of the tool holder of the utility knife, and when the symbol in front of the cutting value is "-", the cutting is performed in the opposite direction of the tool holder of the utility knife.

Specifically, when the virtual behavior data corresponds to the surrounding cutting, the terminal firstly creates a first 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 creates a first virtual tool component on the virtual cutting tool; secondly, the terminal reads the coordinates of the virtual control object and the coordinates of the first virtual tool component from the virtual behavior data in real time to obtain the coordinates of the first virtual object and the coordinates of the first virtual component; then the terminal takes the first virtual control object coordinate as an original point through the UE4, makes a perpendicular line in the straight line direction of the normal vector to obtain a first surrounding cutting intersection point, and reads the first surrounding cutting intersection point to obtain a first surrounding cutting intersection point vector; the terminal takes the first virtual component coordinate as an original point through the UE4, makes a perpendicular line in the direction of the straight line where the normal vector is located, obtains a second surrounding cutting intersection point, and reads the second surrounding cutting intersection point vector; the terminal calculates the 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 performs cross multiplication calculation on the first surrounding cutting intersection point vector and the normal vector direction to obtain a first included angle identifier for indicating the rotation direction of the first virtual tool assembly; and finally, the terminal determines virtual surrounding cutting data by combining the first surrounding cutting included angle value and the first included angle identification.
The method comprises the steps that a terminal firstly creates a first virtual arrow component on a virtual object to be cut (a stick), wherein the direction pointed by the 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 coordinate of a virtual control object (a virtual hand), namely the coordinate of the first virtual object, is read from virtual behavior data in real time; the terminal also creates a first virtual tool component (empty component) on a virtual cutting tool (art knife) and reads the coordinates of the component in real time to obtain the coordinates of the first virtual component; determining an intersection point, namely a first surrounding cutting intersection point, after a perpendicular line is made to a straight line of a normal vector direction by using the coordinate of the first virtual object as an origin by using a FindClosestPointLine function in the UE4, and then reading to obtain a vector of the first surrounding cutting intersection point, namely a first surrounding cutting intersection point vector; meanwhile, the terminal determines an intersection point which takes the coordinate of the first virtual assembly as an original point and makes a perpendicular line towards the straight line of the normal vector direction, namely a second surrounding cutting intersection point, and reads to obtain a vector of the second surrounding cutting intersection point, namely a second surrounding cutting intersection point vector; 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 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 determines virtual surrounding cutting data by combining the first included angle identifier and the first surrounding cutting included angle value. For example, the calculated first wrap-around cutting included angle value is 30 ° and the calculated first included angle is denoted "-", and the terminal obtains the virtual wrap-around cutting data as-30 °.
When the virtual behavior data corresponds to the translation cutting, the method specifically comprises the following steps:
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 the coordinates of the second virtual object and the coordinates of the second virtual component; the terminal takes the second virtual component coordinate as an origin through the illusion engine, makes a perpendicular line to a straight line where the normal vector direction is located to obtain a first translation cutting intersection point, and reads the coordinates of the first translation cutting intersection point; the terminal also takes the second virtual object coordinate as an origin through the illusion engine, makes a perpendicular line to the straight line in the normal vector direction to obtain a second translation cutting intersection point, and reads the coordinates of the second translation cutting intersection point; calculating to obtain a translational cutting displacement vector by combining the first translational cutting intersection point coordinate and the second translational cutting intersection point coordinate, and calculating the displacement vector by a preset length function to obtain the displacement length; and performing point multiplication calculation on the directions of the translation cutting displacement vector and the normal vector to obtain a displacement identifier, and finally determining virtual translation cutting data by combining the displacement identifier 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 (a stick), the arrow of the second virtual arrow component is in the positive direction, the positive direction of the first virtual arrow component points to the normal vector direction of a cutting surface, and simultaneously reads the coordinates of a