disintegration

+the.Lab works 


  1. To create the disintegration mask over the model, the tutorial below is using “mask from geometry” from houdini v18. 
  1. I’m using the combination of ‘group’ Bounding Objects to create the overlap mask and a “falloff” node to create a blended mask.
  1. the attribute falloff is then taken into an “attribute vop” instead of the attribute mask from the tutorial.

AttributeVOP setup: (distort edge)

bind  
  • attribute = falloff
float to vector
  • visualize just the red channel
subtract turbulent noise
add
  • add back in the original falloff to get rid of turbulence in the upper model
  • this increases the red over 1.0
clamp
  • will clamp value to <= 1
fit
  • to better adjust turbulence
bind export 
  • back out to attribute falloff

AttributeVOP setup: (border)

  • using bind and falloff again
trig function 
  • set to sin 
  • adjust frequency until border forms

  • but sin is calculating from -1 to +1 so we have to clamp it again
bind export
  • to falloff

delete

  • delete by expression - to isolate band geometry
