I converted the first example in Computer Graphics Using Open GL to C#, using the examples from the download as a template.
Here is the result:
using System;
using System.Drawing;
using System.Windows.Forms;
using CsGL.OpenGL;
public class DotsDemo : Form
{
MyView view = new MyView();
public DotsDemo()
{
Text = "Dots demo !";
view.Dock = DockStyle.Fill;
Controls.Add( view );
}
public static void Main()
{
DotsDemo di = new DotsDemo();
Application.Run( di );
}
}
class MyView : OpenGLControl
{
public override void glDraw()
{
GL.glClear( GL.GL_COLOR_BUFFER_BIT | GL.GL_DEPTH_BUFFER_BIT );
// Clear Screen And Depth Buffer
GL.glBegin( GL.GL_POINTS );
GL.glVertex2i( 100, 50 );
GL.glVertex2i( 100, 130 );
GL.glVertex2i( 150, 130 );
GL.glEnd();
GL.glFlush();
}
protected override void InitGLContext()
{
GL.glClearColor( 1.0f, 1.0f, 1.0f, 0.0f );
GL.glColor3f( 0.0f, 0.0f, 0.0f );
GL.glPointSize( 4.0f );
}
protected override void OnSizeChanged(EventArgs e)
{
base.OnSizeChanged(e);
GL.glMatrixMode(GL.GL_PROJECTION);
GL.glLoadIdentity();
GL.gluOrtho2D( 0.0, Size.Width, 0.0, Size.Height );
}
}
Be sure to add references to the OpenGL dlls: csgl-base, csgl-extensions, & csgl-opengl.
The program draws 3 dots in the lower left corner of the window.
