Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present application, the technical scheme in the embodiment of the present application is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only some embodiments of the present application, rather than whole embodiments.It is based on
Embodiment in the application, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of the application protection.
Referring to Fig. 1, the flow of the methods of exhibiting embodiment of the threedimensional model scene provided it illustrates the application.Such as Fig. 1
Shown, the present embodiment can specifically include step S101~step S104.
Step S101：In default painting canvas space, according to user to presetting the moving operation of person model, it is determined that presetting people
The eye position and direction of visual lines of thing model；Wherein, preset in painting canvas space and show default person model.
Wherein, painting canvas space is pre-set, and person model is set in painting canvas space, for simulating currently viewing model
The real person of scene is user.User can pass through the movement of the input device controls person model such as mouse, keyboard, this implementation
Example is according to the shift position of person model, to simulate the different model scenes that real person is watched in diverse location.
Specifically, can be space coordinates corresponding to painting canvas space is set, the eye position of person model is eyes
Position, the three-dimensional coordinate in space coordinates can be used to represent, wherein, the value of Z-dimension can be preset value in three-dimensional coordinate,
The preset value represents eye-level of the person model on level land, and certainly, if person model is moved into some height, this is regarded
Line height value can respective change.In addition, person model by it is front and rear left back mobile when, in the D coordinates value of eye position, X-dimension
Can correspondingly it change with the value of Y dimensions.
At some current time, eye position of the person model in painting canvas space is obtained, also, obtain person model
Direction of visual lines.Direction of visual lines refers to the direction that person model faces, and can be expressed as the angle with some reference direction.Example
Such as, reference direction is the direction of X-dimension, i.e. front, then what direction of visual lines represented is sight and the front of person model
Angle.
Step S102：Be central angle using eye position as summit, predetermined angle, direction of visual lines for central angle direction, really
Determine taper viewing areas, and the region outside conical scan area is defined as non-viewing area.
Wherein, the threedimensional model scene of generation is to need to show the mankind to watch, it is appreciated that human eye has
Certain angular field of view, the numerical value generally between 90 ° to 120 °.Therefore, some numerical value in the range of this can be taken as pre-
If angle.
When in face of some direction, human eye can left back rotation up and down, so as to which the field range watched can
To be considered a conical region.Therefore, the present embodiment is using the eye position of person model as summit, using predetermined angle as
Central angle, determine the viewing areas of a taper.Wherein, the central angle represents the folder between two lines relative in tapered side
Angle.In addition, the taper viewing areas has direction, direction is the direction of visual lines of person model.
In painting canvas space, the region that person model can be watched is defined as taper viewing areas, in addition, remaining area
The region that domain representation person model can not currently be watched, the subregion is defined as non-viewing area.So, it is whole to draw
Cloth space can consider to be made up of two parts, is respectively：Taper viewing areas and non-viewing area.
Step S103：In multiple default threedimensional models, the first kind threedimensional model positioned at taper viewing areas is searched,
And search the Second Type threedimensional model positioned at non-viewing area；Wherein, the fidelity of first kind threedimensional model is higher than second
The fidelity of type three dimensional model.
Wherein, according to the scene of realistic simulation, the threedimensional model for making object in the scene is preset.For example, simulated scenario
For school, teaching building model, playground model, road model, the tree modelling etc. of both sides of the road can be made.Wherein, three-dimensional mould
Type is using existing three-dimensional drawing tool making, such as CAD drawing instruments.
It should be noted that each object can have a two distinct types of threedimensional model, two kinds of threedimensional models are imitated
True degree is different, and a fidelity is higher, and another fidelity is relatively low.For example, the higher teaching building model of fidelity can include three
Window, door and stair etc. are tieed up, or, it can further include word upstairs, pattern etc..On the contrary, the religion that fidelity is relatively low
It can be cube model to learn building module, and door and window of two dimension etc. can be included on cubical side, and not comprising text upstairs
Word and pattern.Certainly, this is only an example, and the application is not limited thereto.
Painting canvas space is divided into taper viewing areas and non-viewing area two parts above, in the higher model of fidelity
In, the model being located in taper viewing areas is searched, the model found is referred to as first kind threedimensional model, also, imitative
Really spend in relatively low model, search the model being located in non-viewing area, the model found is referred to as Second Type three-dimensional mould
Type.
