Fig. 1 is the optimization method flow chart of game picture according to the present invention, below with reference to Fig. 1, to trip of the invention
The optimization method of play picture is described in detail.
Firstly, reducing the memory source that existing object occupies in step 101.Wherein, it records and collects the interior of common object
Deposit data analyzes internal storage data, reduces the unnecessary memory consumption of existing object.In this way, it is possible to reduce the memory of existing object
The demand to memory is greatly reduced in expense, allows the operation of game more smooth.
Preferably, the method for reducing the memory source that existing object occupies includes: to collect internal storage data and be output to disk
On file；It analyzes the disk file and finds out the texture mapping and animation model for needing size reduction；Release with it is described currently it is right
As unrelated memory source.Wherein, using memory consumption analysis tool, internal storage data is collected, saves the interior of service work object
Consumption record is deposited, and is output in disk file.Memory consumption situation is analyzed according to disk file, finds out the big line of memory overhead
Textures and skeleton cartoon model are managed, the precision of texture mapping and the triangular facet number of animation model are reduced.To the code of establishing resource
Investigation analysis, rejecting and the incoherent resource of existing object are carried out, the resource is not created to save memory, is exited in existing object
When, the resource that existing object occupies is discharged in time.It can check that the memory in existing object operation process disappears at runtime in this way
Consumption situation reduces unnecessary memory consumption under the premise of guaranteeing art effect, reduces the demand to memory, improves
The service efficiency of memory.Wherein, memory consumption tool can be UE4, and in UE4, many objects all realize memory consumption
Writing function.These objects include game logic object (UObject), rendering objects (RHI), texture object (Textures),
Static models (StaticMesh), animation model (SkeletalMesh), particle model (ParticleMesh).Every kind of object is also
Have recorded the title and relevant characteristic of resource after it is instantiated, such as the size dimension of texture, the name of texture, model
Name etc..For rendering objects (RHI), UE4 has made specific classification, is divided into post-processing object 3D, post-processing object Cube,
Color device data block, texture mapping 3D, texture mapping 2D, texture mapping Cube, post-processing object 2D, vertex data block, index data
Block.
Preferably, the number of vertex of the animation model is reduced.Wherein, subtract face tool using model, reduce skeleton cartoon mould
The number of vertex of type, in this way, saving vertex memory by reducing vertex number.For example, in UE4 skeleton cartoon model each vertex
The memory of 228 bytes will be occupied, a large amount of vertex memory can be saved by reducing vertex number.Animation model base in game
Each vertex in sheet will occupy the memory of 228 bytes, and the vertex number of many models has reached ten hundreds of ranks, this will
Many GPU vertex memories can be occupied, using the tool for subtracting triangular facet, to reduce model vertices number, each model vertices number
5000 can be reduced to hereinafter, a large amount of vertex memory can be saved by such operation.
Preferably, the image data of the texture mapping secondary layer is read.Wherein, using texture mapping tool to texture maps
Piece specifies suitable grade, and Fig. 2 is the visable representation schematic diagram of 8x8 texture mapping Mipmap, as shown in Fig. 2, the 0th grade is former
The texture mapping size of beginning, the 1st grade subsequently are the half of original size, and so on.In this way, suitably reducing texture mapping
Precision, the demand to memory can be greatly reduced.For example, the size of the 0th grade of texture mapping is 1024x1024, the 1st is selected
Grade is sized at 512x512, and selecting the second level is exactly 256x256.The image data for reading secondary layer at runtime, to often putting up
For figure, the memory close to 3 times can be saved.
Preferably, the huge object big to EMS memory occupation carries out reference analysis.Wherein, it uses the same parent and carries out class
System Design, all subclasses for being derived from it can save an object references array, to record drawing for all related subclasses
With this array can dynamically increase and decrease project, so can theoretically save any number of adduction relationship, object reference is closed
System is saved on disk.The adduction relationship that can thus check some object static state at any time eliminates them need not
The reference in place is wanted, memory overhead when game running is reduced.Such as the object in game level, it is exactly that outpost refers to object
Part has adduction relationship, so that it may the case where resource (being primarily referred to as textures, model) of game is specifically used is known, from money
The angle of source reference, analyzes the service condition of resource, can check out unnecessary resource and use.
In step 102, the existing object post-processing rendering quality is reduced.Wherein, unnecessary post-processing effect is closed,
Reduce post-processing rendering quality.In this way, can solve the problem of image blurring of game picture rendering.
Preferably, reducing the existing object post-processing rendering quality includes: to close the wash with watercolours unrelated with the existing object
Dye configuration.Wherein, it closes going game picture and is not required to correlation engine rendering configurations to be used.In this way, can solve game picture
The problem of image blurring of face rendering.For example, closing unnecessary post-processing effect, setting using the order of UE4
R.DepthOfFieldQuality=0 closes Deep Canvas, the fuzzy effect of setting r.MotionBlurQuality=0 closing movement
Fruit, setting r.LensFlareQuality=0 close Lens Flare effect, r.TranslucentLightingVolume are arranged
Quality=0 closes the light transmission rendering effect of translucent object, and setting r.SeparateTranslucencyQuality=0 is closed
Close the independent rendering pipeline effect of translucent object, setting r.TiledDeferredShadingQuality=0 closes piecemeal
Color rendering effect etc..
In step 103, the existing object rendering configurations are adjusted.Wherein, merge static object batch, shone using static light
Clipping distance coefficient is arranged in textures.In this way, blocking the scene hardware as far as possible in game picture, vegetation design uses geometry
Instance technology reduces the optimization Scenario Design such as material and illumination complexity, so that rendering frame per second is reached 60 frames, improves rendering
Efficiency and rendering performance.
Preferably, merge the existing object static state object batch.Wherein, using layering level of detail system, for working as
The static object of identical rendering material, is combined into a single static object in preceding game picture scene.In this way, it is possible to reduce figure
The draw call of shape reduces the operation expense that CPU calls figure API, improves rendering efficiency.
Preferably, using static light-maps.Wherein, tool is baked using static light-maps, generates scene illumination patch
Figure, generates soft static object shade, can reduce the consumption to performance, improves rendering efficiency.
Preferably, clipping distance coefficient is set.Wherein, the video camera clipping distance system of object in game picture scene is set
Number, adjust scene in object clipping distance, make to be punctured apart from the farther away object of video camera by the cone, be not plotted in cutting away from
From outer object, in this way, improving rendering performance.For example, in 3D computer graphics, view frustums (frustum) refer to field
A visible cone range for video camera in scape, it has upper and lower, left and right, close, remote, and totally 6 faces compositions, intracorporal in the cone
Otherwise scenery is as it can be seen that then invisible.The virtual glasses resolution ratio (1920x1080) of Playstation VR is not very high, distant place
Scene object often seems fuzzy, and the video camera that object can be set cuts coefficient, only has intersection with view frustums in scene
Object drawn, reject the object, such as particle, tree, bone grid etc. outside view frustums.Resolution ratio can be both reduced in this way
It is fuzzy caused by not high, and rendering performance can be improved.
