SharpGLES

OpenGL ES 2.0 for .NET Desktop

Use via nuget:

PM> Install-Package SharpGLES

The are examples in the Examples folder.

To use in Windows Forms:

using System;
using System.Windows.Forms;
using SharpGLES;

public partial class GLESForm : Form
{
	private EGLDisplay _display;

	public GLESForm()
	{
		SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint, true);
	}

	protected override void OnPaintBackground(PaintEventArgs e)
	{

	}

	protected override void OnPaint(PaintEventArgs e)
	{
		Draw();

		_display.SwapBuffers();

		Invalidate();
	}

	private void Draw()
	{
		GLES20.Viewport(0, 0, Width, Height);

		GLES20.ClearColor(0f, 0f, 0f, 0f);
		GLES20.Clear(GLES20.GL_COLOR_BUFFER_BIT);

		//draw away...
	}

	protected override void OnHandleDestroyed(EventArgs e)
	{
		_display.Dispose();

		base.OnHandleDestroyed(e);
	}

	protected override void OnHandleCreated(EventArgs e)
	{
		base.OnHandleCreated(e);

		_display = new EGLDisplay(Handle);
	}
}

The GLBuffer class can be used to send data to the likes of GLES20.BufferData etc as it provides an implicit cast to IntPtr and uses an internally pinned array.

To load a .NET image as a texture use the GLUtils.TexImage2D method.
