animate points

[puma.snyder]

Hi, got another problem

I have the following setup (see attachment).

9 points with an attribute "HEIGHT" (describing the height for each point)

An attribCreate sop which animates the existing attribute "$HEIGHT*chf("../add1/pt0x", $F)"

A point sop with $HEIGHT in ty

No, how can I achieve the following animations (in houdini select, so no chops)

Move each point to its final position

1: with the next point always starting 1 second after the previous started

2: with the next point always starting after the previous reached its final position

3: but instead of individual points move each complete row (or column) to its target position using the methods described above

4: how to simulate the lag chop with expressions, so that (optionally) each point temporarily moves a bit above its final position

Thanks in advance

Ooops...wrong expression....replace with

$TY+fit($F,$START+$DELAY*($PT),$START+$DELAY*($PT+1)+$DELAY,0,$HEIGHT)

Wow, thanks Andrew!

so

1=

$TY+fit($F,$START+$DELAY*($PT),$START+$DELAY*($PT+1)+$DELAY,0,$HEIGHT)

2=

$TY+fit($F,$START+$DELAY*($PT),$START+$DELAY*($PT+1),0,$HEIGHT)

3a (row by row) =

$TY+fit($F,$START+$DELAY*wrap($PT, 0,3),$START+$DELAY*wrap($PT,0 ,3)+$DELAY*.5,0,$HEIGHT)

3b (row by row) with additional delay (small) per point

$TY+fit($F,$START+$DELAY*wrap($PT, 0,3)+($PT*5),$START+$DELAY*wrap($PT,0 ,3)+($PT*5)+$DELAY*.5,0,$HEIGHT)

3c (row by row) with additional delay (high) per point

$TY+fit($F,$START+$DELAY*wrap($PT, 0,3)+($PT*15),$START+$DELAY*wrap($PT,0 ,3)+($PT*15)+$DELAY*.5,0,$HEIGHT)

>>> 3c causes the points in the next row to start, before the last points in the previous row have finished . I cant figure out how to modify this expression so this does not happen

Any ideas here?

4= ???

well, this is nearly perfect, but I would like to have another option

right now it takes for every point the same amount of time to reach its target position, how can I make them all travel at the same speed, so that points with a higher Height attribute take more time to reach final position ?

Thanks again

Hmmmm...may be this helps...

PS

its about: "right now it takes for every point the same amount of time to reach its target position......"

If You want offset in time just modify expression:

0.8 + point("../sop11",$PT,"ddtime",0) for example

You can also randomize speed attribute

PSS

cofee + cigarettes =

Delete "attribcreate3" sop

And replace "parameter1" vop with "constant" vop (float = 0)
