hiya, hope u can help me here

Code:

---

              glBegin(GL_TRIANGLE_STRIP);
                glVertex3f(0.0f, 0.0f, 0.0f);
                glVertex3f(0.1f, 0.0f, 0.0f);
               
                glVertex3f(0.0f, 0.0f, 0.1f);
                glVertex3f(0.1f, 0.0f, 0.1f);

                glVertex3f(0.0f, 0.0f, 0.2f);
                glVertex3f(0.1f, 0.0f, 0.2f);

                glVertex3f(0.0f, 0.0f, 0.3f);
                glVertex3f(0.1f, 0.0f, 0.3f);
        glEnd();

        glBegin(GL_TRIANGLE_STRIP);
                glVertex3f(0.1f, 0.0f, 0.0f);
                glVertex3f(0.2f, 0.0f, 0.0f);
               
                glVertex3f(0.1f, 0.0f, 0.1f);
                glVertex3f(0.2f, 0.0f, 0.1f);

                glVertex3f(0.1f, 0.0f, 0.2f);
                glVertex3f(0.2f, 0.0f, 0.2f);

                glVertex3f(0.1f, 0.0f, 0.3f);
                glVertex3f(0.2f, 0.0f, 0.3f);
        glEnd();

        glBegin(GL_TRIANGLE_STRIP);
                glVertex3f(0.2f, 0.0f, 0.0f);
                glVertex3f(0.3f, 0.0f, 0.0f);
               
                glVertex3f(0.2f, 0.0f, 0.1f);
                glVertex3f(0.3f, 0.0f, 0.1f);

                glVertex3f(0.2f, 0.0f, 0.2f);
                glVertex3f(0.3f, 0.0f, 0.2f);

                glVertex3f(0.2f, 0.0f, 0.3f);
                glVertex3f(0.3f, 0.0f, 0.3f);
        glEnd();

Ok now aht i need is something along the lines of two loops that run through the three blocks and voila it becomes shorter code:

OK heres what i made:

Code:

---

for (float loop_x = 0.0; loop_x < 0.3f; loop_x += 0.1f)
        {
                for (float loop_z = 0.0; loop_z < 0.4f; loop_z += 0.1f)
                {
                        glBegin(GL_TRIANGLE_STRIP);
                                glVertex3f(loop_x,        0.0f, loop_z);
                                glVertex3f(loop_x + 0.1f, 0.0f, loop_z);
                        glEnd();
                }
        }

---

OK it has to loop through the z and add 0.1 each time from 0.0 to 0.3, then it has to loop through on the x if u see.

Code:

---

        for (float loop_x = 0.0; loop_x < 0.3f; loop_x += 0.1f)
        {
                glBegin(GL_TRIANGLE_STRIP);
                        glVertex3f(loop_x, 0.0f, 0.0f);
                        glVertex3f(loop_x + 0.2f, 0.0f, 0.0f);
                       
                        glVertex3f(loop_x, 0.0f, 0.1f);
                        glVertex3f(loop_x + 0.2f, 0.0f, 0.1f);
       
                        glVertex3f(loop_x, 0.0f, 0.2f);
                        glVertex3f(loop_x + 0.2f, 0.0f, 0.2f);
       
                        glVertex3f(loop_x, 0.0f, 0.3f);
                        glVertex3f(loop_x + 0.2f, 0.0f, 0.3f);
                glEnd();
        }

The above code loops through the X ok for me but i need to add a second loop that does the z for me, though my 2n lot of code wont do it

Sorted ! - A few missplaced gl routines:

Code:

---

        for (float loop_x = 0.0f; loop_x < 0.3f; loop_x += 0.1f)
        {
                glBegin(GL_TRIANGLE_STRIP);

                        for (float loop_a = 0.0f; loop_a < 0.4f; loop_a += 0.1f)
                        {
                                glVertex3f(loop_x,        0.0f, loop_a);
                                glVertex3f(loop_x + 0.1f, 0.0f, loop_a);
                        }

                glEnd();
        }
