xeometry is an open source (MIT) JavaScript library from @xeographics for viewing and interacting with 3D glTF models on WebGL.
Use it to build 3D viewer apps and custom interactive presentations of glTF content, or as a boilerplate to bootstrap the development of your own 3D viewer.
var viewer = new xeometry.Viewer({ canvasId: "theCanvas" });
viewer.loadModel("saw", "models/Reciprocating_Saw.gltf", function () {
viewer.setOpacity(["saw#0", "saw#1", "saw#2", "saw#3", "saw#11"], 0.3);
viewer.viewFit("saw");
});[ Run this example ]
