How to install this app:

Update: Make sure to update to at least firmware 6940.
Connect the calculator to your PC; on the PC start the Connectivity Kit.
In the Connectivity Kit, make sure the Content tab is open. (Select Window > Content if necessary)
Drag the Graph3D.hpappdir folder into the Content tab. You may need to scroll the Content area to the bottom so that you can "drop" the hpappdir into the bottom of the list. Otherwise, you may inadvertently drop the hpappdir into the wrong location, such as an existing hpaddir.
Drag the Graph3D.hpappdir folder from the Content tab into your calculator or virtual calculator.

Alternate installation method for non-hpappdir versions

Update: Make sure to update to at least firmware 6940.
Connect the calculator to your PC; on the PC start the Connectivity Kit.
In the Connectivity Kit, click on the Content tab.
Click on the [+] symbol next to Application Library to expand the list of apps.
Right-click on Advanced Graphing and choose Copy and a copy named Advanced Graphing Copy will be created.
Right-click on the newly created copy, and select Rename. Rename it to Graph3D.
Now, double click on Graph3D and a new Content window should open.
In the Content window, click on the Program tab. Copy the source code from the graph3dv2422.zip file and overwrite the contents shown in the Program tab. Save using the icons near the top left of the connectivity kit window. These above steps basically save Graph3D into your "library" on your PC should you ever need transfer the app to other calculators/emulators.
Now, right-click on Graph3D and select Send to class: (All) to send it to your HP Prime calculator.
On the HP Prime, press the Apps key and select Graph3D.

Alternate installation method 1

Copy the Graph3D.hpappprgm file into your My Documents\HP Connectivity Kit\Content folder on your PC
Run the connectivity kit and connect your calculator to your PC (or optionally run the virtual emulator)
Drag the Graph3D.hpappprgrm file on the left pane of the connectivity kit window and drop it into the HP Prime in the same left pane.

Alternate installation method 2

Update: Make sure to update to at least firmware 6940.
Run the emulator, and press the [Apps] key to open the apps menu. Highlight the Advanced Graphing app and select the "Save" menu option at the bottom of the screen. When given the opportunity to name the copy, use Graph3D.
Open the [Apps] menu again and now select the app named Graph3D.
Open the Program Catalog and with Graph3D (App) selected, press [Enter] to open the source code in the Program Editor. Delete everything using [2nd] [Esc].
Copy the source code in the link below and paste it into the emulator (while the emulator is still in the now-blank source code file for the Graph3D app).
Exit the Program Editor and make sure that no warnings appear.
Test the app by plotting 1/3*(X^3*Y-X*Y^3)
If all is well, return to the [Apps] menu in the emulator. Then select Calculator > Connect To > HP Prime in the emulator program menu (with the actual HP Prime connected, of course).
You should see the "Send" menu option appear. Press "Send" and on the calculator, you should eventually see Graph3D appear in your [Apps] menu.
On the emulator, disconnect from the HP Prime.
On the HP Prime, turn off the calculator, and turn it back on (this "saves" the app into memory so that any warmstart -- i.e. soft reset -- will not revert to the previous memory state that did not have the app.)

How to use this app:

Enter your 2-variable function f(X,Y) into any one of the variables V0 through V9 in the [Symb] view. The variables MUST be uppercase X and Y.
Press [Plot].
Change the viewing window by pressing [Shift][Plot]; OR press [View] and choose among the list.
Change the grid size via [Shift][Num]; OR press [View] and choose among the list.
View the matrix of Z-values by pressing [Num]
More options by pressing [View]
You may have multiple formulas entered and selected for graphing.
After pressing [Plot] use the direction keys and the [Symb] or [Help] key for rotation. The [+] and [-] keys zoom in and out. Press [Esc] to exit, or touch the screen to exit the rotation. The interactive portion will time out after a minute (just press [Plot] again).
After the plot is displayed, tap the screen to bring up an interactive menu which includes the trace feature.
The [+/-] key is a shortcut for switching color mode and the [.] key will toggle trace mode.
While in trace mode (with multiple plots), pressing [+] or [-] will toggle between the multiple functions.

Some notes from iOS user rrshier: How to install on iOS (scroll pass the quoted section)

Changelog

Touchscreen gestures for rotation, zooming, and panning
Added new cross-section option for trace mode (see setup screen)
Fixed possible issues with zclipping
Fixed bug in trace mode when cycling colors; z-values were not updated properly
Smaller memory footprint and file size; removed Zvals, zColor, ptdef,tridef, and ldef
Removed all icons and replaced with generic icon background and text labels

Still to come: Finding local max/min, inserting tangent planes, additional color mode based on the color box in the [Symb] view (right now it's hard to tell which function is which in multi-graphs).

Download (Update: Make sure to update to at least firmware 6940.)
