    a question about glTexImage2D

    hi all:

    when both width and height equal zero, will the glTexImage2D still generate a valid texture?

    From the spec:
    An image with zero width or height indicates the null texture. If the null texture is specified for level-of-detail zero, it is as if texturing were disabled.
