Description

Improving one's methods of a kind of bore hole 3D content production based on Unity3D

Technical field

The present invention relates to bore hole 3D content making technology, specifically, relate to improving one's methods of a kind of bore hole 3D content production based on Unity3D.

Background technology

Bore hole 3D content production needs the resource file such as model, audio usually, and recycling d-making software makes.The making of resource file will utilize more professional 3 d modeling software usually.The 3D modeling software of main flow has 3DMax and Maya etc. on the market at present.D-making software uses Maya usually, also has the three dimentional graph display such as Unity3D, Unreal Engine4.

Summary of the invention

Technical matters to be solved by this invention is: propose improving one's methods of a kind of bore hole 3D content production based on Unity3D, solves the problem that in conventional art, bore hole 3D content production process two-shot object is fuzzy.

The present invention solves the problems of the technologies described above adopted technical scheme: the hither plane distance adjustment of video camera; Add Image post-processing algorithm, write and make close shot transparence.

Improving one's methods of a kind of bore hole 3D content production based on Unity3D, comprising: the document scene such as model, audio utilizing Unity3D model interface to load to make, and generates object; Arrange scene, efficient combination object; Arrange and be multiplely positioned at video camera on same level line, the spacing between adjustment video camera; The hither plane of adjustment video camera, adds Image post-processing algorithm, writes the object transparence gradually that shader makes close shot, finally synthesized by the image of these video cameras.

Further, the method specifically comprises the following steps:

The first step: the document scene such as model, audio utilizing Unity3D model interface to load to make, generates the assembly that various content production needs;

Second step: utilize the various assemblies imported, design bore hole 3D scene, completes setting work;

Utilize the model file of the modelling Software Creates such as 3DMax, Maya, build the master object in scene; Compile script controls the movement of video camera, object etc. in scene; Audio effect file is added in corresponding assembly, simultaneously can play sound effect when scene display.

3rd step: arrange and be multiplely positioned at video camera on same level line, the spacing between adjustment video camera, the distance between multiple video camera is consistent.

The video camera X-coordinate of No. 1 to No. 8 is different as can be seen from Figure 2, and these eight images with the time difference are exactly the data content with parallax that we need.

4th step: the hither plane of adjustment video camera.The display mode arranging video camera is optically focused lamp-based, arranges the hither plane parameter of video camera.Object in hither plane parameter can not be played up.Near, the far plane pattern of video camera as shown in Figure 3.

5th step: by Image post-processing algorithm, realizes the transparence of close shot object by writing shader, arrange distance parameter m and n, and the object between distance video camera m to n can transparence gradually, until do not show.

In order to realize the bore hole 3D picture after only display synthesis, these eight data contents are carried out Data Synthesis, the algorithm of synthesis carries out RGB permutatation according to the input picture of raster pattern bore hole 3D display characteristic to each bore hole 3D display according to grating alignment form, make the synthesis of multiple views 3D rendering consistent with grating alignment, multiple views 3D rendering synthesis mode is obtained according to raster pattern bore hole 3D display characteristic, because the design of different grating is different, the synthesis mode of multiple views 3D rendering is also different.As a rule, if screen periods is p, grating slope degree is θ, 2D display screen sub pixel width is Wp, and the viewpoint number adopted is K, and these four parameters should meet following relation:

wherein, for on round symbol.

6th step: synthesized by the image of these video cameras, bore hole 3D display device shows, and by testing and debugging parameter, the problem of close shot object obfuscation is resolved.

Embodiment

The present invention is intended to propose improving one's methods of a kind of bore hole 3D content production based on Unity3D, technical matters to be solved by this invention is: propose improving one's methods of a kind of bore hole 3D content production based on Unity3D, solves the problem that in conventional art, bore hole 3D content production process two-shot object is fuzzy.Its core concept is: the basis making bore hole 3D content based on Unity3D, in traditional method for making, adds the adjustment of video camera hither plane parameter; Before video camera synthesis bore hole 3D rendering, add Image post-processing algorithm, according to the transparency of the situation adjustment closer object of reality, solve close shot object and show fuzzy problem on bore hole 3D equipment.

Do further to describe to the solution of the present invention below in conjunction with drawings and Examples:

As shown in Figure 1, the improving one's methods of bore hole 3D content production that realize in this example comprises the following steps:

A. resource file imports Unity3D.The person model, object model etc. of scene domestic demand is made of three-dimensional model Software for producing such as 3DMax, MAYA; Make the skeleton cartoon of corresponding model according to demand; Make audio file;

B. import, design and combine various scenario resources, build virtual scene;

C., on the same level line putting video camera, increasing multiplely has parallax video camera, and the image of each video camera of Real-time Collection.

D., the hither plane parameter of each video camera is set, rejects close shot object.

E. post processing of image, makes close shot object transparence.

F. Images uniting, test and adjustment on bore hole 3D display device.

Create plane plane, the carrier that plane plane exports as final image, is passed to plane plane by the image finally synthesized and shows.

Further, in step c, create the Texture identical with number of cameras, object is the image storing each video camera.Concrete grammar: create the Texture identical with number of cameras; Create shader file, import multiple Texture data collected into, write Images uniting algorithm: by camera acquisition each in Texture to image synthesize one in real time can for the image of bore hole 3D equipment display;

Further, in steps d, the hither plane parameter of each video camera is set.By adjusting the numerical value of k, m and n, the effect of the actual bore hole 3D of examination with computer, makes the blooming of closer object eliminate when in order to be effective.

Further, in step e, realize the transparence of close shot object by writing shader.As shown in Figure 3, parameter m and the n of transparent distance is set, makes the object of distance between m and n can present following effect: nearer object is more transparent, until do not show.

Further, in step f, the concrete grammar of Images uniting is as follows: create the carrier that plane exports as final image, final image can show in plane; Create main camera, object is the final bore hole 3D rendering of Real-time Collection plane, creates main camera for being shown in display device, as the interface that final image exports; Position and the parameter of video camera are set, are placed in plane plane dead ahead, export the final image shown in plane plane in real time.Bore hole 3D display device in testing, according to the parameter that the closer object blur effect of reality constantly adjusts, thus reach the method for blur effect reduction.
