Help on an effect

[darcome]

Hello everyone,

 

in this link,

if you launch the application and then try to change the color of the juke, there is a "wave" effect...

 

How can you obtain it with babylonjs?

 

Thanks in advance for your precious help!

Wow it's cool !

I think it is modifying the geometry of the mesh. Maybe it is possible using a single material where the vertex shader modifies the geometry according to a function (function that looks like exponential until a max value where the animation is stopped).

I cannot say more

[darcome]

Maybe it could be done with the help of the wave effect of hte pixel and vertex shader like in the CYOS playground?

[julien-moreau]

I think it can indeed.

But you have to find a function that computes the wave transformation in function of time and in a particular interval. Because the CYOS example is constant

[darcome]

I think it could be possible set an interval, for example, 1 second, and then put back the normal shader.

 

The problem is that I don't know how to make the effect begin for example start from the back of the car and then propagate to the front of the car

[julien-moreau]

I think the wave effect should be computed using the current vertex position on x or z (not y because y is the height) in function of the time. Or a gaussian moving in function of time
