PLANE PLOTTER - draws a plane defined by a point and normal vector
the plane will be drawn as a square of specified range centred around 'point'
!!!! Acknowledgement: !!!!!!!!!!!!
this is an implementation of a method described by Roger Stafford on the MATLAB answers forum.
(https://www.mathworks.com/matlabcentral/answers/291485-how-can-i-plot-a-3d-plane-knowing-its-center-point-coordinates-and-its-normal#answer_226405)
The actual method is taken straight from the forum, I simply added some input features etc. to make it universal and more convenient to use by organizing the input structure
Syntax: p=planePlotter(point, normal)
p=planePlotter(point, normal, ...)
planePlotter(point, normal)
planePlotter(point, normal, ...)
INPUTS:
point - xyz coordinates (1x3 or 3x1) of a point in the plane
normal - normal vector to the plane (1x3 or 3x1)
OPTIONAL INPUTS:
optional inputs can be specified as Name-Value pairs to give additional
graphics choices
'range': scalar; defines the range of the plane that will be graphed
(size of the square); default=1 resulting in a 2x2 square
'gridlines': scalar, defines how many grid-lines will be drawn on the plane;
default=1 -> no lines; 2 -> edges drawn; 3 -> edges plus 4 squares; etc
'FaceColor': string, RGB triplet or hexidecimal string; default='green'
'FaceAlpha': scalar; default=0.3
'EdgeColor': string, RGB triplet or hexidecimal string; default='black'
OUTPUT:
for simple drawing, the output does not have to be defined
defining the output p saves the graphics element to allow later editing
Example 1:
% plane at 45º angle through origin
% specifying only point and normal vector leaves optional inputs as
% default resulting in a green plane with no lines:
point=[0 0 0];
vector=[1 1 1];
planePlotter(point, vector);
axis equal
% we can add the point and vector to this as illustrations:
hold on
scatter3(point(1), point(2), point(3), 500, '+', 'LineWidth', 2);
quiver3(point(1), point(2), point(3), vector(1), vector(2), vector(3), 'Color', 'r', 'MaxHeadSize', 1, 'LineWidth', 2);
view(2);
Example 2:
% drawing the same plane with a range of 5 (resulting in a 10x10 square)
% with gridlines drawing 1x1 grid squares (11 gridlines including 0 and 10)
% with teal faces and magenta edges
p=planePlotter([0 0 0], [1 1 1], 'range', 5, 'gridlines', 11, 'FaceColor', [0, 1, 1], 'EdgeColor', '#FF00FF');
axis equal
% specifying the graphics output (p) allows us to change individual graphics settings afterwards
p.FaceAlpha=0.8;
p.FaceColor='blue';
p.EdgeColor='r';
p.LineWidth=3;
p.LineStyle=':';
