Hair Displacement

Recommended Posts

Hello folks,

Is there any body knows how does Fur's displacement ? I think the proper processing progress should as following steps,

  1. subdivide geometry
  2. displace geometry & UV,
  3. displace guides hairs onto proper root position,
  4. interpolate instanced hair by dispalcement map and direction on dispaced geometry,
  5. rendering both.

But infering from document

  • Displacement Map Specifies a texture map used to displace the position of each hair.
  • Displace Direction Specifies how to interpret values from the Displacement Map.

I am not sure whether this Displacement function is used as I outlined. So is there any solution for accuracy hair planting on displaced surface ?

Thank you !
