gl_FragCoord.z question(s)

What coord system is gl_FragCoord in? If I read this value in my frag shader, what range of values can I expect? Is it clamped to [0,1]?


if I’m not mistaken, gl_FragCoord is in Normalized Device Coordinates (NDC), which in OpenGL means x, y, and z are between -1 and +1.

here’s a good reference explaining the different coordinate systems:
