Setting Up a Tessillation Shader

Hey all,
I am trying to make a tessilation shader from scratch. It shows “GL_TESS_CONTROL_SHADER was not declared in this scope” and “GL_TESS_CONTROL_SHADER was not declared in this scope”. Please let me know where I am wrong.

Thanks and Regards,

Then you will have to declare it yourself or update your header files.
If you are using glext.h, then get it from
https://www.opengl.org/registry/

If you are using some loader like GLEW, then download the latest version from their website.

Thanks a lot V-Man. It worked. I just updated the GLEW.

Regards,
