HI there, how do you do wireframes in openGL. I need a wireframe for 3d cube and triangle. The lines need to be 2 pixels wide. Can you help please… i am useing glut.
thanx in advance
To fo the wireframe part you need to call the glPolygonMode function. To do change the linewidth you need to call glLineWidth. Here is the code:
glPolygonMode(GL_FRONT_AND_BACK, GL_LINE);
glLineWidth(2.0);
Remember that these functions only need to be called once, so put them in your init function.
