From: Cemil on 13 Feb 2010 08:54 hi, i'm using the nurbs toolbox from Paul Zhang and i think that the demonstration of democoons solves my problem. but i have a problem with understanding the code. does this section means the x,y,z values? pnts = [ 0.0 3.0 4.5 6.5 8.0 10.0; % transposed x-vector??? 0.0 0.0 0.0 0.0 0.0 0.0; % transposed y-vector??? 2.0 2.0 7.0 4.0 7.0 9.0]; % transposed z-vector??? why must the interval a non-decreasing interval of [0,1] and why it is not enough to give only two like [0.0 0.8] in this line??? crv1 = nrbmak(pnts, [0 0 0 1/3 0.5 2/3 1 1 1]); shortly: i don't understand the above line! i have six vectors: x1,y1,z1 and x2,y2,z2. the dimension of vectors x1,y1,z1 (8232 entries) are larger than the of x2,y2,z2 (7472 entries). is it a problem? the y1 and y2 vectors contains only negative values, is it a problem? last but not least, how looks the pnts of my vectors and the ucrv1, ucrv2, vcrv1 and vcrv2 when the range of x1 = [700 : 1500] , y = [-2 ... -2], z1 = [.....] and x2 = [700 : 1400], y2 = [-3 ... -3], z2 = [.....] ??? regards cemil

Then talk with Paul Zhang who wrote the code. Rune
