The Open Toolkit is an advanced, low-level C# library that wraps OpenGL, OpenCL and OpenAL.It is suitable for games, scientific applications and any other project that requires 3d graphics, audio or compute functionality. In short its called OpenTK
It is not enough to tell what is OpenTk by these definition. Those who addicted with dotnet framework for them it is like a dream to use all of the power of OpenGL and OpenAl . To create fastest game with OpenGL with power of C# its really a dream we just need to download some small size dll and add them in the project, not to take the tension of huge library of OpenGL.
It is not the fast C# implementation of OpenGL but it is the best. There are some previous like csgl , taoframwork etc. but they incomplete and bound by some limitation . And now they are completely unable to keep with dotnetframework.
Every OpenGL function we can call by GL class. like “glVertex2f(-2.0,-2.0) ” of opengl used in OpenTk as “GL.Vertex2(-2.0,-2.0)”
It has a very nice and flexible GUI options Cross-platform GLControl (Windows.Forms) which can easily add in visual studio toolbox , GLWidget which is another rich and useful componnent for (GTK#) and WPFControl classes. And there is also a Native, high-performance GameWindow which is designed specifically for games u can develop a game faster than u think.
It also has a very useful api collection like 3D math toolkit supplies Vector, Matrix, Quaternion and Bezier structs. Input API provides Keyboard, Mouse and Joystick interfaces. Display API for multiple monitors. OpenTK.Compatibility supports Tao framework applications.
And if u want to think about platform in dependency it supports 32- and 64-bit versions of Windows, Linux and Mac OS X. No need for mismanaged libraries – compile once, run everywhere. and the gr8 thing is you are free to use, modify and redistribute the source code. Suitable for open- and closed-source projects alike.
So for C# i m sure u cant find anything better than OpenTK to replace OpenGL. but if u want to develop really professional level game i have to tell u that u are not in right track. Cpp is far better than C# for that. And u direly want to do that in C# use direct x or XNA.
Thanks for reading it
