Here is an example for ploting several clusters with different colors xyz1=rand(10,3) ;// the first cluster points xyz2=3+rand(8,3);// the second cluster points drawlater() //disable drawing param3d(xyz1(:,1),xyz1(:,2),xyz1(:,2)) e1=gce();//the handle on the polyline e1.line_mode='off';e1.mark_mode='on'; e1.mark_size=2;e1.mark_foreground=5; param3d(xyz2(:,1),xyz2(:,2),xyz2(:,2)) e2=gce();//the handle on the polyline e2.line_mode='off';e2.mark_mode='on'; e2.mark_size=2;e2.mark_foreground=3; drawnow() //enable drawing There is somewhere in the Scilab Code a fortran code that realizes clustering of 3D datas. I have to look a it , i will send it to you Serge Steer INRIA
