The special video effect synthetic method structure chart of the flow chart form that the embodiment of the present invention provides, as it is shown in figure 1, include:
The organizational structure of flow chart is the tree-like connected graph of a kind of node, uses the mode of tree-like connected graph, allows flow chart
There is suitable motility organizationally
The ultimate unit of flow chart is node, and node includes: input and output connection, view data is from the input of node
Junction point inputs, and through the process of node, exports from output connection.
The link information of each junction point, including the connected node of this junction point, and which connection of connected node
Point etc.；
Each node can record its input, the junction point number of output, call number, title and the company of each junction point
Connect information.
Based on the above embodiment of the present invention, the tree-like connected graph of node can be set up.Use the mode of tree-like connected graph,
User can the most arbitrarily build the flow processing structure of specially good effect.
The ingredient figure of the special video effect synthetic method of the flow chart form that the embodiment of the present invention provides, as in figure 2 it is shown,
Flow chart is made up of input node, special effect processing node and output node three part.
Input node: the input node of flow chart is a timeline sequence, this sequence is just as the input joint of flow chart
Point, input node does not has incoming junction, only one of which output connection.User pulls a material in flow chart, can be from
One timeline sequence of dynamic generation, is inserted into a track, then using this timeline sequence as an input source by this material.
The queue of one timeline sequence of interface record of flow chart, often adds an input source, will add a sequence in queue
Row.And timeline sequence can record the track of this sequence, track then can record material fragment and its relevant information of insertion.
So, when playing flow figure, we just find each sequence from the queue of the timeline sequence of flow chart, then play
These sequences, obtain view data.
Special effect processing node: each stunt is a node, according to the difference of stunt, each stunt node has
One or more inputs, output connection.Interface for each stunt node can record the algorithm of this stunt, works as flow chart
During broadcasting, from each stunt node interface, just find the algorithm of this stunt, thus produce the most different specially good effects.Because each
Stunt couples together according to tree structure, and the input of a stunt is the output of another stunt, the most just completes and regards
The specially good effect synthesis of frequency.Therefore different stunts can be coupled together with different organizational structuries by user according to the design of oneself,
Complete the creation of oneself.
Output node: flow chart has an output node, this node has an input and output connection.This nodes records
On the interface of flow chart, when flow chart exports, find this output node, after its output connection is synthesized
View data.
As it is shown on figure 3, be the operational flowchart of the special video effect synthetic method of embodiment of the present invention flow chart form, its bag
Include adding and deleting and the connection of flow chart node and disconnection of flow chart node.
Flow chart is provided with the mapping table of a node, have recorded all of node.When user adds on interface or deletes
Except a node, we are the most corresponding changes this mapping table, the member of the inside is added or deletes.
The node of flow chart is the interface externally connected with respective input, output connection, can be connected with each other.When with
Two nodes are coupled together on interface by family with a line, just record connection on two respective junction points of node
Information, including connected node, the junction point of connected node, this call number connected etc..One incoming junction can only
It is connected on an output connection, and an output connection may be coupled to a lot of incoming junction.Therefore connection is exported
The link information of point can arrange a mapping table, records its different output and connects.Based on above-described embodiment, a stunt node
Output image by used by one or several node, can so be more beneficial for the specially good effect synthesis of complexity.
When user disconnects a connection on interface, and we just change the connection of these two junction points connected
Information.
As shown in Figure 4, for flow chart subgraph embedding of special video effect synthetic method of embodiment of the present invention flow chart form
Set.
One group of node connected by tree structure is exactly a sub-flow chart, and it can be nested in another as an entirety
In individual flow chart.Being provided with a container node, container node itself does not has special effects, is used only to contain a son
Flow chart.The number of this container node input and output junction point is by the connection number between its internal sub-process figure and extraneous node
Determine.The interface of container node can arrange a mapping table, have recorded all nodes in the sub-process figure that it is internal, and these
In the link information of the junction point that the annexation between node remains recorded in each of which.Container node is an entirety joint
Point, its input and output junction point is the interface that its internal sub-process figure is mutual with the external world.Therefore on the interface of container node
Having two mapping tables, one to have recorded the incoming junction of container node corresponding with which node of sub-process figure, these nodes
It is referred to as the input node of sub-process figure.Another have recorded the output connection which node pair with sub-process figure of container node
Should, these nodes are referred to as the output node of sub-process figure.When a container node connects with other nodes as an integral node
When connecing, as general node, the junction point of container node can record respective link information, and container node by that two
Individual mapping table, connects the link information of this outside with sub-process figure.
Pass through the above embodiment of the present invention, it is possible to achieve the marshalling of node, or some node organizations are become a function
Property module directly use, more can realize the connection of three-dimensional synthesizer.Three-dimensional sub-process figure within synthesizer is scene graph,
There is the light in scene, video camera, each ingredient such as render.It is the hugest that this scene graph can be built, but can
It is directly embedded in flow chart in the way of with three-dimensional this container node of synthesizer, very convenient.
The special effects that container node is possessed is determined by its internal sub-process figure completely.User can enter container joint
Point is internal changes this sub-process figure, including adding deletion of node, and attachment structure of change node etc..Group flow chart occurs
Change, in outside, the function that this container node is possessed the most just there occurs corresponding change.
