For example, information of any vertex of the first material image may be extracted; for another example, information of all vertices of the first material image may be extracted. Wherein, the vertex information may include the coordinates of the vertex and the like.

As an example of this implementation, if the first material image is not SVG, the coordinates of the upper-left vertex of the first material image may be extracted, and the first material image may be extracted based on the coordinates of the upper-left vertex of the first material image The height and width of the first material image, and the coordinates of the upper left corner of the first material image, the height of the first material image, and the width of the first material image are used as the outline information of the first material image. That is, if the first material image is not SVG, the outline information of the first material image may include the coordinates of the upper left corner of the first material image, the height of the first material image, and the width of the first material image.

As another example of this implementation, if the first material image is not SVG, the coordinates of the upper right vertex of the first material image may be extracted, and based on the coordinates of the upper right vertex of the first material image, the first material The height and width of the image, and the coordinates of the upper right corner vertex of the first material image, the height of the first material image, and the width of the first material image are used as the outline information of the first material image. That is, if the first material image is not SVG, the outline information of the first material image may include the coordinates of the upper right corner of the first material image, the height of the first material image, and the width of the first material image.

As another example of this implementation, if the first material image is not SVG, the coordinates of the lower left vertex of the first material image may be extracted, and based on the coordinates of the lower left vertex of the first material image, the first material The height and width of the image, and the coordinates of the bottom left corner of the first material image, the height of the first material image, and the width of the first material image are used as the outline information of the first material image.

Based on this implementation manner, when the first material image is an SVG, the outline information of the first material image can be extracted quickly and accurately.

As an example of this implementation manner, when the first material image is SVG and the first material image is a concave polygon, the first material image may be divided into at least two convex polygons. Since the collision calculation of concave polygons is much more complicated than that of convex polygons, when the first material image is a concave polygon, the first material image is divided into convex polygons. After a virtual physical entity and/or the first texture entity is added to the virtual scene as a custom material, it can reduce the complexity of the physics engine's collision detection calculation for the custom material, and help improve the physics engine's ability to perform collision detection on the custom material. Accuracy of collision detection. Among them, the physics engine can perform collision detection in each frame of the virtual scene. After the first material image is divided into at least two convex polygons, the contour information of the first material image may include contour information of the at least two convex polygons.

Among them, methods such as vector method (Vector Method) or rotation method (Rotational Method) can be used to divide the concave polygon into at least two convex polygons. For example, in the vector method, for any polygon, the cross product of adjacent edge vectors of the polygon can be calculated to determine whether there is a concave vertex in the polygon. If the polygon has a concave vertex, it can be determined that the polygon is a concave polygon. For any concave polygon, you can select an edge connecting the concave vertices, and calculate the intersection point of the extension line of this edge with other edges of the concave polygon, so as to divide the original concave polygon into two new polygons. Repeat the above steps for each new polygon obtained by segmentation until there are no more concave polygons.

In the case that the first material image is a two-dimensional image, the first virtual physical entity and the first texture entity generated based on the first material image may also be two-dimensional. Certainly, the method of generating a three-dimensional virtual physical entity and/or a three-dimensional textured entity based on a two-dimensional material image may also be preset, so as to generate a three-dimensional virtual physical entity and/or a three-dimensional textured entity based on a two-dimensional material image.

In a possible implementation manner, the generating the first virtual physical entity corresponding to the first material image based on the contour information includes: when the contour information includes a curve segment, converting the curve to The segment is adjusted into a line segment to obtain adjusted contour information; based on the adjusted contour information, a first virtual physical entity corresponding to the first material image is generated. In this implementation manner, when the contour information includes a curve segment, the curve segment may be adjusted to a line segment according to coordinates of two end points of the curve segment. For example, a line segment connecting two end points of the curve segment may be used as a line segment corresponding to the curve segment. The adjusted contour information can be obtained by replacing the curve segment in the contour information with the line segment corresponding to the curve segment. For another example, some connection points (including two end points) can be selected on the curve segment, and two adjacent connection points can be connected to obtain a polyline segment, which can be used as the adjusted contour information. In this implementation manner, when the contour information includes a curve segment, the curve segment is adjusted to a line segment to obtain adjusted contour information, and the first contour information is generated based on the adjusted contour information. The first virtual physical entity corresponding to the material image can reduce the complexity of collision calculation.

As another example, if the material adding code includes first identification information and second identification information, the first virtual physical entity may be obtained according to the first identification information, and the first texture entity may be obtained according to the second identification information. In this example, the target entity includes a target virtual physical entity and a target texture entity, the target virtual physical entity is the first virtual physical entity, and the target texture entity is the first texture entity.

When the target entity only includes the target virtual physical entity, the target virtual physical entity can be used as a custom material; when the target entity includes the target virtual physical entity and the target texture entity, the target virtual physical entity can be used Entity and said target texture entity as the same custom material. In this implementation, the code is added based on the material input by the user to obtain the target entity, and based on the target entity, a custom material is added to the virtual scene, thereby completing the process in the virtual scene through user programming. The addition of materials and the way of adding materials are closely integrated with the programming teaching content, so that the absorption of programming knowledge can be promoted through the process of adding materials.