Step S104：In default painting canvas space, first kind threedimensional model and Second Type threedimensional model are shown, is obtained
Target three-dimensional scene.
Wherein, threedimensional model has respective coordinate value, for representing its present position in painting canvas space.Therefore,
Threedimensional model can be placed in painting canvas space according to the coordinate value of threedimensional model, so as to obtain threedimensional model scene, display
Watched to user.
From above technical scheme, this application provides a kind of methods of exhibiting embodiment of threedimensional model scene, this reality
Apply example and be previously provided with painting canvas space, painting canvas is provided with person model in space, after person model is moved to some position, really
The eye position and direction of visual lines of person model are determined, using the eye position as summit, using predetermined angle as central angle, in sight side
Taper viewing areas is built to side, in multiple default threedimensional models, searches the first kind three positioned at taper viewing areas
Dimension module is simultaneously shown, the region outside taper viewing areas is defined as into non-viewing area, and search positioned at non-viewing area
Second Type threedimensional model simultaneously shows, wherein, the fidelity of first kind threedimensional model is higher than Second Type threedimensional model.Can
See, the threedimensional model scene of the present embodiment generation is all not the model of high emulation, but the viewing of analog subscriber is experienced, and will regard
The model that line can not touch region is loaded as the relatively low model of fidelity, and this kind of mode can not only improve the loading of model scene
Efficiency, and the scene shown more conforms to the viewing experience of user.
In above example, whole painting canvas space is divided into two parts, a part is the region of sight in one's power, another portion
It is divided into the too late region of sight, shows the different threedimensional model of fidelity respectively.Further, can also be to the area of sight in one's power
Domain carries out careful division.
It is understood that in actual life, the mankind in the object on watching some direction, object definition with
The increase of viewing distance and be gradually reduced.Therefore, distance threshold can be pre-set, taper viewing areas is divided into two
Point, the different threedimensional model of fidelity is shown respectively.
Specifically, as shown in Fig. 2 in above-described embodiment in step S103 in multiple default threedimensional models, lookup is located at
The specific implementation of the first kind threedimensional model of taper viewing areas includes step S201~step S202.
Step S201：In default refined model storehouse, search positioned at taper viewing areas and between eye position away from
From the threedimensional model not less than pre-determined distance threshold value.
Step S202：In default simple model storehouse, search positioned at taper viewing areas and between eye position away from
From the threedimensional model more than pre-determined distance threshold value, and search the threedimensional model positioned at non-viewing area；
Specifically, before implementation, two model libraries, respectively refined model storehouse and simple model can be pre-set
Storehouse.Whole threedimensional models in the simulated scenario are included in two model libraries, only the fidelity of threedimensional model is different, specifically
Ground, the fidelity of threedimensional model in refined model storehouse is preset, higher than the fidelity of threedimensional model in default simple model storehouse.
For example, the threedimensional model of teaching building is included in refined model storehouse and simple model storehouse, wherein, in refined model storehouse
Teaching building model more emulates, such as floor, door and window, word and pattern comprising three-dimensional etc., teaching building mould in simple model storehouse
Type is cube, and the flooring wall etc. of two-dimension picture expression is posted in cuboid sides.
As known from the above, distance threshold, the distance value that distance threshold simulation people clearly watches are previously provided with.Usually,
The object that human eye can be clearly watched within 50m, therefore, can be according to simulated scenario and the engineer's scale of real scene, to 50m
Ratiometric conversion is carried out, obtains the pre-determined distance threshold value in the application.Certainly, pre-determined distance threshold value can also be other numerical value, and
It is confined to the numerical value.
Started with the summit of taper viewing areas, extend the length of the pre-determined distance threshold value to direction of visual lines, will it is default away from
From the taper viewing areas within threshold value as Part I region, using remaining part in taper viewing areas as first
Subregion.
