Embodiment
It is right with reference to embodiment and attached drawing for the object, technical solutions and advantages of the present invention are more clearly understood
The present invention is described in further details.Here, the exemplary embodiment and its explanation of the present invention are used to explain the present invention, but simultaneously
It is not as a limitation of the invention.
In order to the apparent understanding of the present invention, first several nouns of appearance are explained below as follows：
1) operation to be rendered：One camera lens, or one section of scene when rendering, it is necessary to submit into an operation, i.e., do not have also
There is the scene for carrying out rendering operation；
2) frame：One operation to be rendered will often be divided into multiple frames, and each frame is exactly a pictures；
3) frame to be rendered：One frame of operation to be rendered；
4) frame is rendered：Operation to be rendered render an obtained frame for rendering operation after processing；
5) frame losing：Noun is rendered, refers to the state for rendering frame loss.
In view of the frame losing phenomenon occurred in render process, inventors herein propose pre-established by detection it is multiple
Whether the method that renders frame is stored with file, to determine whether there are frame losing.Specifically, in the present embodiment, it is proposed that
A kind of frame losing detection method, as shown in Figure 1, may comprise steps of：
Step 101：Detect whether to be all stored with the multiple files pre-established and render frame, wherein, it is described to build in advance
It is corresponding that each file in vertical multiple files all renders frame with one；
Render and refer in computer graphics, model is generated to the process of image with software.Model strict difinition
The description that language or data structure carry out three-dimensional body, it includes geometry, viewpoint, texture and illumination information.Rendering is
Last procedure of computer animation, and the final stage for making image meet 3D scenes.Various software can be applied to carry out
Image renders, such as：The rendering engine that each animation software is carried, the also software such as RenderMan.Architectural design,
During cartoon making, after the good models of software development such as 3DS MAX, MAYA and animation frame being utilized, by design
Hold and utilize software in itself or aid in software (such as：Lightscape, vray etc.) it is fabricated to final effect figure or animation.
Wherein it is possible to multiple files of above-mentioned preservation image rendering result are established in the following way：
S1-1-1：Obtain operation to be rendered；
Wherein, operation to be rendered refers to the picture not rendered also.
S1-1-2：The file number for determining to establish according to the quantity of frame to be rendered in operation to be rendered；
Operation to be rendered is made of multiple frames to be rendered, can be according to the number for the frame to be rendered for forming operation to be rendered
Measure to determine the file number established.If operation to be rendered is made of 500 frames to be rendered, then, the file of foundation
Number is also 500.
S1-1-3：According to the job parameter and frame parameter of each frame to be rendered in the operation to be rendered, each wash with watercolours is generated
Contaminate the folder name corresponding to frame.
Each wash with watercolours can be generated according to the objective parameter such as each job parameter for rendering frame and frame parameter in operation to be rendered
Contaminate the folder name corresponding to frame.When rendering frame there are during layer parameter, corresponding file also can there are Ziwen accordingly
Part presss from both sides, correspondingly, can be generated every according to the objective parameter such as each job parameter for rendering frame and frame parameter in operation to be rendered
A sub-folder title rendered corresponding to frame.
For example, when operation to be rendered is made of 500 frames to be rendered, can be to be rendered according to this 500 respectively
The job parameter and frame parameter of frame, sequentially generate 500 files to store the frame to be rendered after rendering, that is, render frame.It is worth
It is noted that due to frame losing phenomenon that may be present, thus the number for rendering frame is less than or equal to 500.By detecting 500
The storage condition that frame is rendered in file determines whether frame losing.
In the present embodiment, the file that first can each pre-establish matches one and renders frame respectively, passes through detection
Whether it is stored with the multiple files pre-established in each file and renders frame accordingly, is determined whether to exist and lose
Frame.Frame is rendered i.e., it is possible to detect by way of file scan and whether be stored with multiple files, determines whether exist
Frame losing.
Further, when carrying out frame losing detection, can basis establish the identical method of multiple files with above-mentioned and determine
Title for the file for carrying out frame losing detection.I.e., it is possible to according to each job parameter for rendering frame in operation to be rendered and
The folder name that frame parameter is generated, to obtained with the multiple of corresponding document folder title according to S1-1-1 to S1-1-3
File is scanned, and frame is rendered to determine whether to be all stored with obtained multiple files.Exist when in frame to be rendered
During layer parameter, at this time, if according to the file that each job parameter for rendering frame and frame parameter are generated in operation to be rendered
In there are sub-folder, likewise, can scan whether be stored with sub-folder render frame by way of determine whether to lose
Frame.For example, there is the operation to be rendered of 3 frames, first according to the job parameter and frame of each frame to be rendered in operation to be rendered
Parameter establishes 3 files, and folder name is respectively wash with watercolours 1, wash with watercolours 2 and wash with watercolours 3, after the operation to be rendered of this 3 frame is rendered
Result arranged by frame after be sequentially placed into wash with watercolours 1, wash with watercolours 2 and wash with watercolours 3, during using file scan method, according to each in operation to be rendered
The folder name that the job parameter and frame parameter of frame to be rendered are available for frame losing detection is respectively wash with watercolours 1, wash with watercolours 2 and wash with watercolours 3,
Detection and wash with watercolours 1, wash with watercolours 2 and wash with watercolours 3 is corresponding rendered after 3 files in the presence or absence of rendering frame.
