Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, a flow chart of a virtual water area generating method according to an embodiment of the invention is shown. It should be noted that the virtual water area generating method according to the embodiment of the present invention is applicable to the virtual water area generating apparatus according to the embodiment of the present invention, and the virtual water area generating apparatus may be configured in a Unity3D editor in a terminal, where the terminal may be a hardware device having various operating systems, such as a mobile phone, a tablet computer, a palmtop computer, and a personal digital assistant.

Further, the present specification provides method steps as described in the examples or flowcharts, but may include more or fewer steps based on routine or non-inventive labor. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution. In actual system or end product execution, sequential execution or parallel execution (e.g., parallel processor or multi-threaded environment) may be possible according to the embodiments or methods shown in the figures. Specifically, as shown in fig. 1, the method includes:

s101, acquiring editing data of the current canvas frame.

In this specification embodiment, the editor of Unity3D may provide an editing tool for editing a virtual water area in a 3D game scene, which may be, but is not limited to, a brush, a dropper, and the like.

When a user creates a virtual water area in a 3D game scene by using an editor (hereinafter, simply referred to as an editor) of Unity3D, the editing tool may be activated by clicking an input tool such as a mouse, and then moved in a canvas of the target scene to perform a virtual water area generating operation. As the editing tool moves within the canvas of the target scene, the editor may retrieve the editing data for the current canvas frame.

It should be noted that, after the editing tool is activated, the user may set parameter information of the editing tool, for example, parameters such as a size of the editing tool, a flow rate of the editing tool, and a resolution of the editing tool may be set. The editing data of the current canvas frame may include parameter information of an editing tool in the current canvas frame and intersection position information of the editing tool and the canvas.

S103, writing the editing data of the current canvas frame into a non-idle buffer space; and editing data of historical canvas frames are stored in the buffer space in the non-idle state.

In this embodiment, as shown in fig. 2, before acquiring the edit data of the current canvas frame, the editor may create at least two buffer spaces in response to a virtual water area generation request initiated by a user, where the states of the buffer spaces include an idle state and a non-idle state. The idle state indicates that the cache space is empty and no data is stored; the non-idle state indicates that the buffer space is not empty and stores data, and specifically, the buffer space in the non-idle state stores editing data of a historical canvas frame, that is, the buffer space in the non-idle state stores editing data of all canvas frames before the current canvas frame.

And S105, generating a dot-matrix diagram according to the editing data of all the canvas frames in the non-idle state cache space.

The bitmap represents the distribution of the water surface vertex mesh, and specifically, as shown in fig. 2, a bitmap may be generated according to edit data of all canvas frames in a non-idle buffer space, and then the bitmap may be generated according to the bitmap.

In a specific embodiment, the editing data of the canvas frames includes parameter information of an editing tool corresponding to each canvas frame and intersection position information of the editing tool and the canvas. The parameter information of the editing tool is preset parameter information of the editing tool in each canvas frame, and may include, for example, parameter information such as the size of the editing tool, the flow rate of the editing tool, and the resolution. The intersection position information of the editing tool and the canvas can be the position coordinates of the intersection in the canvas. Correspondingly, the generating a bitmap according to the edit data of all the canvas frames in the non-idle-state cache space includes: and filling pixels according to the parameter information of the editing tool and the intersection point position information to generate the bitmap.

Specifically, the parameter information and the intersection position information of the editing tool may be transmitted to a shader of a GPU (graphics Processing Unit), the shader of the GPU may perform filling of corresponding pixels according to the parameter information and the intersection position information of the editing tool to generate a bitmap, and then the bitmap may be written into a non-idle cache space. Of course, the parameter information of the editing tool and the intersection position information may also be transmitted to a Central Processing Unit (CPU), and the CPU may generate the bitmap.

In order to achieve precise control of the boundary of the subsequently generated virtual water area to achieve natural engagement with the surrounding scene, in an embodiment of the present specification, the parameter information of the editing tool may include a feather value. Correspondingly, when the bitmap is generated by filling pixels according to the parameter information of the editing tool and the intersection point position information, the eclosion area and the non-eclosion area can be determined according to the eclosion value and the intersection point position information, and then pixel points with different color values are respectively filled into the eclosion area and the non-eclosion area to obtain the bitmap. For example, the feathered region may be filled with gray pixels, and the non-feathered region may be filled with white pixels, as shown in the schematic diagram of the bitmap shown in fig. 3(a) in fig. 3.

In this embodiment, the generating a bitmap according to a bitmap may adopt a method shown in fig. 4, where as shown in fig. 4, the method may include:

s401, determining a feather area and a non-feather area in the bitmap according to color values of pixel points in the bitmap.

