Description
Technical field
The present invention relates to computer software fields, more particularly to a kind of Virtual Space method and apparatus.
Background technology
Augmented reality (Augmented Reality, abbreviation AR), be it is a kind of in real time calculate camera image position and
Angle and the technology for adding respective image, the target of this technology is that virtual world is sleeved on real world on the screen and is carried out
It is interactive.
Augmented reality skill is originally existing by " seamless " the integrated new technology of real world information and virtual world information
It is difficult the entity information (visual information, sound, taste, tactile etc.) experienced in the certain time spatial dimension in the real world, leads to
The science and technology such as computer are crossed, are superimposed again after analog simulation, virtual Information application to real world is felt by human sensory
Know, to reach the sensory experience of exceeding reality.True environment and virtual object have been added to the same picture in real time
Or space exists simultaneously.It not only presents the information of real world, but also virtual information is shown simultaneously, two kinds of letters
Breath is complementary to one another, is superimposed.In the augmented reality of visualization, user utilizes Helmet Mounted Display, real world and computer graphic
It is multiple to be synthesized together, the true world can be seen around it.
Augmented reality contain multimedia, three-dimensional modeling, real-time video show and control, Multi-sensor Fusion, reality
When track and registration, scene fusion etc. new technologies and new tool.Augmented reality provides under normal circumstances, can different from the mankind
With the information of perception.This technology is most proposed earlier than nineteen ninety.With the promotion of accompanied electronic product operational capability, augmented reality
Purposes it is more and more wider.
The current Virtual Spaces AR interaction schemes are mostly object to be superimposed in realistic space, and traditional AR experience is mostly
In order to show some object and generate interaction with it.
Invention content
For this reason, it may be necessary to which providing a kind of new AR interactive modes can naturally be worn back and forth with realizing in Virtual Space and realistic space
The function of shuttle switching.
To achieve the above object, a kind of Virtual Space method is inventor provided, is included the following steps：
By the model carry in virtual scene to Virtual Space origin；
Ambient is set along Virtual Space periphery, the ambient does not overlap with Virtual Space and surrounds virtual scene
Region except entrance；The rendering prior to the ambient is rendered to the entrance of the Virtual Space；
The first collision object of setting simultaneously places it in Virtual Space entrance, and the size of the first collision object enters with Virtual Space
Mouth size is identical；Setting the second collision object is in virtual camera；
Setting Virtual Space entrance initial state value is false, and when virtual camera enters void from the Virtual Space entrance
When quasi- space, it is true to change its state value；
It is fictitious time when virtual camera enters Virtual Space and Virtual Space entrance initial value, triggers collision accident, hide
Other models in Virtual Space in addition to entrance；When virtual camera leaves Virtual Space, event is left in triggering, shows quilt
Hiding all models, and Virtual Space entrance initial state value is set to false as.
Further, in the Virtual Space method, in step " by the model carry in virtual scene to Virtual Space
Further include step before origin "：The threedimensional model bottom centre point of Virtual Space entrance is set as Virtual Space origin, and with institute
It is virtual scene father node to state Virtual Space origin.
Further, in the Virtual Space method, the ambient is by following processing：
Channel mask is set as 0, and Color Channel is not written into any result；
Only object is rendered when the depth of object is less than or equal to the depth value of itself；
To the rendering of the ambient prior to other opaque articles in addition to the entrance of Virtual Space.
Further, in the Virtual Space method, the second collision object is preset as ensureing itself and other collision objects
The size of crash response is triggered when colliding enough.
Inventor proposes a kind of Virtual Space device, including model carry unit, ambient setting unit, rendering simultaneously
Unit, collision object setting unit, state value setting unit and hit-treatment unit；
The model carry unit is used for the model carry in virtual scene to Virtual Space origin；
The ambient setting unit be used for along Virtual Space periphery be arranged ambient, the ambient not with Virtual Space
It overlaps and surrounds the region except virtual scene entrance；The rendering unit is for rendering default object, and rendering unit
The rendering prior to the ambient is rendered to the entrance of the Virtual Space；
For the first collision object to be arranged and places it in Virtual Space entrance, described first touches the collision object setting unit
The size for hitting object is identical as Virtual Space entrance size；The collision object setting unit is additionally operable to setting the second collision object in virtual
Video camera；
The state value setting unit is false for Virtual Space entrance initial state value to be arranged, and when virtual camera from
When the Virtual Space entrance enters Virtual Space, it is true that the state value setting unit, which changes its state value,；
The hit-treatment unit is used to when virtual camera enters Virtual Space and Virtual Space entrance initial value be false
When triggering collision accident and hide other models in addition to entrance in Virtual Space；The hit-treatment unit is additionally operable to when void
Event is left in triggering when quasi- video camera leaves Virtual Space, shows that all models being hidden, state value setting unit will be virtual
Space entry initial state value is set to false as.
Further, in the Virtual Space device, the model carry unit is by the model carry in virtual scene
To before the origin of Virtual Space, the threedimensional model bottom centre point of Virtual Space entrance is set as Virtual Space origin, and with
The Virtual Space origin is virtual scene father node.
Further, further include ambient processing unit in the Virtual Space device, for being done to the ambient
Following processing：
Channel mask is set as 0, and Color Channel is not written into any result；
Only object is rendered when the depth of object is less than or equal to the depth value of itself；
To the rendering of the ambient prior to other opaque articles in addition to the entrance of Virtual Space.
Further, in the Virtual Space device, the second collision object is preset as ensureing itself and other collision objects
The size of crash response is triggered when colliding enough.
It is different from the prior art, above-mentioned technical proposal can be used by being superimposed a Virtual Space in realistic space
Family can only be shuttled switching by mobile device in Virtual Space and realistic space, and transition effect is natural.Skill of the present invention
The AR interactions of art scheme can be generated with Virtual Space and be interacted, and be roamed in Virtual Space using the space orientation of AR.In void
In quasi- space, realistic space can just be seen by only penetrating the space of transmission gate, and be needed in realistic space through transmission gate
It can see Virtual Space, the realization for effect of not exposing the false is ensure that with this.
