Embodiment
Below, with reference to description of drawings example of the present invention.
At first, illustrate and carrying out becoming basic notion aspect the explanation of the present invention.
The storage of user capture constitute the data of virtual reality space database design be the virtual two dimensional surface space or the image display type database of three-dimensional space.Text, rest image, live image, voice, the various objects such as button of various operation usefulness are configured in the optional position of this virtual reality space, and this allocation position defines with two dimension or three-dimensional coordinate.The user plants oneself in this virtual reality space, can move in this virtual reality space, and by moving, the user can be from CRT, and display device such as LCD obtain to be accompanied by the image information that moves continuous variation.
Fig. 1 and Fig. 2 illustrate the example of the virtual reality space of each two-dimentional virtual reality space and three-dimensional.
In virtual reality space, the residing position of user is called " customer location "." customer location " in the two-dimensional virtual realistic space, (x y) records and narrates, in the three-dimension virtual reality space, (x, y z) record and narrate with three-dimensional coordinate with two-dimensional coordinate.Equally, the position that is arranged on the object in the virtual reality space is also used two-dimensional coordinate (x y) is recorded and narrated, and (x, y z) record and narrate also to use three-dimensional coordinate in the three-dimension virtual reality space in the two-dimensional virtual realistic space.
If as original state, the user is positioned at " customer location " arbitrarily of user or server one side appointment.This position is as " customer location under the original state ".
Above-mentioned " customer location " expressed to the user as described below.That is, in the two dimensional surface space, perhaps on picture, show mouse pointer, perhaps customer location is presented at the viewing area central authorities of display device, express " customer location " to the user thus.In addition, in three dimensions, perhaps on display device, show the image that " customer location " in the virtual reality space watched, perhaps in virtual reality space, show mouse pointer or character moulding, express " customer location " to the user thus.
Under original state, in client's's (refer to the signal conditioning package that the user uses, below identical) memory storage, do not read in the overall data of virtual reality space, and only read in peripheral a part of data of customer location.As this part of reading in, be to be the data that the center has the virtual reality space of preset range with " customer location of original state ".Preset range becomes the scope of which kind of degree, according to the total amount of client's memory storage, physical property limit decision such as the display capabilities of display.
Fig. 3 and Fig. 4 are the concept maps of the state that reads in of the data under the original state that illustrates in the virtual reality space, and Fig. 3 illustrates the situation of two-dimensional virtual realistic space, and Fig. 4 illustrates the situation in three-dimension virtual reality space.
According to " customer location " P in user's the indication mobile virtual realistic space and show, the user feel just as own in virtual reality space, move.In this case, the user uses mouse, keyboard, and various input medias such as control lever, indication customer location P moves.For example, the rolling mouse pointer is specified moving direction with cross key or control lever, and the volume bar of going up of picture is moved, and picture is rolled up etc. generally, carries out the mobile indication from the user.
If the user moves up to satisfying certain condition along direction arbitrarily, then the client provides the indication that reads in the spatial data of setting at user's moving target place for having stored the server that constitutes the data of virtual reality space.
In the present invention, virtual reality space constitutes by having disposed a plurality of units virtual reality space with adjoining each other.Here, so-called " unit virtual reality space " refers to the zone of the employed minimum unit of reading in when user's display virtual real space.
In the data of the virtual reality space of having read in, putting down in writing the data of the continuous unit virtual reality space that is positioned at its peripheral all directions.As an example, consider two-dimensional virtual realistic space with a plurality of foursquare units virtual reality space formation.
