When we set vertexdata position, we can check if vertex y are higher than 0 and if YES, we skew vertex. So knowing that, imagine that we decide to get only vertex higher than zero, and not all of them but every three vertex. Could be something like this:
autocam off
sync on
make object cylinder 100,10
set object cull 100,0
lock vertexdata for limb 100,0
vertices = get vertexdata vertex count()
for i = 0 to vertices
inc a
if a>3 then a=0
x# = get vertexdata position x(i)
y# = get vertexdata position y(i)
z# = get vertexdata position z(i)
if y#>0 then set vertexdata position i,x#*1.2,y#,z#*1.2
if y#>3 and a=1 then set vertexdata position i,x#*1.2,y#-6,z#*1.2
next i
unlock vertexdata
position camera -10,20,-30
point camera 0,0,0
do
g#=g#+0.04
yrotate object 100,g#
set cursor 5,5:print vertices
sync
loop
And for animate vertex, could be like this:
ink rgb(100,90,0),0:box 0,0,40,80:ink rgb(70,40,0),0:box 0,39,40,41
box 0,0,2,40:box 19,40,21,80:box 0,0,40,2
get image 1,0,0,40,80,1
for i= 1 to 5700
col=rnd(50)
dot rnd(20),rnd(20),rgb(150+col,100+col,100+col)
next i
blur bitmap 0,1
get image 2,0,0,20,20,1
