object_draw.m

用MATLAB做的3D图形的变化,这个是范例,希望会帮到大家

function h = object_draw( obj, c )

% h = object_draw( obj, c )
% draw object obj which is in homogeneous coordinates
% c is an optianl parametr which, if supplied, specified the colour of the drawing
% return a handle to the drawing

% get the oridinary cooridinates
img = obj(1:2,:) ./ repmat( obj(3,:), 2,1 );

% draw it
h = plot( img(1,:), img(2,:) );

if nargin == 2
  set(h,'Color',c);
end

return;