Fig. 5 is the concept map of the two-dimensional virtual realistic space when constituting with a plurality of foursquare units virtual reality space.Among Fig. 5, the foursquare virtual reality space U1 of unit corresponding to customer location under the original state is read among the client.Here, the unit virtual reality space that comprises customer location is called " base's virtual reality space ".In the title of the data of the virtual reality space U1 of unit, putting down in writing filename with all unit virtual reality space of this unit virtual reality space adjacency.In example shown in Figure 5, putting down in writing up and down oblique upper, the filename of 9 unit virtual reality space that 9 directions such as oblique below are continuous at the virtual reality space U1 of its unit.Here, the unit virtual reality space of establishing with certain unit virtual reality space adjacency is called " in abutting connection with the unit virtual reality space ".In addition, so-called adjacency refers to the relation that can directly not move to another virtual reality space from certain unit virtual reality space via other unit virtual reality space that is in.In addition, among Fig. 5, with 9 of the virtual reality space U1 of unit adjacency in the unit virtual reality space, only show be positioned at the drawing upside in abutting connection with the virtual reality space U2 of unit, other omission.
If carry out user's moving and satisfied predetermined condition in virtual reality space, the filename in abutting connection with the unit virtual reality space that has of client's reference units virtual reality space U1 then reads in the data of the unit virtual reality space that prediction necessitates for server requests.In addition, the continuity of virtual reality space is different with realistic space, owing to be in virtual reality space eventually, therefore between the unit virtual reality space that adjoins each other in virtual reality space, also can remain in the server of diverse position.In addition, according to condition, the unit virtual reality space that adjoins each other also can be different.For example, also can be become other space by the unit virtual reality space that the user has once visited.
At this moment, preferably handle parallel carrying out about the processing of reading in of the data of new unit virtual reality space with other of continuous display process that moves or be called virtual reality space of user in virtual reality space.Thus, during input the reading in of data, can prevent to interrupt user's operation.In the example of Fig. 5, if customer location P near in abutting connection with the virtual reality space U2 of unit, then the client predict need the virtual reality space U2 of the unit of reading in data, send the data of the virtual reality space U2 of unit to server requests.
In addition, read in parallel mutually with the data of new unit virtual reality space, preferably by the moving of user, also discarded or remove the data (with the rightabout data of user's moving direction) in unwanted space, picture demonstration aspect in client's the memory storage.
The position that is accompanied by the user is moved and is carried out above operation repeatedly, and the user will feel that the virtual two-dimensional space or the three dimensions of the huge quantity of information that comprises the storage device capacity that has surpassed the client infinitely enlarge.
[structure example of system]
Fig. 6 is the skeleton diagram of an example that the network system of the device that is used for the display virtual real space comprising of this example is shown.
System by disperse and remain on server 651,652 more than at least 1 ..., the two dimension in the memory storage of 65X or three-dimensional virtual reality space database 661,662 ..., 66X, and constitute through user's one lateral terminal (hereinafter referred to as " client ") 610 that these databases can be visited in network 620, server zone 630 and internet 640.Here, so-called user refers to the people who utilizes virtual reality space.
Client 610 is connected through networks 620 such as servers 630 and LAN, the user is through its server 630, visit through other server 651,652 of being connected with network 640 with server 630 ..., 65X.The server 620 that the user directly visits does not need to keep the data of virtual reality space, needs only the indication that can transmit the client for other server.In addition, the client is not limited to this mode with being connected of server, so long as the connected mode that can intercom mutually then can be any connection.
Client 610 preferably can the parallel processing data read in processing, and corresponding to the processing that move the position or picture shows of user's request.For example, can use the computing machine of the OS (Windows of Microsoft (login trade mark) or UNIX etc.) that has carried the multitask correspondence, as long as use can the walk abreast computing machine of the such processing speed of a plurality of processing of applicator one side with display virtual real space to constitute the client.
(the 1. maintenance of virtual reality space database)
(1.1. unit's virtual reality space)
Above-mentioned virtual reality space database 661,662 ..., the physical property boundary of 66X and overall system matches segmentation design in limited data space.The output of base unit when this data space that has been segmented becomes the client indication is read in to(for) server.The data space of the base unit when indication is read in output for server this client calls " unit virtual reality space ".
In " unit virtual reality space ", accommodate data such as the image that is presented in this data space, text or coordinate that they disposed.
Though in the present invention can be an image or text data etc., the data that combine with its position coordinates are as " unit virtual reality space ", if but consider the efficient that data are read in and the efficient of data base administration etc. then preferably have a certain size can memory image or the file of the data space of text be used as " unit virtual reality space ".