In refined model storehouse, the model positioned at Part I region is searched, in simple model storehouse, searches and is located at second
The model of subregion.So, taper viewing areas is also divided into two parts, apart from eye position not less than predetermined threshold value away from
From part, it is shown that fine model, the rough model that the part exceeded is shown.This kind of load mode, i.e., by model
The mode being shown in painting canvas, it can further improve the formation efficiency of model scene.
It should be noted that in the Part II region of taper viewing areas model fidelity, non-viewing can be higher than
The fidelity of model in region.Specifically, in addition to refined model storehouse and simple model storehouse are set, transition can also be set
Model library, wherein, the fidelity of model is ordered as in this three model libraries, and refined model storehouse is more than transition model storehouse and is more than roughly
Model library.
In specific implementation, the model in the Part I region of taper viewing areas can be from refined model library lookup to
, the model in the Part I region of taper viewing areas can be found from transition model storehouse, non-viewing area
In model can be found from simple model storehouse.So as to, in the model scene of displaying, trizonal fidelity according to
Secondary reduction, this kind of mode can not only improve loading velocity, and more conform to the viewing impression of user, better user experience.
Careful division has been carried out to taper viewing areas above, certainly, in actual applications, can also be to non-viewing area
Make a distinction.Specifically, although the sight angle of people is less than 180 degree, the area of 180 degree is extended to from sight angle to both sides
Domain, it still can obscure what is watched.
Therefore, as shown in figure 3, for step S103 in multiple default threedimensional models, lookup is located at non-sight in above-described embodiment
Step S301~step S304 can be included by seeing the specific implementation of the Second Type threedimensional model in region.
Step S301：The line centered on direction of visual lines, predetermined angle is divided into two equal subangles, and respectively with regarding
Line position is summit, the complementary angle of subangle is central angle, determines the viewing buffer area of two tapers.
Wherein, the line centered on direction of visual lines, default sight angle is divided into two equal subangles, for example, in advance
If angle is 120 degree, predetermined angle is divided into two 60 degree of subangle by direction of visual lines.Using the complementary angle of subangle as central angle,
Determine the viewing buffer area of two tapers respectively in the both sides of taper viewing areas.For example, subangle is 60 degree, then viewing is slow
The angular dimension for rushing region is 30 degree.
Step S302：Region outside taper viewing areas and two taper viewing buffer areas is defined as non-viewing area
Domain.
Therefore, whole painting canvas space can be further divided into three parts, i.e., taper viewing areas, viewing buffer area,
And non-viewing areas.Wherein, viewing buffer zone and non-viewing areas can be combined as the non-viewing area in flow shown in Fig. 1
Domain.
Step S303：In default refined model storehouse, the threedimensional model positioned at two viewing buffer areas is searched.
Step S304：In default simple model storehouse, the second subtype threedimensional model positioned at non-viewing areas is searched；Its
In, the fidelity of threedimensional model in default refined model storehouse, higher than the fidelity of threedimensional model in default simple model storehouse.
In this implementation, non-viewing areas can be divided into the viewing of two parts, i.e. predetermined angle complementary angle size
Buffer area, and the non-viewing areas of person model behind.The fidelity of threedimensional model in buffer zone is watched, higher than not seeing
The fidelity of threedimensional model in region is seen, can not only improve model loading efficiency, also more conforms to user's viewing experience.
It should be noted that the refined model storehouse in this implementation can also be Fig. 2 illustrate in transition model storehouse, this
Sample, the fidelity of model reduces successively in taper viewing areas, viewing buffer area and non-viewing areas.
Certainly, the refined model storehouse in this implementation can also be the refined model storehouse in figure 2 above, so, taper
Model in viewing areas and buffering viewing areas is fine threedimensional model.When person model is turned round to buffering viewing areas
Afterwards, and model need not be reloaded, displaying efficiency can be improved.But this mode, to the image procossing performance requirement of equipment
It is higher, therefore, apply in the equipment with compared with hi-vision process performance.
Furthermore in addition to the region division more than, can also according to the relation between model, come load some fidelities compared with
Low model, further to improve the displaying efficiency of model scene.
Specifically, in the big object with receiving space, some small objects can be placed.So, the three-dimensional mould of big object
In type, the threedimensional model of some wisps can be loaded.If person model does not watch the big object model closely, the big thing
The wisp model included in body Model can be the relatively low model of fidelity.
