Abstract
The present invention relates to an operation video output and browse method in three-dimensional assembly simulation. The method comprises the following steps: performing order simulation play of the operation three-dimensional animation of the assembly technology; converting the three-dimensional animation as a series of continuous pictures; recording the node information of each assembly operation; and converting each assembly operation picture and the node information to a video file and the corresponding operation information file. The present invention further provides an operation video playing method in a three-dimensional assembly simulation, and the method comprises: obtaining the video file and the corresponding operation information file; selecting an assigned assembly operation and playing the segment corresponding to the video file. The operation video output and browse method in three-dimensional assembly simulation can realize operation break-down browse by using the single video file and the additional index file in the three-dimensional assembly simulation.
Description
Technical field
The present invention relates to Computer-aided Design Technology field, defeated particularly to operation video in a kind of three-dimensional assembly simulation
Go out and browsing method.
Background technology
Machine Design has been realized in three dimensional stress.Machinery production technological design the most gradually realizes three dimensional stress, so three-dimensional work
It is technological trend that skill goes to the workshop.
Three-dimensional assembly system once can show numerous parts, computer graphics system is required the highest.And general work
The workshop of factory does not has high-performance computer.So typically three-dimensional process being recorded as AVI video file, in the terminal of workshop
Play out viewing.Existing mode is that every one procedure records an avi file, but a assembly technology generally comprises tens of road
Operation, it is the most inconvenient that recording dozens of avi file gets up in management.
Summary of the invention
It is an object of the invention to for above-mentioned defect of the prior art.Provide operation in a kind of three-dimensional assembly simulation to regard
Frequency output and browsing method.
The technical scheme is that, operation video frequency output and browsing method in a kind of three-dimensional assembly simulation, including following
Step: the operation three-dimensional animation of assembly technology is play in order emulation；Three-dimensional animation is converted into a series of continuous picture；Record is every
The nodal information of individual assembly process；Each assembly process picture and nodal information are converted into video file and corresponding process information literary composition
Part.
Further, three-dimensional animation is converted into a series of continuous picture and also comprises the steps of and often play one by described step
Frame animation, all carries out off screen for three-dimensional scenic and renders；The time sequencing play according to emulation, by three-dimensional scenic animated transition be
A series of picture.
Further, the nodal information of each assembly process of described step record is further comprising the steps of: whenever from a work
When sequence commences play out or when this operation is switched to next operation, record the title of this operation, operation number and now play frame
Number.
Further, each assembly process picture and nodal information are converted into video file and corresponding process information by described step
File is further comprising the steps of: broadcasting frame number is multiplied by video file target frame rate, obtains the precise time of now video playback；
The time described operation title and this operation are started, terminated is saved in message file one to one；Described picture is turned
Turn to video file；Generate two files: video file, process information file.
Another technical scheme of the present invention is, operation video broadcasting method in a kind of three-dimensional assembly simulation, technical scheme bag
Include following steps: obtain described video file and corresponding process information file；Select to specify assembly process playing video file
Homologous segment.
Further, described step selects to specify assembly process playing video file homologous segment further comprising the steps of:
Read process information file, present all assembly processes；When specifying certain one procedure of broadcasting, find in process information file
Initial time T1 of this operation and end time T2, with T2-T1, obtain simulation time length T3 of this operation；Setting video is broadcast
Put device to commence play out from T1, concurrently set a timer and carry out the timing of time span T3；When timer this operation full
During simulation time length T3, it is automatically stopped video playback.
The invention has the beneficial effects as follows: achieve the single video file of use and an additional index file realizes operation break-down
Browse.
Accompanying drawing explanation
Fig. 1 is operation picture output method schematic flow sheet in a kind of three-dimensional assembly simulation；
Fig. 2 is operation video broadcasting method schematic flow sheet in a kind of three-dimensional assembly simulation.
Detailed description of the invention
The present invention is described further below in conjunction with the accompanying drawings.
S1: open a three-dimensional assembly technique file, emulates according to the process sequence of assembly technology and plays three-dimensional animation.
S2: often play a frame and current three-dimensional scenic is carried out off screen and be rendered into picture, the time play according to emulation is suitable
Sequence, is a series of picture by three-dimensional scenic animated transition.
S3: whenever commencing play out from an operation, and when this operation is switched to next operation, record is now play
Frame number and the title of this operation, operation number.
S4: due to limited and computing power during three-dimensional artificial, direct timing uncertainty is true.Therefore broadcasting frame number is multiplied by AVI
Target frame rate, the just precise time of available now video playback.The operation title recorded before and this operation are started and tie
The time of bundle is saved in message file one to one: the operation title recorded before and this operation are started and terminate time
Between be saved in one to one in the syn file of the same name with avi file；By each pictures according to certain frame per second, use vfw
Technology export compression coding: by each pictures according to the speed of 25 frames per second, use vfw technology export and use H.264
Technology is compressed；Recording can obtain two files after completing, one is AVI video file, and another is syn file.
S6: when playing this AVI, is simultaneously load into AVI video file and corresponding syn file.When avi file is in workshop
When playing out in terminal.Player reads syn file, and demonstrates all process steps in file.Certain is play when user specifies
During one procedure, system finds initial time and the end time of this operation in process information file.With end time-initial
Time, obtain the simulation time length of this operation.Set AVI video player to commence play out from the appointment time of AVI.Set simultaneously
A fixed timer carries out timing.When the simulation time length of timer this operation full, it is automatically stopped video playback.
Those skilled in the art are under the inspiration that the technology of the present invention is conceived, on the basis of without departing from present invention, also
The above-mentioned method for running application program can be made various improvement, this still falls within the scope and spirit of the invention.
