overridevirtual

Find the nearest intersection from a point (x,y,z) along a vector(vx,vy,vz) stored in a collision point (cx,cy,cz) with normal (normal_x, normal_y, normal_z)

Return values

false if no intersection was found (and the intersectionResult is NOT set). Starts the intersection search from intersectionRoot(s).

Will not intersect with excludeNode. Will constrain the Isector used to the specified length if > 0.0 The useHighLod argument tells the intersector that if the terrain is an osgEarth terrain, don't settle for whatever is paged in; get the highest LOD from the map server for this location and use that Note that if maxIsectorLength is not set, the default is the diameter of the database, which for large (and especially geocentric) databases and world databases, may be too large to get adequate precision when trying to interect small (high resolution) triangles. It is recommended that you set the isector length to something more specific if possible, like the altitude of the observer + a constant, for example; or, for osgEarth databases, useHighLod=true, which will also eliminate the problem.
