Visualizing a 3-variable function in a 3D plot -- Wolfram Math

[Qturtle]

Hey
I have a function of x,y,z and i want to have a 3D graph of it. i was thinking maybe there is a color option that corresponds with the value of the function, something like DensityPlot in Wolfram but in 3D instead of 2D. the result should look like a box filled with semi transparent color that changes with respect to the value of the function, so that u have an idea of what's "inside", and not only what's in front of you.
ive tried ContourPlot3D but it doesn't give me a satisfying result. any ideas?

Hmmm... It sounds like you want something like this https://www.google.com/?gws_rd=ssl#q=4d+grapher
I'm not really sure what a good program is to do so, but a brief skimming led me to the result that if you don't want to pay, you should make your own, and represent the 4th dimension (your dependent variable) as a color. Sorry I can't offer up anything better than that.
