Identifying design patterns in game engine sprite systems

This is an easy design-patterns question commonly used to assess whether candidates recognise structural patterns in existing codebases. It's the kind of question game-development and graphics teams at companies like Nvidia ask to ensure engineers can read and reason about architectural choices in systems code.

The question presents a concrete implementation—in this case, a visual effect component designed to handle many fine-grained objects efficiently—and asks you to name the pattern. Success depends on understanding the classic Gang of Four patterns, their tradeoffs, and the real-world signals (memory usage, object creation, shared state) that reveal which pattern is in play.

• Structural vs. creational patterns
• Trade-offs between object creation overhead and memory footprint
• Recognising patterns from code intent and constraints
