Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present application, be clearly and completely described the technical scheme in the embodiment of the present application, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the application's protection.
See Fig. 1, it illustrates the flow process of the methods of exhibiting embodiment of the three-dimensional model scene that the application provides.As shown in Figure 1, the present embodiment can specifically comprise step S101 ~ step S104.
Step S101: in default painting canvas space, according to the mobile operation of user to default person model, determines eye position and the direction of visual lines of default person model; Wherein, default person model is shown in default painting canvas space.
Wherein, pre-set painting canvas space, and person model is set in painting canvas space, be used for simulating real person and the user of current viewing model scene.User can by the movement of the input device controls such as mouse, keyboard person model, and the present embodiment, according to the shift position of person model, carrys out the different model scene that Reality simulation personage watches at diverse location.
Particularly, can be the space coordinates that painting canvas spatial placement is corresponding, the eye position of person model and the position of eyes, can represent by the three-dimensional coordinate in usage space coordinate system, wherein, in three-dimensional coordinate, the value of Z dimension can be preset value, this preset value represents the eye-level of person model on level land, certainly, if person model is moved into certain height, then this height of sighting line value can respective change.In addition, person model by front and back left back mobile time, in the D coordinates value of eye position, the value of X dimension and Y dimension can correspondingly change.
At certain current time, obtain the eye position of person model in painting canvas space, and, obtain the direction of visual lines of person model.Direction of visual lines refers to the direction faced by person model, can be expressed as the angle with certain reference direction.Such as, reference direction is the direction of X dimension, i.e. dead ahead, then what direction of visual lines represented is the sight line of person model and the angle in dead ahead.
Step S102: take eye position as summit, predetermined angle is central angle, direction that direction of visual lines is central angle, determines taper viewing areas, and the region outside tapered sweep district is defined as non-viewing area.
Wherein, the three-dimensional model scene of generation needs to show the mankind to watch, it is appreciated that human eye has certain angular field of view, is generally the numerical value between 90 ° to 120 °.Therefore, certain numerical value within the scope of this can be got as predetermined angle.
When in the face of certain direction, human eye can upper and lower left back rotation, thus the field range of watching can think a conical region.Therefore, the present embodiment, using the eye position of person model as summit, using predetermined angle as central angle, determines the viewing areas of a taper.Wherein, this central angle represents the angle between two lines relative in tapered side.In addition, this taper viewing areas has direction, and 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, the current region that can not watch of remaining region representation person model, is defined as non-viewing area by this subregion.Like this, whole painting canvas space can be thought and to be made up of two parts, is respectively: taper viewing areas and non-viewing area.
Step S103: in multiple default three-dimensional model, searches the first kind three-dimensional model being positioned at taper viewing areas, and searches the Second Type three-dimensional model being positioned at non-viewing area; Wherein, the fidelity of first kind three-dimensional model is higher than the fidelity of Second Type three-dimensional model.
Wherein, according to the scene of realistic simulation, preset the three-dimensional model making object in this scene.Such as, simulated scenario is school, can make the tree modelling etc. of teaching building model, playground model, road model, road both sides.Wherein, three-dimensional model uses existing three-dimensional drawing tool making, as CAD drawing instrument.
It should be noted that, each object can have two kinds of dissimilar three-dimensional models, and the fidelity of two kinds of three-dimensional models is different, and a fidelity is higher, and another fidelity is lower.Such as, the teaching building model that fidelity is higher can comprise three-dimensional window, door and stair etc., or, can further include word upstairs, pattern etc.On the contrary, the teaching building module that fidelity is lower can be cube model, cubical side can comprise the door and window etc. of two dimension, and the word do not comprised upstairs and pattern.Certainly, this is only an example, and the application is not limited thereto.
Be taper viewing areas and non-viewing area two parts above by painting canvas spatial division, in the model that fidelity is higher, search the model being arranged in taper viewing areas, the model found is called first kind three-dimensional model, and, in the model that fidelity is lower, search the model being arranged in non-viewing area, the model found is called Second Type three-dimensional model.
Step S104: in default painting canvas space, display first kind three-dimensional model and Second Type three-dimensional model, obtain target three-dimensional scene.
Wherein, three-dimensional model has respective coordinate figure, for representing its present position in painting canvas space.Therefore, according to the coordinate figure of three-dimensional model, three-dimensional model can be placed in painting canvas space, thus obtain three-dimensional model scene, be shown to user's viewing.
