whiteroom classroom

特点

积分器(ambient occlusion, path tracing, light tracing, volumetric path tracing, bidirectional path tracing,
stochastic progressive photonmapper, instant radiosity)
材质(lambertian, mirror, dielectric, roughdielectric, roughconduct, substrate)
参与介质渲染(homogeneous and heterogeneous)
光源(area, infinite)
多重重要性采样(mis)
景深(dof)
简单的场景加载(simple scene loader)

依赖库

需要CUDA9.1以上

关于场景

鉴于场景太大，所以只放了一个简单的测试场景供使用，如果需要，可以联系我将其余场景提供给你
