If I have a shaded object…and lines around (not on) this object, how would I use the depth test features in openGL to show the lines behind the object, but make them dashed instead?
Can you give a code example of how the depth test stuff goes? Thanks!
Maybe you should render lines two times - solid with glDepthFunc(GL_LEQUAL)and dashed with glDepthFunc(GL_GREATER) and render them after shaded object.
