glEnd(); problem in glcolor after texturing.. help!!!
Author
hello...
i've been experiencing a problem in nehe lesson 7. if u add this code in the program. it will display a red texturing (because of the axes color).
what i wanna do is to display a nice texturing quad (the texture file is brown) and below it is a nice x and z axes (in red). but it just display ALL of it in red including the texturing quad although it's initial texture is brown. how to solve this?

first of all , my gueses are that you are confusing texture mapping with coloring ,hence the lack of glBindTexture(); ? ,anyway if still going for texture mapping check if you glEnable(GL_TEXTURE_2D); and draw the quads with glBegin(GL_QUADS); if not you can change the color of the quad with another glColor before the glBegin(GL_QUADS);

i''m not confusing texture mapping with coloring. i just wanna make a nice x and z axes beneath it (the quad texturing)and in red color. i''ve enable glEnable(GL_TEXTURE_2D); in the InitGL function. also draw the quads with glBegin(GL_QUADS).
