		<description>Thanks I updated the link :-)

Anyway following the istructions I spent just 30secs to find the new link.</description>

		<description>While trying to reproduce the effect I watched the video again and saw this:
http://www.youtube.com/watch?v=qx4VLO2u1E0

That explain the &quot;footage&quot; part.

I found multiple methods to move the nails based on the footage:
-using a displaced plane as a PFlow emitter and the nails as particles, it&#039;s fast and does the trick.

-displacing the nails on a single axis with prepared footage so that the nails don&#039;t deform.

-scripting the &quot;stick to a displaced plane&quot; part avoiding the use of pflow (might be more of an &quot;academic&quot; solution than pflow)

-scripting directly the position of the nails based on the luminance of the footage (pain in the ass if you ask me)</description>

		<description>I didn&#039;t look too much but I don&#039;t think it&#039;s as simple as it looks ^^
first the map for the movement of the nails, I don&#039;t think it was rendered, it&#039;s probably live footage, the work start here, I&#039;m not sure if it&#039;s only normal footage that was used to give an illusion of depth or something more complex, if it&#039;s complex,  I can think of multiple methods to get something that works as a height map:
- lighting tricks with black background , subject with very few contrasts, lighting perpendicular to point of view.
-reconstructed depth from 2 or more cameras at different positions (there is some software solutions available for that and at this level of detail it works like a charm).

After that the movement of the nails are &quot;linked&quot; to the footage in a similar way as displacement, the map associated with displacement move vertices&#039;s along normals based on luminance values of the map while in this case the map is used to control the position of the nails on an axis between a max and a min position also based on the luminance of the map.

I think it&#039;s possible without scripting I already did something similarsome time ago, I captured a visualization from an audio player and then used it in 3dsmax on an array of cubes to make them &quot;jump&quot; along the music.</description>
