   openGL to openGLES
  Does anyone have any idea or examples of how to replace he following functions in an openGL app so that it can be used in openGLES?glTexGenfvglTexGeniglRasterPos3f

This probably will help you:Mathematics of glTexGenWhat are you using glRasterPos for? AFAIK you don't really need it for anything. Text rendering is probably the most likely use, but if GL ES is anything like OpenGL 3.0, then you'll just have to handle that yourself by using a character map texture and building a string with VBOs. If you're using it for something else and still confused then be more specific.;  Regarding the glTexGen calls, here is the source I am trying to convert:static const GLfloatplanex[]={1,0,0,0};static const GLfloatplaney[]={0,1,0,0};static const GLfloatplanez[]={0,0,1,0};glTexGenfv(GL_S,GL_OBJECT_PLANE,planex);glTexGenfv(GL_T,GL_OBJECT_PLANE,planez);glTexGeni(GL_S,GL_TEXTURE_GEN_MODE,GL_OBJECT_LINEAR);glTexGeni(GL_T,GL_TEXTURE_GEN_MODE,GL_OBJECT_LINEAR);glEnable(GL_TEXTURE_GEN_S);glEnable(GL_TEXTURE_GEN_T);glEnable(GL_TEXTURE_GEN_R);From what I can tell, it seems that I can use the coords for the planes as the tex coords and use glTexCoordPointer...would this be accurate?With regard to glRasterPos, it is for text rendering...I think I will just comment this out.   ;  What I don't get exactly...how do i get texture coordinates for a plane?
