NAME
glTranslated, glTranslatef -- multiply the current matrix by a translation matrix
C SPECIFICATION
void glTranslated(GLdouble x,
GLdouble y,
GLdouble z)
void glTranslatef(GLfloat x,
GLfloat y,
GLfloat z)
PARAMETERS
x, y, z
Specify the x, y, and z coordinates of a translation vector.
DESCRIPTION
glTranslate moves the coordinate system origin to the point specified by (x, y, z). The translation vector is used to compute a 4x4 translation matrix:
The current matrix (see glMatrixMode) is multiplied by this translation matrix, with the product replacing the current matrix. That is, if M is the current matrix and T is the translation matrix, then M is replaced with M * T.
If the matrix mode is either GL_MODELVIEW or GL_PROJECTION, all objects drawn after glTranslate is called are translated. Use glPushMatrix and glPopMatrix to save and restore the untranslated coordinate system.
ERRORS
GL_INVALID_OPERATION is generated if glTranslate is executed between the execution of glBegin and the corresponding execution of glEnd.
glTranslate 是OPENGL的一個繪圖函式，指移動當前繪圖原點的意思。
語法： glTranslated(double x, double y, double z)
例如, GL.glTranslated(0.0, 0.8, 0.0) ，即將當前繪圖原點向Y軸方向移動0.8個單位。
