Re: [Scilab-users] Compute normals to 3D surface

Lester, To just show the vector arrows close to level Z ~ 0, you can define the # of points for each parametric coordinate of the Mobius strip: Nl = 40; // long axis #points Ns = 10; // short axis #points u = linspace(0,2*%pi,Nl); v = linspace(-0.5,0.5,Ns); and then at the end of the code

Re: [Scilab-users] Compute normals to 3D surface

Hi Lester, Try xarrows(). At the end of your code, add: // Compute normals to surface [x1,y1,z1]=surfnorm(x,y,z); sf = 0.2; // arrows scale factor x1 = sf*x1 + x; y1 = sf*y1 + y; z1 = sf*z1 + z; // Plot normal vectors to surface xarrows([x(:)';x1(:)'],[y(:)';y1(:)'],[z(:)';z1(:)'],-1,2)

Re: [Scilab-users] hist3d() puzzling rendering

Hi, Preserving the color of the original hidden faces under interactive rotations, does not seem to be a bad idea. It allows assessing what parts of the objects are hidden under the original choice of view angles. The behaviour of plot3d is similar. Regards, Rafael

Hi Jen, Several of the arguments you would like to use do not seem to be valid GlobalProperty members for plot(). Maybe you could use a function that takes as input a proper graphics handle and your list. Herein a quick and dirty example: //START OF CODE function gce_list(h, list0) n =
