public static
     
     
bool renderCellSubset( FrameContext & context,
  cell_ptr cell,
  uint32_t budgetBegin,
  uint32_t budgetEnd
)    

Display a given subset of the potentially visible objects inside the given cell.

Parameters

context
Context that is used for rendering.
cell
Cell to retrieve the potentially visible set from.
budgetBegin
Number of triangles where the rendering of objects should start. If zero then the rendering starts at the beginning.
budgetEnd
Number of triangles where the rendering of objects should stop. If zero then the rendering is not stopped.

Returns

trueif the objects were display andfalseif an error occurred.