As an example of this implementation, the target entity includes any of the following: the first virtual physical entity and the first texture entity; the first virtual physical entity; the first virtual physical entity and the first texture entity Two texture entities, wherein the second texture entity is generated based on the second material image; a second virtual physical entity and the first texture entity, wherein the second virtual physical entity is generated based on the third material image. Wherein, the second material image is different from the first material image, and the third material image is different from the first material image. The second material image and the third material image may be the same or different. The second texture entity is different from the first texture entity, and the second virtual physical entity is different from the first virtual physical entity. The above method of generating the first texture entity based on the first material image can be used, and the second texture entity can be generated based on the second material image; the above method of generating the first virtual physical entity based on the first material image can be used, based on the third material image The image generates a second virtual physical entity. According to this example, the first virtual physical entity generated based on the first material image is not bound to the first texture entity, the first virtual physical entity can be used together with the first texture entity, or the first virtual physical entity can be used alone, Or, the first virtual physical entity can be used together with other textured entities other than the first textured entity, or the first textured entity can be used together with other virtual physical entities other than the first virtual physical entity, thereby improving the performance in the virtual scene. Flexibility in working with materials.

In this implementation manner, the target entity only needs to include any virtual physical entity, that is, in other examples of this implementation manner, the target entity may also include neither the first virtual physical entity nor the first texture entity.

As an example of this implementation, the material adding code can call the entity adding interface, and obtain the target entity through the entity adding interface. Wherein, the entity adding interface may represent an interface for adding entities in the virtual scene. The entity adding interface may be encapsulated according to the physics engine and/or the rendering engine. In some application scenarios, the physics engine and the rendering engine can also be combined into one engine, for example, it can be called a physics rendering engine or a physics and rendering engine. In one example, the entity adding interface may be named addCraft.

As an example of this implementation, after the generating the first virtual physical entity corresponding to the first material image and the generating the first texture entity corresponding to the first material image, the method further includes : Adding a custom material in the virtual scene based on the initialization code input by the user and the target entity. In this example, the initialization code can represent the code used to initialize the custom material. According to the initialization code, the initialization state of the custom material in the virtual scene can be determined. In one example, the initialization code can call the entity addition interface to input initialization information. In this example, the entity adding interface can also be used to set the initialization information of the custom material.

In this example, based on the initialization code input by the user and the target entity, a custom material is added to the virtual scene, thereby completing the initialization of the custom material in the virtual scene through user programming, and the custom material The initialization method is closely combined with the programming teaching content, which can promote the absorption of programming knowledge through the initialization process of custom materials.

In an example, the initialization code includes at least one of the following initialization information: initialization size, initialization position, initialization angle, and initialization speed. For example, the initialization code can call the entity adding interface to input the initialization size size=[width, height], the initialization position position=[x ₀ , y ₀ ] and the initialization angle theta. In this example, based on the initialization code input by the user including at least one item of initialization information among initialization size, initialization position, initialization angle, and initialization speed, and the target entity, a custom material is added to the virtual scene , so that the initialization of at least one of the size, position, angle, and speed of the custom material in the virtual scene is completed through user programming. The initialization method of the custom material is closely combined with the programming teaching content, so that the user can The initialization process facilitates the absorption of programming knowledge.

It should be noted that, although the initialization information included in the initialization code is described as above in terms of initialization size, initialization position, initialization angle, and initialization speed, those skilled in the art can understand that the present disclosure should not be limited thereto. The initialization code may include any information used to initialize the custom material. For example, the initialization code may also include initialized visual effect information, etc., which is not limited here.

In an example, the initialization code includes an initialization size; adding a custom material in the virtual scene based on the initialization code input by the user and the target entity includes: responding to the initialization size and the target entity The size of the target entity is different, the size of the target entity is adjusted to the initial size, and then added to the virtual scene. According to the above example, the size of the custom material can be flexibly set.

In one example, the initialization information in the initialization code includes an initialization size and an initialization position; adding a custom material in the virtual scene based on the initialization code input by the user and the target entity includes: When the target entity includes a target virtual physical entity and a target texture entity, based on the initial size, adjust the size of the target virtual physical entity and the target texture entity to obtain a size-transformed target virtual physical entity and size Transformed target texture entity; based on the initialization position, align the size-transformed target virtual physical entity and the size-transformed target texture entity; align the size-transformed target virtual physical entity and The target texture entity after the size transformation is added in the virtual scene.

