# Zero-Copy Memory Architecture

### Direct Pointers to GPU Buffers

> Eliminating the JavaScript bottleneck by passing Wasm pointers directly to GPU buffers.

**Moving data between WebAssembly and JavaScript is traditionally a performance bottleneck.** The SCORE framework bypasses this entirely through a custom zero-copy architecture.

### Direct Memory Access

Rather than serializing or copying heavy spatial data across the JS bridge, the engine extracts exact memory pointers directly from the Wasm linear memory.

### GPU Buffer Integration

These pointers are mounted as Float32Arrays and passed directly into the GPU Context Buffers. By eliminating data copying completely, clients experience maximum rendering performance and a significantly lower memory footprint for complex 3D scenes.

### Frequently Asked Questions

#### Q: How does the SCORE framework achieve zero-copy data transfer between WebAssembly and JavaScript?

The SCORE framework bypasses traditional data transfer bottlenecks by extracting exact memory pointers directly from the Wasm linear memory, mounting them as Float32Arrays and passing them into the GPU Context Buffers.

#### Q: What is the primary performance benefit of SCORE's zero-copy architecture?

By eliminating data copying completely, clients experience maximum rendering performance and a significantly lower memory footprint for complex 3D scenes.

#### Q: What traditional bottleneck does the SCORE framework address?

The SCORE framework addresses the traditional performance bottleneck of moving data between WebAssembly and JavaScript.

#### Q: How are memory pointers from Wasm linear memory utilized in the SCORE framework?

Memory pointers extracted directly from Wasm linear memory are mounted as Float32Arrays and passed directly into the GPU Context Buffers.

#### Q: What is the impact of SCORE's zero-copy approach on memory usage for complex 3D scenes?

The zero-copy architecture results in a significantly lower memory footprint for complex 3D scenes.

#### Q: Why is direct memory pointer extraction preferred over serialization or copying for spatial data?

Direct memory pointer extraction is preferred because it avoids serializing or copying heavy spatial data across the JS bridge, which is a traditional performance bottleneck.
