1. ## Sound Driven Deformations

This might help: http://www.tokeru.com/cgwiki/index.php?title=HoudiniChops#Dynamics_driven_by_chops
2. ## VEX quaternion to vectors

...and to finish that thought, now that you have a matrix, you can then take a vector that points along z, and multiply it by the matrix to give you your @N, and a vector that points along x to give you your @up. Example here: http://www.tokeru.com/cgwiki/?title=HoudiniVex#optransform_to_do_a_motion_control_style_camera
3. ## Sine waves color

http://www.tokeru.com/cgwiki/index.php?title=JoyOfVex13#Exercises but more generally http://www.tokeru.com/cgwiki/index.php?title=JoyOfVex In your case you could do something like float sin = fit(sin(d - @Time*4), -1, 1, 0, 1); vector col_hi = chv('col_high'); vector col_lo = chv('col_lo'); @Cd = lerp(col_lo, col_hi, sin);
4. ## a sharing system in Houdini??

wot tim said. sharing_emit_points.hipnc
5. ## Constraints mixing pops and bullet

That's really cool!
6. ## Creating fibrous language with attractor points

You deleted a wire in the setup:
7. ## Help With Speeding Up Render

That sounds like a nice repro to send to sidefx, good thing to poke Kai about.
8. ## Read only expression on left side of assignment

Works fine here, sounds like a stuck wrangle, happens sometimes. Try copying to a fresh wrangle.
9. ## Creating fibrous language with attractor points

Ha, I'd carefully balanced the emitters and forces to keep it 2d. On the emitters, set the variance to have some random y and z, that'll push it into 3d. Same goes for pushing the axis force spheres along z, they'll start to push particles off the 2d plane.
10. ## Scaling packed Objects with VEX

I have an example here: http://www.tokeru.com/cgwiki/index.php?title=HoudiniDops#RBD_deintersect_via_scaling_up_geo
11. ## Creating fibrous language with attractor points

Maybe this? Just a bunch of axis forces, point emitters, trails, and setting alpha so you get that multiplicative effect in areas of high density. trail_graph.hip

Might help:
13. ## Unroll a planar curve

Quite a few answers come up if you search for 'unroll' here. Several solutions in this thread: http://forums.odforce.net/topic/31600-spiral-unrolling-rolling-animation/?do=findComment&comment=174963

16 I think.
15. ## Pop attract with grains

set targetP, animate targetstiffness. grain_targetp_targetstiffness.hipnc
