Filter Settings

The Filter Menu allows users to fine-tune motion filtering parameters to achieve smoother actuator movements and reduce unwanted spikes. The following options can be configured:

Filter Settings

Filter Enabled

• Toggles the filter on or off.

Filter Type

Defines the type of filter applied to actuator movements:

• EMALP (Exponential Moving Average Low Pass Filter)

  • Similar to the filter used in Mover for motion smoothing.

• EMALP & SPIKE

  • Includes both an Exponential Moving Average Low Pass Filter and a Spike Filter to handle sudden movements.

Filter Samples

• Adjusts the intensity of the selected filter.

• A higher value results in smoother movements, but may introduce slight delays.

Spike Filter

The Spike Filter is designed to handle sudden, excessive, and unintended movements. It smooths out extreme motion spikes when they exceed a defined threshold.

Spike Filter Strength

• Determines how aggressively the filter smooths out spikes.

• The smoothing effect increases exponentially (Filter^4) as the spike magnitude exceeds the threshold.

Sorry for wrong orientation will replace later

Spike Window

• The threshold above which the Spike Filter activates.

• 100 roughly corresponds to half the total actuator pulse range.

• A lower value triggers the filter more frequently (e.g., setting it to 1 filters all pulses).

Spike Filter Smoothing (Sp. Filter Smooth)

• Controls how dynamically the Spike Filter responds.

• A low value makes the filter react quickly and sharply when a spike occurs.

• A high value makes the filter increase and decrease gradually, resulting in smoother transitions.

Quick Guide to Setting Up the Spike Filter

Follow these steps to optimize the Spike Filter settings:

1. Start with default factory settings (after a Factory Reset).

2. Generate a motion loop (e.g., a Saw Wave in Mover) with a high amplitude.

   • Alternatively, in a simulation, crash a car into a wall to create a strong actuator response.

3. Reduce the "Spike Window" value until you notice a significant increase in spike intensity.

4. Find a balanced "Spike Window" value that filters unwanted movements without making the rig feel unresponsive.

5. Gradually increase "Spike Filter Strength" and "Spike Window" to fine-tune the damping effect.

6. Use "Sp. Filter Smooth" for fine adjustments.

   • This setting is not critical, but can help with fine-tuning.