From above technical scheme, this application provides a kind of methods of exhibiting embodiment of three-dimensional model scene, the present embodiment is previously provided with painting canvas space, painting canvas is provided with person model in space, after person model moves to certain position, determine eye position and the direction of visual lines of person model, with this eye position for summit, take predetermined angle as central angle, taper viewing areas is built in direction of visual lines side, in multiple default three-dimensional model, search the first kind three-dimensional model that is positioned at taper viewing areas and show, region outside taper viewing areas is defined as non-viewing area, and search the Second Type three-dimensional model that is positioned at non-viewing area and show, wherein, the fidelity of first kind three-dimensional model is higher than Second Type three-dimensional model.Visible, the three-dimensional model scene that the present embodiment generates is all not the model of high emulation, but the viewing of analog subscriber impression, the model that sight line can not be touched region is loaded as the lower model of fidelity, this kind of mode not only can improve the loading efficiency of model scene, and the scene of showing meets the viewing experience of user more.
In above embodiment, be two parts by whole painting canvas spatial division, a part is sight line region in one's power, and another part is the too late region of sight line, shows the three-dimensional model that fidelity is different respectively.Further, careful division can also be carried out to sight line region in one's power.
Be understandable that, in actual life, the mankind are when watching the object on certain direction, and object sharpness reduces gradually along with the increase of viewing distance.Therefore, can distance threshold be pre-set, so that taper viewing areas is divided into two parts, show the three-dimensional model that fidelity is different respectively.
Particularly, as shown in Figure 2, in above-described embodiment in step S103 in multiple default three-dimensional model, the specific implementation of searching the first kind three-dimensional model being positioned at taper viewing areas comprises step S201 ~ step S202.
Step S201: in default refined model storehouse, search at taper viewing areas and and distance between eye position do not exceed the three-dimensional model of predeterminable range threshold value.
Step S202: in default simple model storehouse, search at taper viewing areas and and distance between eye position exceed the three-dimensional model of predeterminable range threshold value, and search the three-dimensional model being positioned at non-viewing area;
Specifically, before enforcement, two model banies can be pre-set, be respectively refined model storehouse and simple model storehouse.Comprise the whole three-dimensional models in this simulated scenario in two model banies, only the fidelity of three-dimensional model is different, particularly, presets the fidelity of three-dimensional model in refined model storehouse, higher than the fidelity of three-dimensional model in default simple model storehouse.
Such as, the three-dimensional model of teaching building is all comprised in refined model storehouse and simple model storehouse, wherein, in refined model storehouse, teaching building model emulates more, such as comprise three-dimensional floor, door and window, word and pattern etc., in simple model storehouse, teaching building model is cube, cuboid sides is posted the flooring body of wall etc. that two-dimension picture represents.
As known from the above, be previously provided with distance threshold, the distance value of the clear viewing of distance threshold simulation people.Usually, human eye can object within clear viewing 50m, therefore, according to the engineer's scale of simulated scenario and real scene, can carry out ratiometric conversion to 50m, the predeterminable range threshold value in acquisition the application.Certainly, predeterminable range threshold value can also be other numerical value, and is confined to this numerical value.
Start with the summit of taper viewing areas, extend the length of this predeterminable range threshold value to direction of visual lines, using the taper viewing areas within predeterminable range threshold value as Part I region, using part remaining in taper viewing areas as Part I region.
In refined model storehouse, search the model being positioned at Part I region, in simple model storehouse, search the model being positioned at Part II region.Like this, taper viewing areas is also divided into two parts, and distance eye position does not exceed the part of predetermined threshold value distance, display be meticulous model, the rough model of the part display exceeded.This kind of load mode, by the mode of models show in painting canvas, can improve the formation efficiency of model scene further.
It should be noted that, the fidelity of model in the Part II region of taper viewing areas, can higher than the fidelity of model in non-viewing area.Specifically, except arranging refined model storehouse and simple model storehouse, can also arrange transition model storehouse, wherein, in these three model banies, the fidelity sequence of model is that refined model storehouse is greater than transition model storehouse and is greater than simple model storehouse.
In concrete enforcement, model in the Part I region of taper viewing areas can from refined model library lookup to, model in the Part I region of taper viewing areas can find from transition model storehouse, and the model in non-viewing area can find from simple model storehouse.Thus in the model scene of displaying, trizonal fidelity reduces successively, this kind of mode not only can improve loading velocity, and more meets the viewing impression of user, better user experience.
