function glCopyTexSubImage3D(int $target, int $level, int $xoffset, int $yoffset, int $zoffset, int $x, int $y, int $width, int $height) : void
arguments
  1. int $target Specifies the target to which the texture object is bound for glCopyTexSubImage3D function. Must be GL_TEXTURE_3D, GL_TEXTURE_2D_ARRAY or GL_TEXTURE_CUBE_MAP_ARRAY.
  2. int $level Specifies the level-of-detail number. Level 0 is the base image level. Level n is the nth mipmap reduction image.
  3. int $xoffset Specifies a texel offset in the x direction within the texture array.

  5. int $zoffset Specifies a texel offset in the z direction within the texture array.
  6. int $x Specify the window coordinates of the lower left corner of the rectangular region of pixels to be copied.
  7. int $y
  8. int $width Specifies the width of the texture subimage.
  9. int $height Specifies the height of the texture subimage.
