Hey everyone Please can someone provide me with some assistance. I want to create a 3d cone in opengl using java (using lwjgl) So i can easily create 3d boxes using code like:
GL11.glPushMatrix();
        {        drawUnitCube(Colour.BLUE,Colour.BLUE,Colour.RED,Colour.RED,Colour.GREEN,Colour.GREEN);
        }
        GL11.glPopMatrix();


private void drawUnitCube(Colour near, Colour far, Colour left, Colour right, Colour top, Colour bottom)
    {
        
        Vertex v1 = new Vertex(-0.5f, -0.5f,  0.5f);
        Vertex v2 = new Vertex(-0.5f,  0.5f,  0.5f);
        Vertex v3 = new Vertex( 0.5f,  0.5f,  0.5f);
        Vertex v4 = new Vertex( 0.5f, -0.5f,  0.5f);
        Vertex v5 = new Vertex(-0.5f, -0.5f, -0.5f);
        Vertex v6 = new Vertex(-0.5f,  0.5f, -0.5f);
        Vertex v7 = new Vertex( 0.5f,  0.5f, -0.5f);
        Vertex v8 = new Vertex( 0.5f, -0.5f, -0.5f);

        // draw the near face:
        near.submit();
        GL11.glBegin(GL11.GL_POLYGON);
        { //3214
            v3.submit();
            v2.submit();
            v1.submit();
            v4.submit();
        }
        GL11.glEnd();

// draw rest of faces..etc..... 
But whats the equivalent for drawing a cone??? Anyhelp please
