SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the critical need to manage and optimize the performance of 3D scenes within the Myelin simulator, ensuring a smooth and usable learner experience on target hardware by adhering to strict performance budgets.

Core Features & Use Cases

  • Performance Budgeting: Defines authoritative face counts, texture resolutions, and memory ceilings for scene geometry, LODs, and textures.
  • Adaptive Quality: Supports multiple quality tiers (MINIMUM, HD, HD_PLUS, UHD) with adaptive downgrading logic.
  • LOD System: Provides guidelines for implementing Level of Detail (LOD) for objects using Three.js LOD objects.
  • Instancing & Culling: Details the use of THREE.InstancedMesh for repeated geometry and emphasizes the importance of frustum culling.
  • Asset Loading Strategy: Outlines a two-phase loading approach for faster scene startup.
  • Use Case: When creating or modifying any 3D assets for the Myelin simulator, use this skill to ensure all geometry, textures, and LODs comply with the defined performance budgets, preventing frame rate drops and ensuring the application remains responsive.

Quick Start

Load this skill before writing any geometry, LOD, or instancing code to ensure adherence to performance budgets.

Frequently Asked Questions about lod-performance-budget

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I optimize 3D scene performance using Level of Detail and performance budgets?▼

Optimize 3D scene performance by enforcing strict face counts, texture resolutions, and memory ceilings using a Level of Detail (LOD) system. This approach manages adaptive quality logic across multiple hardware tiers to prevent frame rate drops.

How do I implement LOD objects and frustum culling in Three.js?▼

Implement LOD objects and frustum culling in Three.js using built-in `LOD` objects for distance-based geometry swapping and `THREE.InstancedMesh` for repeated geometry. This combination reduces draw calls and maintains responsive rendering.

What is adaptive quality downgrading and when do I need it for 3D rendering?▼

Adaptive quality downgrading dynamically lowers 3D rendering settings across defined quality tiers like MINIMUM, HD, HD_PLUS, and UHD. You need it to maintain usable frame rates when target hardware struggles with default scene complexity.

What is the best way to speed up 3D scene startup time for asset loading?▼

Speed up 3D scene startup time by using a two-phase asset loading strategy. This approach prioritizes essential geometry and textures first, ensuring the application meets startup time targets before loading remaining assets.

Does this performance budgeting approach work for managing texture resolutions and memory ceilings?▼

Performance budgeting explicitly works for managing texture resolutions and memory ceilings. It defines authoritative limits for scene geometry and textures, ensuring all 3D assets comply with hardware constraints to prevent memory overload.

Why does my 3D scene experience frame rate drops on lower hardware tiers?▼

3D scenes experience frame rate drops on lower hardware tiers when geometry and textures exceed performance budgets. Enforcing face counts and utilizing adaptive quality downgrading logic ensures the application remains responsive across varying hardware capabilities.
