Detailed Description

This Node manages the different levels of detail available for a Geometry and decides which one should be rendered, according to the distance from the current camera. The details of the selection process are taken from VRML97 standard.

The node chooses which child to render based on the range values in the Range multi-field and the current distance of the camera from the object. The children should be ordered from the highest level of detail to the lowest level of detail. The range values specify the distances at which to switch between the different children.

The center field is a translation offset in the local coordinate system that specified the center of the object for distance calculations. In order to calculate which level to display, first the distance is calculate from the viewpoint to the center point of the LOD node (which corresponding transformations). If the distance is less than the first range value, then the first LOD is drawn. If it is between the first and the second values, then the second LOD is drawn, and so on.

Example: Setting up a osg::DistanceLOD

Here is an example of setting up an lod core with a center and a range. You would also need to add children for the 4 LODs.

DistanceLOD lod = DistanceLOD::create();
beginEditCP(lod);
    // this is supposed to be the center of the LOD model,
    // that is, this is the point the distance is measured from
    lod->setCenter(12,1,5);
    // now we add the distances when models will change
    lod->getMFRange()->push_back(6.0);
    lod->getMFRange()->push_back(12.0);
    lod->getMFRange()->push_back(24.0);    
endEditCP(lod);
