Control module, for controlling the virtual objects that the effect for zooming in or out is presented at the shooting interface of the camera
Really.
7. virtual objects as claimed in claim 6 are presented effect control device, it is characterised in that the virtual objects are presented effect
Fruit control device also includes：
Coordinate obtaining module, the coordinate for obtaining the virtual objects；
Visual angle direction vector acquisition module, the visual angle direction vector for obtaining the camera；
The control module includes：
Rendering module, for according to the coordinate, visual angle direction vector, X-axis, Y-axis, the acceleration of Z axis, in X-axis, Y-axis, Z
The displacement increment of axle and default scaling render the virtual objects.
8. virtual objects as claimed in claim 6 are presented effect control device, it is characterised in that when the camera with it is described
When the distance of virtual objects becomes big, the camera controls the virtual objects in the camera away from the virtual objects
Shoot interface present reduce effect；When the camera becomes hour with the distance of the virtual objects, the camera is leaned on
The nearly virtual objects, control the virtual objects in the effect that interface is presented amplification that shoots of the camera.
9. virtual objects as claimed in claim 8 are presented effect control device, it is characterised in that the virtual objects are presented effect
Fruit control device also includes：
Judge module, for foundation the X-axis, Y-axis, the displacement increment of Z axis and acceleration judge the camera with it is described
The distance of virtual objects becomes big or diminishes.
10. virtual objects as claimed in claim 6 are presented effect control device, it is characterised in that the displacement increment is calculated
Module is used for according to formula Δ Lxi=0.5 × axi×Δti 2, Δ Lyi=0.5 × (ayi-g)×Δti 2, Δ Lzi=0.5 × azi
×Δti 2The displacement increment on X-axis, Y-axis, Z axis is calculated respectively；Wherein, Δ tiIt is the time interval of ith sample point, axi,
ayi, aziIt is ith sample point acceleration respectively on X-axis, Y-axis, Z axis, g is acceleration of gravity, Δ Lxi、ΔLyi、ΔLzi
It is ith sample point displacement increment respectively on X-axis, Y-axis, Z axis.