Above careful division is carried out to taper viewing areas, certainly, in actual applications, can also distinguish non-viewing area.Particularly, although the sight angle of people is less than 180 degree, extend to the region of 180 degree from sight angle to both sides, still can fuzzyly watch.
Therefore, as shown in Figure 3, in above-described embodiment, step S103 is in multiple default three-dimensional model, and the specific implementation of searching the Second Type three-dimensional model being positioned at non-viewing area can comprise step S301 ~ step S304.
Step S301: line centered by direction of visual lines, is divided into two equal subangles by predetermined angle, and be summit respectively with eye position, the complementary angle of subangle is central angle, determines the viewing buffer area of two tapers.
Wherein, line centered by direction of visual lines, default sight angle is divided into two equal subangles, such as, predetermined angle is 120 degree, and predetermined angle is divided into the subangle of two 60 degree 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.Such as, subangle is 60 degree, then the angular dimension watching buffer area is 30 degree.
Step S302: the region outside taper viewing areas and two taper viewing buffer areas is defined as non-viewing areas.
Therefore, whole painting canvas space can Further Division be 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 process shown in Fig. 1.
Step S303: in default refined model storehouse, searches the three-dimensional model being positioned at two viewing buffer areas.
Step S304: in default simple model storehouse, searches the second subtype three-dimensional model being positioned at non-viewing areas; Wherein, the fidelity of three-dimensional model in refined model storehouse is preset, higher than the fidelity of three-dimensional model in default simple model storehouse.
In this implementation, non-viewing areas can be divided into two parts, i.e. the viewing buffer area of predetermined angle complementary angle size, and person model non-viewing areas behind.In viewing buffer zone, the fidelity of three-dimensional model, higher than the fidelity of three-dimensional model in non-viewing areas, not only can improve model loading efficiency, also more meet user's viewing experience.
It should be noted that, the refined model storehouse in this implementation also can be the transition model storehouse during Fig. 2 illustrates, like this, in taper viewing areas, viewing buffer area and non-viewing areas, the fidelity of model reduces successively.
Certainly, the refined model storehouse in this implementation also can be the refined model storehouse above in Fig. 2, and like this, the model in taper viewing areas and buffering viewing areas is meticulous three-dimensional model.When person model is turned round to buffering viewing areas, do not need to reload model, displaying efficiency can be improved.But this mode, higher to the image procossing performance requirement of equipment, therefore, be applied on the equipment that has compared with hi-vision handling property.
Moreover, except above Region dividing, according to the relation between model, the lower model of some fidelities can also be loaded, to improve the displaying efficiency of model scene further.
Particularly, have in the large object of spatial accommodation, the object that some are little can be placed.Like this, in the three-dimensional model of large object, the three-dimensional model of some wisps can be loaded.If person model does not closely watch this large object model, then the wisp model comprised in this large object model can be the model that fidelity is lower.
Therefore, as shown in Figure 4, in above-described embodiment, step S103 is in multiple default three-dimensional model, and the specific implementation of searching the first kind three-dimensional model being positioned at taper viewing areas can comprise step S401 ~ step S403.
Step S401: in multiple default three-dimensional model, search the three-dimensional model being positioned at taper viewing areas.
Step S402: judge whether comprise the space body three-dimensional model with pre-set space mark in the three-dimensional model found; If so, step S403 is performed.
Step S403: the distance between space body three-dimensional model and eye position is greater than default low coverage threshold value, determines the space three-dimensional model being positioned at space body three-dimensional model inside; Wherein, the fidelity of space body three-dimensional model, higher than the fidelity of three-dimensional model in space.
Specifically, before enforcement, for large object dimensional model arranges corresponding mark (free token), for convenience of description, large object model can be called space body three-dimensional model.
First, in the three-dimensional model, search all three-dimensional models being positioned at taper viewing areas, if comprise space body three-dimensional model in the three-dimensional model found, then determine the distance of person model apart from this space body three-dimensional model further.This distance and the low coverage threshold value preset are compared, if the former is greater than the latter, then represent that person model watches certain space body model in larger distance, then now need the wisp model comprised in space body three-dimensional model (or being called three-dimensional model in space) to be set to the lower three-dimensional model of fidelity.
Certainly, if when the distance of person model metric space body three-dimensional models is less than or equal to default low coverage threshold value, immediately three-dimensional model in space can be loaded as the highest three-dimensional model of fidelity, the three-dimensional model namely in refined model storehouse.
