Returns the current transformation matrix.
FORTRAN (libfgl.a)
void getmatrix(Matrix matrix)
SUBROUTINE GETMAT(matrix) REAL matrix(4,4)
The getmatrix subroutine copies the matrix from the top of the stack to a user-specified array. This routine does not alter the matrix stack. When the system is in projection matrix mode, the matrix stack is not accessible. In projection mode, the matrix array receives a copy of the projection matrix instead.
Note: This subroutine cannot be used to add to a display list.
| matrix | Specifies an array into which to copy a matrix. |
The example C language program scrn_rotate.c uses the getmatrix subroutine to get the current transformation matrix after manipulating it.
This subroutine is part of GL in the AIXwindows Environment/6000 Version 1, Release 2 with AIXwindows/3D Feature.
| /usr/include/gl/gl.h | Contains C language constant and variable type definitions for GL. |
| /usr/include/gl/fgl.h | Contains FORTRAN constant and variable type definitions for GL. |
