This library simplifies the use of the openTK library by wrapping it into simple to use functions, perferct for C# and VB simple game development.

1. Add the library to your solution from Nuget.

1. Add a new .cs line to your console app, that will be your main place to code
   (Example bellow no. 1)
2. On your program.cs file add the example code no. 2,
3. If you dont want the console opening change your project properties to Windows Application

using System;
using OpenTK;
using OpenTK.Graphics;
using Program;

namespace yourNameSpace
{
    public class yourClass : MainRenderWindow
    {
        public Game(int width, int height, string title, double fps) : base(width, height, title, fps)
        {
        }

        protected override void OnLoad()
        {
            setClearColor(new Color4(0.0f, 0.0f, 0.0f, 1.0f)); //Sets Background Color
            UseDepthTest = false; //Enables Depth Testing for 3D
            UseAlpha = true; //Enables alpha use
            KeyboardAndMouseInput = false; //Enables keyboard and mouse input for 3D movement
            base.OnLoad();
        }

        protected override void OnRenderFrame(FrameEventArgs e)
        {
            Clear();

            DrawEllipse(500, 500, 10f, 10f, new Color4(1.0f, 1.0f, 1.0f, 1.0f)); //Draws a circle

            base.OnRenderFrame(e);
        }

        protected override void OnUpdateFrame(FrameEventArgs e)
        {
            base.OnUpdateFrame(e);
        }
    }

            //Run takes a double, which is how many frames per second it should strive to reach.
            //You can leave that out and it'll just update as fast as the hardware will allow it.
            game.Run();
        }
    }

• Boolean UseDepthTest (*Default = false*) => Specifies if rendering engine will use depth test (When depth test is true alpha will not work, if false rendering will work based on the which functions are called first),
• Boolean UseAlpha (*Default = true*) => Specifies if rendering engine will use alpha,
• Boolean KeyboardAndMouseInput (*Default = true*) => Specifies if rendering engine will use default keyboard and mouse input,
• Boolean showSet (*Default = false*) => Specifies if rendering engine open settings on esc,

• CreateMainLight(Vector3 pos, Color4 color) => Creates your main Light (static), make sure to run this function before any other 3D function but after Base.OnLoad(),
• CreateCube(Color4 Color) => Creates a 3D cube of the color you specify, returns a handle for making modifications to the cube,
• CreateSphere(Color4 Color) => Creates a 3D sphere of the color you specify, returns a handle for making modifications to the sphere,
• CreateTorus(Color4 Color) => Creates a 3D torus of the color you specify, returns a handle for making modifications to the torus,

• CreatePlane(float x1, float y1, float z1, float x2, float y2, float z2, float x3, float y3, float z3, float x4, float y4, float z4, Color4 color) => Creates a 3D plane of the color you specify, returns a handle for making modifications to the plane,
• OpenTexturedObj(string obj, string texture) => Opens .obj file with an attached .png texture, returns a handle for making modifications to the object,
• OpenObj(string obj, Color4 color) => Opens .obj file with no attached .png texture, returns a handle for making modifications to the object,
