此着色器执行三种类型的模拟,这些模拟可以一起使用,也可以单独使用:
支持以下散射功能:
color "misss_physical" ( color "material", color "transmission", scalar "ior", vector "absorption_coeff", vector "scattering_coeff", scalar "scale_conversion", scalar "scattering_anisotropy", scalar "depth", integer "max_samples", integer "max_photons", scalar "max_radius", boolean "approx_diffusion", boolean "approx_single_scatter", boolean "approx_multiple_scatter", array light "lights", integer "mode")该着色器为光学特性和调整提供参数。该着色器必须同时作为材质着色器和光子着色器进行应用。
material "misss_physical_phen" ( color "material", color "transmission", scalar "ior", vector "absorption_coeff", vector "scattering_coeff", scalar "scale_conversion", scalar "scattering_anisotropy", scalar "depth", integer "max_samples", integer "max_photons", scalar "max_radius", boolean "approx_diffusion", boolean "approx_single_scatter", boolean "approx_multiple_scatter", array light "lights", integer "mode" ) version 4这是一个与材质和光子窗口进行适当着色器连接的材质现象。其参数和行为与 misss_physical 相同。
