Aframe 在帧中添加指向GLTF对象的链接

是否可以添加指向GLTF 3d对象的链接（使用标记触发）

我已经尝试了通常的“a-link”方法，onClick方法，甚至应用了一个id和使用jQuery——都没有运气——任何帮助都将不胜感激

<a-scene embedded arjs>
  <a-marker id="dragon" preset="custom" type="pattern" url="pattern-dragonfly.patt">
    <a-entity animation-mixer="clip: *;" scale="1.5 1.5 1.5" gltf-model-next="src: url(dragon.gltf);"></a-entity>
  </a-marker>

  <a-entity camera></a-entity>
</a-scene>

要实现此功能，您需要为gltf创建一个带有光线投射器的光标和一个自定义组件

 <a-entity id="mouseCursor" cursor="rayOrigin: mouse" raycaster="objects: .clickable"></a-entity>
 <a-entity id="tree" gltf-model="#gltftree" scale="5 5 5" treeman class="clickable"  ></a-entity>

然后创建事件监听器来检测相交事件，并保存已相交的对象，并高亮显示它，以便用户知道它是活动的，如下所示

 init: function(){
                let el = this.el;
                let self = this;
                self.trees = [];              
                el.addEventListener("model-loaded", e =>{
                    let tree3D = el.getObject3D('mesh');
                    if (!tree3D){return;}    
                  console.log('tree3D', tree3D);
                    tree3D.traverse(function(node){
                        if (node.isMesh){   
                          console.log(node);
                          self.trees.push(node);                          
                          node.material = new THREE.MeshStandardMaterial({color: 0x33aa00});
                        }
                    });
              });

el.addEventListener('raycaster-intersected', e =>{  
                self.raycaster = e.detail.el;
                let intersection = self.raycaster.components.raycaster.getIntersection(el);
                  console.log('click', intersection.object.name, self.mouseOverObject, 
                            intersection.object.name != self.mouseOverObject );  
                if (self.mouseOverObject != intersection.object.name){
                  intersection.object.material.emissive = new THREE.Color(0xFFFF00);
                  intersection.object.material.emissiveIntensity = 0.5; 
                } else {
                   intersection.object.material.emissive = new THREE.Color(0x000000);
                  intersection.object.material.emissiveIntensity = 0.0; 
                }                  
                  self.mouseOverObject = intersection.object.name;
              });

               el.addEventListener('raycaster-intersected-cleared', e =>{  
                self.trees.forEach(function(tree){
                   tree.material.emissive = new THREE.Color(0x000000);
                  tree.material.emissiveIntensity = 0.0; 
                });    
                  self.mouseOverObject = null;
              });

  el.addEventListener('click', function(){
                console.log(self.mouseOverObject);
                if(self.mouseOverObject === "Trunk_A"){
                  console.log('link');
                  let url = 'https://supermedium.com/supercraft/';
                  let win = window.open(url, '_blank');
                  win.focus();
                }
              });

最后添加一个点击监听器来操作超链接，如下所示

 init: function(){
                let el = this.el;
                let self = this;
                self.trees = [];              
                el.addEventListener("model-loaded", e =>{
                    let tree3D = el.getObject3D('mesh');
                    if (!tree3D){return;}    
                  console.log('tree3D', tree3D);
                    tree3D.traverse(function(node){
                        if (node.isMesh){   
                          console.log(node);
                          self.trees.push(node);                          
                          node.material = new THREE.MeshStandardMaterial({color: 0x33aa00});
                        }
                    });
              });

el.addEventListener('raycaster-intersected', e =>{  
                self.raycaster = e.detail.el;
                let intersection = self.raycaster.components.raycaster.getIntersection(el);
                  console.log('click', intersection.object.name, self.mouseOverObject, 
                            intersection.object.name != self.mouseOverObject );  
                if (self.mouseOverObject != intersection.object.name){
                  intersection.object.material.emissive = new THREE.Color(0xFFFF00);
                  intersection.object.material.emissiveIntensity = 0.5; 
                } else {
                   intersection.object.material.emissive = new THREE.Color(0x000000);
                  intersection.object.material.emissiveIntensity = 0.0; 
                }                  
                  self.mouseOverObject = intersection.object.name;
              });

               el.addEventListener('raycaster-intersected-cleared', e =>{  
                self.trees.forEach(function(tree){
                   tree.material.emissive = new THREE.Color(0x000000);
                  tree.material.emissiveIntensity = 0.0; 
                });    
                  self.mouseOverObject = null;
              });

  el.addEventListener('click', function(){
                console.log(self.mouseOverObject);
                if(self.mouseOverObject === "Trunk_A"){
                  console.log('link');
                  let url = 'https://supermedium.com/supercraft/';
                  let win = window.open(url, '_blank');
                  win.focus();
                }
              });

单击中继线以激活超链接。

下一个gltf型号是什么？为什么不使用？当然可以将gltf模型转换为链接。它包括添加一个raycaster系统，创建一个自定义组件，该组件遍历gltf模型以查找与raycaster返回的内容匹配的内容，然后调用执行链接的函数，该函数可能会打开一个新的web浏览器选项卡。也许对你来说，准确地描述你想要发生的事情是有意义的。@Diego gltf模型下一步不需要单独的a-assets@Thomas，谢谢-基本上，当用户触摸3D对象时，我希望他们被带到一个网站上-有没有你建议的工作示例？谢谢！（对延迟回复表示歉意）
