comet3d
3D comet animated plot
Syntax
comet3d(z) comet3d(x, y, z) comet3d(x, y, z, Lf) comet3d(x, y, fun) comet3d(x, y, fun, Lf) comet3d(...,"colors", c)
Parameters
- x
- a real vector or matrix. Default =
1:np
,np
being the number of points of the trajectory. As a matrix, each column defines the x coordinates of the trace of an individual comet. - y
- a real vector (default value =
1:np
) or matrix. As a matrix, each column defines the y coordinates of the trace of an individual comet. - z
- a real vector of length
np
, or a matrix withnp
rows. As a matrix, each column defines the z coordinates of the trace of an individual comet.nc=size(z,"c")
is the number of comets simultaneously drawn. - Lf
- a real scalar in the interval
[0,1[
. Default value is 0.1: It defines the Leading fraction of the comet's trace. Thek=Lf*np
most recent points are plotted in thicker line. - fun
- a scilab function with syntax
z=fun(x,y)
. - c
nc
colors of thenc
comets traces. They may be specified as a vector ofnc
color indices or color names or "#RRGGBB" hexadecimal color codes. Or by a matrix (ncx3) of[r,g,b]
vectors of Red-Green-Blue intensities in the [0,1] interval.
Description
If (x,y,z)
are three vectors with the same number of elements, this
function draws a 3D comet animated plot. The plot is made of three parts:
a head | mark that shows the current (x(i),y(i),z(i)) position. |
a body | consisting in the k=round(Lf*np) most recent points
of the trajectory, displayed as a thicker part of the trace. |
a tail | that shows the [x(1:i-k), y(1:i-k), z(1:i-k)] part of the curve. |
if z
is a matrix and x
and y
are vectors, then animated curves are drawn for each triple
(x, y, z(:,j))
.
if x,y,z
are matrices with the same dimensions then animated curves
are drawn for each triple (x(:,j), y(:,j), z(:,j))
.
comet3d(x, y, fun,...)
computes the z
vector as
z(i)=fun(x(i),y(i))
.
comet3d(..,"colors",c)
can be used to set the colors of each
trajectory.
