As shipped in IRIX 6.5. First release of IRIX 6.5.
NAME fglScaled, fglScalef - multiply the current matrix by a general scaling matrix FORTRAN SPECIFICATION SUBROUTINE fglScaled( REAL*4 x, REAL*4 y, REAL*4 z ) SUBROUTINE fglScalef( REAL*4 x, REAL*4 y, REAL*4 z ) PARAMETERS x, y, z Specify scale factors along the x, y, and z axes, respectively. DESCRIPTION fglScale produces a nonuniform scaling along the x, y, and z axes. The three parameters indicate the desired scale factor along each of the three axes. The current matrix (see fglMatrixMode) is multiplied by this scale matrix, and the product replaces the current matrix as if fglScale were called with the following matrix as its argument: | | x 0 0 0 | | | 0 y 0 0 | | | 0 0 z 0 | | | 0 0 0 1 | If the matrix mode is either GL_MODELVIEW or GL_PROJECTION, all objects drawn after fglScale is called are scaled. Use fglPushMatrix and fglPopMatrix to save and restore the unscaled coordinate system. NOTES If scale factors other than 1 are applied to the modelview matrix and lighting is enabled, lighting often appears wrong. In that case, enable automatic normalization of normals by calling fglEnable with the argument GL_NORMALIZE. ERRORS GL_INVALID_OPERATION is generated if fglScale is executed between the execution of fglBegin and the corresponding execution of fglEnd.