For example, a region filled with gray pixels is determined as a feathered region, and a region filled with white pixels is determined as a non-feathered region.

S403, generating a first lattice area corresponding to the eclosion area according to the first lattice density value; generating a second lattice area corresponding to the non-feather area according to the second lattice density value; wherein the first lattice density value is greater than the second lattice density value.

S405, generating a dot matrix map according to the first dot matrix area and the second dot matrix area.

In this way, the feather area of the edge in the generated bitmap has higher density of points, and the density of points in the non-feather area is relatively lower, as shown in the schematic diagram of the bitmap 3(b) in fig. 3, so that it can be ensured that the vertices of the mesh model generated based on the bitmap subsequently contain more required vertex data information, which is beneficial to realizing the effect of natural engagement.

In order to implement processing on consecutive canvas frames, avoid error reporting and improve processing efficiency, in an embodiment of the present specification, a write operation and a read operation for a non-idle state buffer space are separated, as shown in fig. 2, after a bitmap is generated according to edit data of all canvas frames in the non-idle state buffer space, the edit data of all canvas frames in the non-idle state buffer space may be written into the idle state buffer space, and the non-idle state buffer space is changed to the idle state buffer space, that is, after the edit data of all canvas frames in the non-idle state buffer space is copied to the idle state buffer space, the non-idle state buffer space may be emptied to convert the non-idle state buffer space into the idle state buffer space.

And S107, generating a grid model of the virtual water area according to the dot-matrix diagram.

In the embodiments of the present disclosure, the lattice map may be processed by using a preset triangulation algorithm to generate a triangular mesh model of the virtual water area.

The triangulation is defined as: let V be a finite set of points in the two-dimensional real number domain, edge E be a closed line segment composed of points in the set of points as end points, and E be a set of E. Then a triangulation T ═ (V, E) of the set of points V is a plan G which satisfies the condition: (1) edges in the plan view do not contain any points in the set of points, except for the endpoints; (2) there are no intersecting edges; (3) all the faces in the plan view are triangular faces, and the collection of all the triangular faces is the convex hull of the scatter set V.

Specifically, the preset triangulation algorithm may be an algorithm for forming a regular triangular mesh structure, and as shown in fig. 3(c), is a schematic diagram of a triangular mesh model of the virtual water area generated by using the algorithm for forming the regular triangular mesh structure. Of course, the preset triangulation algorithm may also be an algorithm for forming an irregular triangular mesh structure. The algorithm for forming the irregular triangular mesh structure can be a Delaunay (Delaunay) triangulation algorithm, and the distribution of the vertex points in the triangular mesh model obtained by the Delaunay triangulation algorithm is more uniform, so that the elimination of the generated sawtooth at the edge of the virtual water area is facilitated.

Specifically, if an edge E (two end points are a and b) in E is assumed, E satisfies the following condition: if there is a circle passing through two points a and b and there is no other point in the point set V in the circle, e is called Delaunay edge. If a triangulation T of the set of points V contains only Delaunay edges, the triangulation is referred to as a Delaunay triangulation. Algorithms for implementing the Delaunay triangulation may include, but are not limited to, a flanging algorithm, a point-by-point interpolation algorithm, a split-merge algorithm, a Bowyer-Watson algorithm, and the like.

And S109, rendering the grid model of the virtual water area to obtain the virtual water area.

Specifically, Vertex data of each Vertex in the mesh model of the virtual water area may be obtained, a Vertex data set is obtained and transmitted as an input to a Vertex Shader (Vertex Shader), the data is processed in the Vertex Shader, then, output data of the Vertex Shader is assembled into triangles by the graphics processor, the triangles are appropriately clipped to adapt to a user view (viewport), and the clipped triangles are processed by the rasterization unit, so that fragment (Fragments) data is obtained. Fragment data is a simple data format, each fragment data contains all the pixels of a triangle that can be displayed on the screen, and the data content of the fragment data is usually determined by a vertex shader. In fact, the vertex shader may output the vertex attribute parameters as its own output. The rasterization unit is responsible for performing color interpolation (interplate) on vertex data output by the vertex shader on a triangle, so that each pixel on the fragment data obtains a correct attribute value. Thereafter, the interpolated unprocessed fragment data is transmitted to a fragment shader (fragment shader), which determines and outputs the final color of each pixel in the fragment data, thereby completing the rendering.

It should be noted that, in addition to the fragment data received by the fragment shader, some pre-stored texture data may also be passed to the fragment shader for sampling by the fragment shader.

