Volume Rendering- Help Needed

hi all,

i am working on a project that uses volume rendering using medical data…i googled it out and found some techniques like ray casting, shear warp etc algorithms…now i m confused do i really need to implement these algorithms for rendering or Open GL would take care of it(i.e. would it not be get done by just rendering slices with blending enabled)…?? plz help me out…

If you are interested in volume rendering and OpenGL I suggest you take a look at this link:


It describes well how to implement a volume renderer without using ray-casting.

thank u for your generous support…can you please tell me for which method should i go for a interactive(rotation, zoom in zoom out, translation) application…between ray casting and 3d texture based volume rendering.
