3D graphing

A 3D version of the calculator would be great - we don't have that feature built in yet, but hopefully someday soon!

In the meantime, you can mimic 3D graphing like this: https://www.desmos.com/calculator/nqom2ih05g

    you should also have a point that changes the view of the 3d graph kindof like this one https://www.desmos.com/calculator/shw1wthey5

    Is this a project or just a subjunctive situation?

    How can I graph my own things on this? The formulas are so complex, I don't know where to put my functions!

    You should also consider to have a perspective, zooming and create the possibility of rotating the graph with a point and with sliders so that you can also animate a axis. Made the whole chart also a bit more clear and added some more explanatory comments.

    Has anyone here played Eye Wire before? If not, then go check it out. It solves the problem of 3D movement by allowing you to scroll through a cross-section of the block. The same could be applied to graphs with 3 variables.

     

    BTW, Eye Wire is a cool game ;-)

    A bit confusing.

    With something like this: https://www.desmos.com/calculator/omcaw59kxc 

    You can even plot the solution to an equation f(x, y, z) = 0

    Sorry its extremely laggy - turns out doing this requires a lot of calculating.

    Desmos is great for 2D graphs, but 3D plotting is computation-intense and require GPU processing.
    For real-time rendering of 3D equations you can try this:

    This is an enhanced version from the one made by Ansgar F26. It can accept any function now, instead of being stuck to only using f, g and h.

    Would someone be kind enough to help me by showing (if possible) how to place the point of intersection (s1, s2, s3) between the plane and the line through the points (i) and (r), so that it lies on the line and not next to it. The coordinates seem to be calculated correctly, but the placement in the coordinate system turns out wrong:

    Line-plane-intersection

    Well, after redrawing the line the point of intersection seems to be right on spot:

    Line-plane-intersection

    Intersection of two lines in 3d:

    Line-line-intersection
