The MOST Useful Animation Technique! - Displacement in Fusion

displacement is a really powerful tool in animation it's so powerful in fact that it's hard to boil its use case down to just one function it can warp objects it can add texture and it can be used to animate things in really interesting ways in this video I'm going to show you what it is and how you can set it up in DaVinci Resolve Fusion let's get into it [Music] displacement will let you warp the texture of objects by mapping them to something called a displacement map which means there are essentially two elements to this technique there's the actual displacement which is handled by a single node infusion and then there's the displacement map which is kind of where the creative part of this comes in because that can essentially be anything you want it to be so here in Fusion I have some text merged against the background I'm going to come up to our effects tab here and search for displays and put this in between our text and the merge so we're displacing the text before it merges over the background but this won't do anything until we get through some other steps first now a really common technique is to use a noise generator as a displacement map which I'm going to do here by bringing in a fast noise node and connecting this up to the green foreground input of the displace node I just for clarity at this stage the yellow input will handle whatever you want to displace and the green input is for your displacement map I'm going to bring in a second viewer here for a noise because it will be important to see what the noise looks like I'm also going to pin the inspector controls for the displace and the noise nodes so that they both stay in the inspector window then we don't have to keep clicking between them okay so as I've just now not very much going on here but from the displaced controls if I bring up the refraction strength a bit ticks will begin to warp slightly as you can see here if either end from the noise controls start to bring up the detail contrast and scale we could begin to see the effect this is having on the text this looks pretty funky right now but let's break down what's actually happening here and the displaced node a refraction channel is set to Luma meaning that the displace node is looking for the brightest most luminous parts of the map so the brightest parts of this noise here and warping our text according to that parameter by doing this we're able to create some really trippy effects with our text here using the controls of this noise so we can play around with the detail we could play around with the contrast and the scale of the noise to create a really unique looking text something else we could do is we can also increase the seed rate of the noise so that our text moves like this so as of right now we're displacing this in a radial pattern so you might be able to just see here that the text is refracting more at the edges and you can change the position of the radius if you want to go for a different look but you can also set this up to work across the X and Y axis which will give you individual refraction controls for both of those so you could for example add refraction to only the y-axis and make the text look like it's melting or something like that really powerful you also don't have to just displace text you could use this technique on any video or any shape that you want to I found this particularly useful when I'm trying to create little subtleties and animations so for example in this scene I'm using displacement on only the y-axis and that's sort of mimicking the feel of water as it's rising in this little chart here one last example here just because I think it's important to show this one displacement Maps don't have to just be noise it could be whatever you want and in that sense they can achieve a lot more than I've shown you here so in this example I've set up a little Vector magnifying glass and it's running across this word here using some keyframes but what I've done is I've created a second instance of this circle from the magnifying glass which you could do by copying the node and holding shift while you paste it an instance is just an exact copy of a node with all of the original controls so everything is controlled using one node but you could just have various instances across your node tree to connect them in different places now with this instance here I'm actually going to right click a few of the parameters and select the instance which will let me control them independently of the original one and what that lets me do is set it up as a solid Circle rather than just a bordered one like we have in the original a father and feed the center white background node now it gives me this little white circle animating across the screen in the center of the magnifying glass which I can then use as a displacement map to displace our text with and it gives us this sort of glass magnification effect across the text if you've got some creative examples of displacement Maps let us know in the comments I can't even know how many different uses there are or if you want more Fusion tutorials definitely give these videos a try remember
