Hello everyone, I have built a convexhull from a list of points using the ConvexHully function of scipy.spatial
H=ConvexHull(points) PH=H.points vh=H.vertices sh=H.simplices go.Mesh3d(x=PH[:, 0],y=PH[:, 1], z=PH[:, 2], name='Hull', showlegend=True, color='gray', i=sh[:, 0], j=sh[:, 1], k=sh[:, 2], opacity=1, alphahull=1, showscale=False)
and on the other hand I have drawn a surface from a grid, using go.Surface.
tx=grid ty=grid tz=grid X = np.linspace(min(tx), max(tx)) Y = np.linspace(min(ty), max(ty)) X, Y = np.meshgrid(X, Y) Z = griddata((tx,ty),tz,(X,Y), method='linear) go.Surface( x=X,y=Y,z=Z, colorscale=blues, opacity = 1, name='Topography', showlegend=True, showscale=False)
I would like to erase the part of the convexhull that is above the surface.
