And distributed system of the invention, more client computer (be equivalent to and introduce multiple host) can be used, by this four Projection device is connected in these client computer, and every client computer is only responsible for the wash with watercolours of the corresponding picture of the projection device being connected thereto Dye, that is to say, that the pressure of the corresponding picture rendering of this four projection devices can be shared in each client computer.If budget is sufficient It is enough, four client computer can be directlyed adopt, every client computer connects a projection device, and this connection type makes every client computer only The rendering pressure for being responsible for a projection device and a traditional host is needed to undertake the rendering pressure of four projection devices It compares, greatly reduces the rendering pressure of client computer, so that the picture rendering of requirements at the higher level can be realized.Certainly, if limited budget, Three client computer can also be used, wherein a client computer connects two projection devices, in addition two client computer are separately connected one Projection device；Or two client computer, every client computer connect two projection devices and all drop compared to traditional system architecture The low rendering pressure of client computer.

As an implementation, a private server (Dedicated Server) can be used to realize and each client computer Network communication connection.

As another embodiment, it is shown if being applied to house ornamentation, a large amount of data is needed unlike game Interaction can not use private server, and the higher mode of cost performance is to use Listen server (Listen Server), Increase corresponding parameter given host starting is the client of server client or client computer.

Such as: use illusory engine 4, specify each host (such as: the terminal devices such as computer, mobile phone, tablet computer) with Listen mode starts client, if being provided that the client of client computer parameter on host, is equivalent to visitor after starting Family machine；If being provided that the client of server parameter on host, a server is equivalent to after starting；If same Not only client computer parameter had been contained in the client being arranged on host but also has included server parameter, after starting this client, both The function of execute server, and execute the function of client computer.

It should be noted that aforementioned described rendering program is to execute in the client for have client computer parameter and rendering phase Close the function program of service logic.

Example is as follows:

If having three projection devices A, B, C and three host As ', B ', C ', photographic equipment A be connected to host A ', photography is set The visitor of client computer parameter is provided that on standby B is connected to host B ', photographic equipment C is connected to host C ', host B ' and host C ' Family end is carried out the service logic that client computer should execute after the two starting, and host A ' on be provided with (existing client computer ginseng Number, have server parameter again) listen parameter client, host A ' perform this client after, be both equivalent to one Platform server, and it is equivalent to a client computer.

In practical application, in order to allow user preferably to watch immersion show surroundings, it is possible to provide human-computer interaction.Such as: User can open the cabinet shown, a certain ornament of replacement etc. by interaction.There are many concrete implementation modes, such as: make visitor Family machine has the function that interact with user, alternatively, allowing the function etc. of server realization human-computer interaction.

Such as: projection screen is two sides, respectively front and the left side, three projection devices is used, wherein first and second Projection device is responsible for positive projection, and third platform projection device is responsible for the projection on the left side, and first and second projection device is connected to One client computer, third platform projection device are connected to second client computer, and the mobile phone of user is as server, with First client Machine and second client computer communication connection.User can allow mobile phone by operational order by hand hands- operation, according to rendering demand Corresponding operating result is synchronized to First client computer and second client computer at the appropriate time.Certainly, if First client computer If also there is interactive function with second client, the hand as server can also be sent to by the client computer of generation operational order Machine, after executing operational order by mobile phone, according to the rendering demand of each client computer, at the appropriate time by the corresponding behaviour of this operational order Another client computer is synchronized to as result.

In the above-described embodiments, the framework of distributed system shares the rendering pressure of each client computer, has both been able to achieve more A screen synch runs the projection of a scene, and can apply to the wash with watercolours of the immersion show surroundings more demanding to image quality Dye, and rendering effect has preferable stability and fluency.The quantity of client computer can also be according to practical need in distributed system Flexible increase and decrease is asked, establishment is convenient, fast, is widely used.

