Background
With the rapid development of the game industry, the complexity of the scenes is continuously increased while the games pursue pictures. With the change of the complexity of the scene, the object types and the object numbers of the scene are changed greatly.

First embodiment
The invention provides a method for determining position coordinates of particles, which is used for realizing irregular movement of the particles and simultaneously ensuring that the end point of the movement of the particles is unique. Referring to fig. 2, a flowchart of a method for determining position coordinates of particles according to the present invention is shown. The method for determining the position coordinates of the particles comprises the following steps:
s201, analyzing a preset scene file, and acquiring initial information of particles contained in the scene file.
Scene files may be referred to as background files, meaning files used in animation and movie production to store scene and background compositions. Scene files typically include no-motion or simple-motion objects such as buildings, mountains, trees, weather, and the like. For the purposes of the beauty and reality of the picture, particles are generally used for rendering the objects.
Thus, the initial information includes the emission position coordinates and the emission direction of the particles. It can be understood that the emission position coordinates are initial position coordinates of the particles; while the direction of emission determines the range of motion of the particles, i.e. in which quadrant of the cartesian three-dimensional coordinate system (left-hand coordinate system) the particles will move.
And S202, randomly generating first position coordinates of the particles by taking the emission direction as a reference.
Referring to fig. 2, a flowchart of a method for determining position coordinates of particles according to the present invention is shown. Wherein S202 includes:
s2021, randomly generating a first distance value, a second distance value and a third distance value.
The first distance value, the second distance value and the third distance value are distance values between the particles and the x axis, the y axis and the z axis respectively.
In an alternative embodiment, 3 values may be randomly generated using the rand function as distance values for the particle to 3 directions of the x, y, z axes; it will be appreciated that the distance values are positive numbers.
S2022, determining the sign of the particles in the x-axis, y-axis and z-axis according to the emission direction.
For example, the emission direction characterizes the particle movement in a first quadrant of a Cartesian three-dimensional coordinate system (left-hand coordinate system), the sign of the x-axis is "+", the sign of the y-axis is "+" and the sign of the z-axis is "-".
S2023 generates first position coordinates from the first distance value, the second distance value, the third distance value, and the sign of the particles in the x-axis, the y-axis, and the z-axis.
For example, a set of x=1, y=2, z=3 data is randomly generated, and the emission direction characterizes the particle movement in the first quadrant of a cartesian three-dimensional coordinate system (left-hand coordinate system), the sign of the x-axis is "+", the sign of the y-axis is "+" and the sign of the z-axis is "-". Thus, the coordinates of the particles are (1, 2, -3).
It will be appreciated that the first, second and third distance values generated by the random function are completely random, so that the first position coordinates generated are also completely random, i.e. the movement of the particles is also completely random.
S203, transforming the first position coordinate to obtain a second position coordinate.
With continued reference to fig. 3, S203 includes:
s2031, respectively judging whether the first distance value, the second distance value and the third distance value are odd or even, and executing S2032 if the first distance value, the second distance value and the third distance value are odd; if it is even, S2033 is executed.
It should be noted that the first distance value, the second distance value, and the third distance value may not be odd or even at the same time; but are each randomly odd or even, and when they are not both odd or even, different steps are performed, respectively.
For example, if the first distance value is an odd number and the second distance value is an even number, the step of S2032 may be performed on the first distance value and the step of S2033 may be performed on the second distance value.
S2032, generating a transformed first distance value, a transformed second distance value, and a transformed third distance value based on the first distance value, the second distance value, and the third distance value, and the first equation.
That is, if the first distance value, the second distance value, or the third distance value is an odd number, the transformed first distance value is generated based on the first distance value and the first expression, the transformed second distance value is generated based on the second distance value and the first expression, and the transformed third distance value is generated based on the third distance value and the first expression.
In an alternative embodiment, the first formula is: n is n i '＝3n i +1 (i=1, 2, 3); wherein n is 1 '、n 2 '、n 3 ' being the transformed first distance value, the transformed second distance value or the transformed third distance value, respectively, n 1 、n 2 、n 3 The first distance value, the second distance value or the third distance value respectively.
For example, if the first distance value n 1 =3, the transformed first distance value n 1 '＝3×3+1＝10。
S2033, generating a transformed first distance value, a transformed second distance value, and a transformed third distance value based on the first distance value, the second distance value, and the third distance value and the second equation.
