Internet Explorer 11 does not open local three.js,

问题:

That includes three.js examples too, while they do open online. I tried both python and node.js servers, it receives the file list, but when the HTML is clicked, the screen remains black. They open fine in Firefox, Chrome, SeaMonkey etc. Of course, it's IE 11 the problem, NOT three.js.

Any ideas how to make IE 11 open local three.js files?

回答1:

IE 11 started to run local three.js files directly (with drag and drop the HTML file) after I did the following:

Internet Options/Advanced/Security selected: "Allow active content to run in files on My Computer" and rebooted the computer.

But I found out that IE 11 has only partial WEBGL support, as it only supports WEBGL 0.94 instead of WEBGL 1.0 required for THREE.js.

Comparison:

Firefox 60

Chrome v67

IE 11.096

(According to online test https://browserleaks.com/webgl )

As a consequence, it won't run many three.js examples (and other implementations) whether locally or online. Here is a subset:

webgl_postprocessing_crossfade

webgl_buffergeometry_instancing_lambert

webgl_lines_fat

webaudio_sandbox

webaudio_timing

webaudio_visualizer

webgl_depth_texture - "NO SUPPORT"

webgl_geometry_minecraft

webgl_gpgpu_birds

webgl_interactive_cubes_gpu

webgl_kinect

webgl_loader_amf

webgl_loader_collada_kinematics

webgl_loader_draco

webgl_loader_gltf

webgl_loader_gltf_extensions
