Please update your graphic card drivers if you have any issues and make sure you are running on the correct graphics card and not the integrated one.įirst off lets define a struct to hold our vertex position and color. Initialize a buffer Some of the methods used here require OpenGL 4.5.0 to work. This part will build upon the game window and shaders from the previous post. If you think that the progress is slow, then know that I am a slow learner :P I write these posts as a way to learn and if someone else finds these posts useful then all the better :) OpenGL 4 with OpenTK in C# Part 15: Object picking by mouseĪs stated in the previous post, I am in no way an expert in OpenGL.

In this post we will look at how to access buffers in OpenGL from your application code to provide your shaders with vertex data and to draw our first triangle.
