As a kind of optional embodiment, below by by the technical solution of the application be applied to game for further pixel
The technical solution of the application.
The rendering type in game engine Unity is the basic step that a word is rendered in Unity engines below：
Step 1, according to the information of word in font file (font), 6 vertex are generated, wherein this 6 vertex constitute 2
Triangle is formed by and is denoted as the first textures, as shown in figure 8,2 words totally 4 triangles and 12 vertex.
Step 2, the setting according to user in character component, generate mesh information, mesh information include apex coordinate,
Vertex color, texture coordinate (being mapped to first area for indicating) etc..
Step 3, it is handled in the geometry stage of rendering pipeline (Geometry Stage) opposite vertexes information, by vertex
In coordinate transform to screen space.
Step 4, in rasterization stage (Rasterizer Stage) by vertex interpolation texture coordinate and vertex color etc., so
Output needs the word rendered pixel-by-pixel afterwards.
In the related art, it is as follows to retouch side effect implementation by UGUI：Side effect of retouching included UGUI is equivalent to and is drawing
On the basis of original character, additionally it is repeated 4 times drafting operation and obtains retouching side effect, retouch the word when word vertex quantity is not retouch
5 times of vertex quantity.As shown in figure 9, for apply UGUI it is included retouch side component, it can be seen that 1 word shares 10 three
Angular and 30 vertex.
Different from technical solution in the related technology, it is as follows to retouch side effect implementation in the step 1 of the application, to render
For one is retouched side word：
Step 11, according to the information of word in font file (font), 6 vertex are generated, wherein this 6 vertex constitute 2
A triangle.
This step can be realized in Unity engines, similar for the game engine of remaining type, in Unity engines
When middle this function of realization, the operating procedure that can be carried out is：Create an empty game object GameObject；For GameObject
Add Text components；The font attribute and content of Text components are changed, i.e. Text components generate pair Unity engines thus at this time
The vertex information answered.
Step 12, the setting according to user in character component generates mesh information, i.e. the first textures, in mesh information
Including apex coordinate, vertex color, texture coordinate etc..
This step can be realized in Unity engines, when realizing this function in Unity engines, the operating procedure that can carry out
Similar with step 11, Unity engines generate the mesh information of word while generating Text component vertex informations,
That is the first textures.
Step 13, mesh information, the areas UV of essential record original character are changed in the setting according to user in retouching side component
Domain (i.e. first area), according to the regions UV for retouching side expanded in size word, the region after expanding is denoted as second area.
UV coordinates, that is, texture coordinate, indicate the texture range of vertex correspondence, this range includes often entire word
Minimum zone, under the premise of not increasing vertex quantity in this programme, UV ranges can be expanded with accommodate retouch side as a result, avoiding
The result for retouching side is cut.
If " word " is UV ranges when not changing Mesh in left figure in Figure 10, as " word " is to repair in right figure in Figure 10
The UV ranges after Mesh are changed, the foundation for changing Mesh is to retouch the size on side, it can be seen that the range of right figure is more than left figure
Range.
In order to more intuitively compare the front and back UV ranges of modification, as shown in figure 11, it is in red block (frame that i.e. " A " is shown)
Original UV ranges before modification, interior yellow frame (frame that i.e. " B " is shown) is modified UV ranges.
UV before modification and the UV after modification are stored in the tangent variables in UI Vertex structures, are used for
Parameter is passed into Shader and makees data source.
Above-mentioned steps can realize in Unity engines, using the interface for the mesh information for changing Text components in Unity,
After generating the mesh of word, it can detect and whether also be inherited on the corresponding GameObject of Text components simultaneously
The component of BaseMeshEffect, if any the ModifyMesh that can then call in BaseMeshEffect components for being written over
Method.
The step of needing to do in the scheme of step 13 be：
1) realize that a component for being inherited from BaseMeshEffect, class name are named as TextModMesh, and by this component
The GameObject being added to where Text components；
2) mesh is changed in the ModifyMesh methods that TextModMesh is rewritten, specific amending method is：It uses
VertextHelper.GetUIVertextStream () method acquisition mesh vertex informations in Unity engines, adjacent 3
A vertex constitutes 1 triangle, takes the directions x (or first direction) and the directions y (or second direction) in this triangle
Maximum value Xmax, Ymax and minimum value Xmin, Ymin are the original regions UV, and user setting retouches on reading TextModMesh
Side size OutlineSize attributes (namely first threshold), Xmax, Ymax are plus OutlineSize up to new newXmax
(i.e. third parameter), newYmax (i.e. the 4th parameter), Xmin, Ymin subtract OutlineSize up to new newXmin (i.e.
Five parameters), newYmin (i.e. the 6th parameter).The value that this step obtains is exactly to be added to the new UV ranges for retouching border region.
Above-mentioned calculating step formula is as follows
Xmax=Math.Max (Vertex1.x, Vertex2.x, Vertex3.x)；
Ymax=Math.Max (Vertex1.y, Vertex2.y, Vertex3.y)；
Xmin=Math.Min (Vertex1.x, Vertex2.x, Vertex3.x)；
Ymin=Math.Min (Vertex1.y, Vertex2.y, Vertex3.y)；
Function Math.Max is used to obtain the maximum value of several parameters in bracket (), and Math.Min is for obtaining bracket
The minimum value of several parameters in (), Vertex1 to Vertex3 indicate three vertex of triangle, Vertex1.x tables respectively
Show the x coordinate of triangular apex 1, remaining meaning such as Vertex2.x is similar.
(Xmin, Ymin) and (Xmax, Ymax) is the original regions UV；
NewXmax=Xmax+OutlineSize；
NewYmax=Ymax+OutlineSize；
NewXmin=Xmin-OutlineSize；
NewYmin=Ymin-OutlineSize；
(newXmin, newYmin) and (newXmax, newYmax) is to be added to the regions UV after retouching border region (i.e. second
Region).
By (Xmin, Ymin) and (Xmax, Ymax), (newXmin, newYmin) and (newXmax, newYmax) passes through
The interface VertexHelper.AddUIVertexTriangleStream () that Unity is provided passes to Shader.
Step 14, it is handled, will be pushed up in the geometry stage of rendering pipeline (Geometry Stage) opposite vertexes information
Point coordinates transforms in screen space.
This step can be based on modifying realizations to TextShader in Unity engines, and first in Shader renders
In the pass of channel, by each apex coordinate of incoming Shader and "current" model view projections matrix multiple to get vertex correspondence
Screen space coordinates.
Calculation formula is：Float4vertexPos=mul (UNITY_MATRIX_MVP, Input.vertex), float4
Indicate that a kind of data type, vertexPos indicate that the screen space coordinates of vertex correspondence, mul indicate to be multiplied, UNITY_
MATRIX_MVP indicates that "current" model view projections matrix, Input.vertex indicate apex coordinate.
Step 15, in rasterization stage (Rasterizer Stage) by vertex interpolation texture coordinate and vertex color etc.,
When exporting pixel-by-pixel, the original texture color in the upper left of current pixel, upper right, lower-left, bottom right, upper and lower, left and right totally 8 directions is sampled
Value, the color value obtained after being averaged merge to obtain final output namely the second textures with the texture color value of current pixel.
