Using the OpenTK library, I try to fill the field with dots evenly, but for some reason this simple thing fails.
At certain values, stripes appear - blank areas.
This is best seen in the screenshot:
I give the full code:
using System; using System.Drawing; using OpenTK; using OpenTK.Graphics; using OpenTK.Graphics.OpenGL; using OpenTK.Input; namespace testOpenTK { class Game : GameWindow { public Game() : base(900, 900, GraphicsMode.Default, "OpenTK Quick Start Sample") { VSync = VSyncMode.On; } protected override void OnLoad(EventArgs e) { base.OnLoad(e); GL.ClearColor(Color.White); GL.Enable(EnableCap.DepthTest); GL.MatrixMode(MatrixMode.Projection); GL.LoadIdentity(); GL.Ortho(0, Width, 0, Height, -1, 1); // Верхний левый угол имеет кооординаты(0, 0) GL.Viewport(0, 0, Width, Height); // Использовать всю поверхность GLControl под рисование } /// <summary> /// Called when it is time to setup the next frame. Add you game logic here. /// </summary> /// <param name="e">Contains timing information for framerate independent logic.</param> protected override void OnUpdateFrame(FrameEventArgs e) { base.OnUpdateFrame(e); if (Keyboard[Key.Escape]) Exit(); } /// <summary> /// Called when it is time to render the next frame. Add your rendering code here. /// </summary> /// <param name="e">Contains timing information.</param> protected override void OnRenderFrame(FrameEventArgs e) { base.OnRenderFrame(e); GL.Clear(ClearBufferMask.ColorBufferBit | ClearBufferMask.DepthBufferBit); GL.MatrixMode(MatrixMode.Modelview); GL.LoadIdentity(); GL.PointSize(1); GL.Begin(BeginMode.Points); for (int i = 0; i < Width; i++) { for (int j = 0; j < Height; j++) { GL.Color3(Color.Violet); GL.Vertex2(i, j); } } GL.End(); SwapBuffers(); } } class Program { [STAThread] private static void Main() { using (Game game = new Game()) { game.Run(30.0); } } } } Maybe someone knows what could be the source of the problem?
