Redflash Renderer

pr33_v6_t3000_s1030_1920x1080

Redflash is a physics-based GPU renderer based on Path Tracing implemented in NVIDIA® OptiX 6.0, which can consistently draw scenes with mixed Polygons and Raymarching.

Redflash は NVIDIA® OptiX 6.0 上で実装したパストレーシングによる物理ベースのGPUレンダラーで、ポリゴンと レイマーチング が混在したシーンを一貫して描画できます。

Note

This is implemented based on optixPathTracer of NVIDIA official OptiX-Samples.

これは、NVIDIA 公式の OptiX-Samples の optixPathTracer をベースにして実装されています。

The actual implementation is in the redflash directory.

実際の実装は redflash ディレクトリ内にあります。
