Animating Line

vvvv beta question
1

Hola a todos,
how can “animate” a line like the video attached?
I’m making a new installation with a lot of element around a map and I need to connect the name to a point.
Usually I use a quad mask in order to make a transition effect, but in this case I think is impossible, too much element

thx

Hi, use Rope DX11 and animate (translate transform) the UV coordinates.

Here you go, sample patch in the attachment.
There is lot of room for improvement (to make it with 4 triagles only, but with constant width and uv’s not deformed)

it should be possible, the core of the solution generates list of vertices and uv coordinates for geometry buffer.
but why would you do that? :) let dx9 rest in peace. even with a card that does support only shadermodel 4.0, you can still use many of the dx11 benefits.
