LightmetricaA research oriented renderer

perim (@hi2p_perim)

特徴

• Renderer for research– Fully based on Veach’s path formulation– Highly extensible– Moderately fast (SIMD optimized)– Unit tested– Various techniques are (supported to be)

implemented

欠点

• Some must-have features for typical rendering is missing or yet to be implemented– Environment light– Filtering– Advanced importance sampling– GPU implementation– Volume rendering

今回用いた手法

• Rendering technique– Bidirectional path tracing (BPT)

[Veach & Guibas 1995]

手描き !

反省

• 優先度• 直前まで実装しようとして失敗• 欲張ろうとするとだめ

Thank you!
