collada 3D object mouse event


collada 3D object mouse event

should help you out coincidentally, i'm also working on a project requiring mouse events, and coded a small object to use.
code :
var mouse = {
    getIntersects: function( camera, sceneChildren, event ){
        event = event || window.event;

        var mouseX = ( event.clientX / window.innerWidth ) * 2 - 1;
        var mouseY = -( event.clientY / window.innerHeight ) * 2 + 1;

        var vector = new THREE.Vector3( mouseX, mouseY, camera.near );
            vector.unproject( camera );

        var raycaster = new THREE.Raycaster( camera.position, vector.sub( camera.position ).normalize() );

        var intersects = raycaster.intersectObjects( sceneChildren );

        if ( intersects.length > 0 ) {
            //console.log(intersects);
            return intersects;
        }
        return false;
    },

    Position3D: function(sceneChildren){
        var intersects = mouse.getIntersects( sceneChildren );
        return intersects[0].point
    }
}
document.addEventListener('click', function(event){
    var intersectObj = mouse.getIntersects( camera, scene.children, event)[0];
    if(window.console){ 
        console.log(intersectObj);
    }
    else{
        alert(intersectObj);
    }
});
var mesh = new THREE.Mesh(geometry, material);
    mesh.click = function(){
        alert('object was clicked');
    }

it fixes the issue The loading is occurring asynchronously. You are only showing a code fragment, but it looks like you can move the render() call to the last line of the colladaReady() callback function.

hope this fix your issue Assuming that dae_scene is a COLLADA scene returned from the ColladaLoader, here's what you can do to check for intersection:
code :
var toIntersect = [];
THREE.SceneUtils.traverseHierarchy(dae_scene, function (child) {
    if (child instanceof THREE.Mesh) {
        toIntersect.push(child);
    }
});
var ray = new THREE.Ray( camera.position,
                         vector.subSelf( camera.position ).normalize() );
var intersects = ray.intersectObjects( toIntersect );

This might help you You're not calling render() from your animate() function, so the scene is only rendered through the OrbitControls onChange event. Add render() at the end of animate() and it will work. You can also then remove the onChange callback, since you'll be rendering steadily.

I think the issue was by ths following , 5Qe,
Firstly, as per documentation from javascripture, relatedTarget is not related to click but for mouseenter, mouseleave, dragenter etc.
code :
string javascript = "document.getElementById('gobutton').addEventListener('mouseleave', function(event){alert(event.relatedTarget);});";

            ((IJavaScriptExecutor)driver).ExecuteScript(javascript);
