I want to use texture in jit.gl.nurbs controlled by jit.phys.multiple.

Because texture is a parameter that belongs to jit.gl.multiple and not to jit.phys.multiple, I´m trying to combine these three functions in order to introduce texture in nurb controlled individually.

The next attached patch is what I want to achieve, and needs to incorporate the mentioned texture parameter applied individually to each nurb;

And the next patch is the nearest approach that I have made to control every texture nurb individually, but it´s not the output that I am searching (that has been shown at the first patch)

Hi all,
I want to use texture in jit.gl.nurbs controlled by jit.phys.multiple.

your first patch works as expected, "jit.phys.multiple" control the points of one "jit.gl.nurb" and the texture "eg" is applied ?

If you want many nurbs and many different textures you have to use "jit.gl.multiple" (like your 2nd patch) or "poly~" .

I´m stuck with this problem a couple of weeks.

I know that my first patch works as expected controlling the positions points of the nurbs, and yes, applying only one texture, "eg".

I know that to deal with many different textures I have to use "jit.gl.multiple" (as in the second patch), the problem is that the nurbs position output is not the desired one, that must be like in the first patch. Any clues why is this happening?

About the "poly~", I don´t know how to apply in this issue, any examples? I will look at the tutorials.

I have been reading "poly~" references, and it seems that is a tool to manage different voices sounds, I don´t find the relation with multiple textures.

Please help, hehe.

Thank you very much Mathieu! I think that this is what I was looking for!

I will study it in a couple of hours and I´ll let you know.

I have been trying to translate yours approaches to the whole patch (attached).

The problem is the behaviour of every single nurb. These nurbs are slim planes, with a gradient colour, that acts like lines between objects. You can see this at the attached patch.

Please let me know if it´s not clear enough. You are helping me a lot.

The same, but with your first multiple patch approach.

I don´t know if the issue is well explained, please let me know.

It's not easy to understand what you want to do with "jit.gl.nurbs" because this is a big patch.

You want to generate connections between objects with "jit.gl.nurbs" ?

Hi ALI-I-TRUC
It's not easy to understand what you want to do with "jit.gl.nurbs" because this is a big patch.

I want to generate connections between objects with nurbs.

These nurbs, that look like lines, must be nurbs and not lines, because I want to paint them with a gradient colour.

A gradient colour that goes from the colour of one of the objects that links, to the other object color.

It is a big patch, yes, but the problem that I need to solve is in the little one, the one that has been updated with yours ideas ´texture gradient´. I have attached the big one, only to send the position data to update the nurbs positions.

With "jit.gl.path" you could make connections and generate gradient like in this patch .

If you want more connections, "poly~" could do the work ...

I hope it can help you a little...


in your patch if you want to see the gradient you have to rotate (90°) your texture; or change "jit.expr" to "jit.expr @expr (in[0]*(1-norm[1]))+(in[1]*norm[1])"

It looks a good solution. I didn´t know this propperty of jit.gl.path.

I´ll try to apply in my patch and I´ll let you know if it works.

Thanks for your help, has been difficult days.

I have been playing with your "jit.gl.path" and I have a couple of doubts:

- Is this possible to link more than three objects? I have been trying but I couldn´t.

-If this is possible, Can I enable parts of this path, I mean, to able connections between some objects and to enable others?

With "append" message, you add lines, and with "setscale" you can specify a segment scale, with scale 0, you can make it invisible.
