javascript - Show/Hide models in JSC3D -



javascript - Show/Hide models in JSC3D -

i have jsc3d scene contains multiple files. goal show/hide 1 of models onclick call. 2 options can come recreate scene 1 model missing, or somehow access visible property of 1 of models. i've tried various permutations of alert code access visible property, no luck there. updateview function effort recreate scene missing model. btw, if alter colors[newloaded] colors[newloaded+1] colors update, displayed models remain same. has been many years since looked stuff sure easy missing thanks

1) add together <div> within <body> tag "objectlist".

<div id="objectlist"></div>

2) after lastly viewer.update(); add together little code

viewer.onloadingcomplete = function() { var shtml =""; for(obj in viewer.scene.children) { shtml+="<input type='checkbox' value='" + obj + "' checked onclick='setobject(this);'/>" + viewer.scene.children[object] + "<br />"; var objects = document.getelementbyid(objectlist); objects.innerhtml = shtml; };

3) add together setobject() function.

function setobject(self) { viewer.scene.children[self.value].visible = self.checked; }

except point #1 should in javascript code.

that's it...

enjoy , in case issues allow me know @ sarillaprasad@yahoo.com [or] post here :d