About the shape of " unit virtual reality space ", in the scope that can digitally record and narrate, can use shape arbitrarily.For example, the shape of the unit virtual reality space of using in the two-dimensional virtual realistic space not only can be a square, can also be regular hexagon etc., the shape of the unit virtual reality space of using in the three-dimension virtual reality space not only can be that cube can also be positive tetrahedron or regular octahedron etc.In the following description,, in two-dimensional space, enumerate square, in three dimensions, enumerate cube as the simplest concrete realization example.
Below explanation is in each " unit virtual reality space ", continuous which kind of unit virtual reality space around it.
Virtual reality space is if the two-dimensional virtual realistic space then has the scope in the space of recording and narrating with the xy coordinate, if three-dimensional coordinate then has the scope in the space of recording and narrating with the xyz coordinate.In addition, in this example, the coordinate system as the position of the expression position of virtual reality space or its internal object illustrate the situation of use orthogonal coordinate system, but also can use other coordinate system.
When having considered as " unit virtual reality space " overall huge virtual reality space, the data in each unit virtual reality space do not need to record and narrate with a unified coordinate axis group (absolute coordinates).For example, be that example describes with the virtual reality space that constitutes with cubical unit virtual reality space below.
Fig. 7 illustrates the part of the virtual reality space that constitutes with cubical unit virtual reality space.
In the figure, the virtual reality space C1 of unit of cube shaped with (10 * 10 * 10) size be defined as its cubical angle O1 be positioned at initial point O (x=0, y=0, z=0).Definition is adjacent and have an onesize virtual reality space C2 of unit with the upside in its cube metadata space.Upside at the virtual reality space C2 of this unit further defines the virtual reality space C3 of another cube unit.
At this moment, the 2nd the virtual reality space C2 of unit is configured to its cubical angle O2 and is positioned at x=0, y=10, and the point of z=0, the 3rd the virtual reality space C3 of unit is configured to its cubical angle O3 and is positioned at x=0, y=20, the point of z=0.Each of the virtual reality space C1 of unit, C2, C3 has image or text.
If in order to above-mentioned initial point O (x=0, y=0, z=0) record and narrate the image that the virtual reality space C1 of these units, C2, C3 have or the coordinate position of text object uniformly for the absolute coordinates of benchmark, then, will have the huge coordinate figure that computing machine can not be handled sometimes along with virtual reality space becomes very big.
Therefore, in this example, the coordinate position of objects such as image that each unit virtual reality space has or text is with the coordinate of its each unit virtual reality space (below, be called " unit virtual reality space coordinate ") definition.For example, the object in the virtual reality space C1 of unit is the coordinate representation of initial point in order to the reference point O1 of C1, and the object in the virtual reality space C2 of unit is the coordinate representation of initial point in order to the reference point O2 of C2.
In addition, though narrated the continuity of each unit virtual reality space, do not used absolute coordinates axle or common coordinate axis to define certain unit virtual reality space and be positioned at the so mutual position relation of unit virtual reality space in position apart from other unit virtual reality space top 20.
On the other hand, in case after a plurality of " unit virtual reality space " be read into the client, the local coordinate that is mapped to again in the client was used.
(data in the 1.2. server keep)
Virtual reality space database shown in Figure 6 661,662 ..., 66X each in, with the form that can read according to " unit virtual reality space " unit, keeping being used to constitute the data of virtual reality space.
(flow process of the processing behind the 1.3. client access server)
, illustrate that the client obtains to be used for the data in display virtual real space with virtual reality space unit of unit, and show the processing of these data to Figure 11 below with reference to Fig. 8.Fig. 8 illustrates the client of this example and the process flow diagram of the processing between the server, Fig. 9 is the concept map that is used for illustrating that the data that move of " customer location " that be accompanied by the two-dimensional virtual realistic space are read in, and the data of Figure 10 unit of illustrating virtual reality space are recorded and narrated example.