Therefore, as shown in figure 4, for step S103 in multiple default threedimensional models, lookup is located at taper in above-described embodiment
The specific implementation of the first kind threedimensional model of viewing areas can include step S401~step S403.
Step S401：In multiple default threedimensional models, the threedimensional model positioned at taper viewing areas is searched.
Step S402：Whether the space body three-dimensional mould with pre-set space mark is included in the threedimensional model for judging to find
Type；If so, perform step S403.
Step S403：Distance between space body three-dimensional models and eye position is more than the situation of default low coverage threshold value
Under, it is determined that the threedimensional model in the space inside the body three-dimensional models of space；Wherein, the fidelity of space body three-dimensional models is high
In the fidelity of threedimensional model in space.
Specifically, before implementation, corresponding mark (free token) is set for big object dimensional model, for the ease of retouching
State, big object model can be referred to as space body three-dimensional models.
First, in the three-dimensional model, all threedimensional models positioned at taper viewing areas are searched, if the three-dimensional mould found
Space body three-dimensional models are included in type, then further determine that distance of the person model apart from the space body three-dimensional models.Should be away from
From compared with default low coverage threshold value, if the former is more than the latter, then it represents that person model watches some in larger distance
Space body Model, then the wisp model for now needing will to include in the body three-dimensional models of space (or three-dimensional mould referred to as in space
Type) it is arranged to the relatively low threedimensional model of fidelity.
Certainly, can be with if the distance of person model metric space body three-dimensional models is less than or equal to default low coverage threshold value
Threedimensional model in space is loaded as fidelity highest threedimensional model, i.e. threedimensional model in refined model storehouse immediately.
As known from the above, in this implementation, the fidelity of threedimensional model in the space that is included in the body three-dimensional models of space
It is relatively low, therefore, it can further improve scene loading efficiency.
In actual applications, in addition to it will be contained in threedimensional model in space and be loaded as the relatively low model of fidelity, may be used also
So to be handled the model being blocked, further to improve scene loading efficiency.
Specifically, as shown in figure 5, step S103 is searched positioned at cone in multiple default threedimensional models in above-described embodiment
The specific implementation of the first kind threedimensional model of shape viewing areas can include step S501~step S503.
Step S501：In multiple default threedimensional models, the threedimensional model positioned at taper viewing areas is searched.
Step S502：Whether included with the default shutter body three-dimensional mould for blocking mark in the threedimensional model for judging to find
Type；If so, perform step S503.
Step S503：Search positioned at the threedimensional model that is blocked blocked on rear side of body three-dimensional models；Wherein, shutter body three-dimensional mould
The fidelity of type, higher than the fidelity for the threedimensional model that is blocked.
Specifically, it is that the threedimensional model that can block other models sets corresponding mark (to block mark before implementation
Note), for the ease of description, the model for blocking other models can be referred to as blocking body three-dimensional models, the model being blocked is claimed
For the threedimensional model that is blocked.
First, in the three-dimensional model, all threedimensional models positioned at taper viewing areas are searched, if the three-dimensional mould found
Comprising body three-dimensional models are blocked in type, then from the point of view of direction of visual lines, by positioned at the three-dimensional that is blocked blocked on rear side of body three-dimensional models
Model, it is defined as fidelity and is less than the threedimensional model for blocking body three-dimensional models fidelity.
It should be noted that blocking body three-dimensional models can find from refined model storehouse, be blocked body three-dimensional
Model can be found from simple model storehouse or transition model storehouse.
, will be out of visual line of sight in this implementation, it is relatively low that the threedimensional model of the object that is blocked is arranged to fidelity
Threedimensional model, the model data amount of loading is smaller, so as to improve the loading velocity of model of place.
In addition, relevant the application has some following supplement.
First, in the prior art, when user checks some model of place, client is the moving operation according to user,
Threedimensional model is obtained from server side in real time to be illustrated in painting canvas space.However, the threedimensional model in the application can be advance
Download from server side, when user wants to check model of place, loaded from the threedimensional model being locally-downloaded, so as to
Further to improve scene loading velocity.
