{{PageSyntax}}

  SUB _glClearDepth (BYVAL depth AS DOUBLE)
  void '''_glClearDepth'''(GLdouble {{Parameter|depth}});

  void '''_glClearDepthf'''(GLfloat {{Parameter|depth}});

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


{{PageDescription}}

'''_glClearDepth''' specifies the depth value used by {{KW|_glClear}} to clear the depth buffer. Values specified by '''_glClearDepth''' are clamped to the range [0, 1].


{{PageNotes}}

The type of the {{Parameter|depth}} parameter was changed from GLclampf to GLfloat for '''_glClearDepthf''' and from GLclampd to GLdouble for '''_glClearDepth'''. This change is transparent to user code.