For example, if the initialization size is size, the initialization position is position=(x ₀ , y ₀ ), and the size of the target entity is size′, then the ratio b=size′/size can be calculated according to the size of the target entity and the initialization size, so that According to the ratio b, the size of the target entity is adjusted to the initialization size to obtain a size-transformed target entity. The set of vertices of the target entity after size transformation can be recorded as A={a ₁ , a ₂ , . . . , a _n }, where n represents the number of vertices of the target entity. The coordinates of the i-th vertex a _i of the target entity can be recorded as ( _xi ,y _i ), where 1≤i≤n. Since the reference coordinate systems of the virtual physical entity and the textured entity are different, in order to paste the target textured entity on the surface of the target virtual physical entity, it is necessary to align the target textured entity with the target virtual physical entity. By traversing the x coordinates of all vertices in the set A, the minimum x coordinate x _min of the target entity can be obtained; by traversing the y coordinates of all vertices in the set A, the minimum y coordinate y _min of the target entity can be obtained. The coordinates of the upper left corner of the target entity can be recorded as (x _min , y _min ). When the target entity includes a target virtual physical entity and a target texture entity, the positions of the target virtual physical entity and the target texture entity may be respectively set as the initialization positions (x ₀ , y ₀ ). According to the initialization position (x ₀ , y ₀ ) and the coordinates of the upper left corner of the target entity (x _min , y _min ), the coordinates (x _p , y _p ) of the center point (pivot point) of the target entity can be calculated, where x _p = x ₀ −x _min , y _p =y ₀ −y _min . The coordinates of the vertex a _i of the target entity can be updated as a′ _i =(xi _−x _min , y _i −y _min ). Therefore, the target virtual physical entity and the target texture entity can be aligned, and the target virtual physical entity and the target texture entity can be initialized with the initial size and initial position. Wherein, in the case that the contour information of any target entity includes contour information of at least two convex polygons, a similar method may be used to calculate each convex polygon separately.

As another example of this implementation, adding a custom material to the virtual scene based on the target entity includes: adding a custom material to the virtual scene based on the target entity and default initialization information. material.

As an example of this implementation, after adding a custom material in the virtual scene, the angle of the target virtual physical entity can be set through the first angle setting interface, and/or, the target texture entity can be set through the second angle setting interface Angle. Wherein, the first angle setting interface and the second angle setting interface may be packaged according to a physics engine and/or a rendering engine. The first angle setting interface can be used to set the angle of the target virtual physical entity, and the second angle setting interface can be used to set the angle of the target texture entity. In an example, the first angle setting interface may be named setAngle, and the second angle setting interface may be named rotation.

In one example, in response to setting the angle of the target virtual physical entity through the first angle setting interface, the second angle setting interface may be called to set the angle of the target texture entity, thereby aligning the target texture entity with the target virtual physical entity. In another example, in response to setting the angle of the target texture entity through the second angle setting interface, the first angle setting interface may be called to set the angle of the target virtual physical entity, so as to align the target virtual physical entity with the target texture entity.

In an example, when the first angle setting interface and the second angle setting interface use different angle units, the angle setting can be performed after unit conversion. For example, in the case where the first angle setting interface uses radians and the second angle setting interface uses angles (degree, also referred to as degrees), in response to setting the radian of the target virtual physical entity through the first angle setting interface, Convert radians to angles, and call the second angle setting interface to set the angle of the target texture entity.

As an example of this implementation manner, after the custom material is added to the virtual scene, the method further includes: setting an interaction mode of the custom material based on the interaction mode code input by the user. Wherein, the interaction method code may represent a code for setting the interaction method of the custom material. The interaction mode set by the user for the custom material may include clicking, dragging, resizing, adding special effects, etc., which are not limited here. For example, a rotation interface and a position interface can be provided to the user, so that the user code can call the rotation interface and the position interface to set the interaction mode of the custom material. Among them, the rotation interface can be used to rotate the custom material in the virtual scene, and the position interface can be used to set the position of the custom material in the virtual scene. The rotation interface and position interface can be packaged according to the physics engine and/or the rendering engine. In one example, the rotation interface can be named rotate and the position interface can be named position. In this example, the interaction mode of the custom material can be flexibly set based on the interaction mode code input by the user, so as to solve the problem that the material in the virtual scene cannot interact or the interaction mode is fixed. In addition, the setting of the interactive mode of the custom material in the virtual scene is completed through user programming, and the setting method of the interactive mode of the custom material is closely integrated with the programming teaching content, so that programming can be promoted through the setting process of the interactive mode of the custom material knowledge absorption.

As an example of this implementation manner, after the custom material is added to the virtual scene, the method further includes: using a physics engine, determining status information of the custom material presented in the virtual scene. In this example, the physics engine may be preset or implemented based on user code, which is not limited here. The physics engine can calculate at least one of motion, rotation, collision, etc. by assigning real physical properties to the custom material. According to this example, the state information of the custom material presented in the virtual scene is determined by the physics engine, so that after adding the custom material in the virtual scene, the physical effect of the custom material can be determined immediately, so that the custom material complies with the physical Principle movement, users do not need to collide with different materials in the virtual scene, and do not need to set action rules, which can improve the convenience of virtual scene setting.