Second, three-dimensional coordinate has respective coordinate value in itself, represents that three-dimensional coordinate is placed on the position in painting canvas space.
A kind of implementation that lookup is located at threedimensional model in some region can determine the coordinate range in the region, by each three
The coordinate value of dimension module is compared with the coordinate range in the region.But in this kind of implementation, not only program needs to write
Complicated calculating logic code, and program amount of calculation is larger, and processing speed is slower.Therefore, another reality of threedimensional model is searched
Existing mode is to call collision function interface.
Specifically, understood from the explanation of above-mentioned relevant Fig. 2 divisions taper viewing areas, it is necessary to use pre-determined distance threshold value
To search threedimensional model.Therefore, sphere model (ball that a radius is pre-determined distance threshold value can be bound in person model
Body Model is arranged to transparent, can't be shown in painting canvas space), the mobile movement that can drive sphere model of person model.
When sphere model and other threedimensional models collide, collision function interface can produce collision accident.Therefore, in person model
When being moved to some position, the opening position call collision function interface, directly search collide function interface in, be with which three
Dimension module produces collision accident, the three-dimensional mould threedimensional model for producing collision accident being defined as within pre-determined distance threshold value
Type.
Certainly, the default low coverage threshold value in Fig. 4 can also represent that the sphere model is also bound using another sphere model
In person model, the event if sphere model does not collide with space body three-dimensional models, representation space body three-dimensional models with
The distance between eye position is more than default low coverage threshold value, says vividerly, is that person model is to watch the space at a distance
Body three-dimensional models, then threedimensional model in the space in the body three-dimensional models of space is arranged to the relatively low model of fidelity.But one
Denier collides event when the sphere model and space body three-dimensional models, represents person model close to the space body three-dimensional models,
Threedimensional model in space is then arranged to the higher model of fidelity.
The mode of collision function interface is called, in program and calculating logic code need not be write, programmed logic is more preferable,
And program amount of calculation is smaller, processing speed is very fast.
The exhibiting device embodiment of the threedimensional model scene provided below the application is introduced, it is necessary to illustrate,
The explanation of exhibiting device embodiment about threedimensional model scene may refer to the displaying side of threedimensional model scene provided above
Method embodiment, is not repeated below.
Referring to Fig. 6, it illustrates the structure of the exhibiting device embodiment of threedimensional model scene.As shown in fig. 6, the three-dimensional mould
The exhibiting device embodiment of type scene can specifically include：Eye position and direction determining mould 601, painting canvas space viewing areas

Type threedimensional model display module 605；Wherein：
Eye position and direction determining mould 601, in default painting canvas space, foundation user to be to presetting person model
Moving operation, it is determined that the eye position and direction of visual lines of default person model；Wherein, shown in default painting canvas space default
Person model；
Painting canvas space viewing region division module 602, for being central angle using eye position as summit, predetermined angle, regarding
Line direction is the direction of central angle, determines taper viewing areas, and the region outside conical scan area is defined as into non-viewing area
Domain；
First kind threedimensional model searching modul 603, in multiple default threedimensional models, searching and being watched positioned at taper
The first kind threedimensional model in region；
Second Type threedimensional model searching modul 604, in multiple default threedimensional models, lookup to be located at non-viewing area
The Second Type threedimensional model in domain；Wherein, the fidelity of first kind threedimensional model is higher than the emulation of Second Type threedimensional model
Degree；
Different type threedimensional model display module 605, in default painting canvas space, showing first kind threedimensional model
And Second Type threedimensional model, obtain target three-dimensional scene.
From above technical scheme, this application provides a kind of exhibiting device embodiment of threedimensional model scene, this reality
To apply example and be previously provided with painting canvas space, painting canvas is provided with person model in space, after person model is moved to some position, depending on
Line position and direction determining mould 601 determine the eye position and direction of visual lines of person model, painting canvas space viewing region division
Module 602 using the eye position as summit, using predetermined angle as central angle, direction of visual lines side build taper viewing areas,
And then first kind threedimensional model searching modul 603 is in multiple default threedimensional models, the positioned at taper viewing areas is searched
One type threedimensional model, and shown by different type threedimensional model display module 605, painting canvas space viewing region division module
