potree for meshes? about potree

Simplifying meshes and point clouds are very different tasks. For now, I want to concentrate on the later.

However, there are already some possible solutions to your problem:

• three.js has a LOD object that will display different meshes, depending on the distance to the camera. You could create different resolutions of your object (3D packages like 3ds max can do this), then load the low resolution mesh and display it. In the mean time, you start loading the next higher resolution model and add it to the LOD object once it's been loaded. Here is an example of three.js LOD: webgl lod
• Rendering terrain, like in google earth, is yet another problem for which I haven't found a ready to use solution, just a realy nice demo: http://www.zephyrosanemos.com/windstorm/current/live-demo.html

If it's just about clicking on a surface, it is also possible to raycast point clouds:

Would Harvest4D's Floating Scale Surface Reconstruction be an integratable solution?
