The ScreenRatioPixelCountLodStrategy class Implement a strategy which calculates LOD ratios based on coverage in screen ratios in the range [-1.0; 0.0] where -1.0 means the object is covering the whole screen and 0 covering almost nothing in the screen (very tiny). More...

Default constructor. | |
Real | getBaseValue () const override |
Get the value of the first (highest) level of detail. | |
