Display a Volumetric Image using a cloud of points

I’m trying to created a volumetric image using intensity values read from a .raw file. I have read the values into a buffer but do not know how to start drawing the object. I also have the slice(i think that is the word) dimensions (x,y,z). I’m sure this is possible to do but i do not know how to begin, perhaps a push in the correct direction from you? The search engine has not been helpful to me.

The method u r looking for is called splatting in literature. Have a look at this project for details.

See if this helps.
