trochu viac nechapem tym velkostiam v OpenGL,

moj kod je tu:

		Gl.glClear(Gl.GL_COLOR_BUFFER_BIT);

            Gl.glLoadIdentity();

            Glu.gluLookAt(0, 0.0, 3.0, 0, 0, 0.0, 0, 1.0, 0);



		Gl.glPushMatrix();



                // translate the triangle

                Gl.glTranslated(0,0,0);



                // rotate the triangle

                Gl.glRotated(0, 0, 0, 1.0);



                // bind the texture we want to apply

                Gl.glBindTexture(Gl.GL_TEXTURE_2D, img.texture);



                // draw a quad with UV texture coords

                Gl.glBegin(Gl.GL_QUADS);

                    Gl.glTexCoord2f(0.0f, 1.0f);

                    Gl.glVertex2f( 0, 0);

                    Gl.glTexCoord2f(1.0f, 1.0f);

                    Gl.glVertex2f( 1, 0);

                    Gl.glTexCoord2f(1.0f, 0.0f);

                    Gl.glVertex2f( 1, 1);

                    Gl.glTexCoord2f(0.0f, 0.0f);

                    Gl.glVertex2f( 0, 1);

                Gl.glEnd();



            Gl.glPopMatrix();

			

			// Swap buffers

            Glfw.glfwSwapBuffers();

Už som to urobil ak by niekto chcel vedieť tak tu to má:

	static public void Draw_Img(int x, int y, Image image)

		{

			Console.WriteLine(x+" "+y+" "+image.height+" "+image.width);

			

			y = winheight - y;  // kôli tomu ze to pocita zdola

			

			Console.WriteLine(y);

			

			Gl.glPushMatrix();



                // translate the triangle

                Gl.glTranslated(0,0,0);



                // rotate the triangle

                Gl.glRotated(0, 0, 0, 1.0);



                // bind the texture we want to apply

                Gl.glBindTexture(Gl.GL_TEXTURE_2D, image.texture);



                // draw a quad with UV texture coords

                Gl.glBegin(Gl.GL_QUADS);

                    Gl.glTexCoord2f(0, 0);

                    Gl.glVertex2i( x, y);

                    Gl.glTexCoord2f(1f, 0);

                    Gl.glVertex2i( x + image.width, y);

                    Gl.glTexCoord2f(1f, 1f);

                    Gl.glVertex2i( x + image.width, y - image.height);

                    Gl.glTexCoord2f(0, 1f);

                    Gl.glVertex2i( x, y - image.height);

                Gl.glEnd();



            Gl.glPopMatrix();

		}



	static private void Reshape()

        {

            int width, height;



            // grab the window size

            Glfw.glfwGetWindowSize(out width, out height);

            if(height == 0 ) height = 1;



            // set perspective projection

            Gl.glMatrixMode(Gl.GL_PROJECTION);

            Gl.glLoadIdentity();

	}

		

	static public void DrawScreen(ILayout[] layout)

	{

		Reshape();

			

		// Clear color buffer

            Gl.glClear(Gl.GL_COLOR_BUFFER_BIT);

            Gl.glOrtho(0,winwidth,0,winheight,-1,1);

			

			

			// nakreslenie kazdeho layoutu

			for(int i = 0; i < layout.Length; i++)

			{

				if(layout[i].Active())

				{

					layout[i].Draw();

				}

			}

			

			// Swap buffers

            Glfw.glfwSwapBuffers();

		}