In order to more clearly illustrate the technical solution of the embodiment of the present invention, the method for generating a virtual water area of the present invention is described below by taking an editing tool as a brush and a Render Texture (hereinafter, abbreviated as RT) as an example, and it should be understood that the following example does not limit the present invention.

In the pond scene as shown in fig. 5(a), a virtual water area needs to be brushed out of the pond, and a user can start the function of the brush on the control panel of the water in the editor and can set parameters of the brush at the same time, where the parameters of the brush may include the size and the emergence value of the brush. At the same time, the editor will create two equal size RTs, RT1 and RT2, respectively, in response to the virtual water generation request. In this example, a new virtual water area is created in the pond, so both RT1 and RT2 are idle before starting, and at this time, either RT1 or RT2 may be assumed to be in a non-idle state, e.g., RT1 is designated as a non-idle state, after which it is determined whether each is idle or non-idle based on actual data storage in RT1 and RT 2. If the current modification is performed based on the existing virtual water area, the editor acquires the editing data of the existing virtual water area, writes the editing data of the virtual water area into RT1 or RT2, and the RT with the editing data written therein is in a non-idle state.

After that, the mouse on the screen will become a blue cursor, as shown in 5(b) of fig. 5, and the blue range represents the range of the brush, and of course, the size of the range can be adjusted at any time. By holding down the left button of the mouse without dragging the mouse, a virtual water area can be brushed out in the area where water is desired, as shown in fig. 5 (c). The brushing-out process of the virtual water area is described below by taking the first three frames as an example.

When the first frame is brushed, the editor acquires editing data (parameter information of the brush and intersection point position information of the brush and the canvas) of the first canvas frame, writes the acquired editing data of the first canvas frame into the RT1, transmits the editing data in the RT1 into a shader of the GPU for processing, and obtains a corresponding first bitmap, and the first bitmap is written into the RT 1. The editor generates a first bitmap according to the first bitmap in the RT1, generates a first virtual water area grid model according to the first bitmap, and obtains the current virtual water area by rendering the first virtual water area grid model. Further, the editor writes the edit data in RT1 into RT2 and clears RT1 after generating the first bitmap from the first bitmap in RT 1.

When the second frame is brushed, the editor acquires the editing data of the second canvas frame and writes the acquired editing data of the second canvas frame into the RT2, all the editing data (including the first canvas frame and the second canvas frame) in the RT2 are transmitted into the shader of the GPU for processing, and a corresponding second bitmap is obtained and written into the RT 2. The editor generates a second dot matrix according to a second bitmap in the RT2, generates a second virtual water area grid model according to the second dot matrix, and obtains the current virtual water area by rendering the second virtual water area grid model. Further, the editor writes the edited data in RT2 into RT1 and clears RT2 after generating the second bitmap from the second bitmap in RT 2.

When the third frame is brushed, the editor acquires the editing data of the third canvas frame, writes the acquired editing data of the third canvas frame into the RT1, transmits all the editing data (including the first canvas frame, the second canvas frame and the third canvas frame) in the RT1 into the shader of the GPU for processing, obtains a corresponding third bitmap, and writes the third bitmap into the RT 1. And the editor generates a third bitmap according to a third bitmap in the RT1, generates a third virtual water area grid model according to the third bitmap, and obtains the current virtual water area by rendering the third virtual water area grid model. Further, the editor writes the edit data in RT1 into RT2 and clears RT1 after generating the third bitmap from the third bitmap in RT 1. When the subsequent frame is refreshed, the process is analogized, and the description is omitted here.

To sum up, the embodiment of the present invention obtains the editing data of the current canvas frame, writes the editing data of the current canvas frame into the non-idle cache space, where the editing data of the historical canvas frame is stored, generates a bitmap according to the editing data of all the canvas frames in the non-idle cache space, generates a grid model of the virtual water area according to the bitmap, renders the grid model of the virtual water area, and obtains the virtual water area, so that the model construction of the virtual water area and the generation of the virtual water area can be directly performed in the editor of Unity3D, the step of independently modeling by using a drawing piece in third-party modeling software and then importing a game scene is omitted, the workload of art in the game production process is greatly reduced, and the flexibility and efficiency of game production are improved.

In addition, because the embodiment of the invention directly creates the virtual water area in the Unity3D, the effect of the virtual water area is what you see is what you get, which facilitates the modification of the virtual water area by the creator and improves the creation efficiency. And the structure of the editor of Unity3D does not need to be changed complicatedly, thus being easy to popularize and implement.
