Using the final spherical rotary component rotation process is carried out to described put on object.
Further, the step of transformation matrix for calculating player, including,
By player towards crown direction, right-hand direction is as coordinate system；
Successively using player towards, crown direction, right-hand direction as the first row row vector, the second every trade vector, third every trade
Vector calculates transformation matrix.
Further, described the step of obtaining spherical rotary component is that the transformation matrix of the player is decomposited rotating part
It is allocated as the spherical rotary component for player.
Further, the transformation matrix by the player decomposes, and is the mathematic decomposition method using matrix, removes the object for appreciation
The translational component and scaling component of the transformation matrix of family, extract the spherical rotary component of player.
Further, the step of acquisition final spherical rotary component is using following formula:
R=Rvisual*Rsphere
Wherein, R is final spherical rotary component, RvisualTo put the existing rotational component of object, RsphereFor the spherical surface of player
Rotational component.
To achieve the above object, the present invention also provides a kind of computer readable storage mediums, are stored thereon with computer and refer to
It enables, described in any item object's positions as described above is executed when the computer instruction is run and are walked towards adaptive approach
Suddenly.
To achieve the above object, described to deposit the present invention also provides a kind of gaming terminal device, including memory and processor
The computer instruction run on the processor is stored on reservoir, the processor executes when running the computer instruction
Object's position as described above is towards adaptive approach step.
A kind of object's position of the invention has the advantages that towards adaptive approach
1) when object is put in any position of global world, the direction and position for putting object have reasonability.
2) player exercises can be responded, player's expected reasonable impression in gaming is provided.
Other features and advantages of the present invention will be illustrated in the following description, also, partly becomes from specification
It obtains it is clear that understand through the implementation of the invention.
Detailed description of the invention
Attached drawing is used to provide further understanding of the present invention, and constitutes part of specification, and with it is of the invention
Embodiment together, is used to explain the present invention, and is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is object's position according to the present invention towards adaptive approach flow chart；
Fig. 2 is object's position according to the present invention towards one schematic diagram of adaptive approach embodiment.
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 object's position according to the present invention towards adaptive approach flow chart, below with reference to Fig. 1, to the present invention
Object's position be described in detail towards adaptive approach.
Firstly, any position in three-dimensional global world selects to put object towards a direction in step 101.
In this step, the direction for putting object may be mistake from the angle of player, need to change by calculating and applying pendulum
The direction for putting object, which makes this put the position and orientation of object, has reasonability from the angular observation of player.
Step 102, calculate and obtain the transformation matrix of player.Use player's face direction Vlookat, crown direction VupThe right side and
Hand direction VrightEstablish coordinate system；By MsphereIt is set as unit matrix, then successively by Vlookat、Vup、VrightIt is set as Msphere's
The first row row vector, the second every trade vector, the third line row vector calculate the transformation matrix M of playersphere；
In step 103, the transformation matrix M of the player is obtainedsphereDecomposite spherical rotary component.Wherein, from transformation matrix
MsphereIn decomposite rotating part as spherical rotary components Rsphere, decomposition method is the mathematic decomposition method using matrix, is moved
Except transformation matrix MsphereTranslational component and scaling component, extract spherical rotary components Rsphere.Use the mathematics side of matrix
Method obtains the rotational component of transformation matrix, and method is simple, easy to operate；Rotational component is decomposited, in order to revolve the spherical surface
Turn components RsphereApplied to putting object.It realizes and puts the reasonability of object's position and direction from player's angular observation.
In step 104, by spherical rotary components RsphereIt is applied to and puts on object, carry out rotation process to object is put.
The application method is that the existing spherical rotary components R of object is put in extractionvisual(extracting method and said extracted spherical rotary point
Measure RsphereIt is identical), calculate final rotational component R=Rvisual * Rsphere, R is set to put the new spherical rotary of object
Component carries out rotation process to object is put.Rotation process is carried out to object is put, so that this puts the position of object and direction
With reasonability.It is correctly, to provide player's sight in terms of player's angle in this way, putting position and the direction of object after modification
Expected reasonable impression when survey.
Fig. 2 is a kind of object's position according to the present invention towards one schematic diagram of adaptive approach embodiment.
As shown in Fig. 2, can be changed in the world in three-dimensional spherical shape, left figure is using before the present invention, and player's trial is put one and stood
Cube, cube direction in global scope is consistent with sphere, but from the point of view of player's angle, cube is inclination mistake.
Smiling face in figure represent player position present in three-dimensional global world and towards direction, firstly, using player in ball
On face towards Vlookat, overhead is to Vup, right-hand direction VrightAs coordinate system, the transformation matrix of player is calculated
MsphereIf the transformation matrix MsphereFor unit matrix, if VlookatFor MsphereThe first row row vector, if VupFor MphereThe
Two every trade vectors, if VlookatFor MsphereThe third line row vector calculates the transformation matrix M of playersphereAfterwards, remove player's
Transformation matrix MsphereTranslational component and scaling component, extract the rotational component R of playersphere.Secondly, using on cube
Main view Dlookat, overhead is to Dup, right direction DrightAs coordinate system, the transformation matrix M of cube is calculatedvisualIf
The transformation matrix MvisualFor unit matrix, if DlookatFor MvisualThe first row row vector, if DupFor MvisualSecond every trade to
Amount, if DlookatFor MvisualThe third line row vector calculates the transformation matrix M of cubevisualAfterwards, the transformation square of cube is removed
Battle array MvisualTranslational component and scaling component, extract the existing spherical rotary components R of cubevisual.Finally, calculating cube
Final spherical rotary components R=R of bodyvisual*Rspher, player according to the final rotational component rotation process cube of cube,
Keep direction that cube is last and position as shown on the right, is correctly, to provide player in gaming from the point of view of player
It is expected that reasonable impression.
Preferably, the present invention also provides a kind of computer readable storage mediums, are stored thereon with computer instruction, the meter
Described in any item object's positions as described above are executed towards adaptive approach step when the instruction operation of calculation machine.
Preferably, it the present invention also provides a kind of gaming terminal device, including memory and processor, is stored up on the memory
