WebGPU represents a fundamental shift in how we approach graphics on the web. Unlike WebGL, which is based on OpenGL ES, WebGPU is designed from the ground up for modern GPU architectures.

Key Advantages

Compute Shaders

For the first time on the web, we have access to general-purpose GPU computing. This enables particle systems, physics simulations, and AI inference directly in the browser.

Better Performance

WebGPU reduces driver overhead significantly. Command buffers can be built on worker threads and submitted efficiently, leading to better frame rates and lower latency.

Modern API Design

The API reflects lessons learned from Vulkan, Metal, and D3D12:

• Explicit resource management
• Pipeline state objects
• Render passes and attachments

Three.js Integration

Three.js has a WebGPU renderer in development. The transition path involves:

1. TSL (Three Shading Language) - Write shaders once, target WebGL or WebGPU
2. Node Materials - Build materials programmatically
3. Compute Integration - Access GPU compute from Three.js

When to Adopt

WebGPU is available in Chrome and will soon ship in Firefox and Safari. For production apps, consider a fallback strategy that detects WebGPU support and falls back to WebGL.
