# RENDERTOY2 (WIP)
As the final project of Advanced Computer Graphics (Fall 2023, IIIS, Tsinghua Univ. ), RenderToy2 is a completely refactored version of the first generation RenderToy.
RenderToy2 是清华大学交叉信息研究院2023年秋课程《高等计算机图形学》的期末大作业，也是初代 RenderToy 完全重构的迭代版本。

## Implemented
### Rendering Techniques
* BSDF Path Tracing
* Direct Light Sampling (power weighted)
* Approximated Volume Rendering (Single Scattering)
* Motion Blur
* Depth of Field
* HDRI Map (importance sampled)
* SDF Ray Marching via Sphere Tracing
### Sampling Strategies
* Adaptive Sampling
* Multiple Importance Sampling
* Inverse Transform Methods
* Alias Sampling
* Rejection Sampling
* ...
### Material
* Lambertian BRDF
* Oren-Layar BRDF
* Specular BRDF
* Transmissive BSDF
* Principled BSDF
* Alpha Test (testing A channel of RGBA, if given)
* Fresnel
* Beckmann microfacet distribution
* Texture Mapping (similar to pbrt and Cycles, use `ISamplable` to abstract the texture type)
### Geometry
* SAH-BVH
* Normal mapping
* Mixed geometric representation
* Mesh
* SDF
### Post Processing & Visual Effects
* Tone mapping
* Custom aperture (rejection sampled)
* Denoiser using Intel® Open Image Denoise
* Programmable shader to manipulate pixels on images
* Layer-based image composition
* Bitmap font watermark
## Not yet implemented
* ...
## May be implemented
* LOD
* Bidirectional Path Tracing
* Caustics
* GPU Acceleration
* ...
## Requirements
* glm
* OpenImageIO
* assimp
* tbb
* OpenImageDenoise
