glClearDepth.3G man page

glClearDepth — specify the clear value for the depth buffer

C Specification

void glClearDepth(GLdouble depth);

void glClearDepthf(GLfloat depth);



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


glClearDepth specifies the depth value used by glClear() to clear the depth buffer. Values specified by glClearDepth are clamped to the range 0 1.


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.
