how to do zoom in and out in orthographic projection? As I zoom in the detailed geometry should be loaded .
LOD is calculated based on the distance from the eye to the object. So if you move the camera a different LOD level will be selected.
But as you've probably discovered dollying the camera does not zoom in ortho. I don't think there's a simple solution; you could try [moving the camera or play with the LOD bias (to affect LOD)] and scale the object (or the viewport) to change the scenes size.
