这次我们用pixi.js 和arcgis js结合
我们先定义一下 传入数据结构 symbol 暂时不做
- let option = {
- renderer: {
- type: "simple",
- symbol: {
- }
- },
- data: [
- {
- geometry: [12956152.73135875, 4855356.473704897],
- attributes: {
- name: "北京"
- }
- },
- {
- geometry: [12697872.012783196, 2577456.5937789795],
- attributes: {
- name: "深圳"
- }
- }
- ]
- };
对于data 数据 ,
toScreen 方法参考链接提示
app 的构建参考 链接提示
- let data = this.options.data;
- for(let item of data){
- //转换屏幕坐标，获取颜色，半径和线条粗细样式
- let geo = item.geometry
- let XY1 = toScreen(geo);
- const geometry = new PIXI.Geometry()
- .addAttribute("position", [100, 100, -100, 100, -100, -100, 100, -100, 200, 200], 2)
- .addAttribute('uv', // the attribute name
- [0, 0, // u, v
- 1, 0, // u, v
- 1, 1,
- 0, 1], // u, v
- 2)
- .addIndex([0, 1, 2, 0, 2, 3]);
- const fragmentShader = `
- const float PI = 3.14159265359;
- uniform float iTime;
- uniform vec2 iResolution;
- varying vec2 vUv;
- float distanceTo(vec2 src, vec2 dst) {
- float dx = src.x - dst.x;
- float dy = src.y - dst.y;
- float dv = dx * dx + dy * dy;
- return sqrt(dv);
- }
- vec3 hsb2rgb( in vec3 c ){
- vec3 rgb = clamp(abs(mod(c.x*6.0+vec3(0.0,4.0,2.0),
- 6.0)-3.0)-1.0,
