## @deftypefn {Function File} drawShape (@var{type}, @var{param})
## @deftypefnx {Function File} drawShape (@dots{}, @var{option})
## Draw various types of shapes (circles, polygons...).
##
## drawShape(TYPE, PARAM)
## Draw the shape of type TYPE, specified by given parameter PARAM. TYPE
## can be one of 'circle', 'ellipse', 'rect', 'polygon', 'curve'
## PARAM depend on the type. For example, if TYPE is 'circle', PARAM will
## contain [x0 y0 R].
##
## Examples :
## @example
## drawShape('circle', [20 10 30]);
## Draw circle centered on [20 10] with radius 10.
## drawShape('rect', [20 20 40 10 pi/3]);
## Draw rectangle centered on [20 20] with length 40 and width 10, and
## oriented pi/3 wrt axis Ox.
## @end example
##
## drawShape(..., OPTION)
## also specifies drawing options. OPTION can be 'draw' (default) or
## 'fill'.
## @end deftypefn
function varargout = drawShape(type, param, varargin)
if ~iscell(type)
type = {type};
end
if ~iscell(param)
tmp = cell(1, size(param, 1));
for i=1:size(param, 1)
tmp{i} = param(i,:);
end
param = tmp;
end
option = 'draw';
if ~isempty(varargin)
var = varargin{1};
if strcmpi(var, 'fill')
option = 'fill';
end
end
# transform each shape into a polygon
shape = cell(1,length(type));
for i=1:length(type)
if strcmpi(type{i}, 'circle')
shape{i} = circleAsPolygon(param{i}, 128);
elseif strcmpi(type{i}, 'rect')
shape{i} = rectAsPolygon(param{i});
elseif strcmpi(type{i}, 'polygon')
shape{i} = param{i};
end
end
hold on;
h = zeros(length(shape), 1);
if strcmp(option, 'draw')
for i=1:length(shape)
h(i) = drawPolygon(shape{i});
end
