Method GL.glTranslate()


Method glTranslate

void GL.glTranslate(float|int|array(float|int) x, float|int|void y, float|int|void z)

Description

GL.glTranslate produces a translation by ("x","y","z"). The current matrix (see

GL.glMatrixMode) is multiplied by this translation matrix, with the product replacing the current matrix, as if GL.glMultMatrix were called with the following matrix for its argument: .sp .ce .EQ left ( ~ down 20 matrix { ccol { 1~~ above 0~~ above 0~~ above 0~~ } ccol { 0~~ above 1~~ above 0~~ above 0~~ } ccol { 0~~ above 0~~ above 1~~ above 0~~ } ccol { "x"~ above "y"~ above "z"~ above 1} } ~~right ) .EN .sp .RE If the matrix mode is either GL_MODELVIEW or GL_PROJECTION, all objects drawn after a call to GL.glTranslate are translated.

Use GL.glPushMatrix and GL.glPopMatrix to save and restore the untranslated coordinate system.

Parameter x

Specify the x, y, and z coordinates of a translation vector.

Throws

GL_INVALID_OPERATION is generated if GL.glTranslate is executed between the execution of GL.glBegin and the corresponding execution of GL.glEnd.
