[Visualpython-users] Animating Mesh Surface

[Kadir H. <kha...@ya...>]

Hello All,=0A=0AI have a surface defined  as a Mesh in Visual as below:=0A=
=0Ax =3D arange(-350,350,50.0)=0Ay =3D arange(-350,350,50.0)=0A=0Az =3D zer=
os( (len(x),len(y)), float )=0Ax,y =3D x[:,None]+z, y+z=0A=0Aseasurf =3D Me=
sh((0,1,0), color.white, x, (sin((x+y)/1.2/(pi))-cos((x+y)/1.2/(pi)))*10.0-=
15.0, y)=0A=0Aseasurf.p =3D seasurf.model.pos*0=0A=0AI get the surface OK f=
or me.=0A=0AI tried updating pos values in mesh "seasurf" for y in time, bu=
t somehow could not manage it. Can anyone help me?=0A=0AThanks,=0A=0AKadir=

The Mesh object isn't a supported/documented Visual object, though 
perhaps something like it should be. It's just a routine in a particular 
example program faces_heightfield.py contributed by the originator of 
VPython, David Scherer. The only documentation there is, is the routine 
itself. So I'm afraid you're on your own as far as using this routine in 
your own program.