Field is shown based on house ornamentation is applied to, and data are relatively simple compared to for game, can be used Listen Server's Mode sets up distributed system, low in cost, and can flexible setting different terminal equipment be according to demand server, has higher Adaptability.

Based on the improvement of above-mentioned distributed system embodiment, in addition to same as described above, further includes: server 1 is used for Receive the projection device information for connecting each projection device on the clients that each client computer is sent；And receive each institute State the corresponding configuration information of projection device information；And each configuration information is sent to corresponding client computer.

Specifically, between server 1 and client computer 2 information exchange can be carried out after establishing long connection.The two can be used The agreements such as TCP connection, Web-socket agreement in Socket agreement carry out long connection.Once client computer 2 is connect with server 1 The projection device information for each projection device being connected thereto can be pushed to server 1 automatically by success, client computer 2.

Such as: there are two client computer and a server, is connected with a projection device A in First client computer, second Two projection devices B, C are connected in platform client computer, after this two client computer all establish long connection with this server, first The projection device information of projection device A is just sent to server by platform client computer, and second client computer is just projection device B and throwing The projection device information sending server of shadow equipment C, so that the projection device for allowing server to receive this three projection devices is believed Breath.

Projection device information includes but is not limited to: the system of the resolution ratio of projection device, projection device and client computer is shown Mode, the title of projection device, number of projection device etc..

As an implementation, server can pass through default after receiving the projection device information of each projection device Setting obtains the corresponding configuration information of each projection device information.

Specifically, configuration information includes: the projection screen for being responsible for projection.

Such as: server has received two projection device information, and default setting is matching for first projection device information For confidence breath to throw front, the configuration information of second projection device information is to throw the right side.

If a projection screen is responsible for by several projection devices, example is as follows: positive projection screen is set by two projections Standby to be responsible for, the configuration information of first projection device information is to throw positive left side, and second projection device information matches confidence Breath is the positive right side of throwing.

As another embodiment, server 1 is further used for saving and showing each projection device information；Clothes Business device 1, receive the corresponding configuration information of each projection device information and specifically include: server 1 receives user according to display The corresponding configuration information of each projection device information setting.

It is set specifically, server after receiving the projection device information of each client feedback, can be reserved for these projections Standby information, and the projection device information of preservation is fed back into operation user by user interface (User Interface, UI), it uses Family can carry out the setting of configuration information to the corresponding projection device of each projection device information, to make each client computer starting corresponding Rendering program projected picture is rendered.

As shown in figure 4, being two projections of the connection for the client computer transmission that server receives in this client computer The projection device information of equipment, and shown by UI, the corresponding configuration information of first projection device information of user setting To throw front, the corresponding configuration information of the second projection device is to throw the left side.

After each projection device information has its corresponding configuration information, each configuration information can be sent to corresponding client Machine allows it to execute subsequent operation.

Such as: the corresponding configuration information of first projection device information is to throw front, and second projection device information is corresponding Configuration information be to throw the left side, the corresponding projection device of two projection device information is all connected in the same client computer, services The two configuration informations are just sent to this client computer by device, this client computer is allowed to understand the corresponding projection of first projection device information Equipment throws front, and the corresponding projection device of second projection device information throws the left side.

Client computer 2, for when receiving the configuration information that the server is sent, according to the configuration information, Starting rendering program renders corresponding projected picture.

Specifically, the configuration information that each client computer is sent according to server, is arranged corresponding parameter operation rendering program, holds Carry on a shoulder pole the rendering of homolographic projection picture.

Such as: if a client computer has connected two projection devices (respectively No. 1 and No. 2), front and the left side are thrown respectively, that When server by open command (form of open command is not construed as limiting, and can send jointly to client computer with configuration information, Directly configuration information can be mixed in open command) when pass to this client computer, it can be respectively in corresponding projection device A subsidiary data (i.e. configuration information, No. 1 video camera are Front parameter) at ID is positive in No. 1 projector's starting when needing When picture, rendering program can obtain a Front parameter on startup, thus activation before to virtual camera, to just Face picture is rendered；Similarly, the client computer for being responsible for the projection left side can activate the corresponding left side virtually to image by Left parameter Machine.Similarly, at this time if separately having a client computer Lian Liaoyitai projector to need to throw the right side, server is opened notifying it When opening rendering program, the configuration information that he has Right parameter can be transmitted to.