(data from the client in the 1.3.1. original state are read in)
The client at first be defined in the unit virtual reality space of reading under the original state (Fig. 8, S1).In addition, so-called original state refers to the state that the data that also do not begin to be used to constitute the unit virtual reality space of virtual reality space are read in.Perhaps, also can be in advance determine the unit virtual reality space of under original state, reading in client or server.Client's process network is to the data (S2) of server zone request transmission corresponding to the unit virtual reality space of defined.At this moment, the information of " unit virtual reality space " that this is prescribed (for example, recorded and narrated the filename of the file of unit virtual reality space, perhaps the URL etc. of the position of its file has been write down in expression) sends to server zone through network etc.
Respond this request, server zone (more particularly, be the server that has the data of this unit virtual reality space in the server zone) obtain the data (S3) of this unit virtual reality space from this virtual reality space database, these data are transmitted (S4) to the client.
Then, the client reads the data of this " unit virtual reality space " that is read at first, and the client is read in the data of its periphery continuous " in abutting connection with the unit virtual reality space " for server requests.According to this request, read in a plurality of data spaces from server zone.Obtaining of the data of " in abutting connection with the unit virtual reality space " is not necessary, according to client's physical property conditions such as memory capacity, even only read in " the unit virtual reality space " of defined, do not influence enforcement of the present invention yet.
Can omit the step that this reads in abutting connection with the unit virtual reality space.But, for not felt, the user reading in of data provides level and smooth virtual reality space display process, and be not a unit virtual reality space preferably, but often read in a plurality of virtual reality space in advance.Aspect the client, though need read in corresponding to client's the display capabilities or the data space of memory capacity, but have more than with a data space but with a plurality of units virtual reality space, for example if cubical example then constitutes the data space that this reads in by 27 " unit virtual reality space ", if foursquare example, then use 9 " unit virtual reality space " to constitute the data space that this reads in, thus, can be taken as small size to the data size of each " unit virtual reality space ".If data size is little, then only this a bit just will reduce the load that network transmits.
In addition, fully read a part of unit virtual reality space, along its this direction growth data file, on the other hand, by the discarded unwanted unit of memory storage virtual reality space from the client, do not carry out processing, can alleviate client's burden thus about showing with the image that shows irrelevant unit virtual reality space.
Then, the client is replaced into client's local coordinate to the coordinate of the data space of " the unit virtual reality space " more than 1 of being read in, and the coordinate according to having been replaced carries out the demonstration (S5) of virtual reality space.For example, when having read in a plurality of " unit virtual reality space ", as previously described, record and narrate the position of objects such as the image that is configured in each or text with each unit virtual reality space coordinate.In order in a continuous virtual reality space, to show coordinate position, be replaced into that the coordinate of having been unified shows with the object of each unit virtual reality space coordinate record.
According to above processing, finish the demonstration of the virtual reality space under the original state.
(1.3.2. is accompanied by user's the reading in of " the unit virtual reality space " that move)
After the demonstration of having finished the virtual reality space under the original state, be accompanied by moving of user in the virtual reality space, outside the user breaks away from the data space that is read into before, must read in " the unit virtual reality space " that be positioned at user's moving direction.
But the user is read under the situation of new unit virtual reality space having begun when reaching the end of reading in the data space that finishes, and the user must wait for the data of reading in its unit virtual reality space.
So, detect user's moving direction (S6), judge whether to read in the data (S7) of new unit virtual reality space.When needed, judge which (S8) is the unit virtual reality space that from then on predictive user will enter be, judge, send the data (S9) of necessary unit virtual reality space through network to the server zone request according to this.At this moment, information via network that should " unit virtual reality space " etc. sends to server zone.
Respond this request, server zone (more particularly, be the server that has the data of this unit virtual reality space in the server zone) obtain the data (S10) of this unit virtual reality space from its virtual reality space database, these data are sent (S11) to the client.
Like this, if begin in advance to read in, then do not need to wait for and read in data.
In addition, the judgement of user's moving direction also can be in comprising the unit virtual reality space of customer location, judges which direction of deflection according to the vector of the moving direction of user's indication.
