Scene Graphs

• Why Important:

  • Scene graphs are the backbone of game engines like Unity or Unreal, representing the hierarchical structure of objects.
  • They handle transformations, instancing, and visibility efficiently.

• Learn To:

  • Traverse scene graphs for operations like toggling visibility or applying global transformations.
  • Understand shared nodes (e.g., meshes, materials, lights) and their impact on rendering.

• Why Important:

  • Understanding how vertices, edges, and faces are connected is key for mesh traversal and editing tools.

• Learn To:

  • Identify neighboring vertices or faces (Adjacency Graph).
  • Optimize for loops like edge traversal, normal calculation, or smoothing.

Example Use Cases:

• Finding connected edges for a bevel tool.
• Building edge loops for mesh simplification.
