Algosim documentation: plane


Creates a new rectangular subset of a plane in ℝ³.



plane() creates the square [−1, 1]² × { 0 } ⊂ ℝ³.

plane(a, f, d, α) translates the square by a, scales it by diag(f), aligns its normal with d, and rotates it an amount α about its (normal) axis.

Since a plane is flat, the third component of f should be unity. Unless the two first components of f coincide, the resulting object will be a non-square rectangle.


If omitted, a defaults to ❨0, 0, 0❩, f to ❨1, 1, 1❩, d to ❨0, 0, 1❩, and α to 0.

The object is shown in the current scene and a reference to the object is returned.

The AdjustVisual function can be used to adjust the appearance of the rectangle. See Visual settings for a list of applicable settings.
