I have generated pointcloud -- ptCloud using pcfromkinect function ( as in the Matlab example) . Now I want to trim the pointcloud using
x = ptCloud.Location(100:200 ,100:200,1);
y = ptCloud.Location(100:200 ,100:200,2);
z = ptCloud.Location(100:200 ,100:200,3);
R = ptCloud.Location(100:200 ,100:200,1);
G = ptCloud.Location(100:200 ,100:200,2);
B = ptCloud.Location(100:200 ,100:200,3);
PTC.Location(:,:,1) =x;
PTC.Location(:,:,2) =y;
PTC.Location(:,:,3) =z;
PTC.Color(:,:,1) = R;
PTC.Color(:,:,2) = G;
PTC.Color(:,:,3) = B;
then pcshow(PTC)
but not working any sugesion or matlab file exchange files wiill be highy appreciated

I don't even know what you want to do. What does it mean to "trim a point cloud"? Do you mean crop? Remove outliers? "Trim" does not seem to be a precisely defined term in your context. Like for strings, trim means to remove leading and trailing white space. But I have no idea what you mean. Well, 2 ideas that I just gave but I still am not sure if it's one of those or something else.
