   ObjectSelection in iPhone
  Hi,greetings to all.My development platform is iPhone and I am kind of new in the field of OpenGL.I am trying to select which the user touches.I am using this technique.http://gpwiki.org/index.php/OpenGL_Selection_Using_Unique_Color_IDsEverything is fine (theoretically).But How can I render only in the color buffer.Any help regarding this will be highly appreciated.   
  Hi!By "But How can I render only in the color buffer." I think you mean how to not write in the depth buffer? it's easy:glDepthMask(GL_FALSE);don't forget to enable it again when you need it glDepthMask(GL_TRUE)   ;  Yeap . . . as there are 2 bufers only.Thanks,
