3D plotting with three input an one output.
显示 更早的评论
Hi All,
I have three variables to compute new data like Dt=x^2+y^2+z^2. I want to get a 3D plot to see how Dt change with three variable. My case study is below. Any help will be appreciated.
Best,
OA

What kind of 3D plot are you looking for?
You have used "isosurface" function here and how is the obtained result different from what you are expecting?

If I understand isosurface correctly, you are showing a surface that represents where ed=1 in your volumetric data. For this surface, there will be no variation in color due to ed because the value of ed is the same everywhere on this surface.
Are you instead trying to view the value of ed across your entire volume? If so, that is a 4D problem. You might find this answer helpful.
