Itasc(IKParam)

base classes — bpy_struct, IKParam

class bpy.types.Itasc(IKParam)

Parameters for the iTaSC IK solver

damping_epsilon

Singular value under which damping is progressively applied (higher values produce results with more stability, less reactivity)

Type

float in [0, 1], default 0.0

damping_max

Maximum damping coefficient when singular value is nearly 0 (higher values produce results with more stability, less reactivity)

Type

float in [0, 1], default 0.0

feedback

Feedback coefficient for error correction, average response time is 1/feedback

Type

float in [0, 100], default 0.0

iterations

Maximum number of iterations for convergence in case of reiteration

Type

int in [0, 1000], default 0

mode

  • ANIMATION Animation – Stateless solver computing pose starting from current action and non-IK constraints.

  • SIMULATION Simulation – State-full solver running in real-time context and ignoring actions and non-IK constraints.

Type

enum in [‘ANIMATION’, ‘SIMULATION’], default ‘ANIMATION’

precision

Precision of convergence in case of reiteration

Type

float in [0, 0.1], default 0.0

reiteration_method

Defines if the solver is allowed to reiterate (converge until precision is met) on none, first or all frames

  • NEVER Never – The solver does not reiterate, not even on first frame (starts from rest pose).

  • INITIAL Initial – The solver reiterates (converges) on the first frame but not on subsequent frame.

  • ALWAYS Always – The solver reiterates (converges) on all frames.

Type

enum in [‘NEVER’, ‘INITIAL’, ‘ALWAYS’], default ‘NEVER’

solver

Solving method selection: automatic damping or manual damping

  • SDLS SDLS – Selective Damped Least Square.

  • DLS DLS – Damped Least Square with Numerical Filtering.

Type

enum in [‘SDLS’, ‘DLS’], default ‘SDLS’

step_count

Divide the frame interval into this many steps

Type

int in [1, 50], default 0

step_max

Higher bound for timestep in second in case of automatic substeps

Type

float in [0, 1], default 0.0

step_min

Lower bound for timestep in second in case of automatic substeps

Type

float in [0, 0.1], default 0.0

use_auto_step

Automatically determine the optimal number of steps for best performance/accuracy trade off

Type

boolean, default False

velocity_max

Maximum joint velocity in radians/second

Type

float in [0, 100], default 0.0