virtual control object (a virtual hand) and the second virtual tool component from virtual behavior data in real time, namely the coordinates of the second virtual object and the coordinates of the second virtual component; the terminal takes the second virtual component coordinate as an origin point to make a perpendicular line to a straight line in the normal vector direction through the UE4 engine, determines a first translation cutting intersection point and reads to obtain a first translation cutting intersection point coordinate, and the terminal also takes the second virtual object coordinate as an origin point through the UE4 engine, makes a perpendicular line to a straight line in the normal vector direction, determines a second translation cutting intersection point and reads to obtain a second translation cutting intersection point coordinate; calculating a displacement vector of the first translation cutting intersection point coordinate and the second translation cutting intersection point coordinate through a UE4 engine to obtain a translation cutting displacement vector, and calculating the translation cutting displacement vector through a VectorLength function in the UE engine to obtain the length of the displacement vector, namely the displacement length; and the terminal performs point multiplication calculation on the translation cutting displacement vector and the normal vector direction to obtain a displacement identifier, and finally determines virtual translation cutting data by combining the translation cutting displacement vector and the displacement identifier. The displacement flag may be represented by "+" or "-", for example, the calculated displacement length is 5cm, the calculated displacement flag is "+", and the terminal obtains the virtual translation cutting data +5cm or 5 cm.
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;
and the terminal cuts 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 a virtual translation cutting tool.
For example, in one embodiment, assuming that the virtual surround cut data is-30 °, the terminal performs surround cutting according to the-30 ° virtual surround cut data. Here, "-" in front of 30 ° is used to indicate a rotation direction in the circling cutting, and in this embodiment, "+" or no mark indicates clockwise circling cutting around the virtual object to be cut (stick) and "-" indicates counterclockwise circling cutting around the virtual object to be cut (stick). In other embodiments, "+" and no sign may indicate a counterclockwise wrap-around cut, and "-" may indicate a clockwise wrap-around cut, or signs "1" and "0" are used to distinguish the direction of the wrap-around cut, which is not particularly 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. In this embodiment, when there is no symbol or the symbol is "+" in front of the cutting value, the cutting is performed in the direction of the tool holder of the utility knife, and when the symbol in front of the cutting value is "-", the cutting is performed in the opposite direction of the tool holder of the utility knife. In other embodiments, the "+" and no symbol may indicate cutting in opposite directions of the utility knife handle, and the "-" may indicate cutting in directions of the utility knife handle, or the "1" and "0" labels may be used to distinguish the cutting directions of the translation cutting, which is not particularly limited.
It should be noted that, when the cutting is performed in the translation manner, a cutting range is preset, so that a portion of the virtual cutting tool (utility knife) that is beyond the cutting range is suspended, and a portion that is within the cutting range is in contact with the virtual object to be cut (stick).
205. Calculating a target included angle termination value according to the virtual object to be cut, and judging whether the surrounding cutting of the virtual object to be cut is terminated 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 the 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 the virtual object to be cut (the wooden stick), and reads the coordinate of the third virtual tool component to obtain the coordinate of the third virtual component; secondly, the terminal takes the coordinate of the third virtual assembly as an original point through a UE4 engine, makes a perpendicular line to a straight line in the direction of the normal vector 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 by the normal vector to obtain a second included angle identifier; the terminal determines an initial included angle termination value by combining the second included angle identifier and the second included angle value; and finally, calculating the termination value of the initial included angle by adopting an inverse cosine function to obtain the termination value of the target included angle.
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 angle end value of-60, the target angle end value is 0.5.

If the termination threshold is 0.99 and the calculated target included angle termination value is 1, it indicates that the virtual cutting tool (utility knife) completes the surrounding cutting, and at this time, the virtual object to be cut is terminated to perform the surrounding cutting, and if the calculated target termination value is 0.5, it indicates that the virtual cutting tool (utility knife) does not complete the surrounding cutting, and the terminal needs to continue to calculate the virtual surrounding cutting data and perform the surrounding cutting on the virtual object to be cut (stick).
In 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.
