  6. //! Grid scene node
  7. /*! If you need a grid on the XY or ZY axis, simply rotate this node by 90
  8. degrees in the appropiate axis.
  9. This node creates an XZ grid by default, which should be fine for normal use.
  10. Axis Lines are a default Red and Blue for the X and Z axis respectively.
  11.  
  12. Please note that the internal meshbuffer used for the grid has a max size of 65535 indices.
  13.  
  14. Thanks goes to MasterGod for helping to clean up the code and for a few bug fixes.
  15.  
  16. Additional thanks to:
  17. JP for optimising the rendering.
  18. Vins for fixing a nasty crash bug and optimising memory usage.
