Optionally, the location information of the picture may include the transverse location of the picture and the height of the picture in a three-dimensional display effect, and the distance between a plane where the picture lies and a plane where the screen of the electronic device lies in the three-dimensional display effect.

The movement speed may be the speed at which the user's finger is sliding on the screen of the electronic device, when the finger is being moved on the screen of the electronic device. The attenuation period of time may be determined from the speed at which the user's finger is sliding on the screen of the electronic device, and the attenuation period of time will be longer when the user's finger is sliding at a higher speed, and the attenuation period of time will be shorter when the user's finger is sliding at a lower speed.
In the method for displaying a picture according to the embodiment of the present disclosure, at least one picture sequence number is obtained and substituted into a preset set of equations, to calculate location information of at least one picture, and then the at least one picture is displayed on a screen of an electronic device, according to the location information of the at least one picture. Thus the picture being browsed by a user through software of the electronic device may be displayed three-dimensionally on the screen of the electronic device, based upon a three-dimensional mathematical model indicated by a preset set of equations, to thereby address the problems of a long modeling period of time and inefficient modeling, when the picture is three-dimensionally displayed.
Another embodiment of the present disclosure provides a method for displaying a picture, based upon the embodiment corresponding to FIG. 1 above. Optionally a three-dimensional mathematical model indicated by a preset set of equations is a helical model. An embodiment will be described taking a helical model as an example, but the present disclosure will not be limited thereto. Referring to FIG. 2, the method includes the following operations.
S201 is to obtain at least one picture sequence number.
Among the at least one picture sequence number, a picture sequence number corresponds to a picture. Optionally, the picture corresponding to the at least one picture sequence number may be a picture to be displayed, by the electronic device, on a screen of the electronic device at some instance of time.
Optionally, the electronic device may be a handset, a tablet computer or another electronic device, but the present disclosure will not be limited thereto.

S202 is to substitute the at least one picture sequence number into a preset set of equations to calculate location information of at least one picture.
This embodiment will be described by taking the preset set of equations being a first set of equations as an example, the first set of equations including a first equation x=r cos(θ×i+t), a second equation z=r sin(θ×i+t) and a third equation y=h×i+h×t/θ. The location information of the at least one picture includes the coordinate on the x axis, the coordinate on the y axis and the coordinate on the z axis in a virtual three-dimensional coordinate system.
FIG. 3 illustrates the display effect of the picture corresponding to the first set of equations. The first set of equations corresponds to a mathematical model which is a cylinder model as illustrated in FIG. 4. A plane where the screen of the electronic device lies is in front of the cylinder and tangential to the side surface of the cylinder, and also the plane where the screen of the electronic device lies is perpendicular to the bottom of the cylinder; and in the pre-created virtual three-dimensional coordinate system, the origin of the virtual three-dimensional coordinate system is the center of the circle on the bottom surface of the cylinder, the x axis and the z axis lie in radial directions of the bottom surface of the cylinder respectively, and the y axis is the central axis of the cylinder. Optionally, x may represent the transverse location of the picture in the three-dimensional display effect, y may represent the height of the picture in the three-dimensional display effect, and z may represent the distance between a plane where the picture lies and the plane where the screen of the electronic device lies in the three-dimensional display effect; i represents the picture sequence number, i≧1, and i is an integer; r represents the radius of the cylinder; θ represents the central angle between projections, of two pictures adjacent in the x axis direction, onto the xoz plane in the virtual three-dimensional coordinate system; h represents the difference, in the y axis direction, between the two pictures adjacent in the x axis direction in the virtual three-dimensional coordinate system; and t represents the angle at which the picture is rotated, with the y axis being a rotation axis, in the three-dimensional display effect, and t is initially zero.
In an embodiment of the present disclosure, when the picture is three-dimensionally displayed in the cylinder model, the y axis of the coordinate system is the rotation axis, and if the picture is rotated toward the positive direction of the x axis, then the value of t is positive, and if the picture is rotated toward the negative direction of the x axis, then the value of t is negative.
Further, optionally the location information of the at least one picture further includes: the angle between the plane where the picture lies and the plane where the screen of the electronic device lies in the three-dimensional display effect, and as illustrated in FIG. 4, the cylinder is halved by the plane, where the screen of the electronic device lies, along the diameter of the cylinder of the three-dimensional mathematical model, and the set of equations corresponding to the helical model further includes a fourth equation α=θ×i+t, herein α represents the angle between the plane where the picture lies and the plane where the screen of the electronic device lies in the three-dimensional display effect, and θ represents the angle between two adjacent pictures in the three-dimensional display effect.
S203 is to display the at least one picture according to the location information of the at least one picture.
Optionally the location information of the picture includes coordinate values of the picture on the x axis, the y axis and the z axis in the pre-created virtual three-dimensional coordinate system, and the angle α between the plane where the picture lies and the plane where the screen of the electronic device lies in the three-dimensional display effect. Thus the display location and the display angle of the picture may be determined from the coordinate values of the picture on the x axis, the y axis and the z axis in the virtual three-dimensional coordinate system, and the angle α between the plane where the picture lies and the plane where the screen of the electronic device lies in the three-dimensional display effect.
In an embodiment of the present disclosure, the electronic device may display the respective pictures with a uniform size in a form of thumbnail.
In an embodiment of the present disclosure, the helical model may be applicable to an operating system of the electronic device and may be implemented through the following codes in the operating system of the electronic device:












  private int renderItem(GLCanvas canvas, ItemEntry entry,


  float interpolate, int pass,boolean paperActive) {


  canvas.save(GLCanvas.SAVE_FLAG_ALPHA


GLCanvas.SAVE_FLAG_MATRIX);


