#5037693 geometry shader to pixel shader

Posted by the dodger uk on 28 February 2013 - 01:06 PM

is there a way  to send a  int number or bool to the pixel shader from the geometry shader


i been writing a  geometry shader for grass , which expands  a point to a grass which has 4 quads which are all created on the geometry shader.


now  these all texture colour correctly . now  is there a way to send a  bool from the geometry shader to the pixel shader so that it will then texture sample from a  picture of a flower, 


so that the grass can either be  grass or  grass with a flower head at the end of it
