In-Depth Information
specifies which mip level to load. The base level is
specified by 0, followed by an increasing level for each
successive mipmap.
level
the internal format for the texture storage; can be either
an unsized base internal format or a sized internal
format. The full valid

combinations are provided in Tables 9-4
through 9-10.

the width of the image in pixels.
width
the height of the image in pixels.
height
the number of slices of the 3D texture.
depth
this parameter is ignored in OpenGL ES. It was kept
for compatibility with the desktop OpenGL interface.
Should be 0.

type
contains the actual pixel data for the image. The data must
contain (

) number of pixels with
the appropriate number of bytes per pixel based on the
format and type specification. The image data should be
stored as a sequence of 2D texture slices.