The method of judging can be considered multiple according to client's processing power.And the present invention uses any method to implement, and it is also conceivable that artificial intelligence ground reads the method for user's route earlier.Here, enumerate the method simple and that realize easily of handling as an example.
At first, the moving direction that detects customer location is described, determines the method for the unit virtual reality space data of reading in according to this moving direction.
Fig. 9 is used for illustrating the concept map of determining the method for the unit's of reading in virtual reality space data according to the moving direction of two-dimensional virtual realistic space.
In this example, the client is current, and to read in the unit virtual reality space that finishes only be that the virtual reality space U2-2 of unit, the virtual reality space U2-2 of this unit become within it that portion has base's virtual reality space of customer location P.This base's virtual reality space be U1-1, U1-2, U1-3, U2-1, U2-3, U3-1, U3-2, U3-3 in abutting connection with the unit virtual reality space, these be do not read in as yet in abutting connection with the unit virtual reality space.
In the unit virtual reality space, along which direction move then which reads in abutting connection with the such record of the data of unit virtual reality space if storing customer location P.For example, have customer location P such record of the virtual reality space U1-1 of the unit of reading in when mobile, record and narrate similarly for other 7 directions along the upper left side.
The record example of the virtual reality space U2-2 of Figure 10 unit of illustrating.Record and narrate the relation of the unit virtual reality space that above-mentioned moving direction is arranged and should read at title division, in the body portion record filename that is configured in the object in this unit virtual reality space is arranged, size is with the coordinate figure of unit virtual reality space coordinate representation.Same in the data of other all unit virtual reality space, recording and narrating the relation of above-mentioned moving direction and the unit virtual reality space that should read at title division, recording and narrating the object that is configured in this unit virtual reality space in body portion.
In addition, in this record example, in a data file, recording and narrating title division and body portion in the lump.But, also not necessarily title division and body portion are collected in the file.The efficient of consideration program or the efficient of data storage also can separately be recorded and narrated title division and body portion in two files.In this case, in the file of title division, recording and narrating the title of the file of corresponding body portion.In addition, can also further be divided into a plurality of files to the file of the file of title division and body portion as required records and narrates.In such example, gather a plurality of file groups with mutual corresponding relation, record and narrate a unit Virtual Space.
Then, other example that moves the method for determining the unit virtual reality space data of reading in according to the user is described.
Figure 11 is used to illustrate the concept map of determining the method for the unit virtual reality space data of reading in according to the skew of customer location.In this embodiment, consider to constitute virtual reality space with foursquare " unit virtual reality space ".Be somebody's turn to do " unit virtual reality space " and then be subdivided into 9 square area a to i (each square area being called " piece that customer location is judged usefulness ").In addition, the square area representation unit virtual reality space among the figure, the numeral of putting down in writing in the inside of each square area has following meaning.
" 1 " expression is 9 unit virtual reality space of reading under original state, " 1 " also represents the unit virtual reality space that should read in when customer location is positioned at piece e, the unit virtual reality space that " 2 " expression customer location should read in when being positioned at piece b, the unit virtual reality space that " 3 " expression customer location should read in when being positioned at piece h, the unit virtual reality space that " 4 " expression customer location should read in when being positioned at piece d, the unit virtual reality space that " 5 " expression customer location should read in when being positioned at piece f, the unit virtual reality space that " 6 " expression customer location should read in when being positioned at piece a, the unit virtual reality space that " 7 " expression customer location should read in when being positioned at piece c, the unit virtual reality space that " 8 " expression customer location should read in when being positioned at piece g, the unit virtual reality space that " 9 " expression customer location should read in when being positioned at piece i.
Customer location P one is positioned in these 9 pieces of usefulness " customer locations judge " some.Be positioned at which " piece ", can easily differentiate from the xyz coordinate of customer location.
The indication of reading in of new data will not take place in customer location P during moving in same " customer location is judged the piece of usefulness ".On the other hand, be accompanied by moving of customer location P, in the moment that moves to other " customer location is judged the piece of usefulness " from certain " customer location is judged the piece of usefulness ", the indication of reading in.