  Position position = entry.target;


  if (mPositions != null) {


  position = mTempPosition;


  position.set(entry.target);


  position.x −= mScrollX;


  position.y −= mScrollY;


  Position source = mPositions.getPosition(entry.item.getIdentity( ),


  position);


  source.x += mScrollX;


  source.y += mScrollY;


  position = mTempPosition;


  Position.interpolate(source, entry.target, position, interpolate);


  }


  canvas.multiplyAlpha(position.alpha);


  if (paperActive) {


  canvas.multiplyMatrix(mPaper.getTransform(position,  entry.base,


mScrollX, mScrollY), 0);


  } else


  {


  canvas.translate(position.x,position.y,position.z);


  int slotIndex=entry.index;


  final float r=200;


  float y=slotIndex*25f;


  float alpha=theta*slotIndex;


  float x=(float)(r*Math.cos(alpha/180*Math.PI));


  float z=(float)(r*Math.sin(alpha/180*Math.PI));


  float beta=alpha%360;


  if(beta<=180)


  beta=90-beta;


  else


  beta=270-beta;


  canvas.multiplyMatrix(mPaper.getTransform(x-position.x,y-


position.y,z-position.z,beta),0);


  }


  canvas.rotate(position.theta,0,0,1);


  int more=entry.item.render(canvas,pass);


  canvas.restore( );


  return more;


  }









It can be seen that, this segment of codes firstly defines the coordinate values x, y and z of the at least one picture respectively on the x axis, the y axis and the z axis in the pre-created virtual three-dimensional coordinate system, and then assigns x, y and z respectively, that is, the segment of codes substitutes the obtained at least one picture sequence number into the helical model, to obtain the coordinate values of the at least one picture on the x axis, the y axis and the z axis.
In an embodiment of the present disclosure, in the virtual three-dimensional coordinate system, the at least one picture is displayed by rendering the at least one picture, on the z axis in a direction, which is from being away from the screen of the electronic device to being proximate to the screen of the electronic device. Thus a previously rendered picture may be avoided from being shielded by a subsequently rendered picture, which would otherwise degrade the three-dimensional display effect of the pictures.
S204 is to obtain a movement instruction, and to move the at least one picture in the helical model indicated by the preset set of equations, according to the movement instruction.
In an embodiment of the present disclosure, the electronic device obtains the movement instruction from the sliding of a user's finger on the screen of the electronic device, herein the movement instruction may include a movement direction, a move speed and an attenuation period of time, herein the movement direction may be the direction in which the user's finger is sliding on the screen of the electronic device The movement speed may be the speed at which the user's finger is sliding on the screen of the electronic device while the finger is being moved on the screen of the electronic device, and the attenuation period of time may be determined from the speed at which the user's finger is sliding on the screen of the electronic device, and the attenuation period of time will be longer when the user's finger is sliding at a higher speed, and the attenuation period of time will be shorter when the user's finger is sliding at a lower speed.
In an embodiment of the present disclosure, when the at least one picture is displayed, the movement of the picture may be sped up, by sliding the user's finger on the screen of the electronic device, for example, the picture may move up and down along the central axis of the helical model at a speed becoming lower gradually until the picture is still. Optionally, this may be implemented through the following codes in the operating system of the electronic device:












  public boolean onFling(MotionEvent e1,MotionEvent e2, float


velocityX, float velocityY)


  {


  cancelDown( );


  int scrollLimit = mLayout.getScrollLimit( );


  if (scrollLimit == 0) return false;


  float velocity = WIDE ? velocityX : velocityY;


  mScroller.fling((int) -velocity, 0, scrollLimit);


  if (mUIListener != null) mUIListener.onUserInteractionBegin( );


  invalidate( );


  return true;


  }









In an embodiment of the present disclosure, when the at least one picture is displayed, the pictures may be magnified into view, by clicking on the pictures on the screen of the electronic device. In an embodiment of the present disclosure, the electronic device may display the respective pictures with a uniform size in a form of thumbnail.
Optionally this may be implemented through the following codes in the operating system of the electronic device:















public boolean onTouch(MotionEvent e)



{



cancelDown( );



if (mDownInScrolling) return true;



int index = mLayout.getSlotIndexByPosition(e.getX( ), e.getY( ));



if (index != INDEX_NONE) mListener.onSingleTapUp(index);
