Say Goodbye to GLSL Hacker and Welcome Back GeeXLab
GLSL Hacker is a project I started about 3 years ago with a first public version released on January 2013.
How to Check the Availability of an OpenGL Extension
It may be useful to know if the current OpenGL implementation supports a particular OpenGL extension. For example you have coded a cool OpenGL 4.0 demo based on tessellation shaders. It would be nice to display a different scene (actually an error scene) if the demo runs on a system that is limited to OpenGL 3.0.
How to Check OpenGL Errors
I didn’t checked all possible use cases of GLSL Hacker (a huge and actually impossible task) and some sequences of drawing instructions (render calls) can generate OpenGL errors. So if you suspect something dodgy because the rendering is not what you expect, you can check the OpenGL errors after some particular instructions.
GL-Z 0.1.0: Some Coding Details
GL-Z has just been released on Geeks3D’s main blog. It’s a simple OpenGL tool that displays GL_VERSION, GL_RENDERER as well as extensions list.
