However, in the prior art, a dynamic visual query reminding state cannot be vividly displayed in the regional query service, and the user cannot be fed back obviously and intuitively.

In particular implementation, as shown in fig. 1, the method comprises the steps of:
step S100, acquiring parameter attributes corresponding to the target scanning effect, and determining the particle number for simulating the scanning effect according to the parameter attributes.
Specifically, the present embodiment first selects mapbox gl. Js and three. Js as development tools.
Both mapbox gl. Js and three. Js are world-level open source graphics engines. mapbox gl. Js is a map open source engine in the webgis domain, used as a geographic communications system. the thread. Js is a web-end general engine, has rich community development components and accumulation, and is highly abstract and graphical drawing and rich interface expansion. The embodiment can build the webgis system in the shortest time by adopting the open source technology, and has quite maturity and expansibility. The mapbox gl.

Js support the development of a graphics bottom layer interface webgl, the parallel rendering strength calculation of the GPU (graphics accelerator) can be called by utilizing the pipeline programming of the webgl to simulate a vivid water body simulation special effect, so that a webgis system built by the mapbox gl. Js has the capability of being directly connected with the bottom layer, and the GPU (graphics accelerator) is utilized to render the high-efficiency stable special effect.
Since the following features need to be satisfied when simulating the radar scanning effect: 1. the dynamics, i.e. the final effect, is to be scannable for rotation as shown in military radar monitoring equipment. 2. The effect of regularity, i.e. movement, is to assume a sector like that shown in military radar monitoring equipment. 3. The tail flame effect, namely the effect that the front density of the movement direction is high and the tail density is low is presented while the dynamic performance and the regularity are provided, and the physical law of operation of the military radar monitoring equipment is simulated. 4. The periodicity, i.e. the scanning effect, is repeated. Thus, several requirements for achieving an analog radar scanning effect are well defined, as well as a substantially complete reference effect.
Having clarified three requirements and general effects of achieving the analog radar scanning effect, the present embodiment also needs to clarify how these features and effects are achieved with a program, and the present embodiment considers how the following characteristics are achieved with a program.
Characteristic 1 is to realize a scanning area with dynamics. There are two conceivable solutions, the first being to directly draw a polygon and rotate it around the center of the circle. However, the practice proves that the tail flame effect is difficult to achieve, the effect cannot be expected, and the tail flame effect is abandoned. The second approach is to use particles of some kind of motion to make up the whole dynamic scanning area, controlling the movement by controlling the motion and transparency of the particles.
Property 2 is a requirement for realizing a polygon with property 1, requiring that it must assume a fan-shaped pose. Algorithms may be used to fan the moving particles.
Characteristic 3 is a requirement for the effect of the movement, i.e. it must be high density directly in front of the direction of movement, high brightness and low density behind the direction of movement, with a slightly dull color. It is necessary to calculate the transparency of the particles and set them up according to the relation between the moving parts and time during the process of controlling the movement of the particles.
Characteristic 4 is the result of requiring the movement to be repeated without stopping, the whole movement process must be recorded using an algorithm and reset at the right moment so that it can be run cyclically.
The present embodiment selects a particle system as a tool to simulate the radar scanning effect. The particle system is a high-performance simulation method commonly used in computer graphics, and the principle is that the described object is abstracted into point particles in the computer graphics, and then the particles are subjected to operations such as movement, color change, size change and the like according to a certain rule by adopting a space mathematical method, so that the movement characteristics of the object are simulated. The design method converts the simulation radar scanning effect into control of a particle system by using the thought of programming, and simulates the radar scanning effect by controlling the spatial distribution, the motion rule and the size of the particle system, so that the basis is made for the realization of an actual program very clearly.
In order to simulate the radar scanning effect, the embodiment quantifies the object characteristics of the radar scanning effect for program call to develop a particle system. Specifically, the embodiment obtains a parameter attribute corresponding to the target scan, where the parameter attribute includes: the center position (center) of the radar scanning effect, the color (color) of the radar scanning effect, the radius (radius) of the radar scanning effect, the fan angle (length) of the radar scanning effect, the sense of thickness (width) of the radar scanning effect, and the speed of movement (speed) of the radar scanning effect.
