NAME
glDepthMask - enable or disable writing into the depth buffer
C SPECIFICATION
void glDepthMask(GLboolean flag);
PARAMETERS
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()).
