私は球形の画像を3Dで作成しています(下図参照)。また、重なっている平面図(ラベル)を追加しました。 three.jsライブラリを使用してラベルをどのように分けることができますか? 2JavaScriptでラベルが重複しないようにするにはどうすればよいですか?
labelBox.prototype.update = function()
{
camera.updateMatrixWorld();
this.position.project(camera);
var screenvector = new THREE.Vector3();
screenvector.copy(this.position);
oldlabelpos.push(screenvector);
//this.position.normalize();
this.posx = Math.round((this.position.x + 1)* this.domElement.offsetWidth/2 + webglviewport.left);
this.posy = Math.round((1 - this.position.y)* this.domElement.offsetHeight/2);
var boundingRect = this.box.getBoundingClientRect(); //getBoundingClientRect() method returns the
//size of element (here it is box) and its position relative to viewport
//update the box overlays position
this.box.style.left = this.posx + 'px';
this.box.style.top = this.posy + 'px';
this.occludeLabel(this.box, this.marker);
};
labelBox.prototype.LabelUpdateFn = function()
{
//var labels =
のdocument.getElementById( 'MovingLabel1'); //のgetElementsByClassName( 'spritelabel'); //ラベル= $(ルート).find( ".spritelabel");
for(var k=0; k<oldlabelpos.length; k++)
{
this.reposition = new THREE.Vector3();
this.reposition = convertlatlonToVec3(oldlabelpos[k].x,
oldlabelpos[k].y).multiplyScalar(radius);
this.reposition.normalize();
camera.updateMatrixWorld();
this.reposition.unproject(camera);
this.newposx = Math.round((this.reposition.x + 1)*
this.domElement.offsetWidth/2 + webglviewport.left) - this.posx;
this.newposy = Math.round((1 - this.reposition.y)*
this.domElement.offsetHeight/2) - this.posy;
var boundingRect = this.box.getBoundingClientRect();
this.box.style.left = (this.newposx + boundingRect.width) + 'px';
this.box.style.top = this.newposy + 'px';
//$(this.box).css(left) =
this.occludeLabel(this.box, this.marker);
//var updatedpos = {updateposx, updateposy};
//newlabelpos.push(updatedpos);
}
}