In each [piece], determined to be positioned at its [piece " the center time need read in where " unit virtual reality space " of periphery.
Be accompanied by moving of customer location P, from certain piece (below, be called " piece first ") move to other piece (below, be called " piece second ") situation under, " unit virtual reality space " the cube group's of the periphery that the cube group of " the unit virtual reality space " of the periphery that must read in when being positioned at the piece first must be read in when being positioned at piece second difference becomes to be accompanied by and moves " unit virtual reality space " cube that will newly read in.
Figure 12 be illustrated in the example of Figure 11 when customer location from piece e when piece a moves, read in the data of which unit virtual reality space.
(a) illustrates the unit virtual reality space that should read in when customer location is positioned at piece a among the figure,, is illustrated among Figure 11 the unit virtual reality space of putting down in writing " 6 " that is.Should the unit's of reading in virtual reality space when (b) customer location being shown being positioned at piece e, that is, be illustrated among Figure 11 the unit virtual reality space of putting down in writing " 1 ".At this moment customer location is owing to be present among the piece e, so the data of the unit virtual reality space shown in (b) have been read in and finished among the figure.Thereby the unit virtual reality space that need newly read in can be obtained as get rid of the virtual unit space person shown in (b) (the figure (c)) from the virtual unit space shown in (a).
In addition, poor also becoming simultaneously illustrates useless " unit virtual reality space " cube that will discard, and the discarded process of real data is carried out according to following step.
In addition, in fact, if only judge according to this method, then along reciprocal situation of a plurality of boundary line etc. the time, the indication of reading in of data can take place to send continually, handle slow situation.So, whether reliable for the moving direction of judging the user, preferably not to send the indication of reading in of new data in the moment of moving, but observe to a certain extent after the moving of user to certain piece, send the action of the indication of reading in etc.
Turn back to Fig. 8 once more, to the illustrative judgement of Figure 12, the client asks to send the data (S9) of necessary unit virtual reality space for server according to above-mentioned Fig. 9.Respond this request, server zone (more particularly, be the server that has the data of this unit virtual reality space in the server zone) obtain the data (S10) of this unit virtual reality space from its virtual reality space database, these data are sent to client (S11).
The client has sent after the request (S9) of new " unit virtual reality space " transmission for server, turns back to the processing (S12) of the mobile of customer location or picture demonstration once more.Owing to carry out the request of client " unit virtual reality space ", therefore the not processing such as demonstration of the mobile or picture of the customer location of broken clients instantaneously.And then if receive the data of the unit virtual reality space of being asked, then the client reads this data, being included in the local coordinate system (S13) that wherein coordinate data is transformed to the user, launches the data after the displacement in storer.These handle parallel the carrying out of processing such as demonstration (S12) of moving of best and user or picture.Thereby, the device that the client preferably can corresponding multitask.
(definition again of local data's volume coordinate of 1.3.3. user)
The user moves in the local coordinate system of setting in the client.Dispose from unit virtual reality space and inner object thereof that server reads in after being replaced as this local coordinate system as described above.
If the user moves in the virtual reality space then where no matter moves to, the value of this local coordinate all little by little increases.Handle and ad infinitum to continue the coordinate figure that increases for computing machine and be not suitable for.
So the current location with the user is that benchmark defines local coordinate system more termly, local coordinate system so long as have in order to define the necessary abundant size of the data space that is read into simultaneously among the client gets final product.
In the unit virtual reality space is in the cubical example, consider customer location P from certain " unit virtual reality space " to adjacent " unit virtual reality space " spatial movement the moment, define the method for local coordinate again.
(1.3.4. is accompanied by user's useless " the unit virtual reality space " that move discarded)
Superincumbent step S7 is accompanied by moving of user in S13, read in to be considered to " the unit virtual reality space " that the user moves new space in the past, and like this, data little by little store in client's the storer etc. in the client, have hindered client's action.