If the first distance value, the second distance value or the third distance value is even, correspondingly generating a transformed first distance value based on the first distance value and the second expression, generating a transformed second distance value based on the second distance value and the second expression, and generating a transformed third distance value based on the third distance value and the second expression.
In an alternative embodiment, the second formula is: n is n i '＝n i 2 (i=1, 2, 3); wherein n is 1 '、n 2 '、n 3 ' being the transformed first distance value, the transformed second distance value or the transformed third distance value, respectively, n 1 、n 2 、n 3 The first distance value, the second distance value or the third distance value respectively.
For example, if the third distance value n 3 =10, the transformed third distance value n 3 '＝10÷2＝5。
S2034, generating a second position coordinate based on the transformed first distance value, the transformed second distance value, the transformed third distance value, and the sign of the particle in the x-axis, the y-axis, and the z-axis.
For example, a first distance value n 1 =10, second distance value n 2 =11, third distance value n 3 =12, the transformed first distance value n 1 ' =5, the transformed second distance value n 2 ' =34, the transformed third distance value n 3 ' =6; meanwhile, if the signs of the particles determined in step S2022 in the x-axis, the y-axis and the z-axis are "+", "-", respectively; the second position coordinates are (5, 34, -6).
S204, judging whether the second position coordinate is located in a range determined by taking the transmitting position coordinate as a sphere center and taking a preset threshold value as a radius, and if so, executing S205; if not, S206 is performed.
It should be noted that, the threshold value may be set according to the requirement of the user; when the second position coordinates lie within a range determined by taking the emission position coordinates as the sphere center and taking a preset threshold value as a radius, the particles are indicated to move to a position close to the initial position.
In connection with the example in S2034, if the threshold is 4 and the emission position coordinate is (1, 1), it is determined whether the second position coordinate is (5, 34, -6) or not within a range determined by taking (1, 1) as the center of sphere and taking 4 as the radius.
S205, the transmission position coordinates are taken as third position coordinates.
The third position coordinate is the next position coordinate of the particle in the motion process. That is, the third position coordinate is not the current actual position of the particle, but the position of the particle at the next time of coordinate conversion.
When the second position coordinates are located within a range determined by taking the emission position coordinates as sphere centers and taking a preset threshold value as a radius, the particle is indicated to be moved to be close to the emission position, so that the emission position coordinates are directly taken as third position coordinates, and the final position of the particle is the same as the initial position of the particle.
If the second position coordinate is located on the boundary of the sphere defined by taking the emission position coordinate as the center of the sphere and taking the preset threshold value as the radius, the emission position coordinate is also taken as the third position coordinate.
And S206, taking the second position coordinate as a third position coordinate.
When the second position coordinate is located outside the range determined by taking the emission position coordinate as the sphere center and taking the preset threshold value as the radius, the position where the particle is about to be located is further away from the emission position of the particle, and the particle can continue to move at the moment, so that the second position coordinate is taken as the third position coordinate.
S207, determining a transformation matrix of the particles based on the first position coordinates and the third position coordinates.
In practice, S203 to S206 predict the third position coordinates of the particles, and in the case of actual movement, it is necessary to perform position conversion of the particles by using the conversion matrix of the particles.
S208, performing position transformation on the particles according to the transformation matrix.
It should be noted that, the process of performing position transformation on the particles according to the transformation matrix is a process of moving the particles from the first position coordinates to the third position coordinates.
It should be noted that, for a particle having the emission position coordinates as the third position coordinates, the movement to the third position coordinates means that the particle has moved to the end point; in the case of particles having the second position coordinates as the third position coordinates, the third position coordinates need to be transformed again until the transformed third position coordinates are located within a range defined by taking the emission position coordinates as the sphere center and taking a preset threshold as the radius.
That is, the particles may continue to move randomly since they have not moved to the vicinity of the emission location at this time. The process of performing the irregular movement is continued as shown in S203 to S204 until the particles move to a range determined by taking the coordinates of the emission position as the sphere center and taking the preset threshold value as the radius.
For example, in combination with the distance in S204, since the third position coordinates (5, 34, -6) are located outside the range defined by taking (1, 1) as the center and taking 4 as the radius, it is necessary to perform the transformation operation on the third position coordinates (5, 34, -6) to obtain transformed third position coordinates (16, 17, -3), and determine again whether the transformed third position coordinates (16, 17, -3) are located within the range defined by taking (1, 1) as the center and taking 4 as the radius; and so on until the particle moves within a range determined by taking the emission position coordinates as sphere centers and taking a preset threshold value as a radius.
