Curve editing
- - Animation software (Maya, 3DSMax, Blender, etc) always come with a curve editor.
- - Artists can manually ajust their position, time, and derivatives on curve editor.
-
- - One curve for each scalar parameter
-
- - position \((x,y,z)\)
- - scaling \((s_x,s_y,s_z)\)
- - rotation/quaternion \((q_x,q_y,q_z,q_w)\)
- - Can also use a wrapper function \(w\) to change time \(p(t) = f(w(t))\)
