EMPIRICAL SCOPEBENCHMARKS PRESENTED ON THIS SITE REPRESENT MEASURED EMPIRICAL DATA CONDUCTED UNDER SPECIFIC REFERENCE HARDWARE ENVIRONMENTS. THEY DO NOT CONSTITUTE A FORMAL SERVICE LEVEL AGREEMENT (SLA) OR GUARANTEE OF IDENTICAL RUNTIME ON DIVERGENT HARDWARE.
1. Benchmark Test Rig & Measurement Conditions
All performance metrics, solve times, and speedup ratios reported across this site were gathered under the following controlled environment:
- CPU: AMD Ryzen 5 4600H (6 physical cores, 12 concurrent hardware threads);
- Resolution: 260 × 260 square rendering raster;
- Reference Path Tracer: Multi-threaded CPU Monte Carlo path tracer executed to 384 samples per pixel (spp);
- Operating System: Clean x86_64 Linux kernel environment without competing CPU background tasks;
- Compiler Flags: Rust
cargo build --release with standard opt-level = 3.
Actual execution speeds on your machine will vary depending on your specific CPU microarchitecture, thermal throttling limits, cache sizes (L1/L2/L3), memory bandwidth, and active background processes.
2. The SSIM Ceiling Caveat (Structural Similarity)
The Structural Similarity Index (SSIM) values in our benchmark table (e.g. 0.854 for Cornell Box) must be evaluated against the theoretical analytical ceiling of 0.892, rather than an arbitrary 1.0.
Why? Interflect solves diffuse radiosity using piecewise-constant surfel discs, while the path tracer computes continuous Monte Carlo ray intersections. The slight delta is an intrinsic mathematical characteristic of surfel discretization, not un-converged noise. As documented in TESTING.md, reading SSIM as "85% accurate" is a fundamental category error.
3. No Warranty of Fitness for Life-Safety Applications
Interflect is distributed as a research and developer tool. It is NOT certified as illumination engineering simulation software for architectural building code compliance, occupational safety (OSHA) lighting standards, or medical device design.
Under no circumstances should radiance values computed by Interflect be used to certify emergency egress illumination, surgical theater lighting, or vehicular headlamp safety standards.
