Launch Scilab and write the following command : exec(SCI+'/contrib/surface/builder. Unzip the file in your Scilab contrib directory (SCI+\contrib)ģ. contour level curves on a 3D surface eval3d values of a function on a grid eval3dp compute facets of a 3D parametric surface. vecteur réels de même taille (points 3D).

The function returns the x -, y -, and z - coordinates as three 21 -by- 21 matrices. The returned ellipsoid has center coordinates at (xc,yc,zc), semiaxis lengths (xr,yr,zr), and consists of 20-by-20 faces. This new function generates a regular grid from scattered input dataĢ. Aide de Scilab > Graphiques > 3dplot > geom3d. Description example X,Y,Z ellipsoid (xc,yc,zc,xr,yr,zr) returns the x -, y -, and z -coordinates of an ellipsoid without drawing it. This exemple displays the picture below Data is a matrix : each column has to contain X,Y and Z data points (real only).The scaling factor is the ratio beetween the interpolated grid and the smallest vector in your data. The fist element is the X vector, the second one is the Y vector and the third one is the Z matrix of the interpolated data. 1.2.34 fplot3d1 3D gray or color level plot of a surface defined by a function.
