CPU-RTRM
CPU Real-Time Raymarcher is a renderer based on raymarching distance-fields. It runs exclusively on CPU at interactive frame-rates for relatively simple scenes.
It was a project to learn about SIMD, cache-friendly programming and profiling/optimization.

Details
- Developed with C++.
- Raymarching based on sphere tracing.
- Architecture built around SIMD capabilities, using packs of rays. Supports SSE and AVX.
- Naive multi-threading for the extra speed boost.
- Implementation of Blinn-Phong lighting, Ambient Occlusion and fog.
