Houdini week 2: particles

  • Alt + left click drag and drop can duplicate node
  • Select all nodes and pressing A, then drag and drop can rearrange the chaotic nodes
  • Pressing J and left mouse button can connect the nodes in a chain
  • Pressing Y and left mouse button can cut off the connections between nodes
  • Arrow left/ right can move forward/ backward one frame, arrow up/ down can play the animation forward/ backward.
  • Command + left go back to last keyframe
  • Green for vector
  • Indigo for float
  • Blue is for integer
  • Blue and indigo have one value, indigo has three

Noise

Timeshift allows us to go to certain frame, just by ctrl+shift+left click deleting the expression first, and then input the certain frame number.

Popnet

  • Popobject is like a container full of particles
  • Popsolver is like a algorithm, it has physical operation calculating what’s happening in dynamics
  • Popsource

Geometry source of popsource should match the number of poppet.

Above is another way to achieve the same effects.

After changing the value of amplitude, it just like a gust of wind blowing the particles away.
