Hy,
how i can setup a spot light in opengl?
the code changes on the different versions of opengl?
How i know what type of opengl i’m use?
thanks.
To query version of OpenGL on linux type
glxinfo | grep "OpenGL version"
on Windows there are number of programs which can do that, for example OpenGL Extension Viewer (GLView or sth. like that)