In one embodiment, can carry out rendering the identification whether frame is lost by cloud computing technology, wherein, cloud meter
Calculation technology is referred to is split into numerous less subprogram automatically by network by huge calculating processing routine, then transfers to
The bulky systems that multi-section server is formed, user is returned to after the calculating analysis by the system by handling result.Pass through
Cloud computing technology, Internet Service Provider can handle number even hundred million information counted in terms of necessarily within the several seconds, so as to
Improve calculating speed.The analytic process of pictorial information has been come by each calculate node, i.e., each computer for performing render process
Into and collect.For example, if the number of current frame to be rendered is 500, in order to improve recognition speed, 500 can be passed through
Calculate node completes the analytic process of picture, i.e. each calculate node is completed to a detection for rendering frame, so as to realize
The real-time detection of operation frame loss condition to be rendered, i.e. render a frame and just detect a frame, most testing result is collected at last, greatly
The big program time shortened when the detection of frame losing result is carried out using single server.
In the present embodiment, frame is being rendered for the file matching one each pre-established, is then detecting and pre-establish
Multiple files in whether be all stored with before rendering frame, can first pass through parameter positioning mode carry out frame losing detection.Specifically
, it may comprise steps of：
S1-2-1：Rendering operations are carried out to each frame to be rendered in operation to be rendered, obtain multiple rendering frame；
When operation to be rendered is made of 500 frames to be rendered, after being rendered to this 500 frames to be rendered, obtain
Frame number renders frame less than or equal to 500, these are rendered frame preserves into identical file.Wherein, these render frame
Name is determined according to subjective parameters such as the scenario parameters of 500 frames to be rendered.
S1-2-2：According to multiple names for rendering frame, determine that multiple render whether there is frame losing in frame；
Determine to render frame for carry out frame losing detection according to the method identical with determining to render frame name in S1-2-1
Name.When carrying out frame losing detection with parameter positioning mode, can carry out frame losing detection according to being used for of determining renders frame
Name, the frame that renders in file is scanned, determine in S1-2-1 it is multiple render frame whether there is frame losing situations.
S1-2-3：If it is determined that there are frame losing, then multiple frames that render are stored into the multiple files pre-established.
When detecting frame losing using parameter positioning mode, if scenario parameters when subjective parameters are inaccurate, by subjective parameters
The definite frame name that renders also can be relatively fuzzyyer, may result in and renders frame and there is a situation where but to can't detect generation.For example, work as
When the name for rendering frame that the file to be rendered of 3 frames obtains after rendering is frame 1 and frame 3, during using parameter positioning mode, due to parameter
Incomplete, what can be produced renders the situation that frame name is frame 1, frame 2 and frame 4, at this time, because the frame for frame losing detection is entitled
Frame 4, and the entitled frame 3 of frame after rendering, can cause to be mistakenly considered except frame 2, and the situation that frame 4 is also lost occurs.Therefore, it is possible in profit
After detecting frame losing with parameter positioning mode, the multiple frames that render for again rendering operation to be rendered are stored to multiple files
In, determine whether there is frame losing using the method for file scan.
Step 102：Frame is rendered if having detected and not stored in one or more files, it is determined that there are frame losing；
When determining, there are after frame losing, can to determine to lose according to the title for not storing the file for rendering frame detected
That loses renders frame；Meanwhile the configured information for rendering frame that will be lost for instruction, carry in warning message and journal file progress
Output.
Step 103：Frame is rendered if detecting and being all stored with all files, it is determined that there is no frame losing.
When detecting the situation there is no frame losing, video volume can be carried out to multiple frames that render according to default order
Volume, so as to form animation.Wherein, default order can be that frame to be rendered puts in order in operation to be rendered.
Above-mentioned frame losing detection method is illustrated with reference to a specific embodiment, it is important to note, however, that to tool
Body embodiment does not form inappropriate limitation of the present invention merely to the present invention is better described.
In this example, frame losing detection is carried out by the way of file scan.When detecting frame losing, will can be used to indicate
The configured information for rendering frame lost, carries and is exported in warning message and journal file.Specifically, as shown in Fig. 2, can be with
Comprise the following steps：
Step 201：Operation frame catalogue is created in local disk；
Step 202：Rendering result is preserved to the operation frame catalogue of local disk；
Step 203：Detection operation frame file whether there is；
Step 204：If detect that operation frame exists, not frame losing, if it does not exist, then frame losing；
Step 205：If obtaining normal outcome, copied to from local disk by result in shared storage, and set work
Industry is completion status；If frame losing, is set as failure.
In upper example, frame losing detection is carried out by way of file scan, the inspection of frame file can be rendered to avoid large-scale
Survey；Meanwhile determine the name of operation frame catalogue according to each job parameter for rendering frame and frame parameter is rendered in operation, can be with
The frame losing caused by parameter fuzzy is avoided to detect correctness.It can effectively identify whether to lose by way of file scan
Frame.