The steps are as follows: s200, according to the particle number, acquiring the coordinate position of each particle.
The scheme of the embodiment is to simulate the radar scanning effect by adopting a plurality of circles with small to large radiuses and formed by particles. The circle has radius and center attributes, the color and thickness of the particles can be adjusted, the fan-shaped included angle (length) parameter of the input analog radar effect is increased, the circle is just a plane circle, the circle formed by the particles is in a coloring device program, and the effect of the particles moving along the circle can be realized by adopting a method of controlling the sequence of the particles. The specific implementation is as follows:
based on the center position (center) of the radar scan and the radius (radius) of the radar scan, we can calculate the coordinates of the whole circle by classical mathematical circle algorithm (knowing the coordinates of the center and the coordinates of any point on the radius calculation circle), and setting the particles according to these coordinates will present a circle (it is necessary to increase the calculation density in the algorithm, and it appears that the arrangement of a plurality of particles forms a circle). The total number of particles constituting the loop is then known by classical mathematical round algorithm, the position of each particle is calculated in a particle-by-particle manner in the shader program, and the same serial number (1, 2, 3..total number of particles) as the total number of particles is input into the shader program, so that the shader program can know which serial number of particles the program is handling by reading this serial number when calculating the position particle-by-particle.
And step 300, controlling the particles to present radar scanning effect through a shader program according to the coordinate position of each particle.
In specific implementation, the embodiment inputs a time parameter into the shader; and then controlling the particles to present radar scanning effect according to the time parameter. Specifically, in this embodiment, a particle serial number is obtained, and the particle serial number is compared with the time parameter and a fan-shaped included angle corresponding to the target scanning effect; and if the particle serial number is smaller than the sum of the fan-shaped included angles corresponding to the time parameter and the target scanning effect and the particle serial number is larger than the time parameter, controlling the particles corresponding to the particle serial number to be visible so that the particles show the radar scanning effect. In addition, only a small part of the control length of the whole circular ring (namely the sector included angle length of the radar effect) can be pushed forward along with the increase of time, so that the circular ring has the dynamic property and the tail flame effect, and the circular ring has the characteristic 1 dynamic property and the characteristic 3 tail flame effect. As particularly shown in fig. 2.
If the distance from the center of the circle to the maximum radius (radius) is divided into n segments, each segment being a radius of a new circle, then generating n circles according to the same center of the circle (the circles differ only in different radii) moving together will create an effect that approximates a sector of a field moving forward, i.e. a sector effect, meeting the sector requirement of feature 2, as shown in particular in fig. 3. And different sector patterns can be obtained along with setting different sector angles length. Finally, based on the animation effect principle in the shader program, the radar scanning animation is controlled by controlling the relation between the time, the fixed point coordinate sequence number and the fan-shaped included angle length of the radar effect, when the time is increased to be the same as the total number of particles, the completion of one-round animation is proved, at the moment, the time program is required to be set to be 0, and a section of new scanning animation is restarted to finish the periodicity of the characteristic 4 if the new addition is continued. The embodiment uses a plurality of circles formed by particles, realizes the simulation radar scanning effect in a mode of setting different attributes and rules by an actual program, and meets the four characteristics.
To sum up, in this embodiment, first, a parameter attribute corresponding to a target scanning effect is obtained, and the number of particles for simulating the scanning effect is determined according to the parameter attribute; according to the particle quantity, acquiring the coordinate position of each particle; and controlling the particles to present radar scanning effect through a shader program according to the coordinate position of each particle. The embodiment is beneficial to realizing the visualization of the radar scanning effect, and the reminding state of dynamic visual inquiry can be vividly displayed in the regional inquiry service of the smart city, so that the user is more intuitively fed back.
