Spherical Harmonicsを用いて、リアルタイムに動画のような描画ができる。

After the conversion I proceed as if it would be precomputed radiance transfer and calculate the final lighting by calculating the dot product between the basis functions, the lighting coefficients and the transfer coefficients and get the irradiance.

最初に時間のかかる計算を終わらせ、あとはdot productを計算することで、様々な特性での計算をリアルタイムに行っている。
