       glClearDepth are clamped to the range 0 1.

Name

       glClearDepth - specify the clear value for the depth buffer

Notes

       The type of the depth parameter was changed from GLclampf to GLfloat for glClearDepthf and from GLclampd
       to GLdouble for glClearDepth. This change is transparent to user code and is described in detail on the
       removedTypes() page.

Parameters

depth
           Specifies the depth value used when the depth buffer is cleared. The initial value is 1.
