SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Generates physically-inspired, artistically-lit procedural clouds to enrich Three.js scenes, replacing flat skies with volumetric, shader-driven cloudscapes.

Core Features & Use Cases

  • Volumetric raymarching for high-fidelity clouds with lighting, shading, and self-shadowing.
  • Mesh-cluster and billboard cloud paths with WebGL2 fallbacks for broad compatibility.
  • Time-of-day coloring, god rays, and wind-driven drift for dynamic skies.
  • Use cases include skyboxes, weather environments, flight scenes, and atmospheric backdrops.

FAQPage Schema
How do I render volumetric clouds in Three.js?

You can render volumetric clouds in Three.js by applying shader-based raymarching techniques to generate high-fidelity cloudscapes with realistic density, lighting, and self-shadowing. This approach replaces flat skyboxes with dynamic, volumetric geometry.

Does this procedural cloud rendering work with WebGL2 if WebGPU is unavailable?

Yes, volumetric cloud rendering supports WebGL2 fallbacks using mesh-cluster and billboard cloud paths. This ensures broad compatibility across environments where WebGPU support is not available.

Can I simulate day and night cycles with procedural clouds?

Yes, procedural clouds support time-of-day coloring, wind-driven drift, and god rays to simulate dynamic day and night cycles. These shader-based lighting models adjust atmospheric backdrops across different times.

What is the best way to add realistic clouds to a flight scene in Three.js?

The best way to add realistic clouds to a flight scene is using volumetric raymarching, which provides physically-inspired lighting and self-shadowing. This creates high-fidelity atmospheric backdrops suitable for flight environments.

Do I need a specific version of Three.js to use WebGPU raymarching for clouds?

Yes, you need Three.js r170 or later to use WebGPU raymarching for procedural clouds. This version provides the necessary WebGPU support required for the advanced shader-based rendering pipelines.

What are the limitations of using raymarching for procedural cloudscapes?

Raymarching procedural cloudscapes can be computationally intensive, requiring advanced shader pipelines. If performance is a concern, you can utilize the WebGL2 fallback paths with mesh-cluster or billboard clouds for better compatibility.
