Description
There is a stack of matrices for each of the matrix modes.
In
GL_MODELVIEW
mode,
the stack depth is at least 32.
In the other modes,
GL_COLOR
,
GL_PROJECTION
, and
GL_TEXTURE
,
the depth is at least 2.
The current matrix in any mode is the matrix on the top of the stack
for that mode.
glPushMatrix
pushes the current matrix stack down by one,
duplicating the current matrix.
That is,
after a
glPushMatrix
call,
the matrix on top of the stack is identical to the one below it.
glPopMatrix
pops the current matrix stack,
replacing the current matrix with the one below it on the stack.
Initially, each of the stacks contains one matrix, an identity matrix.
It is an error to push a full matrix stack
or to pop a matrix stack that contains only a single matrix.
In either case, the error flag is set
and no other change is made to GL state.
Errors
GL_STACK_OVERFLOW
is generated if
glPushMatrix
is called while
the current matrix stack is full.
GL_STACK_UNDERFLOW
is generated if
glPopMatrix
is called while
the current matrix stack contains only a single matrix.
GL_INVALID_OPERATION
is generated if
glPushMatrix
or
glPopMatrix
is executed between the execution of
glBegin
and the corresponding execution of
glEnd
.
