[Houdini Tutorial] 0029 Spectrum Visualizer (Slow version) 

Fantastic tute. Thanks very much. Clear and easy to follow. It's great to have some vex explained along the way that shows your thought process as your typing it. Really helps when trying to learn it!

Great tutorial. I was lost a bit with the vex, but really enjoy listening to the way you think your way out of want you want to express visually ! Thank you.

I´m a animation design Student , thanks a lot for the tutorials!

Is there actually a benefit to using his VEX method for extrusion over the polyextrude node? He mentioned that if you used the polyextrude node you would need to use a for loop to run each primitive for this to work, but I don't think that's the case. I created a polyextrude node and set the distance scale to the @dist attribute created in this workflow and then set the distance to parameter in the polyextrude node to 0.994 and the results are identical to his. Not sure if there is some of speed advantage to using the vex method but just for simplicity I would like to just stick with the polyextrude node if possible. Am not a vex expert yet ha so this would help me create my own animations better.

Thanks Junichiro, I'd love to see something like this but using MIDI files instead of audio!

Looks like setting setting the unit values of the spectrum node to "Current Time Slice" fixes the weird sync issues...

Thanks for the excellent tutorial, previous ones are really great too! Keep it up.

thank you very much for this one.. lots of amazing info, as always:) i just recreated this setup, it was fun.. i fractured sphere into 500 pieces, packed them, and transfered normals from original sphere..after that: @P += @N * @dist; and that's it.. i'm planning to animate points used for fracturing.. that could look nice.. but slow to simulate..

For some reason for me. No matter how many times I go over it, the adding the triangles to the points just doesn't work: int top = addprim(0, "poly", newPts[0], newPts[1], newPts[2]); Its the one line and seems to have zero effect. No errors just no effect. Any ideas?

Very helpful tutorial! Is it possible to use a "polyextrude" comp to extrude the primitive? Thanks Junichiro

cool, but Extrude + Distance scale make this operation faster.

hello mine did not work, the points are not in the middle, maybe because i changed the size after making the sphere? the points are matching each vertex, houdini v18.5

what do i do if i want to visualize the entire audio clip

Beautiful

i have error wen i import some music but when i copz node from your file it works.. i have a apretice version. and your file works when i download it

Thank You very much!

Very cool! Thanks you!

This is way over my understanding of vex. My second year in Houdini but still not capable of understanding vex at this level :( .
