Technical introduction
  •  Linear Blending Skinning (LBS)

  • Dual quaternion Linear Blending (DLB)

  • Benefits
    • eliminates skin collapsing artifacts
    • GPU friendly implementation
    • easy rigging: uses the same model 
    • files as standard linear blend skinning
    • very simple update of a 3D engine
  • Limitations
    • slightly slower than linear blend skinning (in our implementation: 7 more vertex shader instructions)
    • scale/shear is now supported (via two-phase skinning - extra 29 vertex shader instructions)
    • flipping artifacts (skin always goes the shorter way round)