As known from the above, in this implementation, in the space comprised in space body three-dimensional model, the fidelity of three-dimensional model is lower, therefore, can improve scene loading efficiency further.
In actual applications, except being loaded as except the lower model of fidelity by being included in three-dimensional model in space, can also the model be blocked so be processed, to improve scene loading efficiency further.
Particularly, as shown in Figure 5, in above-described embodiment, step S103 is in multiple default three-dimensional model, and the specific implementation of searching the first kind three-dimensional model being positioned at taper viewing areas can comprise step S501 ~ step S503.
Step S501: in multiple default three-dimensional model, search the three-dimensional model being positioned at taper viewing areas.
Step S502: judge whether comprise the shutter body three-dimensional model having and preset and block mark in the three-dimensional model found; If so, step S503 is performed.
Step S503: search the three-dimensional model that is blocked be positioned on rear side of shutter body three-dimensional model; Wherein, the fidelity of shutter body three-dimensional model, higher than the fidelity of the three-dimensional model that is blocked.
Specifically, before enforcement, for the three-dimensional model that can block other models arranges corresponding mark (blocking mark), for convenience of description, the model blocking other models can be called shutter body three-dimensional model, the model be blocked is called the three-dimensional model that is blocked.
First, in the three-dimensional model, search all three-dimensional models being positioned at taper viewing areas, if comprise shutter body three-dimensional model in the three-dimensional model found, then from direction of visual lines, to the three-dimensional model that is blocked on rear side of shutter body three-dimensional model be positioned at, be defined as the three-dimensional model of fidelity lower than shutter body three-dimensional model fidelity.
It should be noted that, shutter body three-dimensional model can find from refined model storehouse, and the body three-dimensional models that is blocked can find from simple model storehouse or transition model storehouse.
In this implementation, will from visual line of sight, the three-dimensional model of the object that is blocked is set to the lower three-dimensional model of fidelity, and the model data amount of loading is less, thus can improve the loading velocity of model of place.
In addition, relevant the application have following some supplement.
The first, in the prior art, when user checks certain model of place, client is the mobile operation according to user, obtains three-dimensional model be in real time illustrated in painting canvas space from server side.But the three-dimensional model in the application can download from server side in advance, when user wants to check model of place, load from the three-dimensional model that this locality is downloaded, thus scene loading velocity can be improved further.
The second, three-dimensional coordinate itself has respective coordinate figure, represents that three-dimensional coordinate is placed on the position in painting canvas space.Searching a kind of implementation being arranged in certain region three-dimensional model can be determine the coordinate range in this region, the coordinate figure of each three-dimensional model and the coordinate range in this region is compared.But in this kind of implementation, not only program needs to write complicated computational logic code, and program computation amount is comparatively large, and processing speed is slower.Therefore, another implementation of searching three-dimensional model calls collision function interface.
Particularly, divide the explanation of taper viewing areas known from above-mentioned relevant Fig. 2, need to use predeterminable range threshold value to search three-dimensional model.Therefore, can bind the sphere model (this sphere model is set to transparent, can't be presented in painting canvas space) that a radius is predeterminable range threshold value in person model, the movement of person model can drive the movement of sphere model.When sphere model and other three-dimensional models collide, collision function interface can produce collision accident.Therefore, when person model moves to certain position, call collision function interface in this position, directly search in collision function interface, be which three-dimensional model to produce collision accident with, the three-dimensional model producing collision accident is defined as the three-dimensional model within predeterminable range threshold value.
Certainly, default low coverage threshold value in Fig. 4 also can use another sphere model to represent, this sphere model is also bundled in person model, the event if this sphere model does not collide with space body three-dimensional model, distance between representation space body three-dimensional models and eye position is greater than default low coverage threshold value, say, to be person model be at remote this space body three-dimensional model of viewing, then three-dimensional model in the space in space body three-dimensional model is set to the lower model of fidelity vividerly.But once when this sphere model and space body three-dimensional model collide event, three-dimensional model in space close to this space body three-dimensional model, is then set to the higher model of fidelity by expression person model.
Call the mode of collision function interface, do not need to write computational logic code in program, programmed logic is better, and program computation amount is less, and processing speed is very fast.
Below the exhibiting device embodiment of the three-dimensional model scene that the application provides is introduced, it should be noted that, the explanation of the exhibiting device embodiment of regarding three-dimensional model scene see the methods of exhibiting embodiment of three-dimensional model scene provided above, can not repeat below.
