On another forum based site I was informed that the OpenGL-es in xcode could display DICOM images – could anyone verify this as I have tried with no success. Does anyone have any suggestions of sample code – i need something similar to GLImageProcessing sample code.

thanks in advance

    OpenGL is agnostic to image file formats. It really boils down to extracting per-pixel RGBA values (or something similar) from your image and then using glTexImage2D to create the texture.

    You might want to search for libraries reading pixel data from JPEG first, as DICOM seems to store images in that format (according to Wikipedia):

    Pixel data can be compressed using a
    variety of standards, including JPEG,
    JPEG Lossless, JPEG 2000, and
    Run-length encoding (RLE). LZW (zip)
    compression can be used for the whole
    data set (not just the pixel data) but
    this is rarely implemented.
