使用OpenTK在C＃中绘制图形（x = y）？

Question

How to plot a simple graph (x=y) in C# using OpenTK ? both at Windws Form Application and at console App ?? What methods do use to plot that graph ?I'm new to this tool so aa good link or toutorial will help me a lot ....

Hey Carlos Oliveira,

Step 1: You should start with this link ( http://www.opentk.com/doc/chapter/0 )[1]

Step 2: For a simple x=y graph , copy-paste the code snippet provided in the link[1] and remove the game.RenderFrame part and replace with code snippet pasted just below

game.RenderFrame += (sender, e) =>

            {
                GL.Clear(ClearBufferMask.ColorBufferBit | ClearBufferMask.DepthBufferBit);

                GL.Begin(PrimitiveType.Lines);
                GL.Color3(Color.White);
                //YAxis
                GL.Vertex2(0.0f, 2.0f);
                GL.Vertex2(0.0f, -2.0f);

                //X-Axis
                GL.Vertex2(2.0f, 0.0f);
                GL.Vertex2(-2.0f, 0.0f);
                GL.End();

                GL.Begin(PrimitiveType.Points);
        // Plotting the Graph
                GL.Color3(Color.DeepSkyBlue);
                for(float i=0;i<2.0;i=(float) (i+0.001))
                {
                    GL.Vertex2(i,i);
                }
                GL.End();
                game.SwapBuffers();
            };

Thanks, Hope it helps

Also like Christos mentioned a simple search would have landed you on the initial chapters of openTK
