Hi all,
I'm about to start coding an application where I want to visualise
some
medical data in 3D. I've never used OpenGL before, but from the
reading
I've done I think OpenGL is a good tool to allow me to achieve what I
want,
but I learned that OpenGL takes too much coding. here I have to read
DICOM images for my application. Can any one tell me how to do it?
Thax in advance

OpenGL ist a neat and straightforward API. Very easy to learn,
too.

DICOM has absolutely nothing to do with OpenGL. But I've once
tried to write a DICOM parser (reads simple RAW images). Took me
3 months, the format is absolutely nasty. IMHO it was designed b
people without practical knowledge. It should be a streamable
format, and achieves this with a absolutely crud padding scheme.
Really I wonder how this could become the standard in medical
imaging.

There is more to DICOM than "image format". And there is more
to visualizing medical images than you might imagine. You can find
a few packages that are written for medical image analysis and
visualization. Here is one of them http://mipav.cit.nih.gov/ .

Have a look at VTK (http://www.vtk.org/). It implements many things
you might need including a DICOM parser.

Try KB-Vol3D:
http://www.kbvis.com
There is a VC++ sample app to get you started.

There are a number of others, some proprietary, some public domain.

THe VTK and ITK toolkits are among the best.

Is it possible to perform normal operations like filtering, contrast
stretching , segmentation etc on DICOM images. After that I have to
render the images in 3D.

DICOM is a (among other things) an image file standard -- it doesn't
have anything to do with what you do with the images.

However, don't just jump in. Instead, research the field to know what is
available, and don't start coding until you need to implement something
better than what is already available. Unless this is a classroom
project or something similar...
