glDepthMask

enable or disable writing into the depth buffer

Signature

glDepthMask( GLboolean ( flag ) )-> void
glDepthMask( flag )

Parameters

VariablesDescription
flag
Specifies whether the depth buffer is enabled for writing. If flag is GL_FALSE , depth buffer writing is disabled. Otherwise, it is enabled. Initially, depth buffer writing is enabled.

Description

glDepthMask specifies whether the depth buffer is enabled for writing. If flag is GL_FALSE , depth buffer writing is disabled. Otherwise, it is enabled. Initially, depth buffer writing is enabled.

Associated Gets

glGet with argument GL_DEPTH_WRITEMASK

Notes

Even if the depth buffer exists and the depth mask is non-zero, the depth buffer is not updated if the depth test is disabled. In order to unconditionally write to the depth buffer, the depth test should be enabled and set to GL_ALWAYS (see glDepthFunc ).