It should be noted that in actual use, after client computer is connected to the configuration information of a projection device, operation peace The client of dress is arranged the corresponding start-up parameter of this configuration information (such as: Front parameter, window coordinates etc.) and calls rendering journey Sequence activates the virtual camera of corresponding position, renders to realize to the picture of this position.Therefore, configuration information is different, although Call the same rendering program, but the start-up parameter being arranged it is different, it can be achieved that different location picture rendering.When a client computer On when having more projection devices, rendering program can be called to render different projected pictures using respective configuration information, It is equivalent to the opening of game client difference account more.

Optionally, client computer 2 start rendering program and render to corresponding projected picture according to the configuration information Include:

Client computer 2 obtains the resolution ratio of the corresponding projection device of the configuration information；And according to the configuration information The system display pattern of corresponding projection device and the client computer obtains window coordinates；And according to the configuration information, The resolution ratio and the window coordinates, starting rendering program render corresponding projected picture.

Acquisition window coordinates are the frame information in order to determine the projected picture of projection device rendering, i.e. a left side for frame information (Left), right (Right), upper (Top), under (Bottom) information, to guarantee the picture position projected after rendering just Really, it does not deviate and size is correct.

Such as: if the resolution ratio of projection device is 2560x1440, it is known that the coordinate of upper left point is (Left=0, Top= 0) coordinate that, then can extrapolate lower-left point is (0,1440), and the coordinate of lower-right most point is (2560,1440), and the coordinate of upper right point is (2560,0).

Therefore, window coordinates directly acquire the coordinate of any one corner points, for convenience of description, in the present embodiment Window coordinates are selected as the coordinate in the upper left corner.

Optionally, when the system display pattern is that (non-expanding mode here is interpreted as non-expanding mode, a client Only it is connected to a projection device on machine, the system display pattern of this projection device and client computer is exactly non-expanding mode) When, the window coordinates are initial coordinate；

When the system display pattern is mode of extension, shows equipment based on the corresponding projection device of the configuration information When, the window coordinates of the corresponding projection device of the configuration information are initial coordinate；

Specifically, window coordinates are initial coordinate, for convenience of calculating, initial coordinate can be set as (0,0).

If being connected with more projection devices in a client computer, these projection devices are connected with mode of extension and client computer It connects, wherein an only projection device is the main display equipment of client computer, other projection devices are all the non-master displays of client computer Equipment, in the operating system of client computer, each non-master display equipment and main display equipment have positional relationship, such as: one is non-master Show that equipment is located at the left side of main display equipment, above or the right side (orientation of software view) etc..The throwing connected with mode of extension The window coordinates of shadow equipment need to be set according to its positional relationship between the projection device as main display equipment and each projection Standby resolution ratio determines.

Such as: two projection devices are connected in same client computer, and (resolution ratio is First projection device Be 1920x1080) mode of extension with the system display pattern of client computer, based on show equipment, configuration information be throw it is positive The system display pattern of right side, second projection device and client are mode of extension, are non-master display equipment, and what it is in client computer is Its in system setting is located at the left side of main display equipment, and configuration information is to throw positive left side, then First projection device is corresponding Window coordinates be (0,0), the corresponding window coordinates adaptability of the second projection device becomes (- 1920,0).

For another example: two projection devices are connected in same client computer, and (resolution ratio is First projection device 1920x1080) with the system display pattern of client computer be mode of extension, configuration information be throw front, based on show equipment, The system display pattern of second projection device and client are mode of extension, and configuration information is to throw the right side, are located at main display The right side of equipment, then the corresponding window coordinates of First projection device are (0,0), and the corresponding window coordinates of the second projection device are suitable Answering property becomes (1920,0).

