Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

GLSCALE(3G)															       GLSCALE(3G)

NAME
glScaled, glScalef - multiply the current matrix by a general scaling matrix
C SPECIFICATION
void glScaled( GLdouble x, GLdouble y, GLdouble z ) void glScalef( GLfloat x, GLfloat y, GLfloat z )
PARAMETERS
x, y, z Specify scale factors along the x, y, and z axes, respectively.
DESCRIPTION
glScale 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 glMatrixMode) is multiplied by this scale matrix, and the product replaces the current matrix as if glScale 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 glScale is called are scaled. Use glPushMatrix and glPopMatrix 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 glEnable with the argument GL_NORMALIZE.
ERRORS
GL_INVALID_OPERATION is generated if glScale is executed between the execution of glBegin and the corresponding execution of glEnd.
ASSOCIATED GETS
glGet with argument GL_MATRIX_MODE glGet with argument GL_COLOR_MATRIX glGet with argument GL_MODELVIEW_MATRIX glGet with argument GL_PROJECTION_MATRIX glGet with argument GL_TEXTURE_MATRIX
