How to simple wave a plane in jit.gl.sketch

Hi,
I want to build a plan that varies with the voice. the aim is, the voice can distort a plane. means voice amplitude will undulate. How can i made this, without using nubrs… i tried but can’t take control over ctlmatrix.

Thanks in advance

What exactly are you trying to distort?

Hi,
Thanks for your answer. What i need is shake the entire plane. Like a wave. Can i get that to work whit jit.gl.sketch?

Think you want jit.gl.graph. You can apply video textures to that.

Hi,

very similar, but in my case i have a entire plane, and whit jit.catch~ want to be able to shake the entire plane, all at once.

some combination of the jitter-render example patches should get you started.
specifically, Max5/examples/jitter-examples/render/jit.gl.mesh.bfg.maxpat

combine this with something like:Max5/examples/jitter-examples/audio/jit.poke~-asteroidgrowth.maxpat

provide us a patch showing what you’ve come up with and we can possibly offer more suggestions.

you need to study the example patches more carefully.
the nurbs-audiorender example starts with a 2 plane jit.catch~ (yours only has one).
it then creates a three plane matrix from this 2 plance matrix (which is necessary to serve as a control matrix for nurbs) using the jitaudio2nurbs javascript.

you can’t just plug the 1 plance jit.catch~ matrix into a 3 plane matrix and hope that it works.
i would just start from that example, and make small modifications until you understand what’s going on.

what have you tried? what didn’t work?
provide a *simple* patch demonstrating.

I disconnected matrix outlet from audio2nurbs.js and tried to expand the rolled plane to fit the entire screen. also tried to apply webcam texture in nurbs.

Hi Luis,
It might be easier to start by looking at some of the early Jitter recipes, many of which deal specifically with creating geometry from sound input. Some of the examples in the Jitter-examples folder can admittedly be a little difficult to tease apart.

Specifically,check out Recipe 22: CatchNurbs

Thanks Ben it really helps.
However, the plane is messed up when the matrix goes to ctlmatrix and displayed in nurbs. Is it possible to have a straight plane in nurbs? how to control individually each dot on nubrs?
I understood each highlight on jit.matix represents a dot in ctlmatrix, but how about taking control on each on?

Thanks

Luis Marques