The window coordinates that each projection device is determined according to system display pattern ensure that the corresponding shadowgraph of each projection device The correct rendering in face enables the harmonious splicing of the picture projected, and user is available more preferable in immersion show surroundings Viewing effect.

Such as: as illustrated in figs. 5-7, by three projection the same face projection screens, their resolution ratio is all 2560x1440 shows based on the corresponding projection device A of Fig. 5 and sets if these three projection devices are all connected in the same client computer Standby, the corresponding projection device C of the corresponding projection device B and Fig. 7 of Fig. 6 is non-master display equipment, the corresponding position projection device B Information is located at the left side of main display equipment in an operating system, and the corresponding location information of projection device B is located in an operating system It is main display equipment the right, the corresponding window coordinates of projection device A be (0,0), the corresponding window coordinates of projection device B be (- 2560,0), the corresponding window coordinates of projection device C are (2560,0).

Certainly, the positional relationship of each projection device may be in operating system: projection device B as main display equipment, Projection device A is located at the right of projection device B, and projection device C is located at the right of projection device A；The corresponding window of projection device B Coordinate be (0,0), the corresponding window coordinates of projection device A be (2560,0), the corresponding window coordinates of projection device C be (5120, 0)。

Optionally, the distributed system of the present embodiment, server 1 are further used for that a client computer hair ought be received When the operational order sent, the operational order is executed, obtains the corresponding operating result of the operational order；And according to rendering Corresponding operation result is sent to corresponding client computer and synchronized by demand；Client computer 2, in render process, when receiving When the synchronous operational order, projected picture is rendered according to synchronous each operational order.

Specifically, operational order can be sent to clothes when producing the operational order of user in any one client computer Business device, by this operational order of server process, after obtaining corresponding operation result, according to the rendering demand of each client computer, suitable When opportunity be sent to other client computer and synchronize, when rendering, each client computer can carry out shadowgraph according to synchronous operating result The rendering in face.Such as: server is the hand-held tablet computer of user, two client computer, client computer A one projection device of connection A ' is responsible for projection front, and client computer B connects another projection device B ', is responsible for the projection left side, when user opens front projection On screen when the door of leftmost side cabinet, this is exactly an operational order, and client computer A generates corresponding operation depending on the user's operation After instruction, sends it to server and corresponding operating result is saved, discovery is worked as after server executes this operational order When the client computer B picture to be rendered is related to this operating result, this operating result is sent to client computer B and is synchronized, client computer B It will appreciate that the door of positive leftmost side cabinet is opened, the projected picture of rendering, also can be its wash with watercolours when being related to this cabinet Dye open appearance.

It should be noted that simultaneously operating result is more substantially to allow the rendering program being responsible for different projected pictures and calling Between synchronization.

Such as: in same client computer, there is two projection devices, wherein the corresponding projected picture of No. 1 projection device be with Configuration information be throw the left side, window coordinates (0,0), the rendering program that oneself resolution ratio be 2560x1440 calling needs it The projected picture on the left side of projection is rendered；The corresponding projected picture of No. 2 projection devices is with configuration information for throwing front, window Mouthful coordinate (2560,0), oneself resolution ratio are the positive projection that the rendering program that 2560x1440 is called needs to project to it Picture is rendered.When a cabinet when the left side is opened, this client computer can be sent to this operational order server, service Device can be corresponding operating result, i.e. the left side a cabinet is that machine is sent in each client computer opening state in due course, wash with watercolours The rendering program for contaminating positive projected picture can also synchronize this operating result, guarantee that the rendering of picture is synchronous.

The acquisition modes of operational order can be implemented by using the prior art, and specific mode is not construed as limiting.Such as: user is in visitor It is input operation instruction on the machine A of family.For another example, pass through the movement of sensor senses user, automatic identification operational order.
