SUMMARY

The discussion focuses on extracting coordinates from a 3D plot in Mathematica using the Reap and Sow functions. The specific code provided is: Reap[Print[Plot3D[x^2 y + y^2 x + 2, {x, -1, 1}, {y, -1, 1}, EvaluationMonitor :> Sow[{x, y, x^2 y + y^2 x + 2}]]]][[2, 1]]. This method effectively captures all plotted points' coordinates, allowing for further analysis or manipulation. The discussion clarifies the syntax involving the colon and greater-than symbol, which is crucial for proper function execution.

I have a 3D Plot in Mathematica and I would like to get coordinates for points (all points) that were plotted.

Reap[
Print[Plot3D[x^2 y + y^2 x + 2, {x, -1, 1}, {y, -1, 1}, EvaluationMonitor :> Sow[{x, y, x^2 y + y^2 x + 2}]]]
][[2, 1]]

Note, despite it not being particularly that there is a : followed by > in that.
