v4 Weird offset bettween Graphics and DisplacementSprite

[jstoone]

Hi

I am using a displacement map to distort three graphics lines. And since the lines have a speed, I need to move the displacement space at the same speed as the points, which define the lines. I do this, so that the line keeps it shape, and doesn't "wave" around. But it seems like there is an offset in the speeds at which they move, mostly at lower speeds, which makes the line change a bit of its shape.

Is there a better way to achieve this effect, or is there some local/global positioning I'm overseeing with Pixi.js?
Would It make sense to move the PIXI.Graphics themselves instead?

Here is a simplified version of my project:

There is also some jittering, which I'm unsure if is caused by missing antialiasing or something else... If any of you can spot how to smoothen out the graphics I'd be very happy. But the displacment + graphics offset mentioned above is my main priority so far.

Feel free to ask any questions, if something needs to be clarified.

Your case is interesting, I'll help you later when I wont be that tired

Thanks again Ivan, I really appreciate it!

How big are graphics coords? I'm still not here, but I remember there were about 4 threads about precision this month. If you have something like x1=2125 x2=2126 coords in graphics, you can just set graphics.position.x = 2000 and use local coords 125 and 126.
