LOD in three.js (Merging meshes)

Question

I'm looking for a method, where I can use the LOD Object of three.js in a performant way ( http://threejs.org/examples/webgl_lod.html ).

My idea is to implement a LOD method, which is like this one in chapter 2.1 ( http://dl.acm.org/citation.cfm?id=364375 ).

There are 3 levels:

• a 3D model near the viewer
• a 2.5D volumetric texture in mid-range
• and a 2D texture in the distant

Now my questions are:

Is it posible to show a 2D texture as a level in the LOD object of three.js?

Can i merge lod objects in the distance? (Example: there are 10 meshes close to the camera, 2 group meshes in mid-range and one 2d texture in a distance far away)

Thanks for your help!

Answer 1

我认为从某种意义上说，这是可能的，因为您可以编写逻辑来完成所有操作..因此，我敢打赌，Three.js中的简单lod系统现在不提供这种功能，而是您可以在自己的lod系统中用/编写的功能三。
