Introduction

The V-Sekai community needs better rigging and animation tools specifically tailored for VR. The goal is to move beyond the current limitations of traditional approaches.

Objective

Develop an intuitive inverse kinematics (IK) system for VR avatars that removes the need for numerical input, enhancing the user experience.

Proposed Solution

The proposed VR Armature System includes:

  • Handles designed for VR interaction.
  • Visual indicators for joint movement ranges.
  • Straightforward adjustment methods without requiring numbers.

Technical Implementation Steps

  1. Handle Control Design:

    • Craft VR-appropriate ergonomic handles.
    • Track VR controller for handle interaction.

  2. Visual Indicator Development:

    • Visualize joint limits.
    • Update indicators with joint movement.

  3. IK Solver Integration:

    • Employ IK solver for joint positioning.
    • Validate across different avatar models.

  4. Interface & Interaction:

    • Interface design for easy joint manipulation.
    • Implement feedback for joint limit reach.

  5. Testing & Debugging:

    • User testing for intuitive use.
    • Refine system via user feedback.

  6. System Finalization:

    • Establish final iteration post-testing.
    • Optimize for VR performance.

  7. Documentation & Training:

    • Produce user guides and tutorials.
    • Conduct capability and usage training sessions.

Benefits

Implementing this system aims to improve the creation process in VR and establish V-Sekai as a cutting-edge developer of VR tools.

Considerations

The introduction of a new system may require substantial resources and time for users to become familiar with it.

Alternatives Evaluated

Other options, like enhancing existing numerical controls or looking into traditional motion capture technologies, were considered but didn’t meet our immersive needs.

Extended Applications

While focused on VR, this system could also benefit animators using more conventional methods by providing improved interfaces and easier rig manipulation.

Alignment with V-Sekai

It’s crucial for V-Sekai to maintain this project to ensure it meets our quality standards and integrates seamlessly with our core technologies.
