Day 2 Update

  • Built the React Three Fiber app for Task 1 (Week-1/Task-1/r3f/solar-system) with full Vite project setup and base files.
  • Implemented a simple solar system scene in R3F:
    • Added Sun and Earth meshes.
    • Created parent-child hierarchy using a <group ref={orbitRef}> for Earth orbit pivot.
    • Animated orbit with useFrame by rotating the parent group each frame.
  • Added/updated documentation for the day:
    • Added Day 1 summary (Week-1/Days-update/Day1.md).
    • Updated Task 1 notes (Week-1/Task-1/TaskNotes.md) with Vanilla, R3F, and Thob comparison.
    • Added Builder notes (Week-1/Task-1/builder/BuilderNotes.md) including observed warnings/errors and limitations.
  • Key learning: Scene graph parent-child transforms are straightforward in Vanilla and R3F, while Thob showed unstable behavior when changing child local position under parent transforms.
