Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
Fig. 1 is the method flow diagram according to the present invention for limiting VR helmet tracking range, below with reference to Fig. 1, to this hair
The method of bright restriction VR helmet tracking range is described in detail.
In step 101, increase by one and initial helmet coordinate shift amount etc. in the current helmet coordinate data tracked
The reserve migration amount of value corrects the initial offset of the coordinate of player and carrier.
In the step, in original state, after player binds game role and carrier, helmet tracing module record is chased after
The initial helmet coordinate that track arrives offset (i.e. original state when player and carrier coordinate shift amount), helmet output module is defeated
Increase by one and the reserve migration amount of initial helmet coordinate shift amount equivalence in current helmet coordinate data out, obtains video camera
The offset of the current helmet coordinate obtained is 0.By above-mentioned adjustment, when original state, in the feedback visual angle of video camera, player
Offset visual angle with carrier is 0.
In step 102, whether within a preset range current helmet coordinate shift amount is judged, be to then follow the steps 103, otherwise
Execute step 104.Wherein, the preset range of current helmet coordinate shift amount can need to set according to player.
In the step, judge current helmet coordinate shift amount (i.e. current state when player and carrier coordinate shift amount) be
It is no within a preset range, can by set restriction sign position be judged.Set the concrete mode of restriction sign position are as follows: at certain
Restriction sign position is set in one or several reference axis, (horizontal plane is sat for example, restriction sign position is set in X, Y coordinates axis
Parameter) on, and with no restrictions to Z coordinate axis (height coordinate axis).
In step 103, current helmet coordinate shift amount within a preset range when, keep increasing in current helmet coordinate data
It is constant with the reserve migration amount of initial helmet coordinate shift amount equivalence.
In the step, when normal condition player is located at progress game on carrier, tracked when helmet tracing module
Current helmet coordinate shift amount within a preset range when, helmet output module output with keep in current helmet coordinate data
The reserve migration amount for increasing initial helmet coordinate shift amount equivalence is constant, the current helmet coordinate data for obtaining video camera, energy
The motion state on enough true reflection player heads, makes player in the feedback visual angle of video camera, experiences the motion state of itself
(all complete expression such as movement, rotation of the helmet tracked is in game visual angle).
It is further added by current helmet coordinate data when current helmet coordinate shift amount exceeds preset range in step 104
One current helmet coordinate exceeds the reserve migration amount of preset range offset equivalence.
In the step, when egression player is located at progress game on carrier, tracked when helmet tracing module
When current helmet coordinate shift amount exceeds preset range, helmet output module output with keep in current helmet coordinate data
Increase initial helmet coordinate shift amount equivalence reserve migration amount it is constant except, also need to be further added by one it is super with current helmet coordinate
The reserve migration amount of preset range offset equivalence out, the current helmet coordinate data for obtaining video camera, will not show object for appreciation
The state that family deviates with carrier, makes player in the feedback visual angle of video camera, while the motion state for experiencing itself, and
The feeling for deviateing carrier will not be generated.
