Port of the OGLdev Modern OpenGL Tutorials examples from C++ to C#, featuring Silk.NET
Notes:
I've done as much as possible to keep the OpenGL code 1:1 with OGLdev's C++, but there's a couple things that are definitely different.
-
VAOs: The original Tutorials don't use a VAO until Tutorial10, instead opting to depend on GLUT-Weirdness. As Silk.NET does not expose this functionallity and it is also not good OpenGL-Practice I use a VAO in these episodes, but explain it in more detail when apropriate.

-
Windowing: I elected to use Silk.NET's SDL bindings for windowing rather than GLUT simply because Silk.NET doesn't have bindings to GLUT, and SDL is what Silk.NET's own examples use.
-
Program Structure: Silk.NET's window management is structured differently from GLUT's, making use of event handlers like
OnLoad(). For the overall structure of each program I used the same approach as Silk.NET's examples.
Other things were kepts exactly the same.
-
Naming Conventions: When it comes to naming variables and functions I chose to copy OGLdev's naming conventions as closely as possible, which means the code is a little ugly by C# standards.
-
Shaders: GLSL works the same whether you're using C++ or C#, so the shaders are 100% copy-pasted from OGLdev's example code with no changes at all.