So, preferably for example, rightabout " unit virtual reality space " data of moving direction (S14) of and customer location discarded from client's memory storage.Discarded timing depends on client's memory capacity, and is preferably keeping data as far as possible.For example, the user changes one's intention, and when changing the path sharp from the direction of certain direction when coming and return, can read in the data of this position once more.
As the example of discarded determination methods, can consider following method.
From the position of user's current time, judge at any time whether the space of certain " unit virtual reality space " is left more than the specific range, according to the data of having left discarded this position of abundant distance.Here so-called fully distance is according to client's physical property restriction (capacity, the display capabilities of image etc.) regulation.
In addition, under situations such as client's memory capacity is few, can also carry out to reversed in order reading in of new spatial data and discarding of the data of wasted space.
As described above, the data of the virtual reality space of launching on client's memory storage are carried out image by image processing apparatus such as figure plug-in cards and are generated processing, and they are presented at CRT, LCD etc. on the display device, offer user (S15) arbitrarily.
Then, along with moving of customer location,, can realize that the continuous of user in the virtual reality space moves by carrying out the processing of above-mentioned S7 repeatedly to S15.
[client's structure example]
Secondly, client shown in Figure 6 610 structure is described.
Figure 13 is client's a functional block diagram.
The client has Virtual Space data storage device 1301.When this memory storage 1301 is stored from the data of the unit virtual reality space of server acceptance, also storing customer position information.
User's motion detection device 1302 obtains customer position information from this memory storage 1301, this information is sent in abutting connection with the unit virtual reality space obtains decision maker 1303.The customer position information of this decision maker 1303 from sending, judge whether produced the some needs that read in abutting connection with the unit virtual reality space, be judged as when needing, carrying out specific in abutting connection with the unit virtual reality space to adjacency unit's virtual reality space information specific device 1304 notices.
This specific device 1304 of having accepted notice is judged the data of which unit virtual reality space of needs according to predetermined method, acquisition be used to obtain to become needs the unit virtual reality space data (for example, stored the root path and the filename of file of the data of this unit virtual reality space, perhaps in network, use under client's the situation, stored the URL of file of the data of this unit virtual reality space).The data that are used to obtain this unit virtual reality space are in the data of unit virtual reality space, owing to for example as the title storage, therefore can obtain by reading this title.
The data unit of the being sent to Virtual Space information acquisition device 1305 that is used to the unit's of obtaining virtual reality space.Unit Virtual Space information acquisition device 1305 reads the data that become the unit of needs virtual reality space according to these data from the memory storage of storing these data, perhaps send the data of this unit virtual reality space, and receive this data to server requests.
When the unit Virtual Space information acquisition device 1305 of having accepted the data of this unit virtual reality space is written to memory storage 1301 to these data, for coordinate data again definition device 1306 indicate, feasible handle is stored in the local coordinate that coordinate data in the data of the virtual reality space in this memory storage 1301 is rewritten as this client, definition device 1306 carries out this coordinate rewriting computing again, according to operation result, be stored in the rewriting of the data of the virtual reality space in the memory storage 1301.
Accepted the unit Virtual Space information acquisition device 1305 of the data of this unit virtual reality space and also notified feasible the moving of customer location that be accompanied by, removed the gibberish in the data that are stored in the virtual reality space in this memory storage 1301 to useless unit Virtual Space erasing of information device 1307.Scavenge unit 1307 is removed the data that become useless unit Virtual Space according to this notice with Virtual Space unit of unit.
Parallel mutually with reading in of the data of these unit virtual reality space, the processing beyond the data that parallel processing apparatus 1308 carries out the unit virtual reality space of the processing of customer location etc. are read in is sent to image processing apparatus 1309 to result.
In addition, image processing apparatus 1309 accepts to have carried out the data of the later virtual reality space of the removing of the displacement of coordinate data and useless unit virtual reality space from memory storage 1301.
If according to this client's structure, the data that need read in from user's moving projection then, and read in these data in advance, can not make the user wait for that data are read in thus during, the level and smooth of user that can carry out in the virtual reality space moved.
