`coneplot`

Draws 3-D vectors of a vector field as cones.

Category: Graphics > 2-D and 3-D Plots

Syntax

coneplot(X, Y, Z, U, V, W, Cx, Cy, Cz)

Places cones at the points (Cx, Cy, Cz) of the field (U, V, W) defined on the grid (X, Y, Z).

h = coneplot(___)

Also returns the patch object.

Description

At each requested point the field is interpolated, and a cone is drawn pointing along the vector with a size proportional to its magnitude. Combine with camlight and lighting to give the cones volume.

Input arguments

X, Y, Z: Grid coordinates, as returned by meshgrid.
U, V, W: Components of the vector field on the grid.
Cx, Cy, Cz: Coordinates where the cones are placed.

Output arguments

h: A Patch object holding all the cones.

Example

Radial field

[X, Y, Z] = meshgrid(-2:2);
U = X; V = Y; W = Z;
[cx, cy, cz] = meshgrid(-1:1);
h = coneplot(X, Y, Z, U, V, W, cx, cy, cz);
disp(class(h))
view(3)

Output

matlab.graphics.primitive.Patch
