That was quick!

It loads fairly quickly on my 10 year old dev box. The skyline (heh) can be made brightened by setting the color of the renderer:

scene.background = new THREE.Color(0x6D6D6D);

Testing on models with stickers show that debth testing can fail, so the camera parameters (far, near, FOV, etc.) might have to be tuned so they work on all models.

Once I iron out the kinks, we'll be able to test on the entire omr catalog and tweak as needed.

It kind of looks like both parts have the same amount of travel in one dimension, but the 1x3 has much less travel in the other dimension, leading to both the discontinuity in the specular between the two parts, and the much more pronounced slope of the reflection in the 1x3 part.
Is this a reflection from a point light or a directional light? A directional light can explain it since it does not pay attention to the parts in comparison to the light source.

On the other hand. You can also see similar effects with point lights since I reuse textures on the parts (it is expensive to generate textures, so reusing them is good for performance).

My best guess is that you are seeing a directional light here. You can press LEFT/RIGHT to toggle between the lights and use DELETE to remove them. Button controls are on their way, but I am focusing on setting up the renderer first as Orion is progressing much faster than I dared hope.

We're in business.

Here's a sample model page (with brigl):

To see a model rendered with LDBI simply add "_ldbi" after "files":

Note: this a preview. There are quite a few tweaks to be made

Doesn't handle texmap images.

Or is it that one of the tweaks?

No. Texmap support is a known limitation.
Support TEXMAP language extension #13

But neither does brigl.

I did, however find a bug that prevented the display of that model. This is now fixed.

So one clear advantage of LDBI is that I can load huge models on my iPhone. Brigl crashes when I load the UCS Imperial Star Destroyer and LDBI does not.

The UCS Falcon crashes the tab on my desktop when brigl is used. With LDBI, time to render is reasonable and it doesn't crash the tab.

Yes, works great, especially considering the size of the model. As it nonetheless takes some time to load (about 30 seconds here), would it be possible to get some form of progress bar?
Otherwise, got a display problem, the feet of the Falcon sometimes disappear:
